The historic and philosophical roots of analytical philosophy are traced within the logical custom of Aristotle, the custom of British empiricism and nominalism, partly Kantian philosophy, in addition to Austrian philosophical considered the second half of the XIX century. The predecessors of analytical philosophy are R. Descartes, T. Hobbes, J. Locke, GW Leibniz, J. Berkeley, D. Hume, I. Kant, J. St. Mill, in addition to F. Brentano and his followers, who had been the primary theorists of “scientific” philosophy within the XIX century.
The preliminary issues and ideas of analytical philosophy had been formulated within the article of German logic and thinker G. Frege “On the That means and Significance”, revealed in 1892. It’s thought-about to be the start of an analytical philosophy, since on this article the primary issues are formulated and the fundamental ideas of analytical philosophy are launched. Frege examines the query of the distinction between the cognitive worth of artificial (as I. Kant known as them) judgments (A = B) from the cognitive worth of analytical judgments (A = A). The increment of information is achieved on the expense of the previous, however the causes for figuring out two completely different expressions A and B (the situation for the reality of the artificial judgment) are removed from clear. Frege assumed that the “correct names” (phrases, indicators, notations, expressions) coming into the artificial judgment are recognized after they level to the identical frequent referent (the coinciding exterior object to which they’re directed).
Among the many well-known philosophers and logicians of the late 19th and early 20th centuries G. Frege holds a particular place. His function in trendy logic, which he largely created, is comparable solely with the function of Aristotle within the logic of the standard. Frege, particularly, laid the foundations of the sector of information, which was known as the foundations of arithmetic, for the primary time clearly related the issue of formal unity of the content material of arithmetic with the strategies of reasoning adopted in it and thereby laid the foundations of the idea of formal techniques. This grew to become doable solely as a result of one of many first axiomatizations of the logic of propositions and the logic of predicates was carried out, and the latter really really first appeared in his writings. Frege laid the foundations of logical semantics, separating within the logical idea of the technique of expression (syntax) from what they designate. Lastly, he put ahead a program for clarifying the fundamental ideas of arithmetic, which he tried to implement with the assistance of the process of decreasing arithmetic to logic, realizing one of many doable strategies for clarifying the specifics of mathematical information. The totality of the outcomes achieved by him in logic presupposed a totally particular conceptual shift, which displays the affect of his writings on the event of recent thought as an entire.
Russell, demonstrating the contradictory views of the consultant of the college of absolute idealism FG Bradley, contrasts the logic of the “inner relations” of absolute idealism and philosophical monism with the logic of “exterior relations” and the picture of a pluralistic universe, corresponding, because it appeared, to the character of recent science and “life like “To the view. Criticism of Russell’s philosophical techniques of the previous was lowered to the truth that the standard “speculative philosophy” (or “metaphysics” in his terminology) gave an incorrect rationalization of the world resulting from using “dangerous grammar,” so a extra “analytical” language is required to translate the reality. Therefore, in his opinion, the necessity to transfer to the evaluation of sentences, based mostly on the logic of quantifiers created by G. Frege and J. Peano, follows. Russell outlined such an evaluation as a transition from one thing obscure, indefinite, inaccurate to clear, clear, particular ideas that make up the ultimate restrict of study and are on this sense the “atoms” of the language (therefore the identify of his idea – “logical atomism”). In his conception, the atoms of a logically excellent language should be in one-to-one correspondence with the information.
Together with this, JE Moore, who was engaged within the evaluation of philosophical ideas and issues via peculiar language and customary sense, developed conceptual approaches for procedures for rephrasing unclear statements in synonymous and clearer. In his first works, Moore condemns the thesis of “philosophy for philosophers,” that’s, criticizes the argumentation of conventional philosophy, above all, of idealism prevailing within the British universities of that point. The situation of comparability for assessing philosophical theses he thought-about frequent sense. Furthermore, in Moore’s evaluation, philosophy is not engaged within the logical structuring of the topic and its discount to the norms of language (as Russell does), however the topics of speech are “dismembered” by philosophical theses with the intention to cut back them to the best working theses, frontal and commensurate with frequent sense sense, oriented to the norms of empiricism. Moore’s Cambridge works, crucial of which is the article “The Nature of Judgment” (1899), have gained broad reputation for the reason that starting of the 20th century and shortly started to affect the formation of analytical rationality of the English kind.
