Recently, philosophers of biology have debated the status of the evolutionary process: is it deterministic or indeterministic? I argue that there is insufficient reason to favor one side of the debate over the other, and that a more philosophically defensible position argues neither for the determinacy nor for the indeterminacy of the evolutionary process. In other words, I maintain that the appropriate stand to take towards the question of the determinism of the evolutionary process is agnosticism. I then suggest (...) that an examination of the phenomenon of developmental noise might yield a solution to the problem. (shrink)

It is certainly true that we could give an account in mechanistic terms of what there is which would be, in one sense, as complete account of what there is. If everything listed in the account were put in a pile, for example, there might be nothing left out of the pile for someone to go and fetch to it. This would be one sense in which we could give, in mechanistic or purely physical terms, a complete account of what (...) there is. But there is a more important sense in which an account in mechanistic terms cannot be allowed to be complete, because it could not include language qua language or any particular occasion of the use of language qua language, such as the giving of that account itself. I want to go on to argue now that this claim means that we cannot drop the concept of person, and that any Determinist or Physicalist who tries to make such a move is in a self-stultifying position. If we are to have any concepts at all we must have the concept of purposive action and thus the concepts of agent and person. (shrink)

The aim of this paper is to argue that very often one is not able to distinguish between deterministic processes governed by some dynamical systems and stochastic processes.

The central question of this paper is: are deterministic and indeterministic descriptions observationally equivalent in the sense that they give the same predictions? I tackle this question for measure-theoretic deterministic systems and stochastic processes, both of which are ubiquitous in science. I first show that for many measure-theoretic deterministic systems there is a stochastic process which is observationally equivalent to the deterministic system. Conversely, I show that for all stochastic processes there is a measure-theoretic (...) deterministic system which is observationally equivalent to the stochastic process. Still, one might guess that the measure-theoretic deterministic systems which are observationally equivalent to stochastic processes used in science do not include any deterministic systems used in science. I argue that this is not so because deterministic systems used in science even give rise to Bernoulli processes. Despite this, one might guess that measure-theoretic deterministic systems used in science cannot give the same predictions at every observation level as stochastic processes used in science. By proving results in ergodic theory, I show that also this guess is misguided: there are several deterministic systems used in science which give the same predictions at every observation level as Markov processes. All these results show that measure-theoretic deterministic systems and stochastic processes are observationally equivalent more often than one might perhaps expect. Furthermore, I criticise the claims of the previous philosophy papers Suppes (1993, 1999), Suppes and de Barros (1996) and Winnie (1998) on observational equivalence. (shrink)

The guiding question of this paper is: how similar are deterministic descriptions and indeterministic descriptions from a predictive viewpoint? The deterministic and indeterministic descriptions of concern in this paper are measure-theoretic deterministic systems and stochastic processes, respectively. I will explain intuitively some mathematical results which show that measure-theoretic deterministic systems and stochastic processes give more often the same predictions than one might perhaps have expected, and hence that from a predictive viewpoint these descriptions are (...) quite similar.

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.

Determinism and chance seem to be irreconcilable opposites: either something is chancy or it is deterministic but not both. Yet there are processes which appear to square the circle by being chancy and deterministic at once, and the appearance is backed by well-confirmed scientific theories such as statistical mechanics which also seem to provide us with chances for deterministic processes. Is this possible, and if so how? In this essay I discuss this question for probabilities (...) as they occur in the empirical sciences, setting aside metaphysical questions in connection with free will, divine intervention and determinism in history.

A modal logic for translating a sequence of English sentences to a sequence of logical forms is presented, characterized by Kripke models with points formed from input/output sequences, and valuations determined by entailment relations. Previous approaches based (to one degree or another) on Quantified Dynamic Logic are embeddable within it. Applications to presupposition and ambiguity are described, and decision procedures and axiomatizations supplied.

There are results which show that measure-theoretic deterministic models and stochastic models are observationally equivalent. Thus there is a choice between a deterministic and an indeterministic model and the question arises: Which model is preferable relative to evidence? If the evidence equally supports both models, there is underdetermination. This paper first distinguishes between different kinds of choice and clarifies the possible resulting types of underdetermination. Then a new answer is presented: the focus is on the choice between a (...) Newtonian deterministic model supported by indirect evidence from other Newtonian models which invoke similar additional assumptions about the physical systems and a stochastic model that is not supported by indirect evidence. It is argued that the deterministic model is preferable. The argument against underdetermination is then generalised to a broader class of cases. Finally, the paper criticises the extant philosophical answers in relation to the preferable model. Winnie’s (1998) argument for the deterministic model is shown to deliver the correct conclusion relative to observations which are possible in principle and where there are no limits, in principle, on observational accuracy (the type of choice Winnie was concerned with). However, in practice the argument fails. A further point made is that Hoefer’s (2008) argument for the deterministic model is untenable. (shrink)

Determinism is established in quantum mechanics by tracing the probabilities in the Born rules back to the absolute (overall) phase constants of the wave functions and recognizing these phase constants as pseudorandom numbers. The reduction process (collapse) is independent of measurement. It occurs when two wavepackets overlap in ordinary space and satisfy a certain criterion, which depends on the phase constants of both wavepackets. Reduction means contraction of the wavepackets to the place of overlap. The measurement apparatus fans out the (...) incoming wavepacket into spatially separated eigenpackets of the chosen observable. When one of these eigenpackets together with a wavepacket located in the apparatus satisfy the criterion, the reduction associates the place of contraction with an eigenvalue of the observable. The theory is nonlocal and contextual. Keywords:. (shrink)

Recent articles by Michael Heller, Carl Helrich, Peter Hodgson, Jeffrey Koperski, and Nicholas Saunders present a challenge to much current thinking on God, divine action, and cosmology. In the process, they also reveal underlying assumptions and current problems, especially in the debate over physics and divine action. In particular, three issues come up that need to be addressed further. First, what is the status of determinism, and what can physics contribute? Second, what kind of divine action are we talking about? (...) Third, what is the relationship between God and time, and how does this affect claims about the personhood of God? While these essays present necessary critiques and interesting, positive proposals, they also reveal unresolved tensions that need to be addressed. (shrink)

This paper engages with one debate in the emerging field of neuroethics. It is sometimes claimed on the strength of neuroscientific research that our actions are causally determined and therefore not truly free, or more modestly that brain structures or processes constrain some choices and actions, raising questions about our moral responsibility for them. I argue that a Reformed account of providence, sin and grace offers an account of causation able to resist hard determinism, reframes concepts of freedom and (...) responsibility, and provides a theological perspective for evaluating medical interventions in brain activity. Thus the paper not only contributes to a neuroethical debate, but also illustrates the capacity of Reformed ethics to respond creatively to novel problems. (shrink)

At the heart of the Stoic theory of modality is a strict commitment to bivalence, even for future contingents. A commitment to both future truth and contingency has often been thought paradoxical. This paper argues that the Stoic retreat from necessity is successful. it maintains that the Stoics recognized three distinct senses of necessity and possibility: logical, metaphysical and providential. Logical necessity consists of truths that are knowable a priori. Metaphysical necessity consists of truths that are knowable a posteriori, a (...) world order according to certain metaphysical principles and natures that god crafts within the constraints of matter. Finally, what is providentially necessary is what occurs according to the chain of fate, but only once it is in process or past. -/- The method of the paper is a close reading of Diogenes Laertius 7.75, adducing broad textual evidence along the way, to show that the Stoic theory of modality embraces Philonian possibility, both that which is capable of being true as a matter of logical consistency, and that which is possible according to the bare fitness of the entity. What differentiates the Stoics from Philo is their additional commitment to possibility as opportunity, resisting the collapse of determinism into necessity. (shrink)

We describe a recent approach for distinguishing between stochastic and deterministic sources of variability, focusing on the mammalian cell cycle. Variability between cells is often attributed to stochastic noise, although it may be generated by deterministic components. Interestingly, lineage information can be used to distinguish between variability and determinism. Analysis of correlations within a lineage of the mammalian cell cycle duration revealed its deterministic nature. Here, we discuss the sources of such variability and the possibility that the (...) underlying deterministic process is due to the circadian clock. Finally, we discuss the “kicked cell cycle” model and its implication on the study of the cell cycle in healthy and cancerous tissues. (shrink)

Most of the free will debate operates under the assumption that classic determinism and indeterminism are the only metaphysical options available. Through an analysis of Dennett’s view of free will as gradually evolving this article attempts to point to emergentist, interactivist and temporal metaphysical options, which have been left largely unexplored by contemporary theorists. Whereas, Dennett himself holds that “the kind of free will worth wanting” is compatible with classic determinism, I propose that his models of determinism fit poorly with (...) his evolutionary theory and naturalist commitments. In particular, his so-called “intuition pumps” seem to rely on the assumption that reality will have a compositional bottom layer where appearance and reality coincide. I argue that instead of positing this and other “unexplained explainers” we should allow for the heretical possibility that there might not be any absolute bottom, smallest substances or universal laws, but relational interactions all the way down. Through the details of Dennett’s own account of the importance of horizontal transmission in evolution and the causal efficacy of epistemically limited but complex layered “selves,” it is argued that our autonomy is linked to the ability to affect reality by controlling appearances.

Reductionism--understanding complex processes by breaking them into simpler elements--dominates scientific thinking around the world and has certainly proved a powerful tool, leading to major discoveries in every field of science. But reductionism can be taken too far, especially in the life sciences, where sociobiological thinking has bordered on biological determinism. Thus popular science writers such as Richard Dawkins, author of the highly influential The Selfish Gene, can write that human beings are just "robot vehicles blindly programmed to preserve the (...) selfish molecules known as genes." Indeed, for many in science, genes have become the fundamental unit for understanding human existence: genes determine every aspect of our lives, from personal success to existential despair: genes for health and illness, genes for criminality, violence, and sexual orientation. Others would say that this is reductionism with a vengeance. In Lifelines, biologist Steven Rose offers a powerful alternative to the ultradarwinist claims of Dawkins, E.O. Wilson, Daniel Dennett and others. Rose argues against an extreme reductionist approach that would make the gene the key to understanding human nature, in favor of a more complex and richer vision of life. He urges instead that we focus on the organism and in particular on the organism's lifeline: the trajectory it takes through time and space. Our personal lifeline, Rose points out, is unique--even identical twins, with identical genes at birth, will differ over time. These differences are obviously not embedded in our genes, but come about through our developmental trajectory in which genes, as part of the biochemical orchestra of trillions of cells in each human body, have an important part--but only a part--to play. To illustrate this idea, Rose examines recent research in modern biology, and especially two disciplines--genetics (which looks at the impact of genes on form) and developmental biology (which examines the interaction between the organism and the environment)--and he explores new ideas on biological complexity proposed by scientists such as Stuart Kauffman. He shows how our lifelines are constructed through the interplay of physical forces--such as the intrinsic chemistry of lipids and proteins, and the self-organizing and stabilizing properties of complex metabolic webs--and he reaches a startling conclusion: that organisms are active players in their own fate, not simply the playthings of the gods, nature, or the inevitable workings out of gene-driven natural selection. The organism is both the weaver and the pattern it weaves. Lifelines will be a rallying point for all who seek an alternative to the currently fashionable, deeply determinist accounts which dominate popular science writing and, in fact, crowd the pages of some of the major scientific journals. Based on solid, state-of-the-art research, it not only makes important contributions to our understanding of Darwin and natural selection, but will swing the pendulum back to a richer, more complex view of human nature and of life.

Drift is often characterized in statistical terms. Yet such a purely statistical characterization is ambiguous for it can accept multiple physical interpretations. Because of this ambiguity it is important to distinguish what sorts of processes can lead to this statistical phenomenon. After presenting a physical interpretation of drift originating from the most popular interpretation of fitness, namely the propensity interpretation, I propose a different one starting from an analysis of the concept of drift made by Godfrey-Smith. Further on, I (...) show how my interpretation relates to previous attempts to make sense of the notion of expected value in deterministic setups. The upshot of my analysis is a physical conception of drift that is compatible with both a deterministic and indeterministic world. (shrink)

Benjamin Libet's influential publications have raised important questions about voluntarist accounts of action. His findings are taken as evidence that the processes in the central nervous system associated with the initiation of an action occur earlier than the decision to act. However, in light of the methods employed and of relevant findings drawn from research addressed to the timing of neurobehavioural processes, Libet's conclusions are untenable.

Philosophers have since long been relying on their own intuitions to shore up their own belief about agency and about the possibility of reconciliation with the domain of physical events that seems to be freewheeled by an underlying necessitarian process. In a certain philosophical circle, a trend has now emerged to put unprimed intuitions to test through psychological experiments, in order to figure out whether philosophers should exercise some temperance in bringing their own belief about agency to the fore, and (...) the possible sources of the intuitional dilemma. This paper aims to explore the folk concept of agency and figure out the implications of the extant empirical work for our concept of free will. (shrink)

Penrose [40] has discussed a new point of view concerning the nature of physics that might underline conscious thought processes. He has argued that it might be the case that some physical laws are not computable, i.e. they cannot be properly simulated by computer; such laws can most probably arise on the “no-man’s-land” between classical and quantum physics. Furthermore, conscious thinking is a non-algorithmic activity. He is opposing both strong AI , and Searle’s [47] contrary viewpoint mathematical “laws”).

In this article we study the question of free will from an interdisciplinary angle, drawing on philosophy, neurobiology and physics. We start by reviewing relevant neurobiological findings on the functioning of the brain, notably as presented in (Koch 2009); we assess these against the physics of (in)determinism. These biophysics findings seem to indicate that neuronal processes are not quantum but classical in nature. We conclude from this that there is little support for the existence of an immaterial ‘mind’, capable (...) of ruling over matter independently of the causal past. But what, then, can free will be ? We propose a compatibilist account that resonates well with neurobiology and physics, and that highlights that free will comes in degrees – degrees which vary with the conscious grasp the ‘free’ agent has over his actions. Finally, we analyze the well-known Libet experiment on free will through the lens of our model. We submit this interdisciplinary investigation as a typical case of naturalized philosophy: in our theorizing we privilege assumptions that find evidence in science, but our conceptual work also suggests new avenues for research in a few scientific disciplines.

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)

In this article I shall aim at showing that there exists beneath the surface of many why-questions about human behaviour a nest of deterministic assumptions which can preclude their ever being truly answered. A symptom of the presence of these underlying assumptions can be observed in an explanation-seeking dialogue in which the questioner persistently tries to discover ‘why’ a certain human behaviour occurred. He repeats his why-question until he gets the type of answer he wants, but in the process (...) he effectively reasons in a circle. If the repeated questioning with its implied circular reasoning becomes chronic, then the questioner will beg the question with regards to the answer he desires and consequently run the risk of missing the truth.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 12.1 (2005) 83-85 [Access article in PDF] Lacan, Science, and Determinism Douglas McConnell Grant Gillett Keywords Lacan, the unconscious, free will Van Staden And Hinshelwood's commen-taries raise a number of issues, but there are two particular themes common to both that we pick up in this response.The first theme concerns the reconcilability of Lacanian theory to the disciplines of analytic philosophy and "Anglo-American positivist psychiatry." (...) This is closely related to the relationship between the unconscious and the empirical sciences discussed in the editorial (McConnell and Pickering 2005). The second theme concerns the relevance of Lacanian theory to our understanding of free will and the structure of the mind. Lacan, Analytic Philosophy, and Scientific Psychiatry First, psychoanalysis or psychotherapy generally should not try to reunite with neuroscience because of the fundamental difference in their approaches to the patient, which is likely to mean that even if a theoretical rapprochement can be found, a working relationship is unlikely.Although there are many facets of Lacan's theory that were not addressed in our paper and even if many of those are totally irreconcilable to analytic philosophy, we believe that we have addressed the most ontologically fundamental issues and that these can genuinely contribute to and challenge analytic philosophy of mind.As Hinshelwood points out, psychiatry does operate with a philosophical basis, critical (or sometimes relatively uncritical) scientific realism (even though it may not be acknowledged), and it as such it can legitimately be contributed to or challenged by the philosophical aspects of Lacanian theory outlined in our paper.In fact, the theoretical basis is evinced in van Staden's commentary when he remarks on the relation between Lacanian theory and psychiatry: "... the unconscious is not only structured like a language but actually reflects and is produced by linguistic interaction between the subject and others. This is a difficult claim to verify, no doubt, but it prompts further related questions... whether the conscious mind is structured like a language" (van Staden 2005, 78). And one must ask whether this is the kind of claim that can be verified or whether it is a hermeneutic claim (in somewhat the way suggested by Jaspers), serving more as a framing belief to allow people to make sense of what has influenced them in their life histories and is currently played out in their relationships with others. We would lean toward this interpretation of the unconscious, explicitly distancing ourselves from any overreaching, quasi-scientific realism about unconscious contents and mental structures, but clinging to the thought that dealing with such contents is an essential part of the therapeutic encounter. [End Page 83]Looked at in this way, both the Lacanian unconscious and conscious mental life bear the imprint of language due to the subject's immersion and participation in the symbolic realm. This may seem a "difficult claim to verify," but because verification is linked to the scientific framework of inquiry rather than the hybrid that is clinical knowledge, we would better regard it as being difficult to establish as an axiom of therapy. The linguistic structure of the conscious and unconscious mind is, on this account, a conceptual implication of the role of the symbolic register in thought and not a thesis that requires verification (a Wittgensteinian thesis espoused by a number of contemporary philosophers, including Dummett and Davidson).As it happens, cognitive science has found linguistic structure to be important in operations of the cognitive unconscious (arguably different from the dynamic unconscious due to the former's dependence on scientific experiment and the latter's connections to life history rather than mere psychological or cognitive traits [see Gillett and McConnell 2005]). Given that language and problem solving are so closely intertwined, it would suggest that cognitive science was overlooking something important rather than damaging Lacanian theory if linguistic structure did not appear on cognitive science's "radar." So, how does language logically (in the sense defended by Husserl and Frege, that is, to do with the sense or content of thoughts not merely the processes underpinning one's contingently evolving stream...

The definition of “model of a system” in terms of a homomorphism of the states of the system is evaluated and an alternative definition in terms of sequence generators is proposed. Sequence generators are finite graphs whose points represent complete states of a system. Sequence generators include finite automata and other information processing systems as special cases. It is shown how to define models in terms of a projection operator which applies to any sequence generator which has an output projection (...) and yields a new sequence generator. A model produced by the projection operator is embedded in the system it models. The notion of embedding is discussed informally and some questions raised about the relations of deterministic, indeterministic, and probabilistic models and systems. (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.

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.

A line of research within embodied cognition seeks to show that an organism’s body is a determinant of its conceptual capacities. Comparison of this claim of body determinism to linguistic determinism bears interesting results. Just as Slobin’s (1996) idea of thinking for speaking challenges the main thesis of linguistic determinism, so too the possibility of thinking for acting raises difficulties for the proponent of body determinism. However, recent studies suggest that the body may, after all, have a determining role in (...) cognitive processes of sentence comprehension. (shrink)

In this work we try to study theories of causation based upon causal processes and causal interactions in the context of classical and quantum physics. Our central aim is to find out whether such causal theories are compatible with the world picture suggested by contemporary theories of physics. In the first part, we review, compare and try to place among more general taxonomical schemes, the causal theories by Russell (the causal lines approach), Reichenbach (mark method, probabilistic causality and the (...) principle of common cause), Salmon (mark method, structure, invariant and conserved quantities approaches) and Dowe (conserved quantity theory). In the second part of the work, we deal with some problems that process theories of causation face whenever one tries to define, rigorously, causal concepts (e.g. “causal process” or “conjunctive common cause”) in the context of classical relativistic physical theories (van Dam – Wigner particle theory, the free Klein-Gordon field, classical electromagnetic theory) as well as quantum theories (algebraic relativistic quantum field theory). In this vein, special attention has been given to the locality problem in physical theories as it emerges from the structure of local classical the quantum theories (semantic locality), the relation between global and local conditions for physical systems (global and local determinism) as well as the problem of action at a distance, which is of central importance for the theories of causation under examination (Bell’s inequalities, EPR paradox, Reeh-Schlieder theorem and local independence conditions). We argue for three different theses: first, there are physical theories in the context of which it is impossible even to formulate the necessary physical hypotheses that allow us to define basic causal concepts and causal principles; second, there are physical theories which allow us to formulate these hypotheses only ad hoc; finally, in some cases it is necessary to revise basic causal principles and concepts bequeathed by the philosophical tradition.

In this paper, I intend to present the way in which contingency and causal determinism relate in some major late-medieval views on the metaphysics of causation. I will focus on Thomas Aquinas, John Duns Scotus, William of Ockham, and John Buridan. First, I will show that Scotus’s new insights into the metaphysics of modalities had important consequences for the way contingency was related to causality: Ockham and Buridan do not consider contingency as a by-product of the necessary emanation of God (...) any more but as a distinctive property of God as the first cause and, therefore, of the created world as a whole. Second, I will show that the growing interest from Scotus onward in explaining and justifying inductive reasoning led to an extensive analysis of the nature and function of the principle of the uniformity of nature. Third, I will explain why the progressive psychologization of final causes led to the exclusion of final explanations from physics. The consequence of this process is the development a new way of conceiving chance and hazard, and the separation between free and natural agents. We can speak here of a tendentially mechanistic picture of the world. (shrink)

In this paper we first briefly review Bell's (1964, 1966) Theorem to see how it invalidates any deterministic "hidden variable" account of the apparent indeterminacy of quantum mechanics (QM). Then we show that quantum uncertainty, at the level of DNA mutations, can "percolate" up to have major populational effects. Interesting as this point may be it does not show any autonomous indeterminism of the evolutionary process. In the next two sections we investigate drift and natural selection as the locus (...) of autonomous biological indeterminacy. Here we conclude that the population-level indeterminacy of natural selection and drift are ultimately based on the assumption of a fundamental indeterminacy at the level of the lives and deaths of individual organisms. The following section examines this assumption and defends it from the determinists' attack. Then we show that, even if one rejects the assumption, there is still an important reason why one might think evolutionary theory (ET) is autonomously indeterministic. In the concluding section we contrast the arguments we have mounted against a deterministic hidden variable account of ET with the proof of the impossibility of such an account of QM. (shrink)

Neuroplasticity, the capacity of the brain to induce changes in response to environmental stimuli, entails a continuous rearrangement of the neural network through a complex interaction between genetics and environment. Within this process, the plastic brain uses its internal representations to predict future conditions and proactively proceed to actions. It can be said that plasticity demands a rethinking of the concept of determinism as the process of coming-to-be is directly related to modifications produced by experience. Pure determinism and complete randomness (...) are the two ends of a spectrum of positions relevant to the debate of the existence of free will. However, none conceptually supports free decision-making. How brain activity and the conscious experience of volition are related to one another has been a matter of significant research, with a plethora of findings indicating that early brain signals precede the self-reported time of the decision to act. The meaning of these findings, however, has been debated at both a theoretical and empirical level and the controversy is still ongoing. Consciousness is intertwined with free will along the dimension of time as it would otherwise be purposeless, taking place right at the next moment. Electrical activity of the brain is a measure of neurophysiological function and contributes to the understanding of processes that underlie high-order cognitive functions. A multidisciplinary approach in the study of free will could be designed in a way that philosophical concepts are connected to neural correlates by psychologically functionalizing them in terms of cognitive abilities. Such abilities are at the margins of conscious and nonconscious sensory information and are closely linked to brain processes of executive functions like attentional control and working memory.

Notoriously, the Einstein equations of general relativity have solutions in which closed timelike curves occur. On these curves time loops back onto itself, which has exotic consequences: for example, traveling back into one's own past becomes possible. However, in order to make time travel stories consistent constraints have to be satisfied, which prevents seemingly ordinary and plausible processes from occurring. This, and several other "unphysical" features, have motivated many authors to exclude solutions with CTCs from consideration, e.g. by conjecturing (...) a chronology protection law. In this contribution we shall investigate the nature of one particular class of exotic consequences of CTCs, namely those involving unexpected cases of indeterminism or determinism. Indeterminism arises even against the backdrop of the usual deterministic physical theories when CTCs do not cross spacelike hypersurfaces outside of a limited CTC-region|such hypersurfaces fail to be Cauchy surfaces. We shall compare this CTC-indeterminism with four other types of indeterminism that have been discussed in the philosophy of physics literature: quantum indeterminism, the indeterminism of the hole argument, non-uniqueness of solutions of differential equations and lack of predictability due to insuffcient data. By contrast, a certain kind of determinism appears to arise when an indeterministic theory is applied on a CTC: things cannot be different from what they already were. Again we shall make comparisons, this time with other cases of determination in physics. We shall argue that on further consideration both this indeterminism and determinism on CTCs turn out to possess analogues in other, familiar areas of physics. CTC- indeterminism is close to the epistemological indeterminism we know from statistical physics, while the "fixedness" typical of CTC-determinism is pervasive in physics. CTC- determinism and CTC-indeterminism therefore do not provide incontrovertible grounds for rejecting CTCs as conceptually inadmissible. (shrink)

The general moral decline widely perceived to be in process in both the UK and the USA is no doubt the effect of many causes. The present paper attends to only one, the de-moralization more or less unintentionally encouraged by the working of the machinery of the welfare state, and then further encouraged by a deliberate and systematic de-moralization of that machinery. It attempts to undermine a main assumption supporting that de-moralization, and thus contribute to the campaign for re-moralization waged (...) in recent years by, among others, the Social Affairs Unit in London and like-minded think-tanks in the USA.

This article presents a relational criticism of the "morphogenetic theory" of M. Archer. This theory is founded and representative of the most influential mode of perception of the social universe of the last few decades: co-determinism (structure ↔ agency). Co-determinism's influence can be explained by its integration of modern general presuppositions like freedom, individualism, and the quest for a new social order. By identifying five basic principles of relational sociology, we see that Archer's co-deterministic theory offers a complicated solution (...) to avoid voluntarism and co-determinism, limits the potential of sociological imagination, cannot adequately see the fluidity of social processes, produces a certain reification of social structures and agency, and is based on an inconsistent use of egocentric and relational perspectives. These problems can be avoided if we use a relational approach (actor ↔ actor ⇒ structures) based on the study of complex and empirical trans-actions. (shrink)

This article introduces comparative process tracing as a two-step methodological approach that combines theory, chronology, and comparison. For each studied case, the processes leading “from A to B” are reconstructed and analyzed in terms of ideal-type social mechanisms and then compared by making use of the identified mechanisms and ideal-type periodization. Central elements of CPT are path dependence, critical junctures and focal points, social mechanisms, context, periodization, and counterfactual analysis. The CPT approach is described, discussed, and compared with more (...) formal and deterministic forms of process tracing, which are found to be less fruitful for systematic comparison. (shrink)

We introduce a general framework for solving the problem of a computer collecting and combining information from various sources. Unlike previous approaches to this problem, in our framework the sources are allowed to provide information about complex formulae too. This is enabled by the use of a new tool — non-deterministic logical matrices. We also consider several alternative plausible assumptions concerning the framework. These assumptions lead to various logics. We provide strongly sound and complete proof systems for all the (...) basic logics induced in this way. (shrink)

Socially Assistive Robots are increasingly conceived as applicable tools to be used in aged care. However, the use carries many negative and positive connotations. Negative connotations come forth out of romanticized views of care practices, disregarding their already established technological nature. Positive connotations are formulated out of techno-deterministic views on SAR use, presenting it as an inevitable and necessary next step in technological development to guarantee aged care. Ethical guidance of SAR use inspired by negative connotations tends to be (...) over-restrictive whereas positive connotations tend to provide over-permissive guidance. To avoid these extremes, we report on the development and content of 21 ethical orientations regarding SAR use in aged care. These orientations resulted from a multi-phased project, which consisted of empirical-ethical research focusing on older adults’ intuitions regarding SAR use and philosophical-ethical research focusing on philosophical-ethical argumentations regarding SAR use. This project led to the Socio-historical contextualization of the ethics of SAR use, in which the ethical impact of SAR use is localized on three interrelated analysis levels: societal, organizational, and individual-relational. The 21 novel orientations regarding SAR use are structured according to these levels and further categorized into foundational and applied orientations. The first category leads to critical reflection on SAR use while the latter category inspires decision-making processes regarding this use. While going beyond the care-romantic and techno-deterministic gaze of SAR use in aged care, the described orientations balance themselves between their over-restrictiveness and over-permissiveness.

The Yoga Sūtra (YS) is perhaps the most popular book of Indian philosophy today the world over. It is widely regarded by practitioners of Yoga as a conceptual manual for yoga and there are several competing translations of the work on the market. Yet, the Yoga Sūtra is also widely regarded as a difficult text to read. It is written in a dense, aphoristic, sūtra format. In the introductory section, I tackle the question of methodology in reading the Yoga Sūtra. (...) In the second explication section, I move to the crux: Yoga and Sāṅkhya—two schools that are often conflated with each other—present two very differing accounts of Freedom and Determinism. In the third section, I review the considerations that Yoga presents for its Normative Compatibilism. Yoga is depicted by the Yoga Sūtra as a process that we explore and finalize in public space. The goal of extricating ourselves from nature so as to deliver us into a personal world is the aim that underlies the project of liberating ourselves from external coercion in public. Ethics, or Dharma, is the normative light that makes us unique and makes us individual persons, as opposed to functions of nature or our environment. Isolation, autonomy, kaivalya, is our freedom as individuals in a social world free from external influence and coercion. (shrink)
