Why this word is great
ISAGOGE — [Noun] A scholarly introduction, particularly Porphyry’s systematic guide to Aristotle’s works. From the Latin īsagōgē, borrowed from Ancient Greek εἰσαγωγή (eisagōgḗ, "lead-in"), from εἰς (eis, "into") + ἀγωγή (agōgḗ, "to lead"). Unlike a "prolegomenon" (which dissects a text before it begins) or a "preface" (which offers personal or anecdotal context), an isagoge is a bridge—neither wholly detached nor casually intimate. It is the scholar’s lantern held at the threshold of a labyrinth, the careful arrangement of tools before surgery, the tuning of strings before the symphony—a quiet insistence that to enter rightly is to understand.
