A Gift from the Culture
"A Gift from the Culture", published in 1987, is a short work of space opera, by the Scottish science fiction author Iain M. Banks. The story is an early venture into the "complex and unusual and very distant" setting of the Culture, which Banks would further develop through various of full length novels, stories, and his essay "A Few Notes on the Culture".
The Culture
The Culture is a posthuman society, which originally arose when seven or eight roughly humanoid space-faring species coalesced into a quasi-collective (a group-civilization) ultimately consisting of approximately thirty trillion (short scale) sentient (more properly, sapient) beings (this includes artificial intelligences). In Banks's universe, a good part (but by no means an overwhelming percentage) of all sentient species is of the "pan-human" type, as noted in "Matter".
