Knowledge without mileage equals bullshit.

Books are cool, but knowledge without mileage doesn't mean anything to me.

Bullshit, that's how I feel. Total fucking bullshit.

Belief has nothing to do with knowledge, & credo ut intelligam [I believe in order that I might understand] is horseshit. (p. 209)

I'm not dumb. I just have a command of thoroughly useless information.

Luxury of freedom hates the discipline of knowledge.

Fools hate knowledge

Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful.

I have no use for knowledge that has not been preceded by a sensation

Knowledge is of no value unless you put it into practice.

Knowledge without work is insanity, and work without knowledge is vanity. Know that any science which does not remove you today far from apostasy, and does not carry you to obedience, will not remove you tomorrow from the fire of hell.

Close beside my knowledge lies my black ignorance.

There is no mastery without mistakes, and there is no learning later without the courage to be rubbish.

Zeal without knowledge is fire without light.
