It is generally thought that objective chances for particular events different from 1 and 0 and determinism are incompatible. However, there are important scientific theories whose laws are deterministic but which also assign non-trivial probabilities to events. The most important of these is statistical mechanics whose probabilities are essential to the explanations of thermodynamic phenomena. These probabilities are often construed as 'ignorance' probabilities representing our lack of knowledge concerning the microstate. I argue that this construal is incompatible with the (...) role of probability in explanation and laws. This is the 'paradox of deterministic probabilities'. After surveying the usual list of accounts of objective chance and finding them inadequate I argue that an account of chance sketched by David Lewis can be modified to solve the paradox of deterministic probabilities and provide an adequate account of the probabilities in deterministic theories like statistical mechanics.

Adams presents an in-depth interpretation of three important parts of Leibniz's metaphysics, thoroughly grounded in the texts as well as in philosophical analysis and critique. The three areas discussed are the metaphysical part of Leibniz's philosophy of logic, his essentially theological treatment of the central issues of ontology, and his theory of substance. Adams' work helps make sense of one of the great classic systems of modern philosophy.

Strong nativist views about numerical concepts claim that human beings have at least some innate precise numerical representations. Weak nativist views claim only that humans, like other animals, possess an innate system for representing approximate numerical quantity. We present a new strong nativist model of the origins of numerical concepts and defend the strong nativist approach against recent cross-cultural studies that have been interpreted to show that precise numerical concepts are dependent on language and that they are restricted to speakers (...) of languages with the right kind of structure.

Rational agents face choices, even when taking seriously the possibility of determinism. Rational agents also follow the advice of Causal Decision Theory (CDT). Although many take these claims to be well-motivated, there is growing pressure to reject one of them, as CDT seems to go badly wrong in some deterministic cases. We argue that deterministic cases do not undermine a counterfactual model of rational deliberation, which is characteristic of CDT. Rather, they force us to distinguish between counterfactuals that are (...) relevant and ones that are irrelevant for the purposes of deliberation. We incorporate this distinction into decision theory to develop ‘Selective Causal Decision Theory’, which delivers the correct recommendations in deterministic cases while respecting the key motivations behind CDT.

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

Can there be deterministic chance? That is, can there be objective chance values other than 0 or 1, in a deterministic world? I will argue that the answer is no. In a deterministic world, the only function that can play the role of chance is one that outputs just Os and 1s. The role of chance involves connections from chance to credence, possibility, time, intrinsicness, lawhood, and causation. These connections do not allow for deterministic chance.

Bobzien presents the definitive study of one of the most interesting intellectual legacies of the ancient Greeks: the Stoic theory of causal determinism. She explains what it was, how the Stoics justified it, and how it relates to their views on possibility, action, freedom, moral responsibility, moral character, fatalism, logical determinism and many other topics. She demonstrates the considerable philosophical richness and power that these ideas retain today.

It is often called “the problem of free will and determinism,” as if the only thing that might challenge free will is determinism and as if determinism is obviously a problem. The traditional debates about free will have proceeded accordingly. Typically, incompatibilists about free will and determinism suggest that their position is intuitive or commonsensical, such that compatibilists have the burden of showing how, despite appearances, the problem of determinism is not really a problem. Compatibilists, (...) in turn, tend to proceed as if showing that determinism is not a problem thereby shows that we have free will, as if determinism is the only thing that might threaten free will. In this chapter, I reject both of these elements of the traditional debate; the question of whether we have free will should neither begin nor end with the so-called problem of determinism. I present and discuss evidence from a variety of studies that suggests that incompatibilism is not particularly intuitive. Most people do not have to be talked out of incompatibilism but rather talked into it. This provides some reasons—though certainly not decisive reasons—to think that compatibilism is true. I conclude by pointing out that, even if compatibilism were true, it would not dissolve the problem of free will, because there are problems other than determinism that need to be confronted—namely, challenges to free will suggested by current and “future science,” including neuroscience and psychology. The threats to free will suggested by these sciences are distinct from the traditional threat of determinism, and they are the ones that “ordinary persons” find intuitively threatening to free will. In fact, I will argue that the reason incompatibilism about free will and determinism appears to be intuitive is that determinism is often and easily misunderstood to involve these distinct threats to free will—threats that suggest that our rational, conscious mental activity is bypassed in the process of our making decisions and coming to act.

Some have argued that chance and determinism are compatible in order to account for the objectivity of probabilities in theories that are compatible with determinism, like Classical Statistical Mechanics (CSM) and Evolutionary Theory (ET). Contrarily, some have argued that chance and determinism are incompatible, and so such probabilities are subjective. In this paper, I argue that both of these positions are unsatisfactory. I argue that the probabilities of theories like CSM and ET are not chances, but also (...) that they are not subjective probabilities either. Rather, they are a third type of probability, which I call counterfactual probability. The main distinguishing feature of counterfactual-probability is the role it plays in conveying important counterfactual information in explanations. This distinguishes counterfactual probability from chance as a second concept of objective probability. (shrink)

I sketch a new constraint on chance, which connects chance ascriptions closely with ascriptions of ability, and more specifically with 'CAN'-claims. This connection between chance and ability has some claim to be a platitude; moreover, it exposes the debate over deterministic chance to the extensive literature on (in)compatibilism about free will. The upshot is that a prima facie case for the tenability of deterministic chance can be made. But the main thrust of the paper is to draw attention to the (...) connection between the truth conditions of sentences involving 'CAN' and 'CHANCE', and argue for the context sensitivity of each term. Awareness of this context sensitivity has consequences for the evaluation of particular philosophical arguments for (in) compatibilism when they are presented in particular contexts. (shrink)

A strongly deterministic theory of physics is one that permits exactly one possible history of the universe. In the words of Penrose (1989), "it is not just a matter of the future being determined by the past; the entire history of the universe is fixed, according to some precise mathematical scheme, for all time.” Such an extraordinary feature may appear unattainable in any realistic and simple theory of physics. In this paper, I propose a definition of strong determinism and (...) contrast it with those of standard determinism and super-determinism. Next, I discuss its consequences for explanation, causation, prediction, fundamental properties, free will, and modality. Finally, I present the first example of a realistic, simple, and strongly deterministic physical theory--the Everettian Wentaculus. As a consequence of physical laws, the history of the Everettian multiverse could not have been different. If the Everettian Wentaculus is empirically equivalent to other quantum theories, we can never empirically find out whether or not our world is strongly deterministic. Even if strong determinism fails to be true, it is closer to the actual world than we have presumed, with implications for some of the central topics in philosophy and foundations of physics.

Physicists are increasingly beginning to take seriously the possibility of laws outside the traditional time-evolution paradigm; yet many popular definitions of determinism are still predicated on a time-evolution picture, making them manifestly unsuited to the diverse range of research programmes in modern physics. In this article, we use a constraint-based framework to set out a generalization of determinism which does not presuppose temporal evolution, distinguishing between strong, weak and delocalised holistic determinism. We discuss some interesting consequences of (...) these generalized notions of determinism, and we show that this approach sheds new light on the long-standing debate surrounding the nature of objective chance.

This volume unites established authors and rising young voices in philosophical theology and philosophy of religion to offer the single most wide-ranging examination of theological determinism-in terms of both authors represented and issues investigated-published to date. Fifteen contributors present discussions about theological determinism, the view that God determines everything that occurs in the world. Some authors provide arguments in favor of this position, while others provide considerations against it. Many contributors investigate the relationship between theological determinism and (...) other philosophical issues, theological doctrines, or moral attitudes and practices. This book is essential reading for all those interested in the relationship between theological determinism and philosophical thought. (shrink)

This monograph deals with the controversy about determinism versus freedom of will. The book is addressed to scholars, especially in the areas of philosophy and psychology, and also to thinking and serious-minded laypersons who are interested in the implications of being human. The book attempts to help the reader understand and resolve the dilemma of determinism. The solution offered by this book has not been previously offered by any other book, even though the literature on this topic is (...) vast. The deterministic position is that all events are effects of previous events and causes of future events, in inexorable cause-effect sequences, which leave no room for intervention of anything outside of the stream of causal relationships, such as free will, thus rendering moral responsibility meaningless. Libertarians believe in freedom of will which is, for them, indispensable for moral responsibility. This controversy can be resolved only by making a clear distinction between two kinds of freedom. In common parlance, freedom means freedom from constraint or compulsion, which can be designated as contra-constraintual freedom. The second meaning of freedom is freedom from causation, which has been referred to as contra-causal freedom, and this is the meaning that is inherent in the concept of freedom of will. If we have contra-causal freedom, we can choose or decide to act irrespective of antecedent conditions including our own past. The distinction between contra-causal freedom and contra-constraintual freedom is the key to the resolution of the controversy between determinism and libertarianism. The absence of contra-causal freedom prevails at the theoretical, conceptual, objective, abstract, or as-is level, whereas contra-constraintual freedom functions at the practical, behavioral, subjective, concrete, or as-if level. All we need for moral responsibility is contra-constraintual freedom, and not contra-causal freedom. At the as-is level, there is neither freedom nor dignity, neither morality nor accountability, and neither purpose nor meaning for human existence. It is only at the as-if level that these terms make any sense at all. In theory there is no choice from alternative courses of action in light of the absence of contra-causal freedom; in practice there is, in direct proportion to contra-constraintual freedom. (shrink)

This volume examines Diderot's and d'Holbach's views on determinism to illuminate some of the most important debates taking place in eighteenth-century Europe. It problematises their atheism by showing their philosophy to be deeply rooted in the Christian tradition and provides a more nuanced and historicised interpretation of the so-called 'Radical Enlightenment', challenging the notions that this movement can be taken to be a perfectly coherent set of ideas and that it represents a complete break with 'the old'.

Originally published in 1934, this book presents the content of an inaugural lecture delivered by the British philosopher Charles Dunbar Broad (1887-1971), upon taking up the position of Knightbridge Professor of Moral Philosophy at Cambridge University. The text presents a discussion of the relationship between determinism, indeterminism and libertarianism. This book will be of value to anyone with an interest in the writings of Broad and the history of philosophy.

The hole argument contends that a substantivalist has to view General Relativity as an indeterministic theory. A recent form of substantivalist reply to the hole argument has urged the substantivalist to identify qualitatively isomorphic possible worlds. Gordon Belot has argued that this form of substantivalism is unable to capture other genuine violations of determinism. This paper argues that Belot's alleged examples of indeterminism should not be seen as a violation of a form of determinism that physicists are interested (...) in. What is undetermined in these examples, and in the hole argument, is a haecceitistic feature of the world. It is argued that these features are not among those we should expect the physical state of the world to determine. This vindicates the substantivalist reply to the hole argument, but also illustrates that philosophers of physics cannot ignore metaphysics when characterizing determinism for a physical theory.

This article illustrates in which sense genetic determinism is still part of the contemporary interactionist consensus in medicine. Three dimensions of this consensus are discussed: kinds of causes, a continuum of traits ranging from monogenetic diseases to car accidents, and different kinds of determination due to different norms of reaction. On this basis, this article explicates in which sense the interactionist consensus presupposes the innate?acquired distinction. After a descriptive Part 1, Part 2 reviews why the innate?acquired distinction is under (...) attack in contemporary philosophy of biology. Three arguments are then presented to provide a limited and pragmatic defense of the distinction: an epistemic, a conceptual, and a historical argument. If interpreted in a certain manner, and if the pragmatic goals of prevention and treatment are taken into account, then the innate?acquired distinction can be a useful epistemic tool. It can help, first, to understand that genetic determination does not mean fatalism, and, second, to maintain a system of checks and balances in the continuing nature?nurture debates. (shrink)

Determinism, Freedom, and Moral Responsibility brings together nine substantial essays on determinism, freedom, and moral responsibility in antiquity by Susanne Bobzien. The essays present the main ancient theories on these subjects, ranging historically from Aristotle followed by the Epicureans, the early Stoics, several later Stoics, and up to Alexander of Aphrodisias in the third century CE. -/- The author discusses questions about rational and autonomous human agency and their compatibility with a large range of important philosophical issues, including (...) their compatibility with divine predetermination and other theological questions; with atomism and continuum theory and with the physical sciences more generally; with the determination of character and its development from childhood through nature and nurture; with epistemic features such as ignorance of circumstances; with theories of necessity, possibility and contingency; with external or internal preceding causes and impediments; and with folk theories of fatalism. Room is also given to the questions of how human autonomous agency is related to moral development, to virtue and wisdom, and to blame and praise. -/- Historically unified, philosophically profound, and methodologically rigorous, Bobzien’s essays show that in Classical and Hellenistic philosophy these topics were all debated without reference to freedom to do otherwise or to a free will, and that the latter two notions were fully developed only later. The volume will be of interest both to philosophers and to historians of philosophy, with more than half of the essays accessible to advanced undergraduates. (shrink)

This book casts new light on the classic dispute between `compatibilists' and `incompatibilists' about determinism and moral responsibility. Martha Klein argues that the traditional account of the dispute, turning as it does on the notion of the agent's `ability to have acted otherwise',misrepresents the real disagreement, which arises from the compatibilists' conviction that it is sufficient for blameworthiness that an agent's wrongdoing was the result of a morally reprehensible frame of mind, and the incompatibilists' insistence that wrongdoers cannot be (...) morally responsible fortheir actions if they are not responsible for their motivating desires and beliefs. The incompatibilist position seems compelling when, for instance, we consider wrongdoers whose desires and attitudes can be traced to early emotional deprivation. The author argues that our response to these andother `problem cases' commits us to an incompatibilist condition for blameworthiness which is actually unfulfillable. In her view, however, some reflections on emotional deprivation should also encourage acceptance of a compatibilist condition which will satisfy our desire to be just more fully thanthe usual proposals emanating from either side of the debate.

This book examines the way in which new discoveries about genetic and neuroscience are influencing our understanding of human behaviour. As scientists unravel more about the ways in which genes and the environment work together to shape the development of our brains, their studies have importance beyond the narrow confines of the laboratory. This emerging knowledge has implications for our notions of morality and criminal responsibility. The extent to which "biological determinism" can be used as an explanation for our (...) behaviour is of interest to philosophers reflecting on the free will versus determinism debate. It also has repercussions for the criminal justice system; in courtrooms around the world, defence lawyers are beginning to appeal to genetic and brain imaging data as grounds for finding their clients not guilty. Can a defendant's genes or the structure of his brain be used as an excuse for his behaviour? Is criminality "hardwired"? Is it legitimate to claim "I couldn't help it, my genes made me do it"? This book appeals to anyone interested in the link between behaviour and genetics, the science and philosophy of moral responsibility and/or criminal law. (shrink)

The hole argument concludes that substantivalism about spacetime entails the radical indeterminism of the general theory of relativity (GR). In this paper, I amend and defend a response to the hole argument first proposed by Butterfield (1989) that relies on the idea of counterpart substantivalism. My amendment clarifies and develops the metaphysical presuppositions of counterpart substantivalism and its relation to various definitions of determinism. My defence consists of two claims. First, contra Weatherall (2018) and others: the hole argument is (...) not a blunder resulting from a mistaken view on how mathematical physics works, and requires a developed (meta)metaphysical response. Second, contra Melia (1999) and others: one can be content with a notion of determinism for GR which is not sensitive to merely haecceitistic differences. (shrink)

This article focuses on three themes concerning determinism and indeterminism. The first theme is observational equivalence between deterministic and indeterministic models. Here I discuss several results about observational equivalence and present an argument on how to choose between deterministic and indeterministic models involving indirect evidence. The second theme is whether Newtonian physics is indeterministic. I argue that the answer depends on what one takes Newtonian mechanics to be, and I highlight how contemporary debates on this issue differ from those (...) in the nineteenth century. The third major theme is how the method of arbitrary functions can be used to make sense of deterministic probabilities. I discuss various ways of interpreting the initial probability distributions and argue that they are best understood as physical, biological etc. quantities characterising the particular situation at hand. Also, I emphasise that the method of arbitrary functions deserves more attention than it has received so far. (shrink)

Legendary since his own time as a universal genius, Gottfried Wilhelm Leibniz (1646-1716) contributed significantly to almost every branch of learning. One of the creators of modern mathematics, and probably the most sophisticated logician between the Middle Ages and Frege, as well as a pioneer of ecumenical theology, he also wrote extensively on such diverse subjects as history, geology, and physics. But the part of his work that is most studied today is probably his writings in metaphysics, which have been (...) the focus of particularly lively philosophical discussion in the last twenty years or so. The writings contain one of the great classic systems of modern philosophy, but the system must be pieced together from a vast and miscellaneous array of manuscripts, letters, articles, and books, in a way that makes especially strenuous demands on scholarship. This book presents an in-depth interpretation of three important parts of Leibniz's metaphysics, thoroughly grounded in the texts as well as in philosophical analysis and critique. The three areas discussed are the metaphysical part of Leibniz's philosophy of logic, his essentially theological treatment of the central issues of ontology, and his theory of substance (the famous theory of monads).

I argue that there are non-trivial objective chances (that is, objective chances other than 0 and 1) even in deterministic worlds. The argument is straightforward. I observe that there are probabilistic special scientific laws even in deterministic worlds. These laws project non-trivial probabilities for the events that they concern. And these probabilities play the chance role and so should be regarded as chances as opposed, for example, to epistemic probabilities or credences. The supposition of non-trivial deterministic chances might seem to (...) land us in contradiction. The fundamental laws of deterministic worlds project trivial probabilities for the very same events that are assigned non-trivial probabilities by the special scientific laws. I argue that any appearance of tension is dissolved by recognition of the level-relativity of chances. There is therefore no obstacle to accepting non-trivial chance-role-playing deterministic probabilities as genuine chances. (shrink)

A previously unrecognised argument against deterministic chance is introduced. The argument rests on the twin ideas that determined outcomes are settled, while chancy outcomes are unsettled, thus making cases of determined but chancy outcomes impossible. Closer attention to tacit assumptions about settledness makes available some principled lines of resistance to the argument for compatibilists about chance and determinism. Yet the costs of maintaining compatibilism may be higher with respect to this argument than with respect to existing incompatibilist arguments.

This paper provides articulates a non-epiphenomenal, libertarian kind of free will—a kind of free will that’s incompatible with both determinism and epiphenomenalism—and responds to scientific arguments against the existence of this sort of freedom. In other words, the paper argues that we don’t have any good empirical scientific reason to believe that human beings don’t possess a non-epiphenomenal, libertarian sort of free will.

It has been argued that in a deterministic universe, no one has any reason to do anything. Since we ought to do what we have most reason to do, no one ought to do anything either. Firstly, it is argued that an agent cannot have reason to do anything unless she can do otherwise; secondly, that the relevant ‘can’ is incompatibilist. In this paper, I argue that even if the first step of the argument for reason incompatibilism succeeds, the second (...) one does not. It is argued that reasons require alternative possibilities, because reasons are action-guiding. A supposed reason to do the impossible, or to do what was inevitable anyway, could not fill this function. I discuss different interpretations of the claim that reasons are action-guiding, and show that according to one interpretation it is sufficient that the agent believes that she has several alternative options. According to other interpretations, the agent must really have alternative options, but only in a compatibilist sense. I suggest that an interpretation of action-guidance according to which reasons can only guide actions when we have several options open to us in an incompatibilist sense cannot be found. We should therefore assume that reasons and obligations are compatible with determinism. (shrink)

We clarify the status of the so-called causal minimality condition in the theory of causal Bayesian networks, which has received much attention in the recent literature on the epistemology of causation. In doing so, we argue that the condition is well motivated in the interventionist (or manipulability) account of causation, assuming the causal Markov condition which is essential to the semantics of causal Bayesian networks. Our argument has two parts. First, we show that the causal minimality condition, rather than an (...) add-on methodological assumption of simplicity, necessarily follows from the substantive interventionist theses, provided that the actual probability distribution is strictly positive. Second, we demonstrate that the causal minimality condition can fail when the actual probability distribution is not positive, as is the case in the presence of deterministic relationships. But we argue that the interventionist account still entails a pragmatic justification of the causal minimality condition. Our argument in the second part exemplifies a general perspective that we think commendable: when evaluating methods for inferring causal structures and their underlying assumptions, it is relevant to consider how the inferred causal structure will be subsequently used for counterfactual reasoning.

The studies we report indicate that it is possible to manipulate explicit ascriptions of consciousness by manipulating whether an agent’s behavior is deterministically caused. In addition, we explore whether this impact of determinism on consciousness is direct, or mediated by notions linked to agency – notions like moral responsibility, free will, deliberate choice, and sensitivity to moral reasons. We provide evidence of mediation. This result extends work on attributions of consciousness and their connection to attributions of agency by Adam (...) Arico, Brian Fiala, and Shaun Nichols (Arico et al. 2011, Fiala et al. 2014) and supports it against recent criticisms (e.g., Sytsma 2014). (shrink)

On the face of it ‘deterministic chance’ is an oxymoron: either an event is chancy or deterministic, but not both. Nevertheless, the world is rife with events that seem to be exactly that: chancy and deterministic at once. Simple gambling devices like coins and dice are cases in point. On the one hand they are governed by deterministic laws – the laws of classical mechanics – and hence given the initial condition of, say, a coin toss it is determined whether (...) it will land heads or tails.2 On the other hand, we commonly assign probabilities to the different outcomes a coin toss, and doing so has proven successful in guiding our actions. The same dilemma also emerges in less mundane contexts. Classical statistical mechanics (which is still an important part of modern physics) assigns probabilities to the occurrence of certain events – for instance to the spreading of a gas that is originally confined to the left half of a container – but at the same time assumes that the relevant systems are deterministic. How can this apparent conflict be resolved? (shrink)

A deterministic model that accounts for the statistical behavior of random samples of identical particles is presented. The model is based on some nonmeasurable distribution of spin values in all directions. The mathematical existence of such distributions is proved by set-theoretical techniques, and the relation between these distributions and observed frequencies is explored within an appropriate extension of probability theory. The relation between quantum mechanics and the model is specified. The model is shown to be consistent with known polarization phenomena (...) and the existence of macroscopic magnetism. Finally..

Divine determinism, though affirmed by many Calvinists, implicates God in the decisions people make that ultimately damn them to the terrible destiny of hell. In this paper, the authors argue that this scenario is a problem for divine determinism. The article contends that determinism is inconsistent with God’s love and the Scriptures that explicitly state that God does not ‘desire’ anyone to go to hell. Even human love for others strongly suggests that God, who is ‘love’, will (...) not determine anyone to hell. On the other extreme, those who argue for universalism, though appealing to Scripture, often do so with questionable exegesis. (shrink)

While standard procedures of causal reasoning as procedures analyzing causal Bayesian networks are custom-built for (non-deterministic) probabilistic struc- tures, this paper introduces a Boolean procedure that uncovers deterministic causal structures. Contrary to existing Boolean methodologies, the procedure advanced here successfully analyzes structures of arbitrary complexity. It roughly involves three parts: first, deterministic dependencies are identified in the data; second, these dependencies are suitably minimalized in order to eliminate redundancies; and third, one or—in case of ambiguities—more than one causal structure is (...) assigned to the minimalized deterministic dependencies.

The proper limit to paternalist regulation of citizens' private lives is a recurring theme in political theory and ethics. In the present study, we examine the role of beliefs about free will and determinism in attitudes toward libertarian versus paternalist policies. Throughout five studies we find that a scientific deterministic worldview reduces opposition toward paternalist policies, independent of the putative influence of political ideology. We suggest that exposure to scientific explanations for patterns in human behavior challenges the notion of (...) personal autonomy and, in turn, undermines libertarian arguments against state paternalism appealing to autonomy and personal choice.

The indirect argument (IA) for incompatibilism is based on the principle that an action to which there is no alternative is unfree, which we shall call ‘PA’. According to PA, to freely perform an action A, it must not be the case that one has ‘no choice’ but to perform A. The libertarian and hard determinist advocates of PA must deny that free will would exist in a deterministic world, since no agent in such a world would perform an action (...) to which there were alternatives: an action there being the necessary consequence of preceding events and the laws of nature, it would not be possible for a person to perform actions besides those he actually performs. Determinism is seen here as “indirectly” ruling out free will by making the satisfaction of a necessary condition of free agency impossible, the former requiring, according to the leading proponent of libertarianism, Robert Kane, the performance of free actions. To have a free will, on his view, is to have committed “self-forming” actions, that is, to have done things to which there were alternatives the doing of which led to the development of the desires, preferences, and beliefs that make up one’s character. -/- The range of phenomena obeying probabilistic laws has yet to be ascertained. Under certain assumptions, both STR and GTR entail an indeterministic mechanics. But, contrary what is often claimed, quanta do not behave indeterministicly: the wave function/probabilistic laws being necessary only insofar as we wish to macroscopicly describe their behavior. It is far less clear, however, that the macro-events involved in human decision making and behavior, such as the releasing of neurotransmitters and the contracting of muscles, occur indeterministically. The ontological status of these events-whether or not they are the necessary effects of prior occurrences-is, of course, what matters in the free will debate. For present purposes, however, this question will be put aside. Instead, I will concentrate on buttressing the existing case against PA, aiming to show that even if deterministic laws hold at the level of macro-phenomena, free will remains a possibility. That is to say, I shall defend the thesis that so-called “Frankfurt cases” demonstrate that alternatives are not required to perform an action that is free in the sense of being something for which its agent is responsible. -/- My defense will be carried out in three stages. First, I must respond to those who maintain that a Frankfurt case is not a counterexample to PA because it is not an example of someone acting without alternatives. Here, I confront the question of how “robust” an alternative must bein order to provide an agent with a way of avoiding praise or blame for the action that she actually commits. Secondly, I must show that an agent may be praiseworthy or blameworthy despite lacking alternatives at the time at which she acts, i.e., an appropriate object of one of a Strawsonian “reactive attitude” sans what I shall call “local” alternatives. At this point, I must attend to David Widerker’s recent critique of the use of Frankfurt cases as counterexamples to PA. Finally, I set for myself what I take to be the most difficult task of a compatibilist: demonstrating that not even an “historical” alternative-the possibility of having chosen a different path in life than the one that one has actually taken-is needed to have a free will. In this connection, it will be incumbent upon me to explain why it would be fair to hold someone accountable for behavior issuing from a self she did not create, dispositions originating from natural conditions she did not establish. That is to say, in denying that a free will entails the ability to transcend oneself, I shall be faced with what Kane calls the “ultimacy” problem: how to explain away the incompatibilist’s intuition that it is senseless to adopt a reactive attitude towards someone incapable of self-transcendence, even if such a reaction is itself unavoidable. By showing that the desire for self-transcendence is itself irrational, I intend to solve this problem. I will, thus, be left defending a version of compatibilism according to which a free will is to be understood as a healthy faculty-the will-being exercised in an environment conducive to self-realization, which is its purpose.

The Consequence argument is an argument from plausible premises–our lack of causal power over the laws and past–to an implausible conclusion: that if determinism is true, we are equally powerless with respect to the future. What the compatibilist needs is a theory of counterfactuals that preserves the links between counterfactuals, causation, and the natural laws in a way that supports our commonsense belief that we have the power to make a causal difference to the future but no such power (...) with respect to the past. Lewis’s critique of the Consequence argument was based on his theory of counterfactuals and his analysis of causation as a counterfactual relation between particular events. He argued that, at a world that is deterministic in the way that ours might be, counterfactuals are temporally asymmetric in a way that matches the contingent temporal asymmetry of cauation. So it is not surprising, but only to be expected, that the past is causally closed while the future is causally open. If this worked, it would be just what the compatibilist needs. But it doesn’t work. There is an argument, due to Tooley and recently endorsed by Wasserman, that a fundamental feature of Lewis’s theory of counterfactuals is inconsistent with the metaphysical possibility of time travel and backwards causation. If this is right, then Lewis’s response to the Consequence argument fails. I endorse this conclusion, but argue that there is a better theory of counterfactuals–a theory that leaves open the metaphysical possibility of time travel to the past and backwards causation.

In his Philosophical Inquiry concerning Human Liberty (1717), the English deist Anthony Collins proposed a complete determinist account of the human mind and action, partly inspired by his mentor Locke, but also by elements from Bayle, Leibniz and other Continental sources. It is a determinism which does not neglect the question of the specific status of the mind but rather seeks to provide a causal account of mental activity and volition in particular; it is a ‘volitional determinism’. Some (...) decades later, Diderot articulates a very similar determinism, which seeks to recognize the existence of “causes proper to man” (as he says in the Réfutation d’Helvétius). The difference with Collins is that now biological factors are being taken into account. Obviously both the ‘volitional’ and the ‘biological’ forms of determinism are noteworthy inasmuch as they change our picture of the nature of determinism itself, but my interest here is to compare these two determinist arguments, both of which are broadly Spinozist in nature – and as such belong to what Jonathan Israel called in his recent book “the radical Enlightenment,” i.e. a kind of underground Enlightenment constituted by Spinozism – and to see how Collins’ specifically psychological vision and Diderot’s specifically biological vision correspond to their two separate national contexts: determinism in France in the mid-1750s was a much more medico-biological affair than English determinism, which appears to be on a ‘path’ leading to Mill and associationist psychology.

I outline a heretofore neglected difference between manipulation scenarios and merely deterministic ones. Plausible scientific determinism does not imply that the relevant prior history of the universe is independent of us, while manipulation does. Owing to sensitive dependence of physical outcomes upon initial conditions, in order to trace a deterministic history, a microphysical level of analysis is required. But on this level physical laws are time-symmetrically deterministic, and causality, conceived asymmetrically, disappears. I then consider a revised scenario to resurrect (...) the threat of manipulation even in the presence of time-symmetry and sensitive dependence upon initial conditions. To do so we posit a manipulator containing all the information of the manipulated and time-symmetrically related to him. The new scenario violates special relativity, but even waiving that objection, the scenario faces a dilemma. I argue that the manipulator either lacks agency enough to manipulate the target, or can integrate thoughts separated by long time spans into a single decision. In the latter case, the 'manipulated agent' disappears into the manipulator, making it the story of just one agent. (shrink)

Twenty-first-century biology rejects genetic determinism, yet an exaggerated view of the power of genes in the making of bodies and minds remains a problem. What accounts for such tenacity? This article reports an exploratory study suggesting that the common reliance on Mendelian examples and concepts at the start of teaching in basic genetics is an eliminable source of support for determinism. Undergraduate students who attended a standard ‘Mendelian approach’ university course in introductory genetics on average showed no change (...) in their determinist views about genes. By contrast, students who attended an alternative course which, inspired by the work of a critic of early Mendelism, W. F. R. Weldon, replaced an emphasis on Mendel’s peas with an emphasis on developmental contexts and their role in bringing about phenotypic variability, were less determinist about genes by the end of teaching. Improvements in both the new Weldonian curriculum and the study design are in view for the future. (shrink)

The article puts forward a branching-style framework for the analysis of determinism and indeterminism of scientific theories, starting from the core idea that an indeterministic system is one whose present allows for more than one alternative possible future. We describe how a definition of determinism stated in terms of branching models supplements and improves current treatments of determinism of theories of physics. In these treatments, we identify three main approaches: one based on the study of equations, one (...) based on mappings between temporal realizations, and one based on branching models. We first give an overview of these approaches and show that current orthodoxy advocates a combination of the mapping- and the equations-based approaches. After giving a detailed formal explication of a branching-based definition of determinism, we consider three concrete applications and end with a formal comparison of the branching- and the mapping-based approach. We conclude that the branching-based definition of determinism most usefully combines formal clarity, connection with an underlying philosophical notion of determinism, and relevance for the practical assessment of theories. 1 Introduction2 Determinism in Philosophy of Science: Three Approaches2.1 Determinism: The core idea and how to spell it out2.2 The three approaches in more detail2.3 Representing indeterminism3 Orthodoxy: DMAP, with Invocations of DEQN4 Branching-Style Determinism 4.1 Models and realizations4.2 Faithfulness4.3 Two types of branching topologies 5 Comparing the Approaches5.1 Case studies5.2 Formal comparison of the DMAP and DBRN frameworks6 Conclusions.
