Foundationalism




Hence, generally, a foundationalist might offer the following Theory Of Justification :

:A belief is ''epistemically justified'' If And Only If (1) it is justified by a basic belief or beliefs, or (2) it is justified by a chain of beliefs that is supported by a basic belief or beliefs, and on which all the others are ultimately based.

A basic belief, on the other hand, does not require justification because it is a different kind of belief than a non-foundational one.


ARGUMENTS FOR FOUNDATIONALISM


Foundationalists most generally tend to argue that there must be some set of epistemologically basic propositions or else the process of justification will always lead to Agrippa's Trilemma , which ends in either an infinite regress, a dogmatic stopping point, or a circular argument, none of which are logically valid.


HISTORICAL FOUNDATIONALISM: RATIONALISM VS. EMPIRICISM


Historically, two varieties of foundationalist theories were Rationalism and Empiricism (or British Empiricism ). Strictly speaking, neither empiricism nor rationalism is necessarily committed to foundationalism (it is possible to be an empiricist Coherentist , for example, and that was a common epistemological position in 20th Century philosophy).

Rationalism is the general name for epistemological theories that maintain that reason is the source and criterion of knowledge. Rationalists generally hold that so-called truths of reason are the (most important) epistemologically basic propositions. The historical, continental Rationalism expounded by René Descartes is often regarded as antithetical to empiricism, while some contemporary rationalism asserts that reason is strongest when it is supported by or consistent with empirical evidence and hence relies heavily on empirical Science in analyzing justifications for belief. René Descartes famously held that some of these truths are known innately and therefore constitute basic innate knowledge, a view not always held in contemporary rationalism.

Empiricism is the general name for epistemological theories that maintain that sensation reports are the source and criterion of knowledge. Classical empiricists generally held that such reports are indubitable and incorrigible and therefore worthy of serving as epistemologically basic propositions.


ALTERNATIVES TO FOUNDATIONALISM


Alternatives to foundationalism, usually called Anti-foundationalism , include Coherentism , Reformed Epistemology and Reliabilism (though this has sometimes been construed as an unusual variant of foundationalism). Contextualism (or, in a stripped-down version, the Blind Posits Theory ) is the epistemological version of Relativism ; relativism is more often regarded as a theory of truth than as a theory of justification or knowledge. Also see Pragmatism .
