Kirsty Young's castaway this week is the author, Brian Aldiss.
He is best known for pioneering, alongside JG Ballard, a new wave of British science fiction writing in the 1960s. He says science fiction is not so much a prediction of the future as a metaphor for the human condition; and for him, at least, writing it offered an escape route and a filter through which to view his own extraordinary upbringing.
He grew up in a small Norfolk village in a very devout and austere home. While his father was distant, his mother was still suffering from the grief after her first child, a daughter, was still-born. He was the second child and even when he was very small, remembers feeling a strong sense of his mother's disappointment in him.
The army finally offered a way out for him and it was on his return to England that he started writing seriously while also working in a bookshop. One of his early works was a short story describing the sadness felt by a boy who was never able to please his parents, which was turned into a film by Stanley Kubrick.
While he remains best known for his science fiction writing - and has won every major award in the field - he has also written novels, poetry and biographies and short stories. Now, he says, he aims not for high sales but to become a better and better writer.
