Simplicius on Tekmeriodic Proofs

► Plausibly the signs on which Simplicius bases his tekmeriodic proofs are refutable. ► Their epistemic worth lies in their being probative rather than valid. ► Simplicius conceives of the acquisition of the principles as inductive. ► Simplicius evaluates these proofs against Plato's un-hypothetical knowledge. ► In his view their use does not grant natural philosophy autonomy from metaphysics.
