Sleeping is no mean art: for its sake one must stay awake al... - Friedrich Nietzsche

"And those who were seen dancing were thought to be insane by those who could not hear the music."

"When we are tired, we are attacked by ideas we conquered long ago."

"Love is blind; friendship closes its eyes."

"The snake which cannot cast its skin has to die. As well the minds which are prevented from changing their opinions; they cease to be mind."

"We talk so abstractly about poetry because all of us are usually bad poets."
