Existentialism is a family of philosophical views and inquiry that prioritize the existence of the human individual, study existence from the individual's perspective, and conclude that, despite the absurdity or incomprehensibility of the universe, individuals must still embrace responsibility for their actions and strive to lead authentic lives. In examining meaning, purpose, and value, existentialist thought often includes concepts such as existential crises, angst, courage, and freedom.
Georg Wilhelm Friedrich Hegel was a German philosopher and one of the most influential figures of German idealism and 19th-century philosophy. His influence extends across the entire range of contemporary philosophical topics, from metaphysical issues in epistemology and ontology, to political philosophy, the philosophy of history, philosophy of art, philosophy of religion, and the history of philosophy.
Idealism in philosophy, also known as philosophical idealism or metaphysical idealism, is the set of metaphysical perspectives asserting that, most fundamentally, reality is equivalent to mind, spirit, or consciousness; that reality is entirely a mental construct; or that ideas are the highest type of reality or have the greatest claim to being considered "real". Because there are different types of idealism, it is difficult to define the term uniformly.
Truth or verity is the property of being in accord with fact or reality. In everyday language, it is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.
The distinction between subject and object is a basic idea of philosophy.
Phenomenology is a philosophical study and movement largely associated with the early 20th century that seeks to objectively investigate the nature of subjective, conscious experience. It attempts to describe the universal features of consciousness while avoiding assumptions about the external world, aiming to describe phenomena as they appear to the subject, and to explore the meaning and significance of the lived experiences.
Solipsism is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind.
George Santayana was a Spanish-American philosopher, essayist, poet, and novelist. Born in Spain, Santayana was raised and educated in the United States from the age of eight and identified as an American, yet always retained a valid Spanish passport. At the age of 48, he left his academic position at Harvard University and permanently returned to Europe; his last will was to be buried in the Spanish Pantheon in the Campo di Verano, Rome.
Being and Nothingness: An Essay on Phenomenological Ontology, sometimes published with the subtitle A Phenomenological Essay on Ontology, is a 1943 book by the philosopher Jean-Paul Sartre. In the book, Sartre develops a philosophical account in support of his existentialism, dealing with topics such as consciousness, perception, social philosophy, self-deception, the existence of "nothingness", psychoanalysis, and the question of free will.
German idealism is a philosophical movement that emerged in Germany in the late 18th and early 19th centuries. It developed out of the work of Immanuel Kant in the 1780s and 1790s, and was closely linked both with Romanticism and the revolutionary politics of the Enlightenment. The period of German idealism after Kant is also known as post-Kantian idealism or simply post-Kantianism. One scheme divides German idealists into transcendental idealists, associated with Kant and Fichte, and absolute idealists, associated with Schelling and Hegel.
Absurdism is the philosophical theory that the universe is irrational and meaningless. It states that trying to find meaning leads people into conflict with a seemingly meaningless world. This conflict can be between rational man and an irrational universe, between intention and outcome, or between subjective assessment and objective worth, but the precise definition of the term is disputed. Absurdism claims that, due to one or more of these conflicts, existence as a whole is absurd. It differs in this regard from the less global thesis that some particular situations, persons, or phases in life are absurd.
Fideism is a standpoint or an epistemological theory which maintains that faith is independent of reason, or that reason and faith are hostile to each other and faith is superior at arriving at particular truths. The word fideism comes from fides, the Latin word for faith, and literally means "faith-ism". Philosophers have identified a number of different forms of fideism. Strict fideists hold that reason has no place in discovering theological truths, while moderate fideists hold that though some truth can be known by reason, faith stands above reason.
In existentialism, bad faith is the psychological phenomenon whereby individuals act inauthentically, by yielding to the external pressures of society to adopt false values and disown their innate freedom as sentient human beings. Bad faith also derives from the related concepts of self-deception and ressentiment.
Aleksey Stepanovich Khomyakov was a Russian theologian, philosopher, poet and amateur artist. He co-founded the Slavophile movement along with Ivan Kireyevsky, and he became one of its most distinguished theoreticians. His son Nikolay Khomyakov was a speaker of the State Duma.
"The Will to Believe" is a lecture by William James, first published in 1896, which defends, in certain cases, the adoption of a belief without prior evidence of its truth. In particular, James is concerned in this lecture about defending the rationality of religious faith even lacking sufficient evidence of religious truth. James states in his introduction: "I have brought with me tonight ... an essay in justification of faith, a defense of our right to adopt a believing attitude in religious matters, in spite of the fact that our merely logical intellect may not have been coerced. 'The Will to Believe,' accordingly, is the title of my paper."
The Life of Reason: The Phases of Human Progress is a book published in five volumes from 1905 to 1906, by Spanish-born American philosopher George Santayana. It consists of Reason in Common Sense, Reason in Society, Reason in Religion, Reason in Art, and Reason in Science.
Scepticism and Animal Faith (1923) is a later work by Spanish-born American philosopher George Santayana. He intended it to be "merely the introduction to a new system of philosophy," a work that would later be called The Realms of Being, which constitutes the bulk of his philosophy, along with The Life of Reason.
American philosophy is the activity, corpus, and tradition of philosophers affiliated with the United States. The Internet Encyclopedia of Philosophy notes that while it lacks a "core of defining features, American Philosophy can nevertheless be seen as both reflecting and shaping collective American identity over the history of the nation". The philosophy of the Founding Fathers of the United States is largely seen as an extension of the European Enlightenment. A small number of philosophies are known as American in origin, namely pragmatism and transcendentalism, with their most prominent proponents being the philosophers William James and Ralph Waldo Emerson respectively.
Romantic epistemology emerged from the Romantic challenge to both the static, materialist views of the Enlightenment (Hobbes) and the contrary idealist stream (Hume) when it came to studying life. Romanticism needed to develop a new theory of knowledge that went beyond the method of inertial science, derived from the study of inert nature, to encompass vital nature. Samuel Taylor Coleridge was at the core of the development of the new approach, both in terms of art and the 'science of knowledge' itself (epistemology). Coleridge's ideas regarding the philosophy of science involved Romantic science in general, but Romantic medicine in particular, as it was essentially a philosophy of the science(s) of life.
Marxist philosophy or Marxist theory are works in philosophy that are strongly influenced by Karl Marx's materialist approach to theory, or works written by Marxists. Marxist philosophy may be broadly divided into Western Marxism, which drew from various sources, and the official philosophy in the Soviet Union, which enforced a rigid reading of what Marx called dialectical materialism, in particular during the 1930s. Marxist philosophy is not a strictly defined sub-field of philosophy, because the diverse influence of Marxist theory has extended into fields as varied as aesthetics, ethics, ontology, epistemology, social philosophy, political philosophy, the philosophy of science, and the philosophy of history. The key characteristics of Marxism in philosophy are its materialism and its commitment to political practice as the end goal of all thought. The theory is also about the struggles of the proletariat and their reprimand of the bourgeoisie.
