"Learning is the only thing the mind..." - Quote by Leonardo Da Vinci

“Everything proceeds from everything else and everything becomes everything, and everything can be turned into everything else.”

“Nature alone is the master of true genius.”

“The desire to know is natural to good men.”

“Don't let your learning lead to knowledge. Let your learning lead to action.”

“I hear and I forget. I see and I remember. I do and I understand.”

“Take what's useful, discard what is not.”

“Let us, then, take our compass; we are something, and we are not everything. The nature of our existence hides from us the knowledge of first beginnings which are born of the nothing; and the littleness of our being conceals from us the sight of the infinite. Our intellect holds the same position in the world of thought as our body occupies in the expanse of nature.”

“We know truth when we see it, from opinion, as we know when we are awake that we are awake.”

“Every man is ignorant - just on different subjects.”
