If you're old, don't try to change yourself, change your environment.

We shouldn't teach great books; we should teach a love of reading.

Unable to understand how or why the person we see behaves as he does, we attribute his behavior to a person we cannot see, whose behavior we cannot explain either but about whom we are not inclined to ask questions.

Education is what survives when what has been learnt has been forgotten.

We admire people to the extent that we cannot explain what they do, and the word "admire" then means "marvel at".

The simulated approval and affection with which parents and teachers are often urged to solve behavior problems are counterfeit. So are flattery, backslap-ping, and many other ways of "winning friends."

Overcrowding can be corrected only by inducing people not to crowd, and the environment will continue to deteriorate until polluting practices are abandoned.
