Western philosophy is the philosophical thought and work of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with Greek philosophy of the pre-Socratics such as Thales (c. 624 – c. 546 BC) and Pythagoras (c. 570 – c. 495 BC), and eventually covering a large area of the globe. The word philosophy itself originated from the Ancient Greek philosophía (φιλοσοφία), literally, "the love of wisdom" (φιλεῖν phileîn, "to love" and σοφία sophía , "wisdom").
Philosophy is the study of general and fundamental questions about existence, knowledge, values, reason, mind, and language. Such questions are often posed as problems to be studied or resolved. The term was probably coined by Pythagoras. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? Philosophers also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust? Do humans have free will?
The Western world, also known as the West, refers to various nations depending on the context, most often including at least parts of Europe, Australasia, and the Americas, with the status of Latin America disputed by some. There are many accepted definitions, all closely interrelated. The Western world is also known as the Occident, in contrast to the Orient, or Eastern world.
Western culture, sometimes equated with Western civilization, Occidental culture, the Western world, Western society, and European civilization, is the heritage of social norms, ethical values, traditional customs, belief systems, political systems, artifacts and technologies that originated in or are associated with Europe. The term also applies beyond Europe to countries and cultures whose histories are strongly connected to Europe by immigration, colonization, or influence. For example, Western culture includes countries in the Americas and Australasia, whose language and demographic ethnicity majorities are European. Western culture has its roots in Greco-Roman culture from before 800 B.C.E..
The scope of philosophy in the ancient understanding, and the writings of (at least some of) the ancient philosophers, were all intellectual endeavors. This included the problems of philosophy as they are understood today; but it also included many other disciplines, such as pure mathematics and natural sciences such as physics, astronomy, and biology (Aristotle, for example, wrote on all of these topics).
A philosopher is someone who practices philosophy. The term "philosopher" comes from the Ancient Greek, φιλόσοφος (philosophos), meaning "lover of wisdom". The coining of the term has been attributed to the Greek thinker Pythagoras.
Pure mathematics is the study of mathematical concepts independently of any application outside mathematics. These concepts may originate in real-world concerns, and the results obtained may later turn out to be useful for practical applications, but the pure mathematicians are not primarily motivated by such applications. Instead, the appeal is attributed to the intellectual challenge and aesthetic beauty of working out the logical consequences of basic principles.
Natural science is a branch of science concerned with the description, prediction, and understanding of natural phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances.
In the pre-Socratic period, ancient philosophers first articulated questions about the "archḗ" (the cause or first principle) of the universe. Western philosophy is generally said to begin in the Greek cities of western Asia Minor, or Ionia, with Thales of Miletus, who was active c. 585 BC and was responsible for the opaque dictum, "all is water." His most noted students were respectively Anaximander ("all is apeiron", meaning roughly, "the unlimited") and Anaximenes of Miletus ("all is air").
A number of early Greek philosophers active before and during the time of Socrates are collectively known as the pre-Socratics. Their inquiries spanned the workings of the natural world as well as human society, ethics, and religion, seeking explanations based on natural principles rather than the actions of supernatural gods. They introduced to the West the notion of the world as a kosmos, an ordered arrangement that could be understood via rational inquiry.
The Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. While the spatial size of the entire Universe is unknown, it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light years in diameter. In various multiverse hypotheses, a universe is one of many causally disconnected constituent parts of a larger multiverse, which itself comprises all of space and time and its contents.
Ionia was an ancient region on the central part of the western coast of Anatolia in present-day Turkey, the region nearest İzmir, which was historically Smyrna. It consisted of the northernmost territories of the Ionian League of Greek settlements. Never a unified state, it was named after the Ionian tribe who, in the Archaic Period, settled mainly the shores and islands of the Aegean Sea. Ionian states were identified by tradition and by their use of Eastern Greek.
Pythagoras, from the island of Samos off the coast of Ionia, later lived in Croton in southern Italy (Magna Graecia). Pythagoreans hold that "all is number," giving formal accounts in contrast to the previous material of the Ionians. They also believe in metempsychosis, the transmigration of souls, or reincarnation.
Pythagoras of Samos was an ancient Ionian Greek philosopher and the eponymous founder of Pythagoreanism. His political and religious teachings were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, Western philosophy. Knowledge of his life is clouded by legend, but he appears to have been the son of Mnesarchus, a seal engraver on the island of Samos. Modern scholars disagree regarding Pythagoras's education and influences, but they do agree that, around 530 BC, he travelled to Croton, where he founded a school in which initiates were sworn to secrecy and lived a communal, ascetic lifestyle. This lifestyle entailed a number of dietary prohibitions, traditionally said to have included vegetarianism, although modern scholars doubt that he ever advocated for complete vegetarianism.
Samos is a Greek island in the eastern Aegean Sea, south of Chios, north of Patmos and the Dodecanese, and off the coast of Asia Minor, from which it is separated by the 1.6-kilometre (1.0 mi)-wide Mycale Strait. It is also a separate regional unit of the North Aegean region, and the only municipality of the regional unit.
Crotone is a city and comune in Calabria. Founded c. 710 BC as the Achaean colony of Kroton, it was known as Cotrone from the Middle Ages until 1928, when its name was changed to the current one. In 1992, it became the capital of the newly established Province of Crotone. As of August 2018, its population was about 65,000.
A key figure in Greek philosophy is Socrates. Socrates studied under several Sophists but transformed Greek philosophy into a branch of philosophy that is still pursued today. It is said that following a visit to the Oracle of Delphi he spent much of his life questioning anyone in Athens who would engage him, in order to disprove the oracular prophecy that there would be no man wiser than Socrates.Socrates used a critical approach called the "elenchus" or Socratic method to examine people's views. He aimed to study human things: the good life, justice, beauty, and virtue. Although Socrates wrote nothing himself, some of his many disciples wrote down his conversations. He was tried for corrupting the youth and impiety by the Greek democracy. He was found guilty and sentenced to death. Although his friends offered to help him escape from prison, he chose to remain in Athens and abide by his principles. His execution consisted of drinking the poison hemlock and he died in 399 BC.
Socrates was a classical Greek (Athenian) philosopher credited as one of the founders of Western philosophy, and as being the first moral philosopher, of the Western ethical tradition of thought. An enigmatic figure, he made no writings, and is known chiefly through the accounts of classical writers writing after his lifetime, particularly his students Plato and Xenophon. Other sources include the contemporaneous Antisthenes, Aristippus, and Aeschines of Sphettos. Aristophanes, a playwright, is the main contemporary author to have written plays mentioning Socrates during Socrates' lifetime, though a fragment of Ion of Chios' Travel Journal provides important information about Socrates' youth.
The Socratic method, also known as method of Elenchus, elenctic method, or Socratic debate, is a form of cooperative argumentative dialogue between individuals, based on asking and answering questions to stimulate critical thinking and to draw out ideas and underlying presuppositions. It is a dialectical method, involving a discussion in which the defense of one point of view is questioned; one participant may lead another to contradict themselves in some way, thus weakening the defender's point. This method is named after the Classical Greek philosopher Socrates and is introduced by him in Plato's Theaetetus as midwifery (maieutics) because it is employed to bring out definitions implicit in the interlocutors' beliefs, or to help them further their understanding.
Plato was a student of Socrates. Plato founded the Academy of Athens and wrote a number of dialogues, which applied the Socratic method of inquiry to examine philosophical problems. Some central ideas of Plato's dialogues are the immortality of the soul, the benefits of being just, that evil is ignorance, and the Theory of Forms. Forms are universal properties that constitute true reality and contrast with the changeable material things he called "becoming".
Plato was an Athenian philosopher during the Classical period in Ancient Greece, founder of the Platonist school of thought, and the Academy, the first institution of higher learning in the Western world.
An academy is an institution of secondary education, higher learning, research, or honorary membership. Academia is the worldwide group composed of professors and researchers at institutes of higher learning.
Socratic dialogue is a genre of literary prose developed in Greece at the turn of the fourth century BC. It is preserved in the works of Plato and Xenophon. The discussion of moral and philosophical problems between two or more characters in a dialogue is an illustration of one version of the Socratic method. The dialogues are either dramatic or narrative and Socrates is often the main participant.
Aristotle was a pupil of Plato. Aristotle was perhaps the first truly systematic philosopher and scientist. He wrote about physics, biology, zoology, metaphysics, aesthetics, poetry, theater, music, rhetoric, politics and logic. Aristotelian logic was the first type of logic to attempt to categorize every valid syllogism. Aristotle tutored Alexander the Great, who in turn conquered much of the ancient world at a rapid pace. Hellenization and Aristotelian philosophy exercised considerable influence on almost all subsequent Western and Middle Eastern philosophers, including Hellenistic, Roman, Byzantine, Western medieval, Jewish, and Islamic thinkers.
Following Socrates a variety of schools of thought emerged. In addition to Plato's Academy and Aristotle's Peripatetic school, other schools of thought derived from Socrates included the Academic Skeptics, Cynics, Cyrenaics, and Stoics. In addition, two non-Socratic schools derived from the teachings of Socrates' contemporary, Democritus flourished, Pyrrhonism and Epicureanism.
Medieval philosophy is the philosophy of Western Europe and the Middle East during the Middle Ages, roughly extending from the Christianization of the Roman Empire until the Renaissance.Medieval philosophy is defined partly by the rediscovery and further development of classical Greek and Hellenistic philosophy, and partly by the need to address theological problems and to integrate the then widespread sacred doctrines of Abrahamic religion (Islam, Judaism, and Christianity) with secular learning. Early medieval philosophy was influenced by the likes of Stoicism, Neoplatonism, but, above all, the philosophy of Plato himself.
Some problems discussed throughout this period are the relation of faith to reason, the existence and unity of God, the object of theology and metaphysics, the problems of knowledge, of universals, and of individuation. The prominent figure of this period was Augustine of Hippo (one of the most important Church Fathers in Western Christianity) who adopted Plato's thought and Christianized it in the 4th century and whose influence dominated medieval philosophy perhaps up to end of the era but was checked with the arrival of Aristotle's texts. Augustinianism was the preferred starting point for most philosophers (including Anselm of Canterbury, the father of scholasticism) up until the 13th century.
The Carolingian Renaissance of the 8th and 9th century was fed by Church missionaries travelling from Ireland, most notably John Scotus Eriugena, a Neoplatonic philosopher.
The modern university system has roots in the European medieval university, which was created in Italy and evolved from Catholic Cathedral schools for the clergy during the High Middle Ages.
Thomas Aquinas, an academic philosopher and the father of Thomism, was immensely influential in Catholic Europe; he placed a great emphasis on reason and argumentation, and was one of the first to use the new translation of Aristotle's metaphysical and epistemological writing.
Philosophers from the Middle Ages include the Christian philosophers Augustine of Hippo, Boethius, Anselm, Gilbert de la Porrée, Peter Abelard, Roger Bacon, Bonaventure, Thomas Aquinas, Duns Scotus, William of Ockham and Jean Buridan; the Jewish philosophers Maimonides and Gersonides; and the Muslim philosophers Alkindus, Alfarabi, Alhazen, Avicenna, Algazel, Avempace, Abubacer, Ibn Khaldūn, and Averroes. The medieval tradition of scholasticism continued to flourish as late as the 17th century, in figures such as Francisco Suárez and John of St. Thomas.
The Renaissance ("rebirth") was a period of transition between the Middle Ages and modern thought,in which the recovery of classical texts helped shift philosophical interests away from technical studies in logic, metaphysics, and theology towards eclectic inquiries into morality, philology, and mysticism. The study of the classics and the humane arts generally, such as history and literature, enjoyed a scholarly interest hitherto unknown in Christendom, a tendency referred to as humanism. Displacing the medieval interest in metaphysics and logic, the humanists followed Petrarch in making man and his virtues the focus of philosophy.
At the point of passage from Renaissance into early/classical modern philosophy, the dialogue was used as a primary style of writing by Renaissance philosophers, such as Giordano Bruno.
How much of Renaissance intellectual history is part of modern philosophy is disputed.
The term "modern philosophy" has multiple usages. For example, Thomas Hobbes is sometimes considered the first modern philosopher because he applied a systematic method to political philosophy.By contrast, René Descartes is often considered the first modern philosopher because he grounded his philosophy in problems of knowledge, rather than problems of metaphysics.
Modern philosophy and especially Enlightenment philosophyis distinguished by its increasing independence from traditional authorities such as the Church, academia, and Aristotelianism; a new focus on the foundations of knowledge and metaphysical system-building; and the emergence of modern physics out of natural philosophy.
Some central topics of Western philosophy in its early modern (also classical modern)period include the nature of the mind and its relation to the body, the implications of the new natural sciences for traditional theological topics such as free will and God, and the emergence of a secular basis for moral and political philosophy. These trends first distinctively coalesce in Francis Bacon's call for a new, empirical program for expanding knowledge, and soon found massively influential form in the mechanical physics and rationalist metaphysics of René Descartes.
Other notable modern philosophers include Baruch Spinoza, Gottfried Wilhelm Leibniz, John Locke, George Berkeley, David Hume, and Immanuel Kant.Many other contributors were philosophers, scientists, medical doctors, and politicians. A short list includes Galileo Galilei, Pierre Gassendi, Blaise Pascal, Nicolas Malebranche, Antonie van Leeuwenhoek, Christiaan Huygens, Isaac Newton, Christian Wolff, Montesquieu, Pierre Bayle, Thomas Reid, Jean le Rond d'Alembert, Adam Smith, and Jean-Jacques Rousseau.
The approximate end of the early modern period is most often identified with Immanuel Kant's systematic attempt to limit metaphysics, justify scientific knowledge, and reconcile both of these with morality and freedom.
Late modern philosophy is usually considered to begin around the pivotal year of 1781, when Gotthold Ephraim Lessing died and Kant's Critique of Pure Reason appeared.
German philosophy exercised broad influence in this century, owing in part to the dominance of the German university system.German idealists, such as Johann Gottlieb Fichte, Friedrich Wilhelm Joseph Schelling, Georg Wilhelm Friedrich Hegel, and the members of Jena Romanticism (Friedrich Hölderlin, Novalis, and Karl Wilhelm Friedrich Schlegel), transformed the work of Kant by maintaining that the world is constituted by a rational or mind-like process, and as such is entirely knowable. Arthur Schopenhauer's identification of this world-constituting process as an irrational will to live influenced later 19th- and early 20th-century thinking, such as the work of Friedrich Nietzsche.
The 19th century took the radical notions of self-organization and intrinsic order from Goethe and Kantian metaphysics, and proceeded to produce a long elaboration on the tension between systematization and organic development. Foremost was the work of Hegel, whose Phenomenology of Spirit (1807) and Science of Logic (1813–16) produced a "dialectical" framework for ordering of knowledge.
As with the 18th century, developments in science arose from philosophy and also challenged philosophy: most importantly the work of Charles Darwin, which was based on the idea of organic self-regulation found in philosophers such as Smith, but fundamentally challenged established conceptions.
After Hegel's death in 1831, 19th-century philosophy largely turned against idealism in favor of varieties of philosophical naturalism, such as the positivism of Auguste Comte, the empiricism of John Stuart Mill, and the historical materialism of Karl Marx. Logic began a period of its most significant advances since the inception of the discipline, as increasing mathematical precision opened entire fields of inference to formalization in the work of George Boole and Gottlob Frege.Other philosophers who initiated lines of thought that would continue to shape philosophy into the 20th century include:
The three major contemporary approaches to academic philosophy are analytic philosophy, continental philosophy and pragmatism.They are neither exhaustive nor mutually exclusive.
The 20th century deals with the upheavals produced by a series of conflicts within philosophical discourse over the basis of knowledge, with classical certainties overthrown, and new social, economic, scientific and logical problems. 20th century philosophy was set for a series of attempts to reform and preserve, and to alter or abolish, older knowledge systems. Seminal figures include Bertrand Russell, Ludwig Wittgenstein, Edmund Husserl, Martin Heidegger, and Jean-Paul Sartre. The publication of Husserl's Logical Investigations (1900–1) and Russell's The Principles of Mathematics (1903) is considered to mark the beginning of 20th-century philosophy.The 20th century also saw the increasing professionalization of the discipline and the beginning of the current (contemporary) era of philosophy.
Since the Second World War, contemporary philosophy has been divided mostly into analytic and continental traditions; the former carried in the English speaking world and the latter on the continent of Europe. The perceived conflict between continental and analytic schools of philosophy remains prominent, despite increasing skepticism regarding the distinction's usefulness.
In the English-speaking world, analytic philosophy became the dominant school for much of the 20th century. The term "analytic philosophy" roughly designates a group of philosophical methods that stress detailed argumentation, attention to semantics, use of classical logic and non-classical logics and clarity of meaning above all other criteria. Though the movement has broadened, it was a cohesive school in the first half of the century. Analytic philosophers were shaped strongly by logical positivism, united by the notion that philosophical problems could and should be solved by attention to logic and language.
Bertrand Russell and G.E. Moore are also often counted as founders of analytic philosophy, beginning with their rejection of British idealism, their defense of realism and the emphasis they laid on the legitimacy of analysis. Russell's classic works The Principles of Mathematics ,"On Denoting" and Principia Mathematica (with Alfred North Whitehead), aside from greatly promoting the use of mathematical logic in philosophy, set the ground for much of the research program in the early stages of the analytic tradition, emphasizing such problems as: the reference of proper names, whether 'existence' is a property, the nature of propositions, the analysis of definite descriptions, and discussions on the foundations of mathematics. These works also explored issues of ontological commitment and metaphysical problems regarding time, the nature of matter, mind, persistence and change, which Russell often tackled with the aid of mathematical logic.
Gottlob Frege's The Foundations of Arithmetic (1884) was the first analytic work, according to Michael Dummett (Origins of Analytical Philosophy, 1993). Frege took "the linguistic turn," analyzing philosophical problems through language. Some analytic philosophers held that philosophical problems arise through misuse of language or because of misunderstandings of the logic of human language.
In 1921, Ludwig Wittgenstein, who studied under Russell at Cambridge, published his Tractatus Logico-Philosophicus , which gave a rigidly "logical" account of linguistic and philosophical issues. Years later, he reversed a number of the positions he set out in the Tractatus, in for example his second major work, Philosophical Investigations (1953). Investigations was influential in the development of "ordinary language philosophy," which was promoted by Gilbert Ryle, J.L. Austin, and a few others.
In the United States, meanwhile, the philosophy of Willard Van Orman Quine was having a major influence, with the paper "Two Dogmas of Empiricism". In that paper Quine criticizes the distinction between analytic and synthetic statements, arguing that a clear conception of analyticity is unattainable.
Notable students of Quine include Donald Davidson and Daniel Dennett. The later work of Russell and the philosophy of Willard Van Orman Quine are influential exemplars of the naturalist approach dominant in the second half of the 20th century. But the diversity of analytic philosophy from the 1970s onward defies easy generalization: the naturalism of Quine and his epigoni was in some precincts superseded by a "new metaphysics" of possible worlds, as in the influential work of David Lewis. Recently, the experimental philosophy movement has sought to reappraise philosophical problems through social science research techniques.
Some influential figures in contemporary analytic philosophy are: Timothy Williamson, David Lewis, John Searle, Thomas Nagel, Hilary Putnam, Michael Dummett, John McDowell, Saul Kripke, Peter van Inwagen, and Patricia Churchland.
Analytic philosophy has sometimes been accused of not contributing to the political debate or to traditional questions in aesthetics. However, with the appearance of A Theory of Justice by John Rawls and Anarchy, State, and Utopia by Robert Nozick, analytic political philosophy acquired respectability. Analytic philosophers have also shown depth in their investigations of aesthetics, with Roger Scruton, Nelson Goodman, Arthur Danto and others developing the subject to its current shape.
Continental philosophy is a set of 19th- and 20th-century philosophical traditions from mainland Europe. 20th-century movements such as German idealism, phenomenology, existentialism, modern hermeneutics, critical theory, structuralism, post-structuralism and others are included within this loose category. While identifying any non-trivial common factor in all these schools of thought is bound to be controversial, Michael E. Rosen has hypothesized a few common continental themes: that the natural sciences cannot replace the human sciences; that the thinker is affected by the conditions of experience (one's place and time in history); that philosophy is both theoretical and practical; that metaphilosophy or reflection upon the methods and nature of philosophy itself is an important part of philosophy proper.
The founder of phenomenology, Edmund Husserl, sought to study consciousness as experienced from a first-person perspective, while Martin Heidegger drew on the ideas of Kierkegaard, Nietzsche, and Husserl to propose an unconventional existential approach to ontology.
Phenomenologically oriented metaphysics undergirded existentialism—Martin Heidegger, Jean-Paul Sartre, Maurice Merleau-Ponty, Albert Camus—and finally post-structuralism—Gilles Deleuze, Jean-François Lyotard (best known for his articulation of postmodernism), Michel Foucault, Jacques Derrida (best known for developing a form of semiotic analysis known as deconstruction). The psychoanalytic work of Sigmund Freud, Carl Jung, Jacques Lacan, Julia Kristeva, and others has also been influential in contemporary continental thought. Conversely, some philosophers have attempted to define and rehabilitate older traditions of philosophy. Most notably, Hans-Georg Gadamer and Alasdair MacIntyre have both, albeit in different ways, revived the tradition of Aristotelianism.
Existentialism is a term applied to the work of a number of late 19th- and 20th-century philosophers who, despite profound doctrinal differences,shared the belief that philosophical thinking begins with the human subject—not merely the thinking subject, but the acting, feeling, living human individual. In existentialism, the individual's starting point is characterized by what has been called "the existential attitude", or a sense of disorientation and confusion in the face of an apparently meaningless or absurd world. Many existentialists have also regarded traditional systematic or academic philosophy, in both style and content, as too abstract and remote from concrete human experience.
Although they did not use the term, the 19th-century philosophers Søren Kierkegaard and Friedrich Nietzsche are widely regarded as the fathers of existentialism. Their influence, however, has extended beyond existentialist thought.
Transcendental idealism, advocated by Immanuel Kant, is the view that there are limits on what can be understood, since there is much that cannot be brought under the conditions of objective judgment. Kant wrote his Critique of Pure Reason (1781–1787) in an attempt to reconcile the conflicting approaches of rationalism and empiricism, and to establish a new groundwork for studying metaphysics. Although Kant held that objective knowledge of the world required the mind to impose a conceptual or categorical framework on the stream of pure sensory data—a framework including space and time themselves—he maintained that things-in-themselves existed independently of human perceptions and judgments; he was therefore not an idealist in any simple sense. Kant's account of things-in-themselves is both controversial and highly complex. Continuing his work, Johann Gottlieb Fichte and Friedrich Schelling dispensed with belief in the independent existence of the world, and created a thoroughgoing idealist philosophy.
The most notable work of this German idealism was G.W.F. Hegel's Phenomenology of Spirit , of 1807. Hegel admitted his ideas were not new, but that all the previous philosophies had been incomplete. His goal was to correctly finish their job. Hegel asserts that the twin aims of philosophy are to account for the contradictions apparent in human experience (which arise, for instance, out of the supposed contradictions between "being" and "not being"), and also simultaneously to resolve and preserve these contradictions by showing their compatibility at a higher level of examination ("being" and "not being" are resolved with "becoming"). This program of acceptance and reconciliation of contradictions is known as the "Hegelian dialectic".
Philosophers influenced by Hegel include Ludwig Andreas Feuerbach, who coined the term projection as pertaining to humans' inability to recognize anything in the external world without projecting qualities of ourselves upon those things; Karl Marx; Friedrich Engels; and the British idealists, notably T.H. Green, J.M.E. McTaggart and F.H. Bradley. Few 20th-century philosophers have embraced idealism. However, quite a few have embraced Hegelian dialectic. Immanuel Kant's "Copernican Turn" also remains an important philosophical concept today.
Marxism is a method of socioeconomic analysis, originating from Karl Marx and Friedrich Engels. It analyzes class relations and societal conflict using a materialist interpretation of historical development and a dialectical view of social transformation. Marxist analyses and methodologies influenced political ideologies and social movements. Marxist understandings of history and society were adopted by academics in archaeology, anthropology, media studies, political science, theater, history, sociology, art history and theory, cultural studies, education, economics, geography, literary criticism, aesthetics, critical psychology and philosophy.
Edmund Husserl's phenomenology was an ambitious attempt to lay the foundations for an account of the structure of conscious experience in general.An important part of Husserl's phenomenological project was to show that all conscious acts are directed at or about objective content, a feature that Husserl called intentionality . Husserl published only a few works in his lifetime, which treat phenomenology mainly in abstract methodological terms; but he left an enormous quantity of unpublished concrete analyses. Husserl's work was immediately influential in Germany, with the foundation of phenomenological schools in Munich and Göttingen. Phenomenology later achieved international fame through the work of such philosophers as Martin Heidegger (formerly Husserl's research assistant), Maurice Merleau-Ponty, and Jean-Paul Sartre. Through the work of Heidegger and Sartre, Husserl's focus on subjective experience influenced aspects of existentialism.
Inaugurated by the linguist Ferdinand de Saussure, structuralism sought to clarify systems of signs through analyzing the discourses they both limit and make possible. Saussure conceived of the sign as being delimited by all the other signs in the system, and ideas as being incapable of existence prior to linguistic structure, which articulates thought. This led continental thought away from humanism, and toward what was termed the decentering of man: language is no longer spoken by man to express a true inner self, but language speaks man.
Structuralism sought the province of a hard science, but its positivism soon came under fire by post-structuralism, a wide field of thinkers, some of whom were once themselves structuralists, but later came to criticize it. Structuralists believed they could analyze systems from an external, objective standing, for example, but the poststructuralists argued that this is incorrect, that one cannot transcend structures and thus analysis is itself determined by what it examines. While the distinction between the signifier and signified was treated as crystalline by structuralists, poststructuralists asserted that every attempt to grasp the signified results in more signifiers, so meaning is always in a state of being deferred, making an ultimate interpretation impossible.
Structuralism came to dominate continental philosophy throughout the 1960s and early 1970s, encompassing thinkers as diverse as Claude Lévi-Strauss, Roland Barthes and Jacques Lacan. Post-structuralism came to predominate from the 1970s onwards, including thinkers such as Michel Foucault, Jacques Derrida, Gilles Deleuze and even Roland Barthes; it incorporated a critique of structuralism's limitations.
Pragmatism is a philosophical tradition that began in the United States around 1870.It asserts that the truth of beliefs consists in their usefulness and efficacy rather than their correspondence with reality. Charles Sanders Peirce and William James were its co-founders and it was later modified by John Dewey as instrumentalism. Since the usefulness of any belief at any time might be contingent on circumstance, Peirce and James conceptualized final truth as something established only by the future, final settlement of all opinion.
Pragmatism attempted to find a scientific concept of truth that does not depend on personal insight (revelation) or reference to some metaphysical realm. It interpreted the meaning of a statement by the effect its acceptance would have on practice. Inquiry taken far enough is thus the only path to truth.
For Peirce commitment to inquiry was essential to truth-finding, implied by the idea and hope that inquiry is not fruitless. The interpretation of these principles has been subject to discussion ever since. Peirce's maxim of pragmatism is, "Consider what effects, which might conceivably have practical bearings, we conceive the object of our conception to have. Then, our conception of these effects is the whole of our conception of the object."
Critics accused pragmatism falling victim to a simple fallacy: that because something that is true proves useful, that usefulness is an appropriate basis for its truthfulness.Pragmatist thinkers include Dewey, George Santayana, and C. I. Lewis.
Pragmatism was later worked on by neopragmatists Richard Rorty (who was the first to develop neopragmatist philosophy in his Philosophy and the Mirror of Nature (1979)),Hilary Putnam, W. V. O. Quine, and Donald Davidson. Neopragmatism has been described as a bridge between analytic and continental philosophy.
Process philosophy is a tradition beginning with Alfred North Whitehead, who began teaching and writing on process and metaphysics when he joined Harvard University in 1924.This tradition identifies metaphysical reality with change.
Process philosophy is sometimes classified as closer to continental philosophy than analytic philosophy, because it is usually only taught in continental departments.However, other sources state that process philosophy should be placed somewhere in the middle between the poles of analytic versus continental methods in contemporary philosophy.
Largely Aristotelian in its approach and content, Thomism is a philosophical tradition that follows the writings of Thomas Aquinas. His work has been read, studied and disputed since the 13th century, especially by Roman Catholics. Aquinas enjoyed a revived mainstream interest beginning in contemporary philosophy, among both atheists (Philippa Foot) and theists (Elizabeth Anscombe).Thomist philosophers tend to be rationalists in epistemology, as well as metaphysical realists and virtue ethicists. They claim that humans are rational animals whose good can be known by reason that can be achieved by the will. Thomists argue that soul or psyche is real and immaterial but inseparable from matter in organisms. Soul is the form of the body. Thomists accept Aristotle's causes as natural, including teleological or final causes. In this way, although Aquinas argued that whatever is in the intellect begins in the senses, natural teleology can be discerned with the senses and abstracted from nature through induction.
Contemporary Thomism encompasses multiple variants, from neo-scholasticism to existential Thomism.
The so-called new Natural lawyers like Germain Grisez and Robert P. George applied Thomistic legal principles to contemporary ethical debates, while Freeman proposed that Thomism's cognition was most compatible with neurodynamics. Analytical Thomism (John Joseph Haldane) encourages dialogue between analytic philosophy and broadly Aristotelian philosophy of mind, psychology and hylomorphic metaphysics.Other contemporary Thomists include Stump, MacIntyre and Finnis.
Western philosophers have often been divided into some major branches, or schools, based either on the questions typically addressed by people working in different parts of the field, or notions of ideological undercurrents. In the ancient world, the most influential division of the subject was the Stoics' division of philosophy into logic, ethics, and physics (conceived as the study of the nature of the world, and including both natural science and metaphysics). In contemporary philosophy, specialties within the field are more commonly divided into metaphysics, epistemology, ethics and aesthetics (the latter two of which together comprise axiology, or value theory). Logic is sometimes included as a main branch of philosophy, sometimes as a separate science philosophers happen to work on, and sometimes just as a characteristically philosophical method applying to all branches of philosophy.
Within these broad branches there are now numerous sub-disciplines of philosophy. At the broadest level there is the division between analytic (the English-speaking world and Nordic countries) and continental philosophy (in the rest of Europe). For continental philosophy subdividing philosophy between "experts" is problematic for the very nature of the interdisciplinary task of philosophy itself; however, for most of analytic philosophy further divisions simplify the task for philosophers in each area.
The interest in particular sub-disciplines waxes and wanes over time; sometimes sub-disciplines become particularly hot topics and can occupy so much space in the literature that they almost seem like major branches in their own right. (Over the past 40 years or so philosophy of mind—which is, generally speaking, mainly a sub-discipline of metaphysics—has taken on this position within analytic philosophy, and has attracted so much attention that some suggest philosophy of mind as the paradigm for what contemporary analytic philosophers do).
Originally the term "philosophy" was applied to all intellectual endeavors. Aristotle studied what would now be called biology, meteorology, physics, and cosmology, alongside his metaphysics and ethics. Even in the eighteenth century physics and chemistry were still classified as "natural philosophy", that is, the philosophical study of nature. Today these latter subjects are popularly referred to as sciences, and as separate from philosophy. But the distinction is not clear; some philosophers still contend that science retains an unbroken — and unbreakable — link to philosophy.
More recently, psychology, economics, sociology, and linguistics were once the domain of philosophers insofar as they were studied at all, but now have only a weaker connection with the field. In the late twentieth century cognitive science and artificial intelligence could be seen as being forged in part out of "philosophy of mind."
Philosophy is done primarily through self-reflection and critical thinking. It does not tend to rely on experiment. However, in some ways philosophy is close to science in its character and method; some analytic philosophers have suggested that the method of philosophical analysis allows philosophers to emulate the methods of natural science; Quine holds that philosophy does no more than clarify the arguments and claims of other sciences. This suggests that philosophy might be the study of meaning and reasoning generally; but some still would claim either that this is not a science, or that if it is it ought not to be pursued by philosophers.
All these views have something in common: whatever philosophy essentially is or is concerned with, it tends on the whole to proceed more "abstractly" than most (or most other) natural sciences. It does not depend as much on experience and experiment, and does not contribute as directly to technology. It clearly would be a mistake to identify philosophy with any one natural science; whether it can be identified with science very broadly construed is still an open question.
This is an active discipline pursued by both trained philosophers and scientists. Philosophers often refer to, and interpret, experimental work of various kinds (as in philosophy of physics and philosophy of psychology), but such branches of philosophy aim at philosophical understanding of experimental work. Philosophers do not perform experiments and formulate scientific theories qua philosophers.
Like philosophy, most religious studies are not experimental. Parts of theology, including questions about the existence and nature of gods, clearly overlap with philosophy of religion. Aristotle considered theology a branch of metaphysics, the central field of philosophy, and most philosophers before the twentieth century have devoted significant effort to theological questions. So the two are not unrelated. But other parts of religious studies, such as the comparison of different world religions, can be easily distinguished from philosophy in just the way that any other social science can be distinguished from philosophy. These are closer to history and sociology, and involve specific observations of particular phenomena, here particular religious practices.
The empiricist tradition in modern philosophy often held that religious questions are beyond the scope of human knowledge, and many have claimed that religious language is literally meaningless: there are not even questions to be answered. Some philosophers have felt that these difficulties in evidence were irrelevant, and have argued for, against, or just about religious beliefs on moral or other grounds.
The philosophy of mathematics is a branch of philosophy of science; but in many ways mathematics has a special relationship to philosophy. This is because the study of logic is a central branch of philosophy, and mathematics is a paradigmatic example of logic. In the late nineteenth and twentieth centuries, logic made great advances, and mathematics has been proven to be reducible to logic (at least, to first-order logic with some set theory). The use of formal, mathematical logic in philosophy now resembles the use of mathematics in science, although it is not as frequent.
In analytic philosophy, anti-realism is an epistemological position first articulated by British philosopher Michael Dummett. The term was coined as an argument against a form of realism Dummett saw as 'colorless reductionism'.
In philosophy, empiricism is a theory that states that knowledge comes only or primarily from sensory experience. It is one of several views of epistemology, the study of human knowledge, along with rationalism and skepticism. Empiricism emphasises the role of empirical evidence in the formation of ideas, rather than innate ideas or traditions. However, empiricists may argue that traditions arise due to relations of previous sense experiences.
Metaphysics is the branch of philosophy that examines the fundamental nature of reality, including the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. The word "metaphysics" comes from two Greek words that, together, literally mean "after or behind or among [the study of] the natural". It has been suggested that the term might have been coined by a first century CE editor who assembled various small selections of Aristotle’s works into the treatise we now know by the name Metaphysics.
Analytic philosophy is a style of philosophy that became dominant in the Western world at the beginning of the 20th century. The term can refer to one of several things:
German philosophy, here taken to mean either (1) philosophy in the German language or (2) philosophy by Germans, has been extremely diverse, and central to both the analytic and continental traditions in philosophy for centuries, from Gottfried Wilhelm Leibniz through Immanuel Kant, Georg Wilhelm Friedrich Hegel, Arthur Schopenhauer, Karl Marx, Friedrich Nietzsche, Martin Heidegger and Ludwig Wittgenstein to contemporary philosophers. Søren Kierkegaard is frequently included in surveys of German philosophy due to his extensive engagement with German thinkers.
In the 19th century, the philosophies of the Enlightenment began to have a dramatic effect, the landmark works of philosophers such as Immanuel Kant and Jean-Jacques Rousseau influencing new generations of thinkers. In the late 18th century a movement known as Romanticism began; it validated strong emotion as an authentic not of aesthetic experience, placing new emphasis on such emotions as trepidation, horror and terror and awe. Key ideas that sparked changes in philosophy were the fast progress of science; evolution, as postulated by Vanini, Diderot, Lord Monboddo, Erasmus Darwin, Lamarck, Goethe, and Charles Darwin; and what might now be called emergent order, such as the free market of Adam Smith within nation states. Pressures for egalitarianism, and more rapid change culminated in a period of revolution and turbulence that would see philosophy change as well.
Pseudophilosophy is a philosophical idea or system which does not meet an expected set of standards.
17th century philosophy is generally regarded as seeing the start of modern philosophy, and the shaking off of the medieval approach, especially scholasticism. It succeeded the Renaissance and preceded the Age of Enlightenment. It is often considered to be part of early modern philosophy.
Continental philosophy is a set of 19th- and 20th-century philosophical traditions from mainland Europe. This sense of the term originated among English-speaking philosophers in the second half of the 20th century, who used it to refer to a range of thinkers and traditions outside the analytic movement. Continental philosophy includes German idealism, phenomenology, existentialism, hermeneutics, structuralism, post-structuralism, deconstruction, French feminism, psychoanalytic theory, and the critical theory of the Frankfurt School and related branches of Western Marxism.
Modern philosophy is philosophy developed in the modern era and associated with modernity. It is not a specific doctrine or school, although there are certain assumptions common to much of it, which helps to distinguish it from earlier philosophy.
20th-century philosophy saw the development of a number of new philosophical schools—including logical positivism, analytic philosophy, phenomenology, existentialism, and poststructuralism. In terms of the eras of philosophy, it is usually labelled as contemporary philosophy.
Contemporary philosophy is the present period in the history of Western philosophy beginning at the early 20th century with the increasing professionalization of the discipline and the rise of analytic and continental philosophy.
Absolute idealism is an ontologically monistic philosophy "chiefly associated with Friedrich Schelling and G. W. F. Hegel, both German idealist philosophers of the 19th century, Josiah Royce, an American philosopher, and others, but, in its essentials, the product of Hegel". It is Hegel's account of how being is ultimately comprehensible as an all-inclusive whole. Hegel asserted that in order for the thinking subject to be able to know its object at all, there must be in some sense an identity of thought and being. Otherwise, the subject would never have access to the object and we would have no certainty about any of our knowledge of the world. To account for the differences between thought and being, however, as well as the richness and diversity of each, the unity of thought and being cannot be expressed as the abstract identity "A=A". Absolute idealism is the attempt to demonstrate this unity using a new "speculative" philosophical method, which requires new concepts and rules of logic. According to Hegel, the absolute ground of being is essentially a dynamic, historical process of necessity that unfolds by itself in the form of increasingly complex forms of being and of consciousness, ultimately giving rise to all the diversity in the world and in the concepts with which we think and make sense of the world.
The history of philosophy in Poland parallels the evolution of philosophy in Europe in general.
