The Molinist doctrine that God has middle knowledge requires that God knows the truth-values of counterfactuals of freedom, propositions about what free agents would do in hypothetical circumstances. A well-known objection to middle knowledge, the grounding objection, contends that counterfactuals of freedom have no truth-value because there is no fact to the matter as to what an agent with libertarian freedom would do in counterfactual circumstances. Molinists, however, have offered responses to the grounding objection that they believe are adequate for maintaining the coherence of middle knowledge. I argue that these responses to the grounding objection are not adequate, and that what I call the ‘generic grounding objection’ still poses a serious challenge to middle knowledge.

One problem facing those who attempt to reconcile divine foreknowledge with human freedom is to explain how a temporal God can have knowledge of the future, if the future does not exist. In her recent book, "The Dilemma of Freedom and Foreknowledge," Linda Zagzebski attempts to provide an explanation by making use of a four-dimensional model in which the past, present and future exist. In this note I argue that the model Zagzebski offers to support the coplausibility of divine foreknowledge and human freedom is inconsistent with the A-theory of time she propounds.

Molinism, named after Luis de Molina, is a theological system for reconciling human freedom with God's grace and providence. Presupposing a strongly libertarian account of freedom, Molinists assert against their rivals that the grace whereby God cooperates with supernaturally salvific acts is not intrinsically efficacious. To preserve divine providence and foreknowledge, they then posit "middle knowledge", through which God knows, prior to his own free decrees, how any possible rational agent would freely act in any possible situation. Beyond this, they differ among themselves regarding the ground for middle knowledge and the doctrines of efficacious grace and predestination.

This paper examines the question of whether the theory of simply foreknowledge (SF) provides God with greater providential control than does the theory of present knowledge (PK). It is claimed by the proponents of SF that a deity lacking such knowledge would not be able to provide the sort of providential aid commonly thought by theists to be given by God. To see whether this is the case I first distinguish two different versions of how God’s foreknowledge is accessed according to simple foreknowledge. These two versions are then utilized to examine seven different areas of divine providence to assess the utility of simple foreknowledge. I conclude that SF affords no greater providential control than PK.

The doctrine of Middle Knowledge presupposes that conditionals of freedom (statements of the form 'If A were circumstances C, he would perform X') can be true. Such conditions are, where true, not true in virtue of the truth of any categorical proposition. Nor can their truth be modelled in terms of comparative similarity of possible worlds, because the structure of possible worlds is a necessary one, whereas the connection between antecedent and consequent of a conditional of freedom is a contingent one. Lewis and Stalmaker are committed to 'conditional fatalism', the view that things only would go a certain way if they would have to go that way. Although commitment to conditional fatalism does not itself import a commitment to fatalism, it is hard to find a separate motivation for it.

I defend the compatibility of the classical theistic doctrine of divine providence, which includes infallible foreknowledge of all future events, with a libertarian understanding of creaturely free will. After setting out the argument for theological determinism, which purports to show the inconsistency of foreknowledge and freedom, I reject several responses as inadequate and then defend the ‚Ockhamist‛ response as successful. I further argue that the theory of middle knowledge or ‚Molinism‛ is crucial to the viability of the Ockhamist response, and proceed to defend Molinism against the most pressing objections. Finally, I argue that a proper understanding of the Creator-creature relationship accounts for why no explanation can be given for how God’s middle knowledge comes about.

I use some ideas of Keith DeRose's to develop an (invariantist!) account of why sceptical reasoning doesn't show that I don't know that I'm not a brain in a vat. I argue that knowledge is subject to the risk-of-error constraint: a true belief won’t have the status of knowledge if there is a substantial risk of the belief being in error that hasn’t been brought under control. When a substantial risk of error is present (i.e. beliefs in propositions that are false in nearby worlds), satisfying the constraint requires bringing the risk under control. This is achieved either by sensitivity, i.e. you wouldn’t have the belief if it were false, or by identifying evidence for the proposition. However, when the risk of error is not substantial (i.e. beliefs in propositions that are not false in nearby worlds), the constraint is satisfied by default. My belief that I am not a brain in a vat is insensitive and I have no evidence for it, but since it is not false in nearby worlds, it satisfies the constraint by default.

While it might seem prima facie plausible that divine foreknowledge is all that is needed for prophecy, this seems incorrect. To issue a prophecy, God hasto know not just how someone will act, but how someone would act were the prophecy issued. This makes some think that Middle Knowledge is required.I argue that Thomas Flint’s two Middle Knowledge based accounts of prophecy are unsatisfactory, but one of them can be repaired. However the resources needed for repair also yield a sketch of a foreknowledge-only account of prophecy.
