A lunatic is just a minority of one.

Perhaps a lunatic was simply a minority of one. At one time it had been a sign of madness to believe that the Earth goes round the Sun; today, to believe the past is inalterable. He might be alone in holding that belief, and if alone, then a lunatic. But the thought of being a lunatic did not greatly trouble him; the horror was that he might also be wrong.

We realize we can't go around saying and doing what we're actually thinking and feeling. If we all did that, life would be a lunatic asylum. Indeed, that's how you know you're talking to a lunatic. Lunatics are those poor souls who have lost their inner communication and so they allow themselves to say and do exactly what they are thinking and feeling and that's why they're mad.

Lunatics have no age. If we were crazy, you and I, we might be a great deal younger.

The lunatic is all idée fixe, and whatever he comes across confirms his lunacy. You can tell him by the liberties he takes with common sense, by his flashes of inspiration, and by the fact that sooner or later he brings up the Templars.

The difference between a humanist and a lunatic is in fact one of degree

The people who are regarded as moral luminaries are those who forego ordinary pleasures themselves and find compensation in interfering with the pleasures of others.

There are four kinds of people in this world: cretins, fools, morons, and lunatics…Cretins don’t even talk; they sort of slobber and stumble…Fools are in great demand, especially on social occasions. They embarrass everyone but provide material for conversation…Fools don’t claim that cats bark, but they talk about cats when everyone else is talking about dogs. They offend all the rules of conversation, and when they really offend, they’re magnificent…Morons never do the wrong thing. They get their reasoning wrong. Like the fellow who says that all dogs are pets and all dogs bark, and cats are pets, too, therefore cats bark…Morons will occasionally say something that’s right, but they say it for the wrong reason…A lunatic is easily recognized. He is a moron who doesn’t know the ropes. The moron proves his thesis; he has logic, however twisted it may be. The lunatic on the other hand, doesn’t concern himself at all with logic; he works by short circuits. For him, everything proves everything else. The lunatic is all idée fixe, and whatever he comes across confirms his lunacy. You can tell him by the liberties he takes with common sense, by his flashes of inspiration, and by the fact that sooner or later he brings up the Templars…There are lunatics who don’t bring up the Templars, but those who do are the most insidious. At first they seem normal, then all of a sudden…

Many homicidal lunatics are very quiet, unassuming people. Delightful fellows.

Sizzling Saturn, we’ve got a lunatic robot on our hands.

There are always some lunatics about. It would be a dull world without them.

The ordinary lunatic is generally a harmless, isolated case; since everyone sees that something is wrong with him, he is quickly taken care of. But the unconscious infections of groups of so-called normal people are more subtle and far more dangerous.

"It was lunar symbolism that enabled man to relate and connect such heterogeneous things as: birth, becoming, death, and ressurection; the waters, plants, woman, fecundity, and immortality; the cosmic darkness, prenatal existence, and life after death, followed by the rebirth of the lunar type ("light coming out of darkness"); weaving, the symbol of the "thread of life," fate, temporality, and death; and yet others. In general most of the ideas of cycle, dualism, polarity, opposition, conflict, but also of reconciliation of contraries, of coincidentia oppositorum, were either discovered or clarified by virtue of lunar symbolism. We may even speak of a metaphysics of the moon, in the sense of a consistent system of "truths" relating to the mode of being peculiar to living creatures, to everything in the cosmos that shares in life, that is, in becoming, growth and waning, death and ressurrection."
