This distinction is perhaps the most important that was ever drawn in philosophy. And, therefore, the history of the various fortunes which it has undergone, and of the controversies and perplexities which have arisen from confounding it, cannot be out of place in a work which professes to furnish the text of all metaphysical annotation. This, too, is the proposition under which the discussion referred to appropriately falls.
Aim and procedure of Greek metaphysics.9. It has been stated elsewhere (Prop. IV., Obs. 20), that the aim of the early Greek metaphysic, in so far as it was of an epistemological character, was the explanation of the conversion of the unintelligible into the intelligible—of the process through which the unknowable passed into the knowable—of the change which the not-to-be-understood had to undergo in becoming the to-be-understood.
