“Now I am about to take my last voyage, a great leap in the dark.”

Variant: I will take the sun in my mouth and leap into the ripe air.

Context: The rational intellect doesn't have a great deal to do with love, and it doesn't have a great deal to do with art. I am often, in my writing, great leaps ahead of where I am in my thinking, and my thinking has to work its way slowly up to what the "superconscious" has already shown me in a story or poem.

The Better Part (1901)
Context: I believe that brutality tends to defeat itself. Prizefighters die young, gourmands get the gout, hate hurts worse the man who nurses it, and all selfishness robs the mind of its divine insight, and cheats the soul that would know. Mind alone is eternal. He, watching over Israel, slumbers not nor sleeps. My faith is great: out of the transient darkness of the present the shadows will flee away, and Day will yet dawn. I am an Anarchist.
