 Foundationalists reject (1). They take some propositions to be self-evident or they permit beliefs to be justified by non-beliefs (such as perceptions or intuitions). Coherentists reject (2). They tolerate some forms of circular reasoning. For instance, Nelson Goodman (1965) has characterized the method of reflective equilibrium as virtuously circular. Charles Saunders Peirce (1933–35, 5.250) may have rejected (3). The first clear rejector is Peter Klein (2007). For a book-length defense, read Scott F. Aikin (2011). Infinitists believe that infinitely long chains of justification are no more impossible than infinitely long chains of causation. Finally, the epistemological anarchist rejects (4). As Paul Feyerabend refrains in Against Method, “Anything goes” (1988, vii, 5, 14, 19, 159).
