The fear of the Lord tendeth to life: and he that hath it shall abide satisfied; he shall not be visited with evil.
The wise man avoids evil by anticipating it.
There can be no such thing as a necessary evil. For, if a thing is really necessary, it cannot be an evil and if it is an evil, it is not necessary.
There is only one way to put an end to evil, and that is to do good for evil.
Never let a man imagine that he can pursue a good end by evil means, without sinning against his own soul. The evil effect on himself is certain.
Combinations of wickedness would overwhelm the world, by the advantage which licentious principles afford, did not those who have long practised perfidy grow faithless to each other.
No man ever became very wicked all at once.
Whoever takes it upon himself to establish a commonwealth and prescribe laws must presuppose all men naturally bad, and that they will yield to their innate evil passions as often as they can do so with safety.
Real evils can be either cured or endured; it is only imaginary evils that make people anxiety-ridden for a lifetime.
A good end cannot sanctify evil means, nor must we ever do evil that good may come of it.
