Foundationalism

Classical foundationalism considers empirical evidence (sensory data) and self-evident axioms (math and logic, for example) to be properly basic. Modern foundationalism, denies that sensory data is properly basic, as our senses can be unreliable, and accepts only self-evident axioms and beliefs which are incorrigible (unable to be proven wrong). Reformed epistemology attempts to build a bridge between these beliefs, asserting that sensory data, memory and faith in God are properly basic.
