Trade isn't about goods. Trade is about information. Goods sit in the warehouse until information moves them.

Deal with the Devil if the Devil has a constituency - and don't complain about the heat.

The warrior may fight for gold or for an immediate gain, or for something to take home for the winter to feed the family. The soldier is part of a more complex society. He's fighting for a group ethic of some sort.

Science fiction is a dialogue, a tennis match, in which the Idea is volleyed from one side of the net to the other. Ridiculous to say that someone 'stole' an idea: no, no, a thousand times no. The point is the volley, and how it's carried, and what statement is made by the answering 'statement.' In other words — if Burroughs initiates a time-gate and says it works randomly, and then Norton has time gates confounded with the Perilous Seat, the Siege Perilous of the Round Table, and locates it in a bar on a rainy night — do you see both the humor and the volley in the tennis match?

For me the purest and truest art in the world is science fiction.

Culture is how biology responds and makes its living conditions better.
