The system of nature, of which man is a part, tends to be self-balancing, self-adjusting, self-cleansing. Not so with technology.
I have no doubt that it is possible to give a new direction to technological development, a direction that shall lead it back to the real needs of man, and that also means: to the actual size of man. Man is small, and, therefore, small is beautiful. To go for giantism is to go for self-destruction.
Call a thing immoral or ugly, soul-destroying or a degradation of man, a peril to the peace of the world or to the well-being of future generations; as long as you have not shown it to be ''uneconomic'' you have not really questioned its right to exist, grow, and prosper.
