Speculative fiction

Any fiction of a speculative nature (but especially science fiction, fantasy and horror) that feels embarrassed to call itself science fiction, fantasy or horror.

Interestingly, Robert Heinlein may have originated the term in 1947, in an essay titled “On the Writing of Speculative Fiction” in Of Worlds Beyond edited by Lloyd Arthur Eshbach from Fantasy Press and later reprinted by Advent.

We forgive him.

OUSFG had to have Speculative in its title, as the Oxford proctors found SF unacceptable.
