To say that a great genius is half-mad, while recognizing his artistic prowess, is worth as much as saying that he was rheumatic, or that he suffered from diabetes. Madness, in fact, is a medical expression to which a balanced critic should pay no more heed than he would to the accusation of heresy brought by the theologian, or to the accusation of immorality brought by the public prosecutor.

A touch of madness is, I think, almost always necessary for constructing a destiny.

There is no great genius without a mixture of madness

There are those to whom one must advise madness.

How does one objectively define madness ?

Enough madness? Enough? And how do you measure madness? - The Joker

Be silent and listen: have you recognized your madness and do you admit it? Have you noticed that all your foundations are completely mired in madness? Do you not want to recognize your madness and welcome it in a friendly manner? You wanted to accept everything. So accept madness too. Let the light of your madness shine, and it will suddenly dawn on you. Madness is not to be despised and not to be feared, but instead you should give it life. … If you want to find paths, you should also not spurn madness, since it makes up such a great part of your nature. … Be glad that you can recognize it, for you will thus avoid becoming its victim. Madness is a special form of the spirit and clings to all teachings and philosophies, but even more to daily life, since life itself is full of craziness and at bottom utterly illogical. Man strives toward reason only so that he can make rules for himself. Life itself has no rules. That is its mystery and its unknown law. What you call knowledge is an attempt to impose something comprehensible on life.

Internally, in itself, madness is an artistic desert. Nothing of any general interest can be said about it. Like sex. But the effects it has on the world outside it can be very interesting indeed. It has no other valid literary use.

Like madness is the glory of this life.

Madness is somewhere between chaos and having a dream.

Any madness in us gains from being expressed, because in this way one gives a human form to what separates us from humanity.

He may be mad, but there's method in his madness. There nearly always is method in madness. It's what drives men mad, being methodical.

Much Madness is Divinest Sense, to a Discerning Eye....
