Sometimes the cost of integrity is the loss of a friend.

Most of us sleepwalk through our lives. We take all its glories, its wine, food, love, and friendship, its sunsets and its stars, its poetry and fireplaces and laughter, for granted. We forget that experience is not, or should not be, a casual encounter, but rather an embrace. Consequently, for too many of us, when we come to the end, we wonder where the years have gone. And we suspect we have not lived.

So long as men and women are free, no one is safe. People will be in danger because others can't operate vehicles responsibly or shoot straight. Because physicians are sometimes incompetent and lawyers dishonest. But most of all they will be in danger from ideas. It is the price we willingly pay to be free. Nor would we have it any other way.

The real problem has to do with the inability by people to admit that a position they've held a long time might be wrong. That's all. Not that it is. Just that it might be. I don't know why it is, but we tend to fall in love with things we believe, Threaten them, and you threaten us.

An optimist is somebody who thinks our various political and social systems, schools and churches, support groups and Boy Scout troops, jury trials and congressional committees, are on the up-and-up.

See what the world looks like from orbit. Well, in that way, at least, there was profit to be had. Nobody could look down at the planet, green and blue, with no borders in evidence and no sign of human habitation, and not get his perspective forever altered.

Tides are like politics. They come and go with a great deal of fuss and noise, but inevitably they leave the beach just as they found it. On those few occasions when major change does occur, it is rarely a good news.
