Fear is an emotion indispensable for survival.

Evil thrives on apathy and cannot exist without it.

Goodness that comes out of hiding and assumes a public role is no longer good, but corrupt in its own terms and will carry its own corruption wherever it goes.

It is in the very nature of things human that every act that has once made its appearance and has been recorded in the history of mankind stays with mankind as a potentiality long after its actuality has become a thing of the past.

The most striking difference between ancient and modern sophists is that the ancients were satisfied with a passing victory of argument at the expense of truth, whereas the moderns want a more lasting victory at the expense of reality.

When evil is allowed to compete with good, evil has an emotional populist appeal that wins out unless good men and women stand as a vanguard against abuse.

It interrupts any doing, any ordinary activities, no matter what they happen to be. All thinking demands a stop-and-think.
