“Man is slave of emotions when they arise, and master of them when they don't.”

“Love is not an idea, not a feeling, not a sensation, not a sentiment, not a passion, not even an emotion. It is becoming and being not... Ultimate nothingness! Complete self-annihilation!”

“Ideas can't die, not because they are conceived by humans, but because time begets them.”

“The intelligent have plans; the wise have principles.”

“Imagination is thinking beyond language.”

“Learn, or you'll be made to learn.”

“The most crucial problem with intellectual learning is that it receives the unknown on the grounds of the known.”
