Today you can buy the Dialogues of Plato for less than you would spend on a fifth of whiskey, or Gibbon's Decline and Fall of the Roman Empire for the price of a cheap shirt. You can buy a fair beginning of an education in any bookstore with a good stock of paperback books for less than you would spend on a week's supply of gasoline.

Adventure is nothing but a romantic name for trouble.

Actually, all education is self-education. A teacher is only a guide, to point out the way, and no school, no matter how excellent, can give you education. What you receive is like the outlines in a child’s coloring book. You must fill in the colors yourself.

When at the typewriter I am no longer where I site but am away across the mountains, in ancient cities or on the Great Plains among the buffalo. Often I think of what pitiful fools are those who use mind-altering drugs to seek feelings they do not have, each drug taking a little more from what they have of mind, leaving them a little less. Give the brain encouragement from study, from thinking, from visualizing, and no drugs are needed.

In the United States we have concentrated tremendous sums of money on the educational plant, seemingly with the idea that the right number of buildings will turn out the right number of graduates. Yet the teachers who actually instruct the future citizens of our country are more often than not miserably paid. If in the future we find ourselves with a lot of fourth-rate citizens, we have only ourselves to blame.

The trail is the thing, not the end of the trail. Travel too fast, and you miss all you are traveling for.

There is no man more dangerous than one who does not doubt his own rightness.
