Be charitable and indulge to everyone, but thyself.
Knowledge of what is does not open the door directly to what should be. If one asks the whence derives the authority of fundamental ends, since they cannot be stated and justifed merely by reason, one can only answer: they exist in a healthy society as powerful traditions, which act upon the conduct and aspirations and judgements of the individuals; they are there, that is, as something living, without its being necessary to find justification for their existence. They come into being not through demonstration but through revelation, through the medium of powerful personalities. One must not attempt to justify them, but rather to sense their nature simply and clearly.
I became a so-called science fiction writer when someone decreed that I was a science fiction writer. I did not want to be classified as one, so I wondered in what way I'd offended that I would not get credit for being a serious writer. I decided that it was because I wrote about technology, and most fine American writers know nothing about technology. I got classified as a science fiction writer simply because I wrote about Schenectady, New York. My first book, Player Piano, was about Schenectady. There are huge factories in Schenectady and nothing else. I and my associates were engineers, physicists, chemists, and mathematicians. And when I wrote about the General Electric Company and Schenectady, it seemed a fantasy of the future to critics who had never seen the place.
