There is something mean in human nature that prefers to think evil, that gives a willing ear and a ready welcome to calumny, a sort of jealousy of goodness and greatness and things of good report.

Human nature is evil, and goodness is caused by intentional activity.

In each of us, two natures are at war – the good and the evil. All our lives the fight goes on between them, and one of them must conquer. But in our own hands lies the power to choose – what we want most to be we are.

I hope you haven't given up on the S.Q.'s of the world, Reynie. As you see, there are a great many sheep in wolves' clothing. If not for S.Q.'s good nature, we'd never have escaped.

Human nature is above all things lazy.

Everybody has good and bad forces working with them, against them, and within them.
