Why Can’t Angels See Our Future? Aquinas’s View of the Relation between Continuous and Discrete Time

Abstract

Aquinas’s account of angelic cognition presents an intriguing puzzle. Aquinas denies, for both theological and philosophical reasons, that angelic natural knowledge extends to future contingents. Yet Aquinas also insists, strictly for philosophical reasons, that angelic life is measured by a “discrete time” radically distinct from our physical universe’s continuous time. How can two times share the same “now,” such that what is future for us would also be future for the angels? Aquinas does little to address this problem, but I propose two possible solutions. Both solutions argue that angelic instants, like the instants of aeviternity and eternity, can be simultaneous with physical time periods, but only if the corresponding act aims at physical things. This means the angel cannot “skip” physical time, and so determinately aligns angelic instants with physical times. The solutions diverge over whether the extensionless angelic instant is simultaneous with the physical time period all at once, like God’s eternity, or successively, thanks to a temporally extended simultaneity-relation. The first solution prevents angelic natural foreknowledge of what follows an angelic intervention, since intervention requires a new angelic instant. The second solution prevents angelic natural foreknowledge tout court by tying “all-at-once” simultaneity to causal knowledge, which is God’s unique privilege.
