My mother taught me three things: respect, knowledge, search for knowledge. It's an eternal journey.

Knowledge inspires courage. I'm not sceptical but I'd sooner know than believe.

Close beside my knowledge lies my black ignorance.

Knowledge kills action; action requires the veils of illusion.

Our treasure lies in the beehive of our knowledge. We are perpetually on the way thither, being by nature winged insects and honey gatherers of the mind.

Partial knowledge is more triumphant than complete knowledge; it takes things to be simpler than they are, and so makes its theory more popular and convincing.
