The modern skeptical world has been taught for some 200 years a conception of human nature in which the reality of evil, so well-known to the age of faith, has been discounted.

We shall have to recover this forgotten but essential truth ‑ along with so many others that we lost when, thinking we were enlightened and advanced, we were merely shallow and blind.
