“Often-times it's madness, not genius that moves the world forward. Who else but the mad would reach so far, stretching for the impossible and, in so doing, prove the impossible possible!”

“It is almost impossible to be a doctor and an honest man, but it is obscenely impossible to be a psychiatrist without at the same time bearing the stamp of the most incontestable madness: that of being unable to resist that old atavistic reflex of the mass of humanity, which makes any man of science who is absorbed by this mass a kind of natural and inborn enemy of all genius.”

“Alice: This is impossible.
The Mad Hatter: Only if you believe it is.”

“Van Gogh writing his brother for paints
Hemingway testing his shotgun
Celine going broke as a doctor of medicine
the impossibility of being human
Shakespeare a plagiarist
Beethoven with a horn stuck into his head against deafness
the impossibility the impossibility
Nietzsche gone totally mad
the impossibility of being human
all too human
this breathing
in and out
out and in
these punks
these cowards
these champions
these mad dogs of glory
moving this little bit of light toward us
impossibly.”

“Ah," said the jailer, "do not always brood over what is impossible, or you will be mad in a fortnight.”

“Men are so necessarily mad, that not to be mad would amount to another form of madness.”

“Impossible to accede to truth by opinions, for each opinion is only a mad perspective of reality.”

“Each of us believes, quite unconsciously of course, that we alone pursue the truth, which the rest are incapable of seeking out and unworthy of attaining. This madness is so deep-rooted and so useful that it is impossible to realize what would become of each of us if it were someday to disappear.”

“Possible impossibility emerges from an impossible possibility, or possibly, impossible possibility blooms from the impossibly possible impossibility.”

“To the atheist, the world is filled with madness and crazy people who believe in superstitions that cannot even prove to be true.”
