In a world which is armed to its teeth with nuclear weapons, every quarrel or difference of opinion may lead to violence of a kind quite different from what is possible today.

It is immoral from almost any point of view to refuse to defend yourself and others from very grave and terrible threats, even as there are limits to the means that can be used in such defense.

Authority is not power; that's coercion. Authority is not knowledge; that's persuasion, or seduction. Authority is simply that the author has the right to make a statement and to be heard.
