Biography
Leslie was educated at Wadham College, Oxford, earning his B.A. in English Literature in 1962 and his M.Litt. in Classics in 1968. He is currently Professor emeritus at the University of Guelph, in Ontario, Canada.
In his book Universes, Leslie describes a philosophical parable in which an individual survives a firing squad of fifty expert marksmen unscathed. He offers two explanations for this remarkable event: either it is a fortuitous outcome, to be expected occasionally by pure chance among many thousands of attempted executions by firing squad; or it is intentional. Francis Collins references this parable in his book The Language of God: A Scientist Presents Evidence for Belief as part of his argument that the Anthropic Principle strongly suggests a Creator with intent.
Leslie has spoken as follows about his life's work:
What I have to contribute is some technical defense of the idea that if you had an infinitely rich [universe], it could be explained by reference to its value. Its goodness could be the creative force which had produced it. I think if I would like to be remembered as a philosopher for any one thing, that would be the thing I'd most like to be remembered for.
Pantheism
Leslie is a pantheist.[1][2] His philosophical work takes influence from David Lewis, Plato and Spinoza.[1][3]
In his book Infinite Minds: A Philosophical Cosmology (2001), Leslie argues for a pantheistic universe in which everything exists in a divine mind. Philosopher Brendan Sweetman commented that the book promotes a "highly speculative, pantheistic theory that is fascinating in its own way, but that will probably convince very few."[1] Leslie's book is unique because he accepts and uses arguments for the existence of God which are usually used to support theism such as a version of the cosmological argument and the design argument based on fine-tuning, but he explains these in a pantheistic way.[4]
