John Leslie

The fine-tuning of the universe is not a coincidence we can ignore: it calls for an explanation.

Life

Canadian philosopher born in 1940, professor emeritus at the University of Guelph. He is known for his work on the fine-tuning of the universe and on philosophical cosmology. He argues that this fine-tuning calls for an explanation, and offers a neoplatonist view in which the universe exists because it is good.

Leslie, Value and Existence (1979) ; Universes (1989)

Is the mind more than matter?Mind and body
MaterialismDualism

Leslie, Infinite Minds (2001)

Do good and evil exist objectively?Status of morality
Anti-realism (morality is human-made)Moral realism (objective moral truths)
Stated

Ethical requirements are objective facts, and they are what ultimately explain why anything exists.

Leslie, Value and Existence (1979)

No given meaning (absurd, to be created)Objective meaning (nature, God, the Good)

If goodness itself brings the world into being, existence has an objective point.
