A traveler to distant places should make no enemies.

We are not enemies, but friends. We must not be enemies. Though passion may have strained, it must not break, our bonds of affection.

You shall judge of a man by his foes as well as by his friends.

We are all full of weakness and errors; let us mutually pardon each other our follies—it is the first law of nature.

I hate who steals my solitude without, in exchange, offering me true company.

For friendship, like freedom, must be tended.

So long as you are secure you will count many friends; if your life becomes clouded you will be alone.

It is clear that the individual who persecutes a man, his brother, because he is not of the same opinion, is a monster.

Intelligent people tend to have less friends than the average person. The smarter you are, the more selective you become.

As the traveler who has once been from home is wiser than he who has never left his own doorstep, so a knowledge of one other culture should sharpen our ability to scrutinize more steadily, to appreciate more lovingly, our own.

The use of traveling is to regulate imagination by reality, and instead of thinking how things may be, to see them as they are.

If you want to succeed you should strike out on new paths, rather than travel the worn paths of accepted success.
