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.

Pheochromocytoma

Pheochromocytoma is a rare tumor that usually starts in the cells of one of your adrenal glands. Although they are usually benign, pheochromocytomas often cause the adrenal gland to make too many hormones. This can lead to high blood pressure and cause symptoms such as

* Headaches
* Sweating
* Pounding of the heart
* Chest pain
* A feeling of anxiety

Sometimes pheochromocytoma is part of another condition called multiple endocrine neoplasia syndrome (MEN). People with MEN often have other cancers and other problems involving hormones.

Rehabilitation

After a serious injury, illness or surgery, you may recover slowly. You may need to regain your strength, relearn skills or find new ways of doing things you did before. This process is rehabilitation.

Rehabilitation often focuses on

* Physical therapy to help your strength, mobility and fitness
* Occupational therapy to help you with your daily activities
* Speech-language therapy to help with speaking, understanding, reading, writing and Swallowing
* Treatment of pain

Nineteenth century philosophy

Later modern philosophy is usually careful to begin after the philosophy of Immanuel Kant at the start of the 19th-century. German idealists, such as Fichte, Hegel, and Schelling, prolonged on the work of Kant by maintain that the world is constitute by a rational mind-like process, and as such is totally knowable.

Rejecting idealism, other philosophers, many working from outside the college, initiated lines of thought that would occupy academic attitude in the early and mid-20th century:

* Frege's work in logic and Sidgwick's work in ethics provide the tools for early analytic attitude

* Husserl initiates the school of phenomenology

* Peirce and William James initiated the school of practicality

* Kierkegaard and Nietzsche laid the foundation for existentialism

Early modern philosophy

Modern philosophy begins with the revival of cynicism and the rise of current physical science. Philosophy in this period centers on the relative between experience and actuality, the ultimate origin of information, the nature of the mind and it’s relative to the body, the implications of the new usual sciences for free will and God, and the appearance of a secular base for moral and political philosophy.

Canonical figures contain Montaigne, Bacon, Hobbes, Descartes, Locke, Spinoza, Leibniz, Berkeley, Hume, and Kant. Chronologically, this era spans the 17th and 18th centuries, and is usually careful to end with Kant's systematic effort to reconcile Newtonian physics with customary metaphysical topics.

Medieval philosophy

Medieval philosophy is the philosophy of Western Europe and the Middle East during what is now known as the medieval era or the Middle Ages, roughly extend from the fall of the Roman Empire to the Renaissance. Medieval philosophy is distinct partly by the rediscovery and further growth of classical Greek and Hellenistic philosophy, and partly by the need to address theological harms and to integrate sacred doctrine with secular learning.

Some problems discuss throughout this period are the relation of faith to reason, the continuation and unity of God, the object of theology and metaphysics, the problems of information, of universals, and of individuation.

Philosophers from the Middle Ages comprise the Muslim philosophers Alkindus, Alfarabi, Alhazen, Avicenna, Algazel, Avempace, Abubacer and Averroes; the Jewish philosophers Maimonides and Gersonides; plus the Christian philosopher Anselm, Peter Abelard, Roger Bacon, Thomas Aquinas, Duns Scotus, William of Ockham and Jean Buridan.

Ancient philosophy

Ancient philosophy is the philosophy of the Graeco-Roman globe from the sixth century B.C. to the fourth century A.D. It is typically divided into four periods: the pre-Socratic period, the periods of Plato and Aristotle, and the post-Aristotelian period. Sometimes a fifth period is additional that include the Christian and Neo-Platonist philosophers. The most significant of the ancient philosophers are Plato and Aristotle.

The themes of ancient philosophy are: sympathetic the basic causes and principles of the universe; explanation it in an economical and uniform way; the epistemological problem of reconciling the variety and change of the natural universe, with the possibility of obtain fixed and certain knowledge about it; question about things which cannot be perceived by the senses, such as numbers, elements, universals, and gods; the psychiatry of patterns of analysis and argument; the nature of the good life and the meaning of accepting and knowledge in order to pursue it; the explication of the concept of justice, and its relation to various political systems.

In this period the crucial skin of the philosophical method were recognized: a critical approach to received or recognized views, and the appeal to cause and argumentation.

Western philosophy

The opening of the terms "philosopher" and "philosophy" has been qualified to the Greek thinker Pythagoras. The ascription is base on a way in a lost work of Herakleides Pontikos, a follower of Aristotle. It is measured to be part of the widespread myths of Pythagoras of this time. "Philosopher" replaces the word "sophist”, which was used to explain "wise men," teachers of rhetoric, who were significant in Athenian democratic system.

The history of philosophy is normally divided into three periods: Ancient philosophy, medieval philosophy, and Modern philosophy.

Branches of philosophy

To give a thorough list of the main branches of philosophy is difficult, because there have been dissimilar, equally acceptable divisions at different times, and the division are often relative to the concern of a particular period. However, the following branches are usually established as the main ones.

* Metaphysics investigate the nature of being and the world. Usual branches are cosmology and ontology.

* Epistemology is concerned with the nature and scope of awareness, and whether knowledge is achievable. Among its central concern has been the challenge posed by skepticism and the relationships among truth, belief and justification.

* Ethics, or 'moral philosophy', is concerned with questions of how persons ought to act or if such question are answerable. The major branches of ethics are meta-ethics, normative ethics and applied ethics.

* Political Philosophy is the study of government and the association of individuals and communities to the state. It includes question about law, property, and the rights and obligation of the citizen.

* Aesthetics deal with beauty, art, enjoyment, sensory-emotional values, perception, and matters of taste and response.

* Logic deals with pattern of thinking that lead from true premises to true conclusion. Beginning in the late 19th century, mathematicians such as Frege began a mathematical action of logic, and today the subject of logic has two broad divisions are mathematical logic and what is now called philosophical logic.

* Philosophy of Mind deals with the natural world of the mind and its relationship to the body, and is typified by disputes among dualism and materialism. In recent years there is an increasing link between this branch of philosophy and cognitive discipline

* Philosophy of language is the reasoned query into the nature, origins, and usage of language.

Most studious subject has a philosophy, for example the philosophy of science, the philosophy of mathematics, and the philosophy of history. In addition, a range of academic subject has emerged to deal with areas which would have in history been the subject of philosophy. These comprise Psychology, Anthropology and Science.

Philosophy

Philosophy is the study of common and fundamental troubles regarding matters such as continuation, knowledge, truth, justice, beauty, validity, mind, and language. Philosophy is renowned from other ways of address these questions by its critical, usually systematic advance and its reliance on consistent argument. The word philosophy born from Ancient Greek origin its meaning "love of knowledge", "love of wisdom".
