Call the claim, common to many in the Christian intellectual tradition, that Christ, in virtue of his created human intellect, had certain, infallible exhaustive foreknowledge the Foreknowledge Thesis. Now consider what I will call the Conditional: If the Foreknowledge Thesis is true, then Christ’s created human will lacked an important sort of freedom that we mere humans have. Insofar as many, perhaps all, of the people who affirm the Foreknowledge Thesis also wish to affirm the robust freedom of Christ’s human (...) will, the truth of the Conditional would be most unwelcome to them. I consider an argument in support of the Conditional from the necessary conditions for deliberation, arguing that the argument fails. (shrink)

This paper argues that, with certain provisos, predicting one's future actions is incompatible with rationally deliberating about whether to perform those actions. It follows that fully rational omniscient agents are impossible, since an omniscient being could never rationally deliberate about what to do . Consequently, theories that explain practical reasons in terms of the choices of a perfectly rational omniscient agent must fail. The paper considers several ways of defending the possibility of an omniscient agent, and concludes that while some (...) of these may work, they are inconsistent with the aim of explaining practical normativity by appeal to such an agent.
