There is a longstanding argument that purports to show that divine foreknowledge is inconsistent with human freedom to do otherwise. Proponents of this argument, however, have for some time been met with the following reply: the argument posits what would have to be a mysterious non-causal constraint on freedom. In this paper, I argue that this objection is misguided – not because after all there can indeed be non-causal constraints on freedom (as in Pike, Fischer, and Hunt), but because (...) the success of the incompatibilist's argument does not require the real possibility of non-causal constraints on freedom. I contend that the incompatibilist's argument is best seen as showing that, given divine foreknowledge, something makes one unfree – and that this something is most plausibly identified, not with the foreknowledge itself, but with the causally deterministic factors that would have to be in place in order for there to be infallible foreknowledge in the first place.

. In this essay, we move to further advance the work done on God and emotions by RT Mullins, exploring the role exhaustive divine foreknowledge plays as it relates to God’s emotional life. Given our preliminary investigation at the intersection of divine foreknowledge and divine emotions, and focusing specifically on the neoclassical theistic conception of God, we argue that in light of God’s foreknowledge, his emotional life is dissimilar when compared to that of his creation. That said, (...) our primary aim is one of exploration: Should divine foreknowledge play a role in how we understand God’s emotional life? Given our analysis, we answer in the affirmative. (shrink)

Boethius represents one of the most important milestones in Christian reflection about fate and providence, especially considering that he takes into account Proclus’ contributions to these questions. For this reason, The Consolation of philosophy is considered a crucial work for the development of this topic. However, Boethius also exposes his ideas in his commentary on the book that constitutes one of the oldest and most relevant texts on the problem of future contingents, namely Aristotle’s De interpretatione. Although St. Thomas refers (...) to Boethius many times in his systematic works and even devotes two commentaries to two of his theological opuscules, it is of special interest that both authors composed a commentary on the abovementioned work by Aristotle. The commentary of Saint Thomas does not interpret the whole book, but it does study the pages about future contingents in dialogue with Boethius. We will study such texts in our presentation. They constitute one of the greatest contributions of Aquinas to the problem of necessity and contingency and therefore to the vexata quaestio of divine intervention in the world and particularly in human free will. Not only Augustin but also Aristotle (read by Boethius) and Nemesius of Emesa will be decisive in Aquinas’ perception of this matter. (shrink)

Many philosophers maintain that the ability to do otherwise is compatible with comprehensive divine foreknowledge but incompatible with the truth of causal determinism. But the Fixity of the Past principle underlying the rejection of compatibilism about the ability to do otherwise and determinism appears to generate an argument also for the incompatibility of the ability to do otherwise and divine foreknowledge. By developing an account of ability that appeals to the notion of explanatory dependence, we can replace the (...) Fixity of the Past with a principle that does not generate this difficulty. I develop such an account and defend it from objections. I also explore some of the account's implications, including whether the account is consistent with presentism. (shrink)

Certain kinds of prediction, foreknowledge, and future‐oriented action appear to require settled future truths. But open futurists think that the future is metaphysically unsettled: if it is open whether p is true, then it cannot currently be settled that p is true. So, open futurists—and libertarians who adopt the position—face the objection that their view makes rational action and deliberation impossible. I defuse the epistemic concern: open futurism does not entail obviously counterintuitive epistemic consequences or prevent rational action.

Argues that divine timelessness is at best irrelevant and at worst counterproductive for addressing the problem of foreknowledge and future contingents.

My topic is how to make decisions when you possess foreknowledge of the consequences of your choice. Many have thought that these kinds of decisions pose a distinctive and novel problem for causal decision theory (CDT). My thesis is that foreknowledge poses no new problems for CDT. Some of the purported problems are not problems. Others are problems, but they are not problems for CDT. Rather, they are problems for our theories of subjunctive supposition. Others are problems, but (...) they are not new problems. They are old problems transposed into a new key. Nonetheless, decisions made with foreknowledge illustrate important lessons about the instrumental value of our choices. Once we've appreciated these lessons, we are left with a version of CDT which faces no novel threats from foreknowledge. (shrink)

Critiques John Martin Fischer's bootstrapping model of divine foreknowledge. Invited contribution to a special journal issue on John Martin Fischer's _Our Fate: Essays on God and Free Will_ (Oxford, 2016).

Recently, several authors have utilized the notion of dependence to respond to the traditional argument for the incompatibility of freedom and divine foreknowledge. However, proponents of this response have not always been so clear in specifying where the incompatibility argument goes wrong, which has led to some unfounded objections to the response. We remedy this dialectical confusion by clarifying both the dependence response itself and its interaction with the standard incompatibility argument. Once these clarifications are made, it becomes clear (...) both (1.) that the dependence response does not beg the question against the proponent of the incompatibility argument and (2.) that the dependence response advances the dialectic whether it is developed as a version of Ockhamism or as a version of multiple-pasts compatibilism.

It is not uncommon to think that the existence of exhaustive and infallible divine foreknowledge uniquely threatens the existence of human freedom. This paper shows that this cannot be so. For, to uniquely threaten human freedom, infallible divine foreknowledge would have to make an essential contribution to an explanation for why our actions are not up to us. And infallible divine foreknowledge cannot do this. There remains, however, an important question about the compatibility of freedom and (...) class='Hi'>foreknowledge. It is a question not about the existence of foreknowledge, but about its mechanics. (shrink)

In this paper, I consider Augustine’s attempted solution of the problem of divine foreknowledge and free will. I focus on two distinct notions of God’s relationship to time as they relate to this problem. In Confessions XI, Augustine develops an understanding of time and foreknowledge that cIearly offers a possible solution to the foreknowledge/free will problem. I then turn to On Free Will 3.1-4, where Augustine conspicuously declines to use a solution similar to the one in the (...) Confessions, rather developing a response that demands a very different conception of foreknowledge. I subsequently argue that in On Free Will, Augustine’s argument requires that God’s foreknowledge, when considered in light of events involving human freedom, must be in a real sense dependent on the results of free choice.

A number of philosophers and theologians have argued that if God has knowledge of future human actions then human agents cannot be free. This argument rests on the assumption that, since God is essentially omniscient, God cannot be wrong about what human agents will do. It is this assumption that I challenge in this paper. My aim is to develop an interpretation of God’s essential omniscience according to which God can be wrong even though God never is wrong. If this (...) interpretation of essential omniscience is coherent, as I claim it is, then there is a logically consistent position according to which God is essentially omniscient, God foreknows what human agents will do, and yet it is possible for human agents to do otherwise. Thus, the argument for theological fatalism fails. (shrink)

I explore the motivation and logical consequences of the idea that we have some (limited) ability to know contingent facts about the future, even in presence of the assumption that the future is objectively unsettled or indeterminate. I start by formally characterizing skepticism about the future. This analysis nudges the anti-skeptic towards the idea that if some propositions about the future are objectively indeterminate, then it may be indeterminate whether a suitably positioned agent knows them. -/- Philosophical Perspectives, Volume 35, (...)

The dependence solution claims that God’s foreknowledge is no threat to our freedom because God’s foreknowledge depends (in a relevant sense) on our actions. The assumption here is that those parts of the world which depend on our actions are no threat to the freedom of those actions. Recently, Taylor Cyr has presented a case which challenges this assumption. Moreover, since the case is analogous to the case of God’s foreknowledge, it would seem to establish that, even (...) if God’s foreknowledge somehow depends on our actions, our freedom is still threatened. This paper defends the dependence solution, first, by offering an error theory for the intuitions that drive Cyr’s case and, second, by pointing out some arguably mysterious implications of accepting those intuitions. These points taken in conjunction show that Cyr’s case, although quite fascinating, is not as challenging as it might at first seem. (shrink)

John Martin Fischer has argued that Molinism does not constitute a response to the argument that divine foreknowledge is incompatible with human freedom. I argue that T. Ryan Byerly’s recent work on the mechanics of foreknowledge sheds light on this issue. It shows that Fischer’s claim is ambiguous, and that it may turn out to be false on at least one reading, but only if the Molinist can explain how God knows true counterfactuals of freedom.

I explore several issues raised in John Martin Fischer’s Our Fate: Essays on God and Free Will. First I discuss whether an approach to the problem of freedom and foreknowledge that appeals directly to the claim that God’s beliefs depend on the future is importantly different from Ockhamism. I suggest that this dependence approach has advantages over Ockhamism. I also argue that this approach gives us good reason to reject the claim that the past is fixed. Finally, I discuss (...) Fischer’s proposal regarding God’s knowledge of future contingents. I suggest that it may be able to secure comprehensive foreknowledge. (shrink)

We contend that since what is true cannot be false, foreknowledge is transparently incompatible with free will. We argue that what is crucial to the conflict is the role of truth in foreknowledge and that the identity of the one who foreknows is irrelevant.

Following an Open conception of Divine Foreknowledge, that holds that man is endowed with genuine freedom and so the future is not definitely determined, it will be claimed that human freedom does not limit the divine power, but rather enhances it and presents us with a barrier against arbitrary use of that power. This reading will be implemented to reconcile a well-known quarrel between two important interpreters of Duns Scotus, Allan B. Wolter and Thomas Williams, each of whom supports (...) a different interpretation of the way God acts according to right reason. (shrink)

In my "The Providential Advantage of Divine Foreknowledge" (2009) I respond to John Sanders' defense of the claim, made by many open theists, that foreknowledge of future contingents provides God with no providential advantage over a God who lacks such knowledge. William Hasker responded to that paper with a defense of Sanders, and the current paper is a response to Hasker's response.

If God knows everything he must know the future, and if he knows the future he must know the future acts of his creatures. But then his creatures must act as he knows they will act. How then can they be free? This dilemma has a long history in Christian philosophy and is now as hotly disputed as ever. The medieval scholastics were virtually unanimous in claiming both that God is omniscient and that humans have free will, though they disagreed (...) in their accounts of how the two are compatible. With the Reformation the debate became even more lively since there were Protestant philosophers who denied both claims, and many philosophers ever since have either thought it impossible to reconcile them or have thought it possible only because they weaken one or the other.

The article analyzes and criticizes the assumptions of Peter Van Inwagen’s argument for the alleged contradiction of the foreknowledge of God and human freedom. The argument is based on the sine qua non condition of human freedom defined as access to possible worlds containing such a continuation of the present in which the agent implements a different action than will be realized de facto in the future. The condition also contains that in every possible continuation of the present state (...) of affairs, the same propositions about the ‘present past’ (the past before the present moment) are true as are true in the present state of affairs. The paper argues that Van Inwagen’s reasoning is inconclusive, it contains the type of mistake of confusing conditional impossibility with unconditional and presents a methodologically wrong method of solving a philosophical problem. It is because in the very construction of the problem determining the available solution. The article points to the possibility that the human freedom of some action is not excluded by the fact that specific past facts logically entail that this event will occur. (shrink)

In this essay, my goal is, first, to describe the most important contemporary philosophical approaches to the nature of time, and then, secondly, to discuss the ways in which those different accounts bear upon the question of the possibility of divine foreknowledge.

Restating Augustinian Recipe to Divine Foreknowledge-Libertarian Freewill Dilemma and its Theodical Implications Abstract The divine foreknowledge-freewill dilemma has been the focus of much recent philosophico-theological discourse, even though the problem is centuries old. In the attempt to solve the dilemma, there have been some modifications on the traditional definition of divine foreknowledge. Some of the philosophical attempts to solve the dilemma include Molinism, Boethianism, Ochamism, Opentheism and others. While these attempts are noteworthy, their basic flaws lie in (...) their methodologies which involve a compromise of major orthodox theistic attributes and this compromise has a lot of theological implications. Contrarily, Augustine, in his attempt to solve the dilemma offered, a logical-based solution without taking recourse to a compromise of God’s foreknowledge in one hand, and libertarian-freewill on the other. Therefore, the researcher finds Augustine’s solution more plausible because it makes use of logical reasoning, biblical-support and because the Augustine’s solution to the Dilemma has a lot of implications to the contemporary discourse on Christian-theodicy. In view of this, the paper, using critical method, attempts to x-ray some of the attempts to solve the dilemma, points out their weaknesses and juxtapose them with that of Augustine, showing that Augustine’s solution is more logical. Finally the paper points out the theodical-utility of Augustine’s solution to orthodox-Christianity. (shrink)

In this paper I defend the eternity solution to the problem of human freedom and divine foreknowledge. After motivating the problem, I sketch the basic contours of the eternity solution. I then consider several objections which contend that the eternity solution falsely implies that we have various powers (e.g., to change God’s beliefs, or to affect the past) which, according to the objector, we do not in fact have.

One major aim of the book is to articulate a view of the mechanics of infallible divine foreknowledge that avoids commitment to causal determinism, explains how infallible foreknowledge is compatible with human freedom, and explains how God’s divine providence is compatible with human freedom and indeterministic events.

In fact, at critical moments when and are in question, we find very little detailed discussion.There is another epistemological goal in the book.

In a recent article, David Hunt has proposed a theological counterexample to the principle of alternative possibilities involving divine foreknowledge (G-scenario). Hunt claims that this example is immune to my criticism of regular Frankfurt-type counterexamples to that principle, as God’s foreknowing an agent’s act does not causally determine that act. Furthermore, he claims that the considerations which support the claim that the agent is morally responsible for his act in a Frankfurt-type scenario also hold in a G-scenario. In reply, (...) Icontest Hunt’s symmetry claim and also raise a worry whether, given theological fatalism, the agent’s act in a G-scenario can be deemed a free act in the libertarian sense. Finally, I offer an independent argument why in a G-scenario the agent should not regarded morally blameworthy for his act. (shrink)

After having given in the "Essay" a definition of freedom which straightforwardly entails its compatibility with – among other things – God's foreknowledge, Locke surprisingly writes in a 1693 letter to Molyneux that he does not see how human liberty can coexist with divine prescience.

Richard Swinburne recently released a paper titled, “Causation, Time and God’s Omniscience.” In this paper, Swinburne argued that God’s omniscience must be understood in a way that excludes divine foreknowledge. Swinburne deems this a necessary step in order to protect our freedom of the will. The purpose of my paper will be to refute Swinburne’s central argument. The goal of refuting Swinburne’s argument is to maintain the possibility of the compatibility of both divine foreknowledge and free human agency.

One of the major challenges in the philosophy of religion is theological fatalism—roughly, the claim that divine omniscience is incompatible with free will. In this article, I present new reasons to be skeptical of what I consider to be the strongest argument for theological fatalism. First, I argue that divine foreknowledge is not necessary for an argument against free will if we take into account divine knowledge of contingent a priori truths. Second, I show that this argument can be (...) generalized so that ordinary human knowledge of contingent a priori truths also leads to an argument against free will. This, I believe, results in an absurd conclusion that is unacceptable to both theists and non-theists. But if there is something wrong with this argument, there is something wrong, too, with the argument for theological fatalism. Although there is a range of possible responses, I suggest that the core issue in all cases is a closure principle—specifically, the principle that ‘no choice about’ is closed under entailment (or strict implication).

The Ockhamist claims that our ability to do otherwise is not endangered by God’s foreknowledge because facts about God’s past beliefs regarding future contingents are soft facts about the past—i.e., temporally relational facts that depend in some sense on what happens in the future. But if our freedom, given God’s foreknowledge, requires altering some fact about the past that is clearly a hard fact, then Ockhamism fails even if facts about God’s past beliefs are soft. Recent opponents of (...) Ockhamism, including David Widerker and Peter van Inwagen, have argued along precisely these lines. Their arguments, if successful, would undermine Ockhamism while avoiding the controversy over the alleged softness of facts about God’s past beliefs. But these arguments do not succeed. The past facts they rely on must be clear and uncontroversial examples of hard facts about the past, and these facts must be such that an ability to refrain from the relevant future action implies an ability to alter the relevant hard fact. We demonstrate the flaw in these arguments by showing how they rely on past facts that do not satisfy these criteria. The Ockhamist may have troubles, but this type of argument is not one of them.

Is Divine Knowledge Incompatible with Human Freedom? An Analysis of Some Arguments The problem that divine omniscience or divine foreknowledge makes free will impossible belongs to notoriously difficult to solve. In XX century one of the most important interpretation of this difficulty was provided by Nelson Pike. If God believes infallibly and in advance how Smith will act, this fact about the past excludes out all alternatives for Smith. But libertarian account of free will requires alternatives possibilities, so, it (...) could be argue that God’s foreknowledge is incompatible with our free will. This paper carefully criticizes Pike’s argumentation and suggests that because God’s foreknowledge doesn’t eliminate future alternatives through causal means, it is compatible with free will and that Pike’s argument and two briefly analyzed standard arguments for fatalism presented by Zagzebski failed.

Contemporary work on Boethius' Consolation of Philosophy often overlooks a discussion in CP.V.3 of a Peripatetic strategy for dissolving theological fatalism. Boethius’ treatment of this strategy and the lesson it provides about divine foreknowledge requires a reorientation of our understanding of the Consolation text. The result is that it is not foreknowledge nor any other temporally-conditioned knowledge that motivates Boethian concern but divine knowledge simpliciter.

In this paper we consider the possibility of a Quantum Molinism : such a view applies an analogue of the Molinistic account of free will‘s compatibility with God’s foreknowledge to God’s knowledge of (supposedly) indeterministic events at a quantum level. W e ask how (and why) a providential God could care for and know about a world with this kind of indeterminacy. We consider various formulations of such a Quantum Molinism, and after rejecting a number of options arrive at (...) one seemingly coherent formulation. (shrink)

Paper on divine foreknowledge and human freedom.

L’Exercitium academicum circa praescientiam daemonum (1666), pubblicato nella riformata Jena, tematizza una questione dibattuta nella Scolastica fra XIII e XIV secolo ma le cui radici risalgono ad Agostino d'Ippona, cui si deve il primo testo sull'argomento: la prescienza dei demoni. L'analisi segue la traccia del De divinatione daemonum agostiniano, mentre appare critica nei confronti delle posizioni di Tommaso d'Aquino e dei tomisti. Ad esse, in particolare riguardo alla natura delle facoltà intellettive demoniche, egli contrappone Giovanni Duns Scoto, Durando di san (...) Porziano e non meglio specificati nominales, accomunati in un indistinto riferimento alla teoria delle species. Ciò non toglie che il testo segua poi Tommaso nell'articolazione delle forme di prescienza dei demoni e nella definizione di questa come conoscenza congetturale. Scopo del nostro intervento sarà infatti mostrare, attraverso l'analisi che per la prima volta sarà condotta sul testo, lo spaccato di una comunità conversazionale nella quale le linee di forza e le distinzioni che animano il dibattito si mostrano autonome rispetto alle posizioni storiche di cattolici e riformati. Nell’Exercitium, Duns Scoto è contrapposto ai tomisti e, con Agostino e Durando di san Porziano – che costituisce una fonte comune del dibattito secentesco insieme a Bonaventura, Aureolo, Suarez, Vazquez, Gregorio di Valencia, e in tale veste sarà ripreso di lì a poco da Leibniz -, è cooptato tra gli autori a sostegno della sua tesi. Lungi dall'essere un esercizio di eclettismo o la stanca ripetizione di formule scolastiche, lo scritto getta luce su un dibattito universitario nel quale le fonti sono usate non come auctoritates ma quale repertorio di teorie da smontare e rimontare; ad esse l’Exercitium attinge per soluzioni che si definiscono in relazione a finalità filosofiche o dottrinali, ma non politiche né confessionali.

Boethius' conception of divine foreknowledge in his commentary on De interpretatione and the Consolation of philosophy. The author defends that the theological point of view is already present in De int. He also provides some texts by Augustine which signify an alternative Christian inspiration for the Neoplatonic philosophical principles that Boethius uses.

The topic of the paper is the role of assensus, and consequently of divine and human will, in Walter Chatton’s theory of prophecy (Reportatio super Sententias I, dd. 39-41). Starting from the question “how God knows the future contingents?”, the first step will be to consider Chatton’s analysis of Scotus’s voluntarism in the light of the concept of divine assensus, meaning as a model for the prophet’s will and, more generally, for the human wills. The paper will then focus on (...) the role of assensus in the act whereby which a truth is being revealed to the prophet; it is described as a sort of “induced” assent, where the will is bypassed and so, paradoxically, “unwilling”. Finally, the role of the will returns to be crucial on a third level, namely the viator’s assent to the prophetic statements, where assensus makes freedom of will possible, consistent with the divine foreknowledge, avoiding the danger of deterministic consequences.

An increasingly popular approach to reconciling divine foreknowledge with human freedom is to say that, because God’s beliefs depend on what we do, we are free to do otherwise than what we actually do despite God’s infallible foreknowledge. This paper develops a new challenge for this dependence response. The challenge stems from a case of backward time travel in which an agent intuitively lacks the freedom to do otherwise because of the time-traveler’s knowledge of what the agent will (...) do, and this is so despite the fact that the time-traveler’s knowledge depends on what the agent will do.

At least since Aristotle’s famous 'sea-battle' passages in On Interpretation 9, some substantial minority of philosophers has been attracted to the doctrine of the open future--the doctrine that future contingent statements are not true. But, prima facie, such views seem inconsistent with the following intuition: if something has happened, then (looking back) it was the case that it would happen. How can it be that, looking forwards, it isn’t true that there will be a sea battle, while also being true (...) that, looking backwards, it was the case that there would be a sea battle? This tension forms, in large part, what might be called the problem of future contingents. A dominant trend in temporal logic and semantic theorizing about future contingents seeks to validate both intuitions. Theorists in this tradition--including some interpretations of Aristotle, but paradigmatically, Thomason (1970), as well as more recent developments in Belnap, et. al (2001) and MacFarlane (2003, 2014)--have argued that the apparent tension between the intuitions is in fact merely apparent. In short, such theorists seek to maintain both of the following two theses: (i) the open future: Future contingents are not true, and (ii) retro-closure: From the fact that something is true, it follows that it was the case that it would be true. It is well-known that reflection on the problem of future contingents has in many ways been inspired by importantly parallel issues regarding divine foreknowledge and indeterminism. In this paper, we take up this perspective, and ask what accepting both the open future and retro-closure predicts about omniscience. When we theorize about a perfect knower, we are theorizing about what an ideal agent ought to believe. Our contention is that there isn’t an acceptable view of ideally rational belief given the assumptions of the open future and retro-closure, and thus this casts doubt on the conjunction of those assumptions.
