At Princeton, Polkinghorne earnestly assures us, he and an "interdisciplinary group of scholars" recently spent three fruitful years making scientific estimates of God's plans for the destiny of the world. According to Polkinghorne and the Princetonians, the last things, when the Day of Judgment comes and the tombs are opened, are a bit like what we have now, but also a bit different: they are an "interplay between continuity and discontinuity." They do not include real Hell. They include only people who have not asked for admission to heaven, and these get some kind of after-life Bible classes. Beyond that, Heaven itself is a bit vague, but it includes pilgrimage and progress and increasing fullness. Heaven does not provide endless harps and psalms; nor, I think, does it afford Aquinas's favored pleasure of watching the tortures of the damned, nor Islam's seventy-two virgins per male martyr. In fact, I could not discover whether it included sex at all, but in their three years of deliberations Polkinghorne's group determined — scientifically, remember — that it may include some animals, especially domestic pets, although perhaps not too many of them, since it is permissible for God to "cull individuals in order to preserve the herd."
