David Roochnik (born 1951) is an American philosopher and the Maria Stata professor of philosophy at Boston University. [1]
Prior to completing his doctorate degree at Pennsylvania State University in 1995, Professor Roochnik taught at Iowa State University and Williams College. He joined the philosophy department at Boston University in 1995.
In his 1991 book, The Tragedy of Reason, Professor Roochnik presents an interpretation of the historical evolution of reason, or logos , as an ongoing quarrel. One camp, represented by Cleitophon, is impatient with reason's failure to culminate in a teachable techne . A second camp, represented by Socrates, insists on protrepticizing young minds to know and care for themselves despite the lack of a clearly articulated techne of self-knowledge and self-care. Descartes, argues Roochnik, is a modern representative of Cleitophon's position. Admiring the certainty achieved by the techne of mathematics, and hoping to place all knowledge on this same firm footing, Descartes places everything he can't establish with mathematical certainty into doubt. To order his life while he pursues his project, however, Descartes must adopt what he calls a "provisional morality," in which he obeys all the laws and customs of his local society. Descartes, says Roochnik, tries to make logos into a techne and, finding that techne is insufficient to order his life, "fills the void created by the absence of logos with his provisional morality." [2] The hyper-rational realm of mathematical certainty has, as its "flipside," a realm of credulous and unquestioning acceptance of the laws and customs of society.
Epistemology, or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics.
Plato was an ancient Greek philosopher born in Athens during the Classical period in Ancient Greece. In Athens, Plato founded the Academy, a philosophical school where he taught the philosophical doctrines that would later became known as Platonism. Plato was a pen name derived from his nickname given to him by his wrestling coach – allegedly a reference to his physical broadness. According to Alexander of Miletus quoted by Diogenes of Sinope his actual name was Aristocles, son of Ariston, of the deme Collytus.
The problem of universals is an ancient question from metaphysics that has inspired a range of philosophical topics and disputes: Should the properties an object has in common with other objects, such as color and shape, be considered to exist beyond those objects? And if a property exists separately from objects, what is the nature of that existence?
Reason is the capacity of consciously applying logic by drawing conclusions from new or existing information, with the aim of seeking the truth. It is closely associated with such characteristically human activities as philosophy, science, language, mathematics, and art, and is normally considered to be a distinguishing ability possessed by humans. Reason is sometimes referred to as rationality.
In philosophy, rationalism is the epistemological view that "regards reason as the chief source and test of knowledge" or "any view appealing to reason as a source of knowledge or justification". More formally, rationalism is defined as a methodology or a theory "in which the criterion of truth is not sensory but intellectual and deductive".
Eudaimonia, sometimes anglicized as eudaemonia or eudemonia, is a Greek word literally translating to the state or condition of 'good spirit', and which is commonly translated as 'happiness' or 'welfare'.
Logos is a term used in Western philosophy, psychology and rhetoric and refers to the appeal to reason that relies on logic or reason, inductive and deductive reasoning. Aristotle first systemised the usage of the word, making it one of the three principles of rhetoric. This specific use identifies the word closely to the structure and content of text itself. This specific usage has then been developed through the history of western philosophy and rhetoric.
Phronesis, is a type of wisdom or intelligence relevant to practical action in particular situations. It implies both good judgment and excellence of character and habits, and was a common topic of discussion in ancient Greek philosophy. Classical works about this topic are still influential today. In Aristotelian ethics, the concept was distinguished from other words for wisdom and intellectual virtues – such as episteme and sophia – because of its practical character. The traditional Latin translation is prudentia, which is the source of the English word "prudence". Among other proposals, Thomas McEvilley has proposed that the best translation is "mindfulness".
Platonism is the philosophy of Plato and philosophical systems closely derived from it, though contemporary platonists do not necessarily accept all doctrines of Plato. Platonism had a profound effect on Western thought. In its most basic fundamentals, platonism affirms the existence of abstract objects, which are asserted to exist in a third realm distinct from both the sensible external world and from the internal world of consciousness, and is the opposite of nominalism. This can apply to properties, types, propositions, meanings, numbers, sets, truth values, and so on. Philosophers who affirm the existence of abstract objects are sometimes called platonists; those who deny their existence are sometimes called nominalists. The terms "platonism" and "nominalism" also have established senses in the history of philosophy. They denote positions that have little to do with the modern notion of an abstract object.
The Academy was founded by Plato in c. 387 BC in Athens. Aristotle studied there for twenty years before founding his own school, the Lyceum. The Academy persisted throughout the Hellenistic period as a skeptical school, until coming to an end after the death of Philo of Larissa in 83 BC. The Platonic Academy was destroyed by the Roman dictator Sulla in 86 BC.
Nous, or Greek νοῦς, sometimes equated to intellect or intelligence, is a concept from classical philosophy for the faculty of the human mind necessary for understanding what is true or real.
The Clitophon is a 4th-century BC dialogue traditionally ascribed to Plato, though the work's authenticity is debated. It is the shortest dialogue in Plato's traditional corpus. It centers on a discussion between Clitophon and Socrates, with Socrates remaining mostly silent. Most scholarship until recently has been concerned with the authenticity rather than the actual meaning and contents of Clitophon.
Diairesis is a form of classification used in ancient logic that serves to systematize concepts and come to definitions. When defining a concept using diairesis, one starts with a broad concept, then divides this into two or more specific sub-concepts, and this procedure is repeated until a definition of the desired concept is reached. Aristotle makes extensive use of diaresis in categorization as basis for syllogizing. He makes clear, however, that definition by diaresis does not in itself prove anything. Apart from this definition, the procedure also results in a taxonomy of other concepts, ordered according to a general–specific relation.
In psychology, the psyche is the totality of the human mind, conscious and unconscious. Many thinkers, including Carl Jung, also include in this definition the overlap and tension between the personal and the collective elements in man.
John Sallis is an American philosopher well known for his work in the tradition of phenomenology. Since 2005, he has been the Frederick J. Adelmann Professor of Philosophy at Boston College. He has previously taught at Pennsylvania State University (1996–2005), Vanderbilt University (1990–1995), Loyola University of Chicago (1983–1990), Duquesne University (1966–1983) and the University of the South (1964–1966).
The following outline is provided as an overview of and topical guide to metaphysics:
Substantial form is a central philosophical concept in Aristotelianism and, afterwards, in Scholasticism. The form is the idea, existent or embodied in a being, that completes or actualizes the potentiality latent in the matter composing the being itself. For Aristotle, in fact, matter is the basis of all that exists; it comprises the potentiality of everything, but of itself is not actually anything. A determinate thing only comes into being when the potentiality in matter is converted into actuality; this is achieved by the substantial form. It is substantial because it is the principle by which a material kind of thing is recognised as such.
Common sense is sound, practical judgment concerning everyday matters, or a basic ability to perceive, understand, and judge in a manner that is shared by nearly all people.
Neoplatonism is a strand of Platonic philosophy that emerged in the 3rd century AD against the background of Hellenistic philosophy and religion. The term does not encapsulate a set of ideas as much as a series of thinkers. Among the common ideas it does maintain is that of monism, the doctrine that all of reality can be derived from a single principle, "the One".
Charles H. Kahn was a classicist and professor emeritus of philosophy at the University of Pennsylvania. His work focused on early Greek philosophy, up to the times of Plato. His 1960 monograph on Anaximander was still as of 2020 the most important reference work on the subject, and his 1979 edition of the Heraclitus fragments likewise remained the most widely cited English translation of Heraclitus, more or less representing the 'standard interpretation' for non-expert scholars.
