Excessive sorrow laughs. Excessive joy weeps.

Madness is somewhere between chaos and having a dream.

He was born with a gift of laughter and a sense that the world was mad.

We poisoned it with laughter. All around within it we rose, we fell, we rose again, mystified by Fate, hysterical with chance. We fired our laughs like cannons at its heart!

A vast silence reigned over the land. The land itself was a desolation, lifeless, without movement, so lone and cold that the spirit of it was not even that of sadness. There was a hint in it of laughter, but of laughter more terrible than any sadness-a laughter that was mirthless as the smile of the Sphinx, a laughter cold as the frost and partaking of the grimness of infallibility. It was the masterful and incommunicable wisdom of eternity laughing at the futility of life and the effort of life. It was the Wild, the savage, frozen-hearted Northland Wild.

Madness breeds madness.

Made still a blund'ring kind of melody;
Spurred boldly on, and dashed through thick and thin,
Through sense and nonsense, never out nor in.
Free from all meaning, whether good or bad,
And in one word, heroically mad.

Like madness is the glory of this life.
