Professor David Benatar is a South African philosopher, academic and author, and head of the philosophy department at the University of Cape Town in South Africa. He is best known for his defence of antinatalism, the view that it is immoral to have children (though more specifically, to bring new sentient beings into existence). Professor Benatar speaks to Alex about the asymmetry of pleasure and pain, and the two debate whether being anti-birth commits one to being pro-death.
