Early life

edit

Leiber was born in 1938 in Chicago, Illinois[1][3] to writers Fritz Leiber and Jonquil Stephens Leiber.[3] After completing his primary and secondary schooling at the University of Chicago Laboratory Schools, he went on to receive A.B. (1958), A.M. (1960) and Ph.D. (1967) degrees in philosophy from the University of Chicago and a B.Phil (1972) from St. Catherine's College, Oxford.[4]

Leiber had two children, attorney and novelist ArLynn Leiber Presser and singer and actor KC Leiber.[5]

Career

edit

Leiber had numerous academic appointments, including an instructorship at Memphis State University (1962–1963) and assistant professorships at Utica College of Syracuse University (1963–1965), the State University of New York at Buffalo (1966–1968) and Lehman College (1968–1977). While at the latter institution, he held visiting appointments at King's College London (honorary visitor; 1970–1971), St. Catherine's College, Oxford (philosophy tutor; 1971–1972) and the Massachusetts Institute of Technology (visiting scientist; 1976–1978).[6] A full professor at the University of Houston from 1978 onward,[7] Leiber ended his career at Florida State University.

Death

edit

Leiber died on March 22, 2016, in Tallahassee, Florida, from prostate cancer.[5][8]

Works

edit

Leiber's publications encompass a number of subjects, including philosophy, psychology, linguistics, and cognitive science.[3] He published several papers on Alan Turing's Turing test and Turing's mathematical Turing machines and biological achievements, arguing that Turing Test passage requires actual, real time, reliable passage, thus excluding challenges to the Test by John Searle and others (Leiber 2006a, 1995, 1991)[9] He also defends Turing's demand for a biology that excludes selectionist and functional explanations (Leiber 2006a, 2001) and he has offered a related critique of evolutionary psychology (Leiber 2008, 2006b). In several works (Leiber 1991,1988, 1975) he articulates the nativist and rationalist linguistics of Noam Chomsky.[10] In a critical notice of Leiber's Invitation to Cognitive Science, Diane Proudfoot and Jack Copeland comment that "He provides a rationale for the Turing test which knits together the motivational remarks of Turing's 1950 article more satisfyingly than any previously proposed and he draws attention to Turing's anticipation of connectionism in 1948."[11] While acknowledging that Leiber's interpretation of Turing's 1936 paper is widely shared, they argue that this consensus "distorts both Turing's achievement and the epistemic status of the computational theory of mind." Proudfoot and Copeland also comment that "Leiber upsets the common view of Wittgenstein by arguing that theses in the Philosophical Investigations commit Wittgenstein to a scientific approach the mind and encourage a specifically computational theory of mind...[stressing] central elements of Wittgenstein's constructive accounts of mind and language." However, they are critical of Leiber's audacious interpretation.

Some of both his fiction and non-fiction books and papers have dealt with intelligence and consciousness.[12] Larry Hauser credits Leiber's dialogue, Can Animals and Machines Be Persons? for articulating the claim that "the solipsistic predicament pertains to individuals not species," so that if one can reliably tell that other humans have minds it would be sheer chauvinism to maintain one could never know whether something non-human had a mind.[13] Lesley McLean comments that "Justin Leiber, who Dennett cites as a source for exposing certain hidden agendas distorting objective research into animal consciousness, himself offers a subjective account for why indeed we might doubt the link between moral standing and having of a mind [Leiber 1988]...What is interesting is that neither Descartes nor Leiber thinks animals to be conscious, yet they nevertheless think them worthy of moral consideration."[14] Peter Singer, Mary Midgley, and others cite L. C. Rosenfield's From Beast-Machine to Man-Machine: Animal Soul in French Letters from Descartes to LaMettrie (New York, Oxford University Press, 1941) for a ghastly account of animal cruelty by unnamed Cartesians, but Singer and the rest fail to mention that Rosenfield dismisses the account as a pious anti-Cartesian fabrication, and further, that Rosenfield maintains that Descartes himself was never accused of cruelty to animals, nor did Descartes maintain that animals could not feel pain[14] (Leiber 1988).

Begun while he was a visiting scientist at MIT, Justin Leiber's first novel, Beyond Rejection, starts with a lengthy description of a “mind implant” operation in which the software mind of one individual is inserted into the hardware brain and body of another. Provocative and detailed, the description has been anthologized in several text books, most notably in Douglas Hofstadter and Daniel Dennett's The Mind's I. The novel's protagonist, with memories of a male body, awakens to a female one and must find a way beyond rejection. In Beyond Humanity, the protagonist deals with the claims to personhood of both apes and computers – themes that Hackett Publishing suggested might also be incorporated into a dialogue, Can Animals and Machines Be Persons? In Beyond Gravity, Leiber's protagonist discovers that earth has long been studied by alien “anthropologists,” who write articles about humans which appear in a journal whose title might be translated into humanese as “Primitivity Review.” As this description suggests, Leiber's Beyond trilogy is largely taken up with issues in philosophy and cognitive science. The same might not be said of Leiber's sword and sorcery novels The Sword and the Eye and The Sword and the Tower.
