(1938-2016) US academic philosopher from 1962 at various universities and author, son of Fritz Leiber; he used sf as a medium for speculation in his field of interest, the philosophy of the mind. Thus his first novel, Beyond Rejection (1980), which begins the Beyond sequence, deals in considerable detail with the problems of acclimatization associated with transplanting the recorded mind of a man into the body of a woman (see Identity Transfer) who incidentally has a prehensile tail, a physical modification to aid activity in free-fall environments. In Beyond Humanity (1987) Leiber contrasts human Intelligence with those of Computers and enhanced-intelligence chimpanzees (see Apes as Human; Uplift) as humans, computer and chimpanzee cooperate to contact Extraterrestrial intelligence (see First Contact). The sequence concludes with Beyond Gravity (1988), set in twenty-second-century Houston and Oxford. Leiber also wrote a number of academic books on similar themes, including Can Animals and Machines Be Persons? (1985), which explores an sf scenario – a legal case between a space-exploration company and a Civil Liberties Union over whether a chimpanzee and a computer used on a Space Station should be treated as tools or as employees.
