 Hermeneutics opposes what can be described as the ‘vertical’ picture of knowledge at issue in epistemological foundationalism, focusing, instead, on the ‘circularity’ at issue in understanding. In epistemological foundationalism, our body of beliefs (or at least our justified beliefs) are sometimes said to have the structure of an edifice. Some beliefs are distinguished as foundations, ultimately, because they depend on no further beliefs for their justification; other beliefs are distinguished as founded, in that their justification depends on the foundational beliefs (Steup and Neta 2015, Section 4.1). This is a ‘vertical’ picture of human knowledge in that new beliefs build on established beliefs; new beliefs are justified on the basis of already justified beliefs, and these beliefs, in turn, are justified by still other beliefs, all the way down to the foundational beliefs. Inquiry, then, is an ‘upward’ pursuit, one that adds new ‘floors’ to the edifice of what we already know.
