Factual relativism

Factual relativism (also called epistemic relativism, epistemological relativism, alethic relativism, and cognitive relativism) argues that truth is relative. According to factual relativism, facts used to justify claims are understood to be relative and subjective to the perspective of those proving or falsifying the proposition.^[1]

This form of relativism has its own particular problem, what Maurice Mandelbaum in 1962 termed the "self-excepting fallacy." Largely because of the self-excepting fallacy, few authors in the philosophy of science accept alethic cognitive relativism.^[2]
