There are those to whom one must advise madness.

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

Like madness is the glory of this life.

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.

Madness is somewhere between chaos and having a dream.

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....

Madness in method, that's genius

Madness need not be all breakdown. It may also be break-through. It is potential liberation and renewal as well as enslavement and existential death.

The real madness probably is not another thing that the wisdom itself that, tired of discovering the shames of the world, has taken the intelligent resolution to become mad

Sometimes it’s only madness that makes us what we are.

When life itself seems lunatic, who knows where madness lies? Perhaps to be too practical may be madness. To surrender dreams, this may be madness ...Maddest of all is to see life as it is and not as it should be.

Though this be madness, yet there is method in't.

I had to admit, standing there, that sometimes you just gotta admire the passion of the truly insane — a passion that bulls right past all sense or reason.
