 The difficulties pertaining to both rationalism and empiricism about justification have led many epistemologists to think that there must be something fundamentally wrong with the way in which the debate has been framed, prompting their rejection of the foundationalist justificatory structure underlying rationalism and empiricism alike. Rather than conceiving the structure of our knowledge on the model of Euclidean geometry, with its basic axioms and derived theorems, these epistemologists favor a holistic picture of justification which does not distinguish between basic or foundational and non-basic or derived beliefs, treating rather all our beliefs as equal members of a “web of belief” (Quine and Ullian 1970, cf. Neurath 1983/1932 and Sosa 1980).
