Your mind will serve you better than any trinket under the suns...It is a weapon...and like any weapon, you need practice to be any good at wielding it.

I'd hoped for someone who was remarkably intelligent, but disadvantaged by home circumstance, someone who only needed an hour's extra tuition a week to become some kind of working-class prodigy. I wanted my hour a week to make the difference between a future addicted to heroin and a future studying English at Oxford. That was the sort of kid I wanted, and instead they'd given me someone whose chief interest was in eating fruit. I mean, what did he need to read for? There's an international symbol for the gents' toilets, and he could always get his mother to tell him what was on television.

When did you get so clever?When I realized I wasn't as clever as I thought.

I disapprove of matrimony as a matter of principle.... Why should any independent, intelligent female choose to subject herself to the whims and tyrannies of a husband? I assure you, I have yet to meet a man as sensible as myself! (Amelia Peabody)

Intelligent men are dangerous.

You are intelligent if you know what you do not know.
