Alexander Robert Pruss (/prʌs/; born January 5, 1973) is a Canadian philosopher and mathematician.
[1][2][3] He is also the author of the books, Actuality, Possibility and Worlds (2011), and One Body: An Essay in Christian Sexual Ethics (2012), and a number of academic papers on religion and theology.
[6] Pruss graduated from the University of Western Ontario in 1991 with a Bachelor of Science degree in mathematics and physics.
Pruss began teaching philosophy at Georgetown University in 2001, earning tenure in 2006.
[8] Pruss is a critic of David Lewis's "extreme modal realism," and instead gives "a combined account" of Leibnizian and Aristotelian modality, which integrates the "this-worldly capacities" of the Aristotelian view and Leibniz's account of possible worlds as thoughts in the mind of God.
