“let us say that P is inferentially justified if its justification is constituted by the having of at least one belief other than P. A belief is noninferentially justified if its justification does not consist in the having of any other belief” (pg. 56)
The foundationalist claims that every justified belief is grounded in some belief that is noninferentially justified, which both paradigm externalists and internalists hold. However, both the externalist and externalist hold different views of what is noninferential. In retrospect, an issue arises in relation to inferentially justification.
