Tertullian

It is a comparatively small thing, that certain men, like Phygellus, and Hermogenes, and Philetus, and Hymenµus, deserted His apostle: the betrayer of Christ was himself one of the apostles.

Unhappy Aristotle! who invented for these men dialectics, the art of building up and pulling down; an art so evasive in its propositions, so far-fetched in its conjectures, so harsh, in its arguments, so productive of contentions-embarrassing even to itself, retracting everything, and really treating of nothing! Whence spring those "fables and endless genealogies," and "unprofitable questions," and "words which spread like a cancer? " From all these, when the apostle would restrain us, he expressly names philosophy as that which he would have us be on our guard against.
