According to Husserl, Hume’s empirical method was deeply flawed—like all empiricists, Hume did not, and could not adequately justify his method, much less his findings. Instead, Hume gives us a “circular” and “irrational” “psychological explanation” of “mediate judgments of fact,” i.e. of inductive inferences. Yet Husserl was certain that he could justify both his own method and his own findings with an appeal to the phenomenological, pre-theoretical, pre-naturalistic “epoché”. However, whether or not Husserl’s notion of an epoché is justified, or (...) even viable, is not our focus here. Rather, our issue is with Hume, particularly: How could Hume have responded? In this paper, I show that in Book I of the Treatise, Hume did—however implicitly—appeal to a “pre-theoretical” notion of belief, which meets Husserl’s demands for a pre-theoretical grounding, i.e. a justificatory grounding. And so, his method is, at least in this respect, justified. But this belief is by no means “prenaturalistic.” Rather, it is a function of empirical data. In particular, it is a product of the “constant and coherent” impressions that seem to naturally obtain of experience. As a result, Hume’s method, which, in agreement with Husserl, we may characterize as psychology, does admit of a certain degree of regularity, but an empirical regularity. And according to Hume, contra Husserl’s complaints, this is the best that we can hope for; regularity will have to suffice, not certainty. However, it must be noted up front that this justification is implicit—Hume is not nearly as forthright as he could have been. Thus, making his position more explicit is the task of this paper. I am not presenting my own position, where I offer my own arguments. Instead, I present textual evidence, contextualized with ample explication. It is my hope that by doing so, Hume may more effectively make his case. (shrink)

There are some necessary conditions on causal relations that seem to be so trivial that they do not merit further inquiry. Many philosophers assume that the requirement that there could be no temporal gaps between causes and their effects is such a condition. Bertrand Russell disagrees. In this paper, an in-depth discussion of Russell’s argument against this necessary condition is the centerpiece of an analysis of what is at stake when one accepts or denies that there can be temporal gaps (...) between causes and effects. It is argued that whether one accepts or denies this condition, one is implicated in taking on substantial and wide-ranging philosophical positions. Therefore, it is not a trivial necessary condition of causal relations and it merits further inquiry. (shrink)

State of art paper on the topic causation, around the problem of the nature of causation. Central theories of contemporary philosophical literature are discussed and analysed, namely, regularity theories of Hume and Mackie, counterfactual theories of Lewis, probabilistic theories of Reichenbach, Lewis and Menzies and causal processes theories of Salmon and Dowe.

Minimally, causal realism (as understood here) is the view that accounts of causation in terms of mere, regular or probabilistic conjunction are unsatisfactory, and that causal phenomena are correctly associated with some form of de re necessity. Classic arguments, however, some of which date back to Sextus Empiricus and have appeared many times since, including famously in Russell, suggest that the very notion of causal realism is incoherent. In this paper I argue that if such objections seem compelling, it is (...) only because everyday expressions concerning causal phenomena are misleading with respect to certain metaphysical details. These expressions generally make reference to the relations of events or states of affairs, but ignore or obscure the role played by causal properties. I argue that on a proposed alternative, an analysis in terms of causal processes, more refined descriptions of causal phenomena escape the charge of incoherence. Causal necessity is here located in the relations of causal properties. I distinguish this view from the recent process theories of Salmon and Dowe, which are disinterested in causal realism.

Hume frequently states that we are ignorant of genuine power. There is a well-known internal difficulty concerning this claim concerning ignorance. According to Hume, we do not have an impression-based idea of genuine power; on the other hand, every noun needs a corresponding idea to be meaningful. Is his claim concerning ignorance, which makes use of the noun ‘power’, meaningless in light of his own criterion of meaningfulness? I focus on two exegetical approaches to this difficulty proposed in the literature (...) of the ‘New Hume Debate’: 1) we may read Hume's own positive definitions of power back into his claim of ignorance to ensure the meaningfulness of ‘power’; and 2) ‘power’ may correspond to a relative idea of genuine power and derive its meaning from this relative idea. I argue against both of these solutions and offer my own solution that is quite close to the text. However, adopting my proposal demands a price: a considerable part of Hume's argumentative undert..

Backtracking influence is influence that zigzags in time. For example, backtracking influence exists when an event E_1 makes an event E_2 more likely by way of a nomic connection that goes from E_1 back in time to an event C and then forward in time to E_2. I contend that in our local region of spacetime, at least, backtracking influence is redundant in the sense that any existing backtracking influence exerted by E_1 on E_2 is equivalent to E_1's temporally direct (...) influence on E_2. I prove the redundancy of backtracking influence using several plausible physical principles without assuming any fundamental temporal or causal asymmetry. This explanation can play a prominent role in an account of why causation appears to be objectively asymmetric regardless of whether the fundamental laws are symmetric. (shrink)

Questions about the metaphysics of causation may be usefully divided as follows. First, there are questions about the nature of the causal relata, including (1.1) whether they are in spacetime immanence), (1.2) how fine grained they are individuation), and (1.3) how many there are adicity). Second, there are questions about the metaphysics of the causal relation, including (2.1) what is the difference between causally related and causally unrelated sequences connection), (2.2) what is the difference between sequences related as cause to (...) effect, and those related as effect to cause or as joint effects of a common cause direction), and (2.3) what is the difference between sequences involving the cause, and those involving mere conditions selection).

Essence and causation are fundamental in metaphysics, but little is said about their relations. Some essential properties are of course causal, as it is essential to footprints to have been caused by feet. But I am interested less in causation's role in essence than the reverse: the bearing a thing's essence has on its causal powers. That essencemight make a causal contribution is hinted already by the counterfactual element in causation; and the hint is confirmed by the explanation essence offers (...) of something otherwise mysterious, namely, how events exactly alike in every ordinary respect, like the bolt'ssuddenly snapping and its snapping per se, manage to disagree in what they cause. Some prior difference must exist between these events to make their causal powers unlike. Paradoxically, though, it can only be in point of a property, suddenness, which both events possess in common. Only by postulating a difference in themanner — essential or accidental — of the property's possession is the paradox resolved. Next we need an account of causation in which essence plays an explicit determinative role. That account, based on the idea that causes should becommensurate with their effects, is thatx causesy only if nothing essentially poorer would have done, and nothing essentially richer was needed.

This paper examines the Transference Theory of causation, developed originally by Aronson (1971) and Fair (1979). Three difficulties for that theory are presented: firstly, problems associated with the direction of transference and causal asymmetry; secondly, the case of persistence as causation, for example where a body's own inertia is the cause of its motion; and thirdly the problematic notion of identity through time of physical quantities such as energy or momentum. Finally, the theory is compared with the Conserved Quantity Theory (...) (Dowe 1992c), and it is shown that that account embodies the modifications that the transference theory needs to adopt.

In this paper we defend the view that the ordinary notions of cause and effect have a direct and essential connection with our ability to intervene in the world as agents.1 This is a well known but rather unpopular philosophical approach to causation, often called the manipulability theory. In the interests of brevity and accuracy, we prefer to call it the agency theory.2 Thus the central thesis of an agency account of causation is something like this: an event A is (...) a cause of a distinct event B just in case bringing about the occurrence of A would be an effective means by which a free agent could bring about the occurrence of B. In our view the unpopularity of the agency approach to causation may be traced to two factors. The first is a failure to appreciate certain distinctive advantages that this approach has over its various rivals. We have drawn attention to some of these advantages elsewhere, and we summarize below. However, the second and more important factor is the influence of a number of stock objections, objections that seem to have persuaded many philosophers that agency accounts face insuperable obstacles. In this paper we want to show that these objections have been vastly overrated. There are four main objections. (shrink)

The purpose of this essay is to defend the deductive-nomological model of explanation against a number of criticisms that have been made of it. It has traditionally been thought that scientific explanations were causal and that scientific explanations involved deduction from laws. In recent years, however, this three-fold identity has been challenged: there are, it is argued, causal explanations that are not scientific, scientific explanations that are not deductive, deductions from laws that are neither causal explanations nor scientific explanations, and (...) causal explanations that involve no deductions from laws. The aim of the present essay is to defend the traditional identities, and to show that the more recent attempts at invalidating them fail in their object. More specifically, this essay argues that a Humean version of the deductive-nomological model of explanation can be defended as the correct account of scientific explanation of individual facts and processes, and as the correct account of causal explanations of individual facts and processes. The deductive-nomological model holds that to explain an event E, say that a is G, one must find some initial conditions C, say that a is F, and a law or theory T such that T and C jointly entail E, and both are essential to the deduction.

According to the standard view, the causal process connecting a past representation and its subsequent recall involves intermediary memory traces. Yet Bertrand Russell and Ludwig Wittgenstein held that since the physiological evidence for memory traces isn't quite conclusive, it is prudent to come up with an account of memory causation-referred to as nmemic causation—that manages without the stipulation of memory traces. Given mnemic causation, a past representation is directly causally active over a temporal distance. I argue that the stipulation of (...) memory traces is indeed indispensable for analyzing mernory causation. (shrink)

Hume’s claim that a state is a belief is often intertwined---though without his remarking on this fact---with epistemic approval of the state. This requires explanation. Beliefs, in Hume’s view, are steady dispositions , nature’s provision for a steady influence on the will and action. Hume’s epistemic distinctions call attention to circumstances in which the presence of conflicting beliefs undermine a belief’s influence and thereby its natural function. On one version of this interpretation, to say that a belief is justified, ceteris (...) paribus, is to say that for all that has been shown the belief would be steady in its influence under suitable reflection. On a second version, it is to say that prima facie justification is an intrinsic property of the state, in virtue of its steadiness. These versions generate different understandings of the relationship between Parts iii and iv of Book I of the Treatise. (shrink)

In this paper I put forward a suggestion for identifying causality in micro-systems with the specific quantum field theoretic interactions that occur in such systems. I first argue — along the lines of general transference theories — that such a physicalistic account is essential to an understanding of causation; I then proceed to sketch the concept of interaction as it occurs in quantum field theory and I do so from both a formal and an informal point of view. Finally, I (...) present reasons for thinking that only a quantum field theoretic account can do the job — in particular I rely on a theorem by D. Currie and to the effect that interaction cannot be described in (a Hamiltonian formulation of) Classical Mechanics. Throughout the paper I attempt to suggest that the widespread scepticism about the ability of quantum theory to support a theory of causality is mistaken and rests on several misunderstandings.

The analyses of explanation and causal beliefs are heavily dependent on using probability functions as models of epistemic states. There are, however, several aspects of beliefs that are not captured by such a representation and which affect the outcome of the analyses. One dimension that has been neglected in this article is the temporal aspect of the beliefs. The description of a single event naturally involves the time it occurred. Some analyses of causation postulate that the cause must not occur (...) later than the effect. If we want this kind of causality it is easy to add the appropriate clause to ( CAUS ). An alternative is not to rule out backwards causation or causal loops a priori , but expect that ( CAUS ), via the properties of the contraction P C - , will result in the desired temporal relation between C and E . One way of ensuring this is to postulate that when the probability function P is contracted to P C - , the probabilities of all events that occurred before C remain the same in P C - as in P . This means that all beliefs about the history of events up to C are left unaltered in the construction of the hypothetical state of belief P C - . In conclusion, I hope to have shown that, in spite of these limitations, ( EXP ) and ( CAUS ) provide viable analyses of explanation and causality between single events for the case when epistemic states can be described by probability functions. I have also shown that the two analyses can be used to explicate the close connections between the two notions. These analyses reduce the problems of explanation and causality, hopefully in a non-circular way, to the problem of identifying contractions of states of belief. (shrink)

I argue for an interpretation of Hume on which our confused notions of causal necessity find their model in Hume's notion of logical necessity: our minds react in similar ways to constant conjunctions, on the one hand, and genuine cases of inseparability between ideas, on the other, in light of which we mistakenly place relations of necessitation between objects we call cause and effect. I argue that my account provides a more satisfying explanation of the mismatch between the feeling that (...) provides our true idea of necessary connection and the confused notions of necessary connection held by philosophers and the vulgar. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

And this paper is an attempt to say precisely how, thus addressing a philosophical problem which is commonly taken to be a serious one. It does so, however, in quite an idiosyncratic way. It is based on the account of inductive schemes I have given in (1988) and (1990a) and on the conception of causation I have presented in (1980), (1983), and (1990b), and it intends to fill one of many gaps which have been left by these papers. Still, I (...) have tried to make this paper self-contained. Section 1 explains the philosophical question this paper is about; in more general terms it asks what might be meant by objectifying epistemic states or features of them and to which extent epistemic states can be objectified. The next sections introduce the basis I rely on with formal precision and some explanation; section 2 deals with induction and section 3 with causation. Within these confines, section 4 attempts to give an explication of the relevant sense of objectification and section 5 investigates the extent to which various features of epistemic states are objectifiable. The two most salient results are roughly that the relation "A is a reason for B" cannot be objectified at all and that the relation "A is a cause of B" can be objectified only under substantial, though reasonable restrictions. What has all of this to do with probability? A lot. The paper trades on a pervasive duality between probabilistic and deterministic epistemology, between a probabilistic representation of epistemic states together with a theory of probabilistic causation and another representation of epistemic states which I call deterministic because it lends itself, in a perfectly parallel fashion, to a theory of deterministic causation. Here I explicitly deal only with the deterministic side, but the duality should pave the way for further conclusions concerning objective probabilities and statistical laws. This outlook is briefly expanded in the final section 6. (shrink)

Verificationism has often seemed attractive to philosophers because of its apparent abilityto deliver us from scepticism. However, I argue that purely epistemological considerationsprovide insufficient reason for embracing verificationism over realism. I distinguish twotypes of sceptical problem: those that stem from underdetermination by the actual data,and those that stem from underdetermination by all possible data. Verificationismevades problems of the second sort, but is powerless in the face of problems of the firstsort. But problems of the first sort are equally pressing. Furthermore, (...) there is some reasonto think that the two types of problem have a common origin. Thus the desire to avoidscepticism provides insufficient reason for adopting verificationism.

Since the mid-1970s, scholars have recognized that the skeptical interpretation of Hume's central argument about induction is problematic. The science of human nature presupposes that inductive inference is justified and there are endorsements of induction throughout "Treatise" Book I. The recent suggestion that I.iii.6 is confined to the psychology of inductive inference cannot account for the epistemic flavor of its claims that neither a genuine demonstration nor a non-question-begging inductive argument can establish the uniformity principle. For Hume, that inductive inference (...) is justified is part of the data to be explained. Bad argument is therefore excluded as the cause of inductive inference; and there is no good argument to cause it. Does this reinstate the problem of induction, undermining Hume's own assumption that induction is justified? It does so only if justification must derive from "reason", from the availability of a cogent argument. Hume rejects this internalist thesis; induction's favorable epistemic status derives from features of custom, the mechanism that generates inductive beliefs. Hume is attracted to this externalist posture because it provides a direct explanation of the epistemic achievements of children and non-human animals — creatures that must rely on custom unsupplemented by argument.

Is Hume a naturalist? Does he regard all or nearly all beliefs and actions as rationally unjustified? In order to settle these questions, it is necessary to examine their key terms and to understand the character-especially the normative character-of Hume's philosophical project. This paper argues that Hume is a naturalist-and, in particular, both a moral and an epistemic naturalist-in quite robust ways; and that Hume can properly regard many actions and beliefs as "rationally justified" in several different senses of that (...) term.

This chapter contains sections titled: Biography Philosophy.

In this book Martin Bunzl considers the prospects for a general and comprehensive account of explanation, given the variety of interests that prompt explanations in science. Bunzl argues that any successful account of explanation must deal with two very different contexts - one static and one dynamic. Traditionally, theories of explanation have been built for the former of these two contexts. That is to say, they are designed to show how it is that a 'finished' body of scientific knowledge can (...) be put to explanatory use. But finished sciences are few and far between. Real 'explanation' also occurs in a dynamical context in which questions are asked and answers are given as theories are in the process of being constructed. Here, Bunzl argues that attending to explanation produced under these dynamic circumstances undermines prominent features of the theory of explanation produced in the traditional static context.

This autobiographical sketch is being published 50 years after I started as an assistant professor at Georgetown University in 1970. In this presentation, I cannot tell the full story of these 50 years. I write only about the formative years both before and after I was hired at Georgetown, and I emphasize two subjects. The first is the importance of the individuals who were massive influences on my intellectual development and aspirations. The second is the great importance of multidisciplinary work. (...) I came from philosophy, a discipline that generally did not emphasize or particularly value multidisciplinary work, but I was transformed by individuals in other disciplines who directed me to this style of work. Almost sheer luck brought each of these influences into my life. (shrink)

Ziel der Arbeit ist zu zeigen, dass sich in der theoretischen Philosophie David Humes Ansätze zu einer therapeutischen Methode finden, wie sie von Ludwig Wittgenstein angewandt und beschrieben wurde. Im ersten Teil wird Wittgensteins Konzeption der Philosophie und ihre Anwendung anhand einer genauen Textexegese dargestellt. Der zweite Teil untersucht primär die Humeschen Überlegungen zu Kausalität und Induktion, seine methodologischen Aussagen sowie seine Perzeptionstheorie und argumentiert für die These, dass Hume ebenfalls, wenn auch mit Einschränkungen, Elemente einer therapeutischen Methode und eine (...) entsprechende Konzeption der Philosophie zugeschrieben werden können.
