20th century philosophy

The 20th century brought with it upheavals that produced a series of conflicting developments within philosophy over the basis of knowledge and the validity of various absolutes. With classical certainties thought to be overthrown, and new social, economic, scientific, ethical, and logical problems, 20th-century philosophy was set for a series of attempts variously to reform, preserve, alter, abolish, previously conceived limits.

New studies in philosophy of science, philosophy of mathematics, and epistemology furthered seemingly antagonistic tendencies in accounting for consciousness and its objects, as expressed in the profound differences between analytic and continental philosophy, both of which had foundations in place at the beginning of the century. Advances in relativity, quantum, and nuclear physics, generative sciences like cognitive science, cybernetics, genetics, and generative linguistics, rich literary output, and the emergence of the motion picture as an art form greatly enriched philosophical subject matter.

Postanalytic philosophy

Postanalytic philosophy describes a detachment from the mainstream philosophical movement of analytic philosophy, which is the predominant school of thought in English-speaking countries. Postanalytic philosophy derives mainly from contemporary American thought, especially from the works of philosophers Richard Rorty, Donald Davidson, Hilary Putnam, and W.V. Quine. The term is closely associated with the much broader movement of contemporary American pragmatism, which, loosely defined, advocates a detachment from objective truth with an emphasis on convention, usefulness, and social progress.

The term postanalytic philosophy itself has been used in a vaguely descriptive sense and not in the sense of a concrete philosophical movement. Many postanalytic philosophers write along an analytic vein and on traditionally analytic topics. In an interview conducted by Wayne Hudson and Win van Reijen, Richard Rorty declared that, "I think that analytic philosophy can keep its highly professional methods, the insistence on detail and mechanics, and just drop its transcendental project. I'm not out to criticize analytic philosophy as a style. It's a good style. I think the years of superprofessionalism were beneficial."

Analytic philosophy

Analytic philosophy (sometimes, analytical philosophy) is a generic term for a style of philosophy that came to dominate English-speaking countries in the 20th century. In the United States, United Kingdom, Canada, Scandinavia, Australia, and New Zea land the overwhelming majority of university philosophy departments identify themselves as "analytic" departments.

* The positivist view that there are no specifically philosophical truths and that the object of philosophy is the logical clarification of thoughts. (This may be contrasted with the traditional found ationalism, deriving from Aristotle that views philosophy as a special sort of science, the highest one, which investigates the fundamental reasons and principles of everything. As a result, many analytic philosophers have considered their inquiries as continuous with, or subordinate to, those of the natural sciences.)

* The view that the logical clarification of thoughts can only be achieved by analysis of the logical form of philosophical propositions. (The logical form of a proposition is a way of representing it (often using the formal grammar and symbolism of a logical system) to display its similarity with all other propositions of the same type. However, analytic philosophers disagree widely about the correct logical form of ordinary language.)

Contemporary philosophy

Within the last century, philosophy has increasingly become an activity practiced within the university, and accordingly it has grown more specialized and more distinct from the natural sciences. Much of philosophy in this period concerns itself with explaining the relation between the theories of the natural sciences and the ideas of the humanities or common sense.

In the Anglophone world, analytic philosophy became the dominant school. In the first half of the century, it was a cohesive school, more or less identical to logical positivism, united by the notion that philosophical problems could and should be solved by attention to logic and language. In the latter half of the twentieth century, analytic philosophy diffused into a wide variety of disparate philosophical views, only loosely united by historical lines of influence and a self-identified commitment to clarity and rigor. Since roughly 1960, analytic philosophy has shown a revival of interest in the history of philosophy, as well as attempts to integrate philosophical work with scientific results, especially in psychology and cognitive science.

On continental Europe, no single school or temperament enjoyed dominance. The flight of the logical positivists from central Europe during the 1930s and 1940s, however, diminished philosophical interest in natural science, and an emphasis on the humanities, broadly construed, figures prominently in what is usually called "continental philosophy". Twentieth century movements such as phenomenology, existentialism, hermeneutics, structuralism, and post structuralism are included within this loose category.
