As any schoolchild learns, the time shuttler who goes into the past introduces an alien variable into the spacio-temporal matrix at the instant when he emerges. The time stream forks, an alternative universe is born in which his visit is given its proper place, and when he returns it will be to a future level in the new world which he has created. His own universe is forever barred to him.

I figure Gleeps is an Investigator. As far back as you want to go, he always has been, and as far ahead as you want to go in a bender, he always will be. Everywhere you go in this or any other universe he is, was and will be. He’s everywhen and everywhere—but I said that before.

The first of the fan organizations….was a counterpart to the Gernsbackian philosophy of science fiction.

Obviously, no author can present vividly and realistically for the benefit of the latter, experienced readers certain problems of future life and relations, of life in space ships and space colonies, that everyone realizes will and must occur, when sixth-grade children are reading them. They would not understand what was really being presented, anymore [sic] than they would understand a bald, literal statement of the theories of Freud and his school.

F. M. Busby, who will probably chair the 1961 World Science [sic] Convention in Seattle, seconds this with the opinion that a new reader, going over the output of the ‘great’ days of 1946 and that of 1959, would consider more of the 1959 stories really good. Theodore Sturgeon once attacked it from the other side with what has become known as Sturgeon’s Law: ‘Ninety per cent of everything is crud.’ The remaining ten per cent is what we call ‘good’ and ten per cent of that—one story in a hundred—is ‘really good’.
