The classical determinist argument is that every event has a cause, that every event in the universe is an effect whose sufficient and necessary conditions are the state of the universe immediately preceding it. For this reason we could not have done otherwise than we did. We do not have free-wills and hence we are not morally responsible for our thoughts and actions. The classical deterministmay, however, modify his position and agree that not every event inthe world has a cause, (...) but only that every human activity—our thoughts and our actions—are causally determined. Butit would still follow that we could not have done otherwise than wedid. As the first formulation entails the second formulation, and is more usual, we shall adopt that one. (shrink)

The prediction of future events from our knowledge of past events is one of the main functions of Science. Such predictions are made possible by inferring causal relations between events from observed regularities. These relations are then codified into “laws of nature,” and it is through knowledge of these laws that prediction becomes possible. The concept of “causal relation” is thus a fundamental one in the structure of science. Now recent advances in physics have led scientists to modify (...) considerably their views of this concept. It has been found necessary to abandon the idea of rigidly deterministic causal relations, and substitute in its stead relations that are only determined with a certain degree of probability. The main purpose of this paper is to analyse the meaning of these changes in our concepts of causality. (shrink)

Education and Free Will critically assesses and makes use of Spinoza’s insights on human freedom to construe an account of education that is compatible with causal determinism without sacrificing the educational goal of increasing students’ autonomy and self-determination. Offering a thorough investigation into the philosophical position of causal determinism, Dahlbeck discusses Spinoza’s view of self-determination and presents his own suggestions for an education for autonomy from a causal determinist point of view. -/- The book begins (...) by outlining the free will problem in education, before expanding on a philosophical understanding of autonomy and how it is seen as an educational ideal. It considers Spinoza’s determinism and discusses his denial of moral responsibility. Later chapters consider the relationship between causal determinism and autonomy, the educational implications of understanding free will and how free will can be utilised as a valuable fiction in education. -/- This book will be of great interest to academics and postgraduate students in the field of education, especially those with an interest in moral education and philosophy of education. It will also be of interest to those in the fields of philosophy and psychology and specifically those focusing on the free will problem, on Spinoza studies, and on the relation between moral psychology and external influence.

This paper addresses the rift between the teacher’s sense of self as a causal agent and the experience of being in lack of control in the classroom, by way of Hans Vaihinger’s philosophy of ‘as if.’ It is argued that understanding agential control in terms of a valuable fiction—a practical fiction in Vaihinger’s vocabulary—can offer a way of bridging this rift and can help teachers make sense of the tension between their felt need to strive for control and their (...) experience of suffering from lack of control. A fiction, it is argued, is different from an illusion in that fictions can be affirmed without being believed. Unlike illusions, valuable fictions can be recognized as fictions and still retain some of their affective power over us, thereby allowing us to act ‘as if.’ In education, this is helpful as it means that we can make use of valuable fictions without assuming that these have to be protected from the critical gaze of non-believers. In fact, we can openly acknowledge that we rely on fictions as this is part and parcel of being a human being with a limited cognitive ability. (shrink)

Four studies explored people's judgments about whether particular types of behavior are compatible with determinism. Participants read a passage describing a deterministic universe, in which everything that happens is fully caused by whatever happened before it. They then assessed the degree to which different behaviors were possible in such a universe. Other participants evaluated the extent to which each of these behaviors had various features. We assessed the extent to which these features predicted judgments about whether the behaviors were (...) possible in a deterministic universe. Experiments 1 and 2 found that people's judgments about whether a behavior was compatible with determinism were not predicted by their judgments about whether that behavior relies on physical processes in the brain and body, is uniquely human, is unpredictable, or involves reasoning. Experiment 3, however, found that a distinction between what we call “active” and “passive” behaviors can explain people's judgments. Experiment 4 extended these findings, showing that we can measure this distinction in several ways and that it is robustly predicted by two different cues. Taken together, these results suggest that people carve up mentally guided behavior into two distinct types—understanding one type to be compatible with determinism, but another type to be fundamentally incompatible with determinism.

The classic formulation of causal decision theory (CDT) appeals to counterfactuals. It says that you should aim to choose an option that would have a good outcome, were you to choose it. However, this version of CDT faces trouble if the laws of nature are deterministic. After all, the standard theory of counterfactuals says that, if the laws are deterministic, then if anything—including the choice you make—were different in the present, either the laws would be violated or the distant (...) past would be changed. And as several authors have shown, it's easy to transform this upshot of the standard theory of counterfactuals into full-blown counterexamples to CDT. In response to these counterexamples, I argue here that the problem lies, not so much with CDT's guiding idea—that it's the expected causal consequences of your actions that matter for rational decision-making—but with the fact that the classic formulation of CDT doesn't pay sufficient attention to the context-sensitivity of counterfactuals. I develop a contextualist version of CDT which better accounts for this context-sensitivity. And I show that my theory avoids the problems faced by the classic formulation of CDT in determinstic worlds. (shrink)

La tesis principal de este ensayo estipula que el determinismo causal es una propiedad de la naturaleza y el primer principio de la inteligibilidad natural. Se expresa, por ejemplo, en la frase de Lucrecio: “Nada surge de la nada ni va hacia la nada”. Todo lo que existe es efecto de una red de causas y es a su vez causa de otras cosas. Se sigue que la teoría científica orientada hacia la inteligibilidad —diferente de la ciencia positi-vista y (...) pragmática— es la búsqueda de determinismo causal. El desarrollo de esta tesis utiliza como hilo conductor el pensamiento de René Thom. Esto significa que el determinismo causal se examina en su rela-ción con (I) la estabilidad y la inestabilidad, (II) el desafío de la mecánica cuántica, (III) las raíces aporéticas de la ciencia tal como la dualidad determinismo-indeterminismo, y finalmente (IV) en su relación con el método para ponerlo de manifiesto, es decir la reducción de lo posible —estrategia que es, en este dominio, una de las ideas más originales de Thom.The main thesis of this essay is that causal determinism is a property of nature and the main principle of natural intelligibility. It can be expressed in Lucretius’ words: “Nothing comes out of nothing or passes into nothing”. Everything is the effect of a web of causes and is, in its turn, cause of something else. It follows that the essence of an intelligibility-oriented scientific theory —which is different from science in a positivist or pragmatist sense— is the search for causal determinism. The development of this thesis is guided by René Thom’s thought. This means that causal determinism is analysed, first, in its relation to stability and instability; second, in its relation to the prima facie indeterminism of quantum mechanics; third, in its relation to the aporetic roots of science such as the duality determinism —indeterminism, and, finally, in its relation to the method which allows science to follow the causal determinist ideal: the reduction of the possible— a strategy which is, in this field, one of Thom’s most original ideas.

We have two main aims: to construct mathematical models for analysing determinism, causality and supervenience; and then to use these to demonstrate the possibility of constructing an ontic construal of the operation of free will - one requiring both the presentation of genuine alternatives to an agent and their selecting between them in a manner that permits the attribution of responsibility. Determinism is modelled using trans-temporal ontic links between discrete juxtaposed universe states and shown to be distinct from (...) predictability. Causality is defined on a temporal sequence of δ-algebras and quantified using a measure. The measure leads to definitions of causal overdetermination and epiphenomena. Proofs are constructed to demonstrate deterministic universes must carry their properties essentially but not necessarily locally. We argue determinism and causality are separate doctrines. These models and results are marshalled to put the case that a counterfactual construal of ontic choice cannot work. In response we propose ‘immanence’ - a modified form of indeterminism whereby a universe can present choices to its denizens. We prove that beings subsumed within a universe cannot pilot their own actions. We then argue these beings can exercise free will only when selecting between choices inhering within immanent relata. A being is responsible for its selections if and only if it is constituted of a temporally evolving deterministic substructure. Our proposal is novel: it avoids injecting indeterminism into the decision process. Topological models for property supervenience are developed and used to reconstruct standard definitions from the literature. These are then used to demonstrate considerations of supervenience do not affect our arguments. We have demonstrated that a model of the exercise of free will involving both genuine choices and responsibility is possible but can only operate within a non-deterministic universe possessing specific traits.

In the Transcendental Dialectic of the first Critique Kant sets forth the ancient problem of freedom and determinism by way of the Third Antinomy. The problem, according to Kant, arises out of a conflict of reason with itself as it seeks an unconditioned ground which will provide a unity for all conditions. In the thesis of the Third Antinomy reason sees the necessity of postulating a free causality “without which, even in the [ordinary] course of nature the series of (...) appearances on the side of the causes can never be complete.” On the other hand, in the antithesis, there is a denial of such transcendental freedom on the ground that it would undercut the unity of the work of the understanding so that “the appearances which in their natural course are regular and uniform would be reduced to disorder and incoherence.”.

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. (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.

Determinism, causality, chance, free will and divine providence form a class of interlaced problems lying in three domains: philosophy, theology, and physics. Recent article by Dariusz Łukasiewicz in Roczniki Filozoficzne (no. 3, 2020) is a great example. Classical physics, that of Newton and Laplace, may lead to deism: God created the world, but then it goes like a mechanical clock. Quantum mechanics brought some “hope” for a rather naïve theology: God acts in gaps between quanta of indetermination. Obviously, any (...) strict determinism jeopardizes the existence of free will. Yes, but only if human mind follows the laws of physics and only if nothing exists outside the physical limits of space and time. We argue that human action lies in-between two worlds: “earth” and “heavens” using the language of Genesis. In that immaterial world, outside time and space constraints, there is no place for the chain of deterministic events. We discuss, in turn, that the principle of causality, a superior law even in physics, reigns also in the non-material world. Though, determinism in the material universe and causality in both worlds seem to be sufficient conditions, to eliminate “chaotic”, or probabilistic causes from human (and divine) action. (shrink)

In this short piece of work, an attempt has been made to revisit the skepticism about free will, which has historically been directed to it due to certain mistaken assumptions about determinism and iron it out. Determinism is often conflated with fatalism, and this is where the skepticism about the possibility of agential autonomy and control begins. If fatalism is true with respect to volitional actions of agents, then there is no point in planning or choice making as (...) fatalism dissolves the idea of control. The main argument proposed in this work consists in showing that even though deterministic causation involves the possibility of a single unique outcome as a necessary consequence of the antecedent conditions and the governing laws of nature, the history of rational behaviour of every agent can be explained within a global deterministic kind of causal framework. If rightly interpreted, it provides a glimpse into how different courses of action remain feasibly open to an agent at a given time. The concept of free will has been outlined first to enable the reader to see later that looking at the doctrine of determinism with the right kind of mindset only reveals its pro-free will nature.

In the philosophical tradition, the notions of determinism and causality are strongly linked: it is assumed that in a world of deterministic laws, causality may be said to reign supreme; and in any world where the causality is strong enough, determinism must hold. I will show that these alleged linkages are based on mistakes, and in fact get things almost completely wrong. In a deterministic world that is anything like ours, there is no room for genuine causation. Though (...) there may be stable enough macro-level regularities to serve the purposes of human agents, the sense of “causality” that can be maintained is one that will at best satisfy Humeans and pragmatists, not causal fundamentalists.

The paper revisits the old controversy over causality and determinism and argues, in the first place, that non˗deterministic theories of modern science are largely irrelevant to the philosophical issue of the causality principle. As it seems to be the ‘moral’ of the uncertainty principle, the reason why a deterministic theory cannot be applied to the description of certain physical systems is that it is impossible to capture such properties of the system, which are required by a desired theory. These (...) properties constitute what is called ‘the state’ of a system. However, the notion of a state of a system is relative: it depends on a particular theory which one would like to use to describe given kinds of phenomena. This implies that, even in the case where the desired state of a system is fundamentally impossible to be captured, neither ontological nor epistemological determinism may be excluded. Some following critical considerations are also offered with regard to the claim that uncertainty is “rooted in the things themselves”. The cradle of modern discussions about causality and determinism is, of course, quantum mechanics. Because, as it appears, a judgment on deterministic or non˗deterministic character of a theory can be made only after some interpretation of this theory has been given, the paper briefly reminds some chosen interpretations of quantum mechanics (Schrödinger's, probabilistic, statistical, Copenhagen, and the interpretation of quantum ensembles). Many of such interpretations, offered in the past, have now been rejected, and some gained more credibility than the others. Nonetheless, even the claim that indeterminism is irremovable from the description of the micro-world doesn't imply the rejection of the most general formula of the philosophical causality principle. There is no direct implication between theses of the epistemology of scientific knowledge and those of the ontology of the real world. (shrink)

A previous paper of mine, that criticized Suppes' probabilistic theory of causality, was in turn criticized by Deborah Rosen. This paper is a development of my argument and an answer to Rosen. It is argued that the concept of causation is used in contemporary science in a way that presupposes determinism. It is shown that deterministic assumptions are necessary for inferences from generic to individual causal relations and for various kinds of eliminative arguments.

A primeira tese de Sober é que não podemos agir livremente, a não ser que o Argumento da Causalidade ou o Argumento da Inevitabilidade tenham alguma falha. O Argumento da Causalidade é o seguinte: nossos estados mentais causam movimentos corporais; mas nossos estados mentais são causados por fatores do mundo físico. Nossa personalidade pode ser reconduzida à nossa experiência e à nossa genética. E tanto a experiência quanto a genética foram causados por itens do mundo físico. Assim, o meio ambiente (...) e os genes são os causadores de nossas crenças e desejos. E estes, por sua vez, causam o nosso comportamento. Como, em última instância, não escolhemos nem os nossos genes e nem o meio ambiente no qual adquirimos as nossas experiências, também não escolhemos o nosso comportamento: ele é causado por fatores além do nosso controle; isso nos faz não ser livres. E o Argumento da Inevitabilidade é exposto por Sober assim: se uma ação foi praticada livremente, então deve ter sido possível ao agente agir de outra forma. Mas, dado que as causas de nossas ações são as nossas crenças e desejos, não poderíamos ter agido diferentemente de como elas nos determinam a agir. (shrink)

Carl Hempel (1965) argued that probabilistic hypotheses are limited in what they can explain. He contended that a hypothesis cannot explain why E is true if the hypothesis says that E has a probability less than 0.5. Wesley Salmon (1971, 1984, 1990, 1998) and Richard Jeffrey (1969) argued to the contrary, contending that P can explain why E is true even when P says that E’s probability is very low. This debate concerned noncontrastive explananda. Here, a view of contrastive (...) class='Hi'>causal explanation is described and defended. It provides a new limit on what probabilistic hypotheses can explain; the limitation is that P cannot explain why E is true rather than A if P assign E a probability that is less than or equal to the probability that P assigns to A. The view entails that a true deterministic theory and a true probabilistic theory that apply to the same explanandum partition are such that the deterministic theory explains all the true contrastive propositions constructable from that partition, whereas the probabilistic theory often fails to do so.

The present text comments on Steel 2005 , in which the author claims to extend from the deterministic to the general case, the result according to which the causal Markov condition is satisfied by systems with jointly independent exogenous variables. I show that Steel’s claim cannot be accepted unless one is prepared to abandon standard causal modeling terminology. Correlatively, I argue that the most fruitful aspect of Steel 2005 consists in a realist conception of error terms, and I (...) show how this conception sheds new light on the relationship between determinism and the causal Markov condition. †To contact the author, please write to: Institut Supérieur de Philosophie, Université Catholique de Louvain, Place du Cardinal Mercier 14, 1348 Louvain la Neuve, Belgium; e‐mail: [email protected].

Łukasiewicz and, more recently, other philosophers have cast doubts on arguments from one version of determinism to another: roughly, from the view that every event (condition, state) has a cause or is determined, to the view that the remotest possible past determines the present and future. This paper defends a special class of such arguments. It identifies constraints on the relation of determination under which the arguments concerned are valid. And, by reference to the overall causal or determinational (...) structure of the universe, it argues that the constraints themselves are highly plausible. (shrink)

It is commonly thought that before the introduction of quantum mechanics, determinism was a straightforward consequence of the laws of mechanics. However, around the nineteenth century, many physicists, for various reasons, did not regard determinism as a provable feature of physics. This is not to say that physicists in this period were not committed to determinism; there were some physicists who argued for fundamental indeterminism, but most were committed to determinism in some sense. However, for them, (...) determinism was often not a provable feature of physical theory, but rather an a priori principle or a methodological presupposition. Determinism was strongly connected with principles of causality and continuity and the principle of sufficient reason; this thesis examines the relevance of these principles in the history of physics. Moreover, the history of determinism in this period shows that there were essential changes in the relation between mathematics and physics: whereas in the eighteenth century, there were metaphysical arguments which lent support to differential calculus, by the early twentieth century the development of rigorous foundations of differential calculus led to concerns about its applicability in physics. The thesis consists of six papers. In the first paper, "On the origins and foundations of Laplacian determinism", I argue that Laplace, who is usually pointed out as the first major proponent of scientific determinism, did not derive his statement of determinism directly from the laws of mechanics; rather, his determinism has a background in eighteenth century Leibnizian metaphysics, and is ultimately based on the law of continuity and the principle of sufficient reason. These principles also provided a basis for the idea that one can find laws of nature in the form of differential equations which uniquely determine natural processes. In "The Norton dome and the nineteenth century foundations of determinism", I argue that an example of indeterminism in classical physics which has attracted attention in philosophy of physics in recent years, namely the Norton come, was already discussed during the nineteenth century. However, the significance which this type of indeterminism had back then is very different from the significance which the Norton dome currently has in philosophy of physics. This is explained by the fact that determinism was conceived of in an essentially different way: in particular, the nineteenth century authors who wrote about this type of indeterminism regarded determinism as an a priori principle rather than as a property of the equations of physics. In "Vital instability: life and free will in physics and physiology, 1860-1880", I show how Maxwell, Cournot, Stewart and Boussinesq used the possibility of unstable or indeterministic mechanical systems to argue that the will or a vital principle can intervene in organic processes without violating the laws of physics, so that a strictly dualist account of life and the mind is possible. Moreover, I show that their ideas can be understood as a reaction to the law of conservation of energy and to the way it was used in physiology to exclude vital and mental causes. In "The nineteenth century conflict between mechanism and irreversibility", I show that in the late nineteenth century, there was a widespread conflict between the aim of reducing physical processes to mechanics and the recognition that certain processes are irreversible. Whereas the so-called reversibility objection is known as an objection that was made to the kinetic theory of gases, it in fact appeared in a wide range of arguments, and was susceptible to very different interpretations. It was only when the project of reducing all of physics to mechanics lost favor, in the late nineteenth century, that the reversibility objection came to be used as an argument against mechanism and against the kinetic theory of gases. In "Continuity in nature and in mathematics: Boltzmann and Poincaré", I show that the development of rigorous foundations of differential calculus in the nineteenth century led to concerns about its applicability in physics: through this development, differential calculus was made independent of empirical and intuitive notions of continuity and was instead based on mathematical continuity conditions, and for Boltzmann and Poincaré, the applicability of differential calculus in physics depended on whether these continuity conditions could be given a foundation in intuition or experience. In the final paper, "Determinism around 1900", I briefly discuss the implications of the developments described in the previous two papers for the history of determinism in physics, through a discussion of determinism in Mach, Poincaré and Boltzmann. I show that neither of them regards determinism as a property of the laws of mechanics; rather, for them, determinism is a precondition for science, which can be verified to the extent that science is successful.

Montesquieu's Considérations sur les causes de la grandeur des Romains et de leur décadence (1733/1734) is a methodological exercise in causal explanation on the meso-level applied to the subject of the military rise and fall of Rome. Rome is described as a system with contingent initial conditions that have a strong path-determining effect. Contingent and plastic initial configurations become highly determining in their subsequent operation, thanks to self-reinforcing feedback loops. Montesquieu's method seems influenced by the ruthless commitment to efficient (...) causality and the reductionism of seventeenth-century mechanicist philosophy; but in contrast to these predecessors, he is more interested in dynamic processes than in unchangeable substances, and his use of efficient causality in the context of a system approach implies a form of holism that is lacking in his predecessors. The formal and conceptual analysis in this article is in many ways complementary with Paul Rahe's recent predominantly political analysis of the Considérations. At the same time, this article points to a problem in the works on the Enlightenment by Jonathan Israel: his account stresses a one-dimensional continuum consisting of Radical, Moderate and Counter-Enlightenment. This invites Israel to place the combined religious, political and philosophical views of each thinker on one of these three points. His scheme runs into trouble when a thinker with moderate religious and political views produces radical philosophical concepts. Montesquieu's Considérations is a case in point. (shrink)

I develop a new argument to the effect that past causal chains cannot extend back infinitely, but must instead terminate in a first uncaused cause. It has the advantage of sidestepping a historically prominent objection to cosmological arguments of this general type, one leveled by Aquinas and various other Scholastics.

This book, first published in 1936, divides into roughly two parts: a re-examination of historical material; and a positive theory of causation suggested by the results of this re-examination. The historical study discloses an ambiguity in the meanings of causation and determinism; it discloses also that this ambiguity is transferred to the meaning of freedom.
