Our knowledge can only be finite, while our ignorance must necessarily be infinite.

True ignorance is not the absence of knowledge, but the refusal to acquire it.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride, or laziness of mind.

A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.

How true it is that men live for Things and women for People!

I thought I’d learn a few new words, but the men were too shocked to even swear this time.
