In this paper, I defend an empiricist account of modality that keeps a substantive account of modal commitment, but throws out the metaphysics. I suggest that if we pair a deflationary attitude toward representation with a substantive account of how scientific models are constructed and put to use, the result is an account that deflates the metaphysics of modal commitment without deflating the content of modal claims.

In this paper, I examine three mutually inconsistent claims that are commonly attributed to Hume: all beliefs are involuntary; some beliefs are subject to normative appraisal; and that ‘Ought implies Can’. I examine the textual support for such ascription, and the options for dealing with the puzzle posed by their inconsistency. In what follows I will put forward some evidence that Hume maintains each of the three positions outlined above. I then examine what I call the ‘prior voluntary action’ solution. (...) I argue that this position in any form fails to account for synchronic rationality. I then raise more specific objections depending on how we disambiguate the position, which can be read as either granting beliefs derivative voluntariness, or as denying their normative significance; the former version is inconsistent with Hume’s treatment of natural abilities, while the latter falls to a regress given Hume’s thesis regarding the inability of actions and passions to be subject to epistemic normativity. I then propose to reject instead for two reasons: first, the weakness of textual support for such an ascription; secondly, Hume’s explicit recognition of the irrelevance of involuntariness to normative evaluation in the moral case.

Carnap was one of the first to use the term 'non-cognitivism'. His linguistic pluralism and voluntarism, and his deflationary views of ontology and semantics, are highly congenial to those of us who want to take non-cognitivism in the direction of global expressivism. In his own case, however, this move is in tension with his continued endorsement of what he calls 'the general thesis of logical empiricism', that 'there is no third kind of knowledge besides empirical and logical knowledge.’ So while (...) Carnap clears a path towards global expressivism, he doesn't seem to appreciate what it requires him to leave behind. (shrink)

I present an exemplary Humean modal epistemology. My version takes inspiration from but incurs no commitment to both Hume’s historical position and Lewis’s Humeanism. Modal epistemology should meet two challenges: the Integration challenge of integrating metaphysics and epistemology and the Reliability challenge of giving an account of how our epistemic capacities can be reliable in detecting modal truth. According to Lewis, modal reasoning starts from certain Humean principles: there is only the vast mosaic of spatiotemporally distributed local matters of fact. (...) The facts can be arbitarily recombined. These principles cannot be taken for granted. I suggest a bottom-up approach instead: Humean principles of recombining the mosaic of facts can be retrieved from the evolutionarily instilled and empirically informed use of imagination in exploring everyday circumstantial possibilities. This use of imagination conforms to a primitive conception of matter as freely recombinable. The modal beliefs that can be obtained from generalizing the more elementary exercise of imagination have to be corrected. Recombination is limited by sortal criteria of identity. Moreover, the overall picture of a recombinable spatiotemporal mosaic must be weighed against the results of science. (shrink)

David Hume and other philosophers doubt that causality can be perceived directly. Instead, observers become aware of it through inference based on the perception of the two events constituting cause and effect of the causal relation. However, Hume and the other philosophers primarily consider causal relations in which one object triggers a motion or change in another. In this paper, I will argue against Hume’s assumption by distinguishing a kind of causal relations in which an agent is controlling the motion (...) or change of an object. I will call this kind of causal relations ‘causation-as-control’. In instances of causation-as-control, the observer does not become aware of the causality through inference based on the perception of two events (cause and effect). Rather, she perceives the two events directly and without further inference as cause and effect of a causal relation, and, therefore, the causality at work. (shrink)

In this paper, I examine Hume’s account of an important class of causal belief which he calls “general rules”. I argue that he understands general rules, like all causal beliefs, as lively ideas which are habitually associated with our impressions or memories. However, I argue, he believes that they are unlike any reflectively produced causal beliefs in that they are produced quickly and automatically, such that they occur independently of any other processes of reasoning. Given this, I argue, Hume appears (...) to understand general rules as relatively simple beliefs, expressible only via generic sentences, like “birds lay eggs”. (shrink)

Hume regards the ‘absolute’ necessity attending demonstrable propositions as an expression of the limitations of human imagination. When we register our modal commitments in ordinary descriptive language, affirming that there are such-and-such absolute necessities, possibilities, and impossibilities, we are projecting our sense of what the human mind can and cannot conceive. In some ways the account parallels Hume’s famous treatment of the necessity of causes, and in some respects it anticipates recent expressivist theories of absolute modality. I marshal the evidence (...) for this interpretation, show how it can explain a number of otherwise puzzling features of Hume’s modal epistemology and metaphysics, and situate this account of our modal discourse in Hume’s wider programme for a science of human nature. (shrink)

Although the main focus of Hume’s career was in the humanities, his work also has an observable role in the historical development of natural sciences after his time. To show this, I shall center on the relation between Hume and two major figures in the history of the natural sciences: Charles Darwin (1809–1882) and Albert Einstein (1879–1955). Both of these scientists read Hume. They also found parts of Hume’s work useful to their sciences. Inquiring into the relations between Hume and (...) the two scientists shows that his philosophical positions had a partial but constructive role in the formation of modern biology and physics. This is accordingly a clear indication of Hume’s impact on the scientific tradition. Before proceeding to analyze Hume’s contribution to the history of science, it is important to address his broader role in the history of philosophy of science. Hume’s discussions concerning the topics of causation, induction, the distinction between mathematical and empirical propositions, and laws of nature have been important for the philosophy of science of the nineteenth and twentieth centuries.

According to the standard view of particularity, an entity is a particular just in case it necessarily has a unique spatial location at any time of its existence. That the basic entities of the world we speak about in common sense and science are particular entities in this sense is the thesis of “foundational particularism,” a theoretical intuition that has guided Western ontological research from its beginnings to the present day. The main aim of this paper is to review the (...) notion of particularity and its role in ontology. I proceed in four steps. First, I offer a brief reconstruction of the tasks of ontology as “theory of categorial inference in L”. An ontological theory states which (combinations of) entity types or categories make true L-sentences true; the features of the stipulated categories explain why L-speakers are entitled to draw certain material inferences from the classificatory expressions of L. Second, I draw attention to the fact that since Aristotle this theoretical program typically has been implemented with peculiar restrictions prescribing certain combinations of category features, e.g., the combination of particularity, concreteness, individuality, and subjecthood. I briefly sketch how these restrictions of the “substance paradigm” or “myth of substance” are reinforced by the standard readings of predicate-logical constants, viz. the existential quantifier and the identity sign. Third, I argue that in the context of the substance paradigm foundational particularism is incoherent. I discuss the current standard conceptions of particulars as developed in the debate about individuation (bare particulars, nude particulars, tropes) and show that their main difficulties derive from the traditional restriction that particulars are so also logical subjects and/or individuals. Fourth, to show that the traditional linkages of category features are not conceptual necessities, I sketch the outlines of an ontology (General Process Theory) based on non-particular individuals. For ontologists in computer science working with description logic this monocategoreal ontology based on more or less generic ‘dynamics’ may hold special interest. As General Process Theory documents, ontologists may well abandon the notion of particularity: in common sense and science we do reason about items that have a unique spatial location at any time, but the uniqueness of their location can be taken to be a contingent affair.

A characteristically Humean pattern of explanation starts by claiming that we have a certain kind of feeling in response to some objects and then takes our having such feelings to provide an explanation of how we come to think of those objects as having some feature that we would not otherwise be able to think of them as having. This core pattern of explanation is what leads Simon Blackburn to dub Hume ‘the first great projectivist.’ This paper critically examines the (...) philosophical and textual basis for interpreting Hume as a causal projectivist. I argue that projectivist interpretations of Hume's account of causation are motivated by two convictions: that beliefs about causation, according to Hume, are not just beliefs about regularity relations and that believing that two events are necessarily connected, according to Hume, is not merely having a belief about something that occurs in one's mind. I suggest that the latter conviction is worth revisiting, both for textual and philosophical reasons. (shrink)

The modalities come into the world by being projections or objectivizations of our epistemic constitution. Thus this paper is a statement of Humean projectivism. In fact, it goes beyond Simon Blackburn’s version. It is also designed as a comprehensive counter-program to David Lewis’ program of Humean supervenience. In detail, the paper explains: Already the basic fact that the world is a world of states of affairs is due to the nature of our epistemic states. Objects, which figure in states of (...) affairs and which embody metaphysical modality, are constitutable by their essential properties and in fact constituted by us according to our ontological policies. What the facts are, to which the correspondence notion of truth refers, is determined by applying an epistemic or pragmatic notion of truth to the world. Causation is a specific objectivization of our conditional beliefs. Nomicity is a ‘habit of belief’, a specific way of generalizing epistemic attitudes. This covers the basic metaphysical and natural modalities. The paper attempts to convey that talking of projection or objectivization is not just imagery, but a constructively realizable program. (shrink)

Hume’s claim that we project necessity onto objects we take to be causally related has been influential in contemporary discussions of modality, inspiring deflationary accounts of our modal commitments. Hume is commonly understood as holding that modal projection explains our judging that an effect must follow its cause. This misunderstands the role of projection in Hume’s discussions of causation and causal judgement. Projection is a diagnosis of a distinctively philosophical confusion: the commitment to mind-independent necessary connections. In arguing for this, (...) I provide an account of the psychological process that, in Hume’s view, underlies projection. This account resolves problems with Hume’s projectivism identified by his commentators. (shrink)

Hume maintained that, philosophically speaking, there is no difference between exiting a room out of the first-floor window and using the door. Nevertheless, Hume’s reason and common sense prevailed over his scepticism and he advocated that we should always use the door. However, we are currently living in a world that is more seriously committed to the Humean philosophy of empiricism than he was himself and thus the potential to act inappropriately is an ever-present potential. In this paper, I explore (...) how Hume’s two versions of causality have detrimentally affected our ability both to arrive at and to use research to improve human well-being. I illustrate my argument with an example of what I think is an incorrect yet supposedly scientifically sound assumption: that absenteeism causes poor school attainment. Instead I make the interdisciplinary argument that absenteeism is better understood as an aggravating symptom of a number of other causes of poor attainment, such as poverty and individual psychological factors. I suggest that an instrumental, punitive policy against parents whose children tend to be absent from school may be ineffectual or even counterproductive if the objective is to improve the well-being of those children. To support my argument, I introduce the critical realist idea of transfactuality. Using the example of research into moon rocks, I show how mainstream science uses transfactuality despite its empiricist aversion to it. I also suggest that it is our honesty, integrity, and stoicism that lead us to the extreme overthrow of reason and common sense that we see today in many of the UK’s social policies; an overthrow that Hume himself did not achieve. Metaphorically speaking, British professionals, stoically and honestly believing in the ability of their trusted research correlations to guide their action, are exiting out of the first-floor window rather than using the door. This is a significant barrier to our ability to devise and implement social policy. (shrink)

This contribution to a debate with Dustin McWherter evaluates his claim that Kant is a ‘non-ontologist’ or an ‘anti-ontologist’ and challenges one specific consequence which McWherter argues follows from this attribution to Kant. I argue that, while it is true that Kant restricts the domain of ‘objects’ or ‘appearances’ as he calls them to what is knowable, this does not make him an ‘anti-ontologist’.

This chapter examines the relationship between laws and mechanisms as approaches to characterising generalizations and explanations in science. I give an overview of recent historical discussions where laws failed to satisfy stringent logical criteria, opening the way for mechanisms to be investigated as a way to explain regularities in nature. This followed by a critical discussion of contemporary debates about the role of laws versus mechanisms in describing versus explaining regularities. I conclude by offering new arguments for two roles for (...) laws that mechanisms cannot subsume, one epistemically optimistic and one pessimistic, both broadly Humean. Do note that this piece is not primarily Hume exegesis; it is more of a riff in the key of Hume. (shrink)

I outline Hume’s views about conceivability evidence. Then I critically scrutinise two threats to conceivability-based modal epistemology. Both arise from Hume’s criticism of claims to knowing necessary causal relationships: Firstly, a sceptical stance towards causal necessity may carry over to necessity claims in general. Secondly, since – according to a sceptical realist reading – Hume grants the eventuality of causal powers grounded in essential features of objects, conceivability-based claims to comprehensive metaphysical possibilities seem endangered. I argue that although normal conceivability-based (...) claims are defeasible, they are prima facie vindicated. Humes Ansichten über Vorstellbarkeit als Indikator für Möglichkeit werden zusammengefasst. Dann werden zwei Schwierigkeiten für eine auf Vorstellbarkeit basierende modale Erkenntnistheorie aufgeworfen. Beide entstehen aus Humes Kritik an Ansprüchen aufWissen notwendiger kausaler Beziehungen. Erstens könnte sich eine skeptische Haltung gegenüber kausaler Notwendigkeit auf Ansprüche, notwendige Zusammenhänge zu kennen, im allgemeinen auswirken. Zweitens gesteht Hume gemäß einem skeptischen Realismus die Eventualität kausaler Kräfte zu, die in wesentlichen Eigenschaften der Dinge gründen. Dies scheint unvereinbar mit der auf Vorstellbarkeit gestützten Behauptung umfassender metaphysischer Möglichkeiten. Dagegen soll gezeigt werden, dass auf Vorstellbarkeit gestützte modale Wissensansprüche zwar widerlegbar, aber prima facie gerechtfertigt sind. (shrink)

An introduction to the Synthese topical collection "Humeanisms".

The paper claims that Hume ’s philosophy contains an ontology, i.e. an abstract exhaustive classification of what there is. It is argued that Hume believes in the existence of a mind-independent world, and that he has a classification of mind-related entities that contains four top genera: perception, faculty, principle and relation. His ontology is meant to be in conformity with his philosophy of language and epistemology, and vice versa. Therefore, crucial to Hume ’s ontology of mind-independent entities is his notion (...) of ‘supposing relative ideas ’. Entities that are referred to by means of ordinary ideas can be truly classified, whereas entities that are referred to by means of relative ideas can only be hinted at. When Hume ’s ontology is highlighted and systematised, his notion ‘the faculty of imagination’ becomes highly problematic. However, the exposition also makes it clear that Hume deserves the honorary title: the first cognitive scientist. (shrink)

What would it take for Hume to be an external world skeptic? Is Hume's position on knowledge sufficient to force him to deny that we can acquire knowledge of propositions about the external world? After all, Hume is extremely restrictive about what can be known because he requires knowledge to be immune to error. In this paper, I will argue that if Hume were a skeptic, then he must also deny a particular kind of view about what is immediately present (...) to the mind. I will argue that direct realisms—views that maintain that mind-independent things are immediately present to the mind—combine with Hume's position on knowledge to entail the negation of skepticism. So, despite his position on knowledge, Hume could still consistently reject skepticism, if he were to endorse direct realism. (shrink)

Causation is of undeniable importance to our understanding of, and interaction with our surroundings. Despite this, the correct understanding of causation remains subject to considerable philosophical controversy. In this article, I introduce the most influential philosophical theories of causation, and provide an overview of the main difficulties that has led to the currently most popular versions of these theories.

Hume is known for his claim that our idea of causation is nothing beyond constant conjunction, and that our idea of necessary connection is nothing beyond a felt determination of the mind. In short, Hume endorses a "thin" conception of causation and necessary connection. In recent years, however, a sizeable number of philosophers have come to view Hume as someone who believes in the existence of thick causal connections - that is, causal connections that allow one to infer a priori (...) the effect from the cause, and vice versa. Hume doesn't wish to deny such connections, said philosopher's claim, he only seeks to demonstrate that we can't know anything about the nature of the thick causal connections that make up the natural world. In this dissertation, I defend the old or traditional interpretation of Hume on causation. I draw attention to the important but neglected role of clear and distinct perception in Hume's thought, arguing that for Hume our impressions are clear and distinct perceptions, whereas our ideas are faint and obscure. Accordingly, Hume's copy principle - the thesis that our ideas are copies of our impressions - is Hume's way of rendering our naturally obscure and confused ideas distinct. One need only discern the impression from which said ideas are copied. In this way, I show that Hume's opinion concerning our idea of thick causation is that it's an obscure and confused idea, and that the only clear and distinct idea we can have of causation is thin causation. Furthermore, since meaning for Hume is a matter of a word's being associated with an idea, Hume thinks that an expression such as "thick causation" is meaningless or confused. In one sense, then, Hume is a positivist, and as such doesn't believe in thick causal connections. (shrink)

In his brief treatment of memory, Hume characterizes memory using two kinds of criteria: ideas’ phenomenal character and their correspondence to the past experiences from which they derived. These criteria have seemed so perplexing to interpreters, both individually and jointly, that Hume’s account of memory is commonly considered one of the weakest parts of his philosophical system. This paper defends Hume’s criteria by showing that they achieve two theoretical aims: a scientific classification of ideas and a definition of ‘memory.’ In (...) particular, I argue that Hume’s definition of ‘memory’ is cogent in light of Putnamian considerations about definitions. (shrink)

This thesis investigates Hume’s philosophy of external existence in relation to, and within the context of, his philosophy of scepticism. In his two main works on metaphysics – A Treatise of Human Nature (1739–40) and the first Enquiry (first ed. 1748) – Hume encounters a predicament pertaining to the unreflective, ‘vulgar’ attribution of external existence to mental perceptions and the ‘philosophical’ distinction between perceptions and objects. I argue that we should understand this predicament as follows: the vulgar opinion is our (...) natural and default belief for Hume, but causal reasoning reveals it to be false, and the philosophical alternative is a confabulation that we cannot permanently believe and is devoid of justification. Hume uses the fact that we cannot have a satisfactory account of belief in external existence as a sceptical consideration to motivate his wider philosophical scepticism. Hume’s response to his predicament about external existence is found in the context of his confrontation with other sceptical worries (Treatise 1.4.7 and Enquiry 12), in which Hume also reflects generally on the nature and implications of scepticism. I argue that we should characterise Hume’s position as residually sceptical. This means that, while Hume accepts the unanswerability of some sceptical problems, he denies that it is possible to eradicate all belief as a result (and denies that it is practically useful to even try) and instead uses sceptical problems as a motivation to adopt a moderately sceptical position. While we inevitably return to entertaining the vulgar belief, there is no solution to the sceptical predicament; Hume does not endorse the vulgar belief, or the philosophical system, or indeed any alternative system of the external world that might extinguish the predicament. Sceptical doubt, for Hume, does not derail intellectual pursuits, but rather modifies our attitudes in those very pursuits. (shrink)

Sir William Drummond (1770?-1828) enjoyed considerable notoriety in the early nineteenth century as the author of the Academical Questions (1805), a manifesto for immaterialism that is at the same time a creative synthesis of ancient and modern forms of scepticism. In this paper I advance an interpretation of Drummond's work that emphasises his extensive employment and adaptation of Hume's own ‘Academical or Sceptical Philosophy’. I also document the impact of the Academical Questions on the contemporary philosophical scene, including its decisive (...) influence on Shelley's philosophical development. (shrink)

The problem of justifying induction has vexed philosophers for centuries. It has been entangled with issues concerning logic and probability and the philosophy of science. This article proposes a new approach to untangling these issues and resolving the overall problem. This new approach is by way of the perspective of realist ontology. Induction should not be seen as a debased form of logic and the search for inflexible rules for justifying particular sorts of inductive inference should be abandoned. Rather, induction (...) can be justified pragmatically as a general practice because reality possesses ordered patterns. Induction, being dependent on repetition, can sometimes identify aspects of those patterns simply because the instances of repetition really do occur. Thus, confidence in conclusions based on inductive inferences is not properly to be derived from unchanging logical rules governing when and where inductive inferences may be successfully applied, but from the involvement of such inferences with a wider, deeper process in which not only deductive inferences and other inductive inferences are involved, but also a set of relations to broader bodies of relevant knowledge. That is, unlike particular deductive inferences, inductive inferences may not be engaged in isolation from all other information about the world and completely in the abstract. Induction is always connected with a process of retroduction. (shrink)

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.

Much of what Hume calls probable reasoning is deliberate and reflective. Since there are aspects to Hume’s psychology that tempt some commentators to think, on the contrary, that for Hume all such reasoning is simple and immediate, I will be concerned to emphasize Hume’s recognition of the sophisticated sort of probable reasoning (section I). Though some of the details of my case may be new, the overall point of this section should not be news to recent scholarship. But once we (...) recognize that this reflective and deliberate reasoning constitutes a significant portion of all probable reasoning, it becomes legitimate to ask how Hume accommodates this reasoning in his psychology, his ‘science of man.’ I believe that ..

The subject of this essay-based dissertation is Hume’s natural philosophy. The dissertation consists of four separate essays and an introduction. These essays do not only treat Hume’s views on the topic of natural philosophy, but his views are placed into a broader context of history of philosophy and science, physics in particular. The introductory section outlines the historical context, shows how the individual essays are connected, expounds what kind of research methodology has been used, and encapsulates the research contributions of (...) the essays. The first essay treats Newton’s experimentalist methodology in gravity research and its relation to Hume’s causal philosophy. It is argued that Hume does not see the relation of cause and effect as being founded on a priori reasoning, similar to the way in which Newton criticized non-empirical hypotheses about the causal properties of gravity. Contrary to Hume’s rules of causation, the universal law does not include a reference either to contiguity or succession, but Hume accepts it in interpreting the force and the law of gravity instrumentally. The second article considers Newtonian and non-Newtonian elements in Hume more broadly. He is sympathetic to many prominently Newtonian themes in natural philosophy, such as experimentalism, critique of hypotheses, inductive proof, and the critique of Leibnizian principles of sufficient reason and intelligibility. However, Hume is not a Newtonian philosopher in many respects: his conceptions regarding space and time, the vacuum, the specifics of causation, the status of mechanism, and the reality of forces differ markedly from Newton’s related conceptions. The third article focuses on Hume’s Fork and the proper epistemic status of propositions of mixed mathematics. It is shown that the epistemic status of propositions of mixed mathematics, such as those concerning laws of nature, is that of matters of fact. The reason for this is that the propositions of mixed mathematics are dependent on the Uniformity Principle. The fourth article analyzes Einstein’s acknowledgement of Hume regarding special relativity. The views of the scientist and the philosopher are juxtaposed, and it is argued that there are two common points to be found in their writings, namely an empiricist theory of ideas and concepts and a relationist ontology regarding space and time.

Berkeley’s critique of the calculus is a well-known topic, as are his attempts to build a brand-new geometry based on sensible minima, but the notion of a Berkeleian mathematical philosophy has hardly been examined. Some recent works have nevertheless tried to analyze what this philosophy could be.

This paper deals with Hume’s theory of causation and his two definitions of cause. Hume’s theory of causation is based on the notions of priority, contiguity, constant conjunction and necessary connexion. The first problem is whether, according to Hume, necessary connexion is a basic part of causation. As Beebee claims, there are three distinct interpretations of Hume’s theory. The traditional interpretation claims that, according to Hume, there are only regular successions of events and necessary connexion or powers are incoherent part (...) of causation. According to projectivism, necessary connexion is an additional component that we project into the causation. Sceptical realism claims that Hume was a sceptic about knowing the real nature of powers but he believed that they exist in the external world. The second problem is whether projection or belief in necessary connexion is able to solve the problem of spurious causes. All three interpretations claim that we cannot know anything about powers or necessary connexion of events. The main goal of this paper is to argue that these interpretations cannot solve the problem of spurious causation. The Humean theory of causation is reduced only to the regular succession of events.

For the last 30 years I have been writing a trilogy on Locke’s, Berkeley’s, and Hume’s philosophies of money. With the publication of Clipped Coins. Abused Words and Civil Government; John Locke’s Philosophy of Money and Exciting the Industry of Mankind; George Berkeley’s Philosophy of Money and with the last volume on Hume in preparation, the trilogy is now almost completed.

I present Aristotle’s theory of causation in a way that privileges a comparison with contemporary discussion on causation. I do so by selecting in Aristotle’s theory points that are interesting to contemporary discussion and by translating Aristotle in the contemporary philosophical terminology. I compare Aristotle’s views with Mackie’s (1993/1965) and Sosa’s (1993/1980). Mackie is a humean regularist regarding the metaphysics of causal necessity, but his theory postulates some formal aspects of the causal relation which are similar to the Aristotelian theory. (...) By introducing the notion of causal field as a third causal relatum – a sample in which the cause must be picked out as a explanation coextensive to the effect –, Mackie holds a point very similar to Aristotle, inasmuch as both defend that the causal relation is triadic and both have the extensional desideratum. Sosa (1993/1980) defends that every cause necessitates its effect, arguing against classical Humeanism, and he also proposes a causal pluralism. Both these theses are clearly Aristotelian. Aristotle comprehends that the causal relation has three relata: a subjacent C, a property of that subjacent A and a cause B that explains why such property is attributed to that subjacent. The subjacent is similar to Mackie’s notion of causal field, for in regard to it the cause must be coextensive to the property. But Aristotle also says that for each explanandum (property attributed to a subjacent of which one aims to investigate a cause) there is only one cause, which necessitates it. Sosa and Aristotle are similar because both develop a causal pluralism from a theory of causes as having intrinsic necessitation. For Aristotle, causes/explanations [aitiai] are central for attaining scientific knowledge, and its triadic structure determines the syllogistic structure of scientific demonstrations. Aristotle’s theory of causation also involves comprehending the actualisation of capacities (dispositional properties of objects) affirming that the causal relation is resultant from intrinsic properties of the objects, and the cause B is the essence of the explanandum.
