Western Philosophy
Western philosophy refers to the Philosophy, philosophical thought, traditions and works of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with the ancient Greek philosophy of the Pre-Socratic philosophy, pre-Socratics. The word ''philosophy'' itself originated from the Ancient Greek (φιλοσοφία), literally, "the love of wisdom" , "to love" and σοφία ''Sophia (wisdom), sophía'', "wisdom". History Ancient The scope of ancient Western philosophy 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). Pre-Socratics The pre-Socratic philosophers were interested in cosmology (the nature and origin of the universe), while rejecting unargued fables in place for argued theory, i.e., dogma superseded reason, ...

Gymnasium (school)
''Gymnasium'' (and Gymnasium (school)#By country, variations of the word) is a term in various European languages for a secondary school that prepares students for higher education at a university.

Materialism And Empirio-criticism
''Materialism and Empirio-criticism'' (Russian: Материализм и эмпириокритицизм, ''Materializm i empiriokrititsizm'') is a philosophical work by Vladimir Lenin, published in 1909. It was an obligatory subject of study in all institutions of higher education in the Soviet Union, as a seminal work of dialectical materialism, a part of the curriculum called " Marxist–Leninist Philosophy". Lenin argued that human minds are capable of forming representations of the world that portray the world as it is. Thus, Lenin argues, our beliefs about the world can be objectively true; a belief is true when it accurately reflects the facts. According to Lenin, absolute truth is possible, but our theories are often only relatively true. Scientific theories can therefore constitute knowledge of the world. Lenin formulates the fundamental philosophical contradiction between idealism and materialism as follows: "Materialism is the recognition of 'objects in themselves' o ...

George Berkeley
George Berkeley ( ; 12 March 168514 January 1753), known as Bishop Berkeley (Bishop of Cloyne of the Anglican Church of Ireland), was an Anglo-Irish philosopher, writer, and clergyman who is regarded as the founder of "immaterialism", a philosophical theory he developed which was later referred to as "subjective idealism" by others. As a leading figure in the empiricism movement, he was one of the most cited philosophers of Age of Enlightenment, 18th-century Europe, and his works had a profound influence on the views of other thinkers, especially Immanuel Kant and David Hume. Interest in his ideas increased significantly in the United States during the early 19th century, and as a result, the University of California, Berkeley, as well as the city of Berkeley, California, were both named after him. In 1709, Berkeley published his first major work ''s:An Essay Towards a New Theory of Vision, An Essay Towards a New Theory of Vision'', in which he discussed the limitations of huma ...

Protagoras
Protagoras ( ; ; )Guthrie, p. 262–263. was a pre-Socratic Greek philosopher and rhetorical theorist. He is numbered as one of the sophists by Plato. In his dialogue '' Protagoras'', Plato credits him with inventing the role of the professional sophist. Protagoras is also believed to have created a major controversy during ancient times through his statement that "Of all things the measure is Man, of the things that are, that they are, and of the things that are not, that they are not" which was usually rendered simply as "Man is the measure of all things," interpreted (possibly wrongly, since he disagreed) by Plato to mean that there is no objective truth; Protagoras seems to have meant that each person's own personal history, experiences and expectations, developed over their lifetime, determine their judgments, opinions, and statements regarding "truth" (which is the title of the book in which Protagoras made this statement). When a person makes a judgment about a certain thin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Avenarius
Richard Ludwig Heinrich Avenarius (born Richard Habermann; 19 November 1843 – 18 August 1896) was a French-born German-Swiss philosopher. He formulated the radical positivist doctrine of "empirical criticism" or empirio-criticism. Life Avenarius attended the Nicolaischule in Leipzig and studied at the University of Zurich, Berlin, and the University of Leipzig. At the University of Leipzig, he received the Doctor of Philosophy in 1868 with his thesis on Baruch Spinoza and his pantheism, obtained the habilitation in 1876, and taught there as ''Privatdozent''. One year later, he became a professor at the University of Zurich. He died in Zurich in 1896. Work Avenarius believed that scientific philosophy must be concerned with purely descriptive definitions of experience, which must be free of both metaphysics and materialism.

Ernst Mach
Ernst Waldfried Josef Wenzel Mach ( ; ; 18 February 1838 – 19 February 1916) was an Austrian physicist and philosopher, who contributed to the understanding of the physics of shock waves. The ratio of the speed of a flow or object to that of sound is named the Mach number in his honour. As a philosopher of science, he was a major influence on logical positivism and American pragmatism. Through his criticism of Isaac Newton's theories of space and time, he foreshadowed Albert Einstein's theory of relativity. Biography Early life Mach was born in Chrlice (), Moravia, Austrian Empire (now part of Brno in the Czech Republic). His father Jan Nepomuk Mach, who had graduated from Charles-Ferdinand University in Prague, acted as tutor to the noble Brethon family in Zlín in eastern Moravia.

Phenomenalism
In metaphysics, phenomenalism is the view that physical objects cannot justifiably be said to exist as " things-in-themselves", but only as perceptual phenomena or sensory stimuli (e.g. redness, hardness, softness, sweetness, etc.) situated in time and in space. In particular, some forms of phenomenalism reduce all talk about physical objects in the external world to talk about ''bundles of sense data''. History Phenomenalism is a radical form of empiricism. Its roots as an ontological view of the nature of existence can be traced back to George Berkeley and his subjective idealism, upon which David Hume further elaborated. John Stuart Mill had a theory of perception which is commonly referred to as classical phenomenalism. This differs from Berkeley's idealism in its account of how objects continue to exist when no one is perceiving them. Berkeley claimed that an omniscient God perceived all objects and that this was what kept them in existence, whereas Mill claimed that perma ...
