Résumé/Abstract: The Logical Firmament

Most work in the epistemology of logic asks how inferential rules are known, and how individual steps in a proof are justified.  But what happens when single steps are composed into a complex derivation?  A new set of facts—“combinational facts”—come into play, which have been undertheorized despite being at the heart of such phenomena as logical non-omniscience.  I will ask how recognition of these facts might alter our epistemology of logic.  And I will make a tentative proposal for how combinational facts come to be known.
