By which thing it seems to me to be sufficiently proved that the errors of the Gentiles in ethics, physics, and the mode of seeking truth, errors many and manifold, but conspicuously represented in these two schools of philosophy, continued even down to the Christian era, notwithstanding the fact that the learned assailed them most vehemently, and employed both remarkable skill and abundant labour in subverting them. Yet these errors we see in our time to have been already so completely silenced, that now in our schools of rhetoric the question what their opinions were is scarcely ever mentioned; and these controversies have been now so completely eradicated or suppressed in even the Greek gymnasia, notably fond of discussion, that whenever now any school of error lifts up its head against the truth, i.e. against the Church of Christ, it does not venture to leap into the arena except under the shield of the Christian name. Whence it is obvious that the Platonist school of philosophers felt it necessary, having changed those few things in their opinions which Christian teaching condemned, to submit with pious homage to Christ, the only King who is invincible, and to apprehend the Incarnate Word of God, at whose command the truth which they had even feared to publish was immediately believed.
