I have never examined the subject of humor until now. I am surprised to find how much ground it covers. I have got its divisions and frontiers down on a piece of paper. I find it defined as a production of the brain, as the power of the brain to produce something humorous, and the capacity of percieving humor.

We love old travelers: we love to hear them prate, drivel and lie; we love them for their asinine vanity, their ability to bore, their luxuriant fertility of imagination, their startling, brilliant, overwhelming mendacity.

In America, we hurry-which is well; but when the day's work is done, we go on thinking of losses and gains, we plan for the morrow, we even carry our business cares to bed with us...we burn up our energies with these excitements, and either die early or drop into a lean and mean old age at a time of life which they call a man's prime in Europe...What a robust people, what a nation of thinkers we might be, if we would only lay ourselves on the shelf occasionally and renew our edges!

Books are for people who wish they were somewhere else.
