Foundationalism concerns philosophical theories of knowledge resting upon justified belief, some secure foundation of certainty.〔Simon Blackburn, ''The Oxford Dictionary of Philosophy'', 2nd (New York: Oxford University Press, 2005), (p 139 ).〕 Its main rivals are Fallibilism & coherentism whereby a body of knowledge, not requiring a secure foundation, can be established by the interlocking strength of its components, like a puzzle solved without prior certainty that each small region was solved correctly.〔 Identifying the other options to be either circular reasoning or infinite regress, thus the regress problem, Aristotle found the clear choice to be foundationalism, which posits basic beliefs underpinning others.〔Ted Poston, ("Foundationalism" ), ''Internet Encyclopedia of Philosophy'', 10 Jun 2010 (last updated).〕 Descartes, the most famed foundationalist, discovered a foundation in the fact of his own existence and the "clear and distinct" ideas of reason,〔〔 whereas Locke saw foundation in experience. A foundation reflects differing epistemological emphases—empiricists emphasizing ''experience'', rationalists emphasizing ''reason''—but may blend both.〔 In the 1930s, debate over foundationalism revived.〔 Whereas Schlick viewed scientific knowledge like a pyramid where a special class of statements does not require verification through other beliefs and serves as a foundation, Neurath argued that scientific knowledge lacks an ultimate foundation and acts like a raft.〔 In the 1950s, foundationalism fell into decline largely via Quine,〔 whose ontological relativity found any belief networked to one's beliefs on all of reality, while auxiliary beliefs somewhere in the vast network are readily modified to protect desired beliefs. Classically, foundationalism had posited infallibility of basic beliefs and deductive reasoning between beliefs—a strong foundationalism.〔 Since about 1975, weak foundationalism emerged.〔 Thus, recent foundationalists have variously allowed fallible basic beliefs, and inductive reasoning between them, either by enumerative induction or by inference to the best explanation.〔 And whereas internalists require cognitive access to justificatory means, externalists find justification without such access. ==Outline== Foundationalism is an attempt to respond to the regress problem of justification in epistemology. According to this argument, every proposition requires justification to support it, but any justification also needs to be justified itself. If this goes on ''ad infinitum'', it is not clear how anything in the chain could be justified. Foundationalism holds that there are 'basic beliefs' which serve as foundations to anchor the rest of our beliefs.〔O'Brien 2006, pp. 61-62〕 Strong versions of the theory assert that an indirectly justified belief is completely justified by basic beliefs; more moderate theories hold that indirectly justified beliefs require basic beliefs to be justified, but can be further justified by other factors.〔Audi 2003, p. 194〕 During thousands of years, Western philosophy pursued a solid foundation as the ultimate and eternal reference system of knowledge called foundationalism. It has existed since ancient Greece, the focus of this theory is that all knowledge or cognitive awareness of the subject (human being) are based on a solid foundation. This foundation serves not only as the starting point merely as a basis for knowledge of the truth of existence. Thinking is the process of proving the validity of knowledge, not proving the rationality of the foundation from which knowledge is shaped. This means, with ultimate cause, the foundation is true, absolute, entire and impossible to prove. Neo-Pragmatic philosopher Richard Rorty said that the fundamentalism confirmed the existence of the ''privileged representation''〔Rorty, Richard (1979). Philosophy and the mirror of nature. Princeton University Press. pp.165 – 173〕 which constitutes the foundation, from which dominates epistemology. Plato's theory of Forms is the earliest foundationalism. So from the point of view of Plato, the Forms shows the general concept which plays as a model for the release of existence, which is only the faint copy of the Forms of eternity, that means, understanding the expression of objects leads to acquiring all knowledge, then acquiring knowledge accompanies achieving the truth. Achieving the truth means understanding the foundation. This idea still has some appeal in for example international relations studies.〔Smith, Steve, Ownens Patrica, "Alternative approaches to international relations theory" in "The Globalisation of World Politics", Baylis, Smith and Owens, OUP, 4th ed, p177〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「foundationalism」の詳細全文を読む スポンサード リンク
