CLAUDE BERNARDMan can learn nothing unless he proceeds from the known to the unknown.

It is what we know already that often prevents us from learning.

Our ideas are only intellectual instruments which we use to break into phenomena; we must change them when they have served their purpose, as we change a blunt lancet that we have used long enough.
