Knowledge is just a foundation. The whole point of a foundation is to build on it.

Never confuse a hunger for knowledge with a thirst for truth.

It's not the wound that teaches, but the healing.

When Socrates said he knew nothing he still thought he knew more than anyone else.

Ah, child and youth, if you knew the bliss which resides in the taste of knowledge, and the evil and ugliness that lies in ignorance, how well you are advised to not complain of the pain and labor of learning.

Know yourself? Why not forget yourself instead?
