[Science is] the literature of truth.

Economy is a savings-bank, into which men drop pennies, and get dollars in return.

The trouble with most folks isn't their ignorance. It's knowin' so many things that ain't so.

As a general rule, if you want to get at the truth - hear both sides and believe neither.

Knowledge is like money, the more a man gits the more he hankers for.

It is true that wealth won't make a man virtuous, but I notice there ain't anybody who wants to be poor just for the purpose of being good.

Rumor is like bees; the more you fight them the more you don't get rid of them.
