This research draws from three distinct lines of research on the link between emotions and intergroup bias as springboard to integrative, new hypotheses. Past research suggests that emotions extrinsic to the outgroup (or “incidental”), and intrinsic to the outgroup (or “integral”), produce valence-congruent effects on intergroup bias when relevant or “applicable” to the outgroup (e.g., incidental/integral anger and ethnic outgroups). These emotions produce valenceincongruent effects when irrelevant or “non-applicable” to the outgroup (e.g., incidental/integral sadness and happiness, and ethnic outgroups). Internally (...) valid and ecologically sound tests of these contrasting effects are missing; hence we examined them experimentally in meaningful settings of interethnic contact. To this end, we hybridized established research paradigms in mood and intergroup contact research; this approach enabled us to use same materials and induction methods to instigate incidental and integral emotions in a single research design. In Experiment 1, White Australian students (N= 93) inin vivoreal face-to-face contact with an ethnic tutor in their classroom displayed less interethnic bias when incidentally sad (vs. happy) or integrally happy (vs. sad). In Experiment 2, White American males' (N= 492) anti-Arab bias displayed divergent effects under incidental vs. integral (non-applicable) sadness/happiness and similar effects under incidental vs. integral (applicable) anger. The role of perceptions of agency in the emotion-inducing situation is also explored, tested, and explained drawing from mainstream emotion theory. As expected, integral and incidentalapplicableemotions caused valence congruent effects, at the opposite sides of the subjective agency spectrum, by encouraging the generalization of dislike from the outgroup contact partner to the outgroup as a whole. On the other hand, incidental-non-applicable emotions caused valence-incongruent effects on bias, under high agency conditions, by encouraging (non-partner-centered) heuristic processing. Because of the improved methodology, these effects can be regarded as genuine and not the byproduct of methodological artifacts. This theory-driven and empirically sound analysis of the interplay between emotion source, emotion applicability and subjective agency in intergroup contact can increase the precision of emotion-based bias reduction strategies by deepening understanding of the emotion conditions that lead to intergroup bias attenuation vs. exacerbation.

In this paper, I shall try to present and defend some arguments against naturalistic evolutionism that are partly inspired by A. Plantinga’s well-known evolutionary argument against naturalism. I give two different characterizations of naturalistic evolutionism: according to the first, it is the view for which, for every human activity, that activity is governed by adaptive functions and nothing else ; according to second, it is the view for which, for most human activities, those activities are governed by adaptive functions and (...) nothing else. Both versions of naturalistic evolutionism fall in trouble when they have to ground the truth of metaphysical beliefs, even including the beliefs that N.E.1, that N.E.2, that N.E.1 is true and that N.E.2 is true. Thus, it seems either that naturalistic evolutionism is false and self-defeating or that its defense is a huge metaphysical task to undertake than one could expect. (shrink)

What this chapter labels "the naïve view of powers" roughly holds that there is a strict correspondence between powers, their bearers, manifestations and activations, on one hand, and causal processes and their causes and effects, on the other hand. The naïve view of powers seems to run afoul of the possibility that powers compose. Therefore, most power theorists are inclined to reject it. This chapter develops an account of the composition of powers that can actually preserve the naïve view of (...) powers. First, the naïve view is introduced. Then five cases of composition are examined, and it is briefly shown how such cases have led many philosophers to reject the naïve view (or some relevant portion of it). This is followed by an account of the composition of powers. This account is grounded on a distinction between component and derivative powers and on certain dependence relations holding between the latter and the former. This account is able to deal with the cases of composition presented and preserve the naïve view of powers. Finally, some objections and replies are anticipated. This chapter deals with the threat of overdetermination and (briefly) with the distinction between component and resultant forces-which is orthogonal to that between component and derivative powers.

I wish to prove in this article that Thomas Aquinas was a metaontological pluralist, i.e., that he held that there are many, non-equivalent and irreducible dependence relations in the universe. In this respect, I shall focus on Aquinas' doctrine of the four causes and on the dependence relationships between matter and form in material substances. Subsequently, I shall also reconstruct Aquinas' doctrines by explicitly appealing to metaontological pluralism. I shall explore two routes towards Aquinas' metaontological pluralism: one based on cases (...) of apparent mutual dependence and the other based on the asymmetry of natural priority. Finally, I shall provide two original interpretations of the doctrine of the four causes and of the dependence relationships between matter and form. Such interpretations will be based on the metaphysics of powers. In Section 1 I shall introduce metaontological pluralism and the two routes. In Section 2 I shall examine Aquinas' doctrine of the four causes. In Section 3 I shall provide an interpretation of that doctrine based on powers. In Section 4 I shall consider the dependence relationships between matter and form in material substances. In Section 5 I shall provide an interpretation of such relationships based on powers.

A linear space is a system of points and lines such that any two distinct points determine a unique line; a Steiner k-system is a linear space such that each line has size exactly k. Clearly, as a two-sorted structure, no linear space can be strongly minimal. We formulate linear spaces in a vocabulary $\tau $ with a single ternary relation R. We prove that for every integer k there exist $2^{\aleph _0}$ -many integer valued functions $\mu $ such that (...) each $\mu $ determines a distinct strongly minimal Steiner k-system $\mathcal {G}_\mu $, whose algebraic closure geometry has all the properties of the ab initio Hrushovski construction. Thus each is a counterexample to the Zilber Trichotomy Conjecture. (shrink)

We summarize in this introduction the contents of all the contributions included in Synthese special issue on form, structure and hylomorphism. Moreover, we provide an exhaustive bibliography of recent research on these topics.

At least since Russell, mainstream analytic philosophy has distinguished internal and external relations and acknowledged the existence of both. This seems in line with both the manifest and scientific images of the world. However, there is a recent deflationary trend about relations, which focuses on the truthmakers of relational statements in order to show that putative external relations are in fact internal, and that internal relations do not really exist. Lowe’s posthumous 2016 paper is a thorough presentation of this line (...) of thought. This article critically analyzes Lowe’s arguments in that paper, and some related arguments in recent works. It finds them wanting and thus reaffirms the irreducible reality of relations. (shrink)

A logical approach to Bell's Inequalities of quantum mechanics has been introduced by Abramsky and Hardy [2]. We point out that the logical Bell's Inequalities of [2] are provable in the probability logic of Fagin, Halpern and Megiddo [4]. Since it is now considered empirically established that quantum mechanics violates Bell's Inequalities, we introduce a modified probability logic, that we call quantum team logic, in which Bell's Inequalities are not provable, and prove a Completeness Theorem for this logic. For this (...) end we generalise the team semantics of dependence logic [7] first to probabilistic team semantics, and then to what we call quantum team semantics. (shrink)

I shall introduce at the beginning of the paper a characterization of strong ontological emergence. According to it, roughly, something strongly emerges from some other thing iff the former depends in some respect on the latter and it some independent of it in some other respect. Afterwards, I shall present my own formulation of strong emergence, which is based on the distinction between the mere possession and the activation of a causal power. Causal powers are the entities to be primarily (...) taken as emergent. Emergent causal powers depend for their possession on their emergence bases, but they are also independent of the latter for their activation. This claim will be defended within some more general assumptions about the metaphysics of powers. Finally, I shall compare the power-based formulation of emergence with other formulations. I shall try to demonstrate that the power-based formulation is metaphysically less controversial than the other formulations. For the power-based formulation does not need to defend the additional thesis that the emergents can depend in some relevant respect on their bases and be independent of the latter in some other relevant respect. Indeed, the distinction between the mere possession and the activation of a power is inscribed in the nature of powers themselves. (shrink)

The Quest for Emergence is a comprehensive philosophical introduction to emergence. It includes the illustration and discussion of the major varieties of emergentism. The book also introduces many scientific examples of emergence and all the problems and objections affecting emergentism. In the introduction, the author provides a characterization of emergence and of some key distinctions: for example, the one between weak and strong emergence. The second chapter contains a short history of British Emergentism. The configurational forces objection against emergentism is (...) also discussed. In the third chapter, some cases of weak and strong emergence taken from different scientific disciplines are described in an accessible and informal language. Emergence is considered in physics, chemistry, biology, the neurosciences and informatics, psychology, sociology and economics. In the fourth chapter, the worst enemy of emergentists is introduced: micro-physicalism. All the problems and objections against emergentism are presented and discussed, including Jaegwon Kim’s arguments. After having recalled in the fifth chapter all the desiderata a good emergentist theory should be able to satisfy and all the problems it should be able to solve, the author devotes the sixth chapter to examining many current varieties of emergentism. Finally, in the seventh chapter, he draws a sketch of his own emergentist theory, which is based on two ideas: emergence primarily concerns powers; emergents exercise downward causation through formal influence.

I shall explore in this article the hypothesis that structures are relations between the components of complex entities. After having introduced hylomorphism, its major advantages and the major views of the nature of structures, I shall introduce the distinctions between external and internal relations and the one between symmetrical and non-symmetrical relations. I shall also describe the theory of non-symmetrical relations that I accept, i.e., the O-Roles theory, as most structures seem to be external and non-symmetrical relations. Later on, I (...) shall develop my hypothesis and I shall deal with one objection, i.e., that relations necessarily come together with Bradley's vicious regress. Finally, I shall also hypothesize that complex entities are different from structures and from their structured components. In this respect, I shall defend a " simple view " of complex entities. Dwelling on this view, I shall also reply to some recent objections against hylomorphism. (shrink)

I examine and discuss in this paper Orilia’s theory of external, non-symmetrical relations, that is based on ontological roles (O-Roles). I explore several attempts to interpret O-Roles from an ontological viewpoint and I reject them because of two problems concerning the status of asymmetrical relations (to be distinguished from non-symmetrical relations simpliciter) and of exemplification as an external, non-symmetrical relation. Finally, following Heil’s and Lowe’s characterization of modes as particular properties that ontologically depend on their “bearers”, I introduce relational modes (...) in order to define a new solution to the problems of the ontological status of both external, non-symmetrical relations and O-Roles. I also deal with five objections raised by Fraser MacBride against relational modes and O-Roles and I elaborate an analysis of the relations of being to the left of and being to the right of. (shrink)

I shall explore in this article the metaphysical possibility of powers’ strongly emerging from relations. After having provided a definition of emergent powers that is also based on the distinction between the possession and the activation of a power, I shall introduce different sorts of Relations that Ground Emergence, both external and internal. Later on, I shall discuss some examples of powers that are grounded on their instantiation. Finally, I shall examine the consequences of accepting such relations within a physicalistic (...) ontology and I shall defend them against two objections based on the notion of bruteness. (shrink)

I defend the thesis that, if there are substances, substance causation (i.e., causation by substances) is the only sort of causation in the universe – or the only fundamental sort. Subsequently, I develop an account of substance causation that is partly grounded on a peculiar interpretation of absolute change (i.e., of entities' coming and ceasing to be) and qualitative change, on some ontological assumptions about modes (i.e., individual properties that ontologically depend on their bearers) and powers. Finally, I reply to (...) some objections against substance causation in general (e.g., C. D. Broad's objection against causes' being non-essentially-dated entities) and to some possible objections against my own account and I briefly explore three advantages given by the acceptance of the latter. (shrink)

In this paper I consider respects of dependence, namely, the fact that some entities depend on other entities in some respect or another. In the first section, I provide a characterization of contemporary debates on dependence based on respects of dependence. I also single out seven desiderata a good theory of dependence should satisfy and three ways of interpreting respects of dependence. In the second section, I criticize two such ways and, in the third section, I defend the remaining option, (...) namely, that respects of dependence correspond to different dependence-relations between entities. In the fourth section, I develop my theory of Respect-of-Dependence Relations in order to distinguish between partial and full dependence and between specific and generic dependence, and to qualify RD -relations in temporal and modal terms. Finally, in the last section, I anticipate and reply to three objections against dependence pluralism. (shrink)

Masks, interferers, finks, reverse finks, and mimickers are troublesome for powers metaphysics insofar as the latter concedes that there are powers with essential stimuli/activation conditions. In this article, I aim at offering a novel approach for solving this problem. In Section 1, I shall present the problem; and in Section 2, I shall briefly show how it also arises within non‐reductive views of powers. Subsequently, in Section 3, I shall examine the failure of the ceteris paribus solution. The pars construens (...) will begin in Section 4, where I shall distinguish between the activation conditions, the background conditions, and the possession conditions of a power. Within each category, I shall draw further distinctions. In Section 5, I shall demonstrate how such distinctions may ground a solution to our problem. Finally, in Section 6, I shall anticipate and reply to four objections. (shrink)

Emergence is intuitively characterized as dependent novelty. Yet, besides this intuition, several formulations of it were elaborated in the last decades. In this article, after having distinguished between two different varieties of emergence, I aim at providing two formulation schemes for emergence. This could help to explain what emergence is and to clarify and unify the suggested formulations. The general idea behind my schemes is that emergence is partial and qualified dependence of the emergent entities on their emergence bases. After (...) having examined several formulations of emergences and presented my schemes, I shall analyse two interesting consequences of the acceptance of the latter: the in principle compatibility between weak and strong emergence and the idea that micro-physicalism, i.e., the main competitor of emergentism, may actually come in different degrees of strength, more or less in contrast with emergentism. Eventually, I shall briefly compare my formulation schemes with some other relevantly similar proposals. (shrink)

I put in question in this article the existence of conjunctive properties. In the second section, after having provided a characterization of conjunctive properties, I develop an argument based on the principle of ontological parsimony: if we accept that there are conjunctive properties in the universe then, ceteris paribus, our ontology turns out to be less ontologically parsimonious than if we reject them. Afterwards, in the third section, I distinguish between maximalist and non-maximalist and reductionist and non-reductionist theories of conjunctive (...) properties., as well as between reductionist and non-reductionist theories that reject conjunctive properties. Such distinctions help to clarify the options at hand when accepting or rejecting conjunctive properties. In light of these distinctions, I then tackle two objections against the argument from ontological parsimony. Finally, in the remaining sections, I deal with two arguments defended by D. M. Armstrong for the existence of conjunctive properties: the argument from infinite complexity and the argument from causal powers. I show that there are several ways to resist these arguments and their conclusion. (shrink)

We use sets of assignments, a.k.a. teams, and measures on them to define probabilities of first-order formulas in given data. We then axiomatise first-order properties of such probabilities and prove a completeness theorem for our axiomatisation. We use the Hardy–Weinberg Principle of biology and the Bell’s Inequalities of quantum physics as examples.

Within some ontological theories, bare or thin particulars are the “kernel” of ordinary substances and they are supposed to clarify some key features of the latter, including their nature. In this article, I wish to offer a new theory of bare particulars, based on an interpretation of properties as modes and on a new reading of the dependence relations holding among entities in terms of respects of dependence. In Section 1, I shall introduce bare particulars, modes and respects of dependence. (...) In Section 2, I shall consider the relationships between bare particulars, clothed particulars (i.e., ordinary substances) and their properties. I shall present two models and I shall examine some of their problems. In Section 3 and in Section 4, I shall present a new model by invoking modes and respects of dependence. This will ground my theory of the relationships between bare particulars, clothed particulars and their properties. Finally, in Section 5, I shall compare my model with the second model presented in Section 2 and, in Section 6, I shall deal with some objections against bare particulars and against my own theory. (shrink)

In this paper I shall “draw” a sketch of a version of Meinongian Presentism. After having briefly presented some data that presentists need to explain and three problems that typically affect presentism (the triviality objection, the problem of the reference of true propositions’ constituents that seem to involve merely past and merely future objects, the truthmaking problem), I shall clarify the bases of my theory. First, I shall reject the actualist presentist assumption, according to which there are no things that (...) do not exist now. Secondly, I shall introduce some notions (e.g., the ones of tensed properties and of temporal existence) that will be useful in order to clarify the contrast between eternalist and non-eternalist metaphysical theories of time. Thirdly, I shall define Meinongian Presentism. Finally, I shall try to demonstrate that this version can deal with the aforementioned problems and with the presentist data in a serious and perspicuous way. (shrink)

I develop and defend a model of downward causation denoted as downward, structural, substance causation. This model is based on the idea that higher-level, strongly emergent substances can cause something at lower levels by imposing certain structures on lower-level goings-on. After providing a sketch of the model and of its ontological assumptions, I apply it to the analysis of how free mental causes can structure neural goings-on. I defend three theses following from such an analysis, and I test the empirical (...) plausibility of the model. Finally, I anticipate some objections and replies. (shrink)

I shall defend in this paper the thesis that, if there are irreducible powers such as the power to produce a certain object (generative powers), then there are objects that do not exist and they are part of the fundamental level of the universe. Thus, generative powers come together with Meinongianism. After having clarified my argument, I shall examine and criticize Armstrong (1997)’s attempt to reduce powers to other sorts of entities. Finally, I shall deal with five accounts of generative (...) powers that are somehow alternative to Meinongianism and with some (more general) miscellaneous concerns about the truth of this doctrine.

Downward causation plays a fundamental role in many theories of metaphysics and philosophy of mind. It is strictly connected with many topics in philosophy, including but not limited to: emergence, mental causation, the nature of causation, the nature of causal powers and dispositions, laws of nature, and the possibility of ontological and epistemic reductions. _Philosophical and Scientific Perspectives on Downward Causation_ brings together experts from different fields—including William Bechtel, Stewart Clark and Tom Lancaster, Carl Gillett, John Heil, Robin F. Hendry, (...) Max Kistler, Stephen Mumford and Rani Lill Anjum—who delve into classic and unexplored lines of philosophical inquiry related to downward causation. It critically assesses the possibility of downward causation given different ontological assumptions and explores the connection between downward causation and the metaphysics of causation and dispositions. Finally, it presents different cases of downward causation in empirical fields such as physics, chemistry, biology and the neurosciences. This volume is both a useful introduction and a collection of original contributions on this fascinating and hotly debated philosophical topic. (shrink)

In this article, I aim at showing how powers may ground different types of probability in the universe. In Section 1 I single out several dimensions along which the probability of something can be determined. Each of such dimensions can be further specified at the type-level or at the token-level. In Section 2 I introduce some metaphysical assumptions about powers. In Section 3 I show how powers can ground single-case probabilities and frequency-probabilities in a deterministic setting. Later on, in Section (...) 4, I move to a theoretical framework where the falsity of determinism is assumed. Within such a framework, I first argue that some probabilities are grounded on basic powers. Moreover, in Section 5, I introduce tendencies and suggest that they are endowed with specific degrees of activation that may change over time. Such degrees explain why tendencies are more likely to be activated than non-activated, or vice versa. In Section 6 I compare my account of tendencies with other accounts. Finally, in Section 7, I anticipate some general objections against my account – objections that it shares with propensity-accounts of probability – and against degrees of activation of tendencies. (shrink)

I shall argue in this article that, if we need to admit of negative facts in our ontology as falsemakers of false propositions, then it is plausible to accept that there are also negative properties conceived of as modes. After having briefly recalled the falsemaker argument, I shall explore five different alternative interpretations of negative facts and I shall demonstrate that each alternative – except for the one involving negative properties – is affected by some problems. Later on, I shall (...) deal with a number of objections against negative properties and I shall demonstrate that they can be overcome without much difficulty. Eventually, I shall tackle Nick Zangwill's argument against the thesis that negative properties are as real as positive ones. Among other things, I shall argue that Zangwill's argument is at least limited in its scope, since it only works with negative and positive determinates within some common determinable. (shrink)

We prove that every quasi-Hopfian finitely presented structure _A_ has a _d_- \(\Sigma _2\) Scott sentence, and that if in addition _A_ is computable and _Aut_(_A_) satisfies a natural computable condition, then _A_ has a computable _d_- \(\Sigma _2\) Scott sentence. This unifies several known results on Scott sentences of finitely presented structures and it is used to prove that other not previously considered algebraic structures of interest have computable _d_- \(\Sigma _2\) Scott sentences. In particular, we show that every (...) right-angled Coxeter group of finite rank has a computable _d_- \(\Sigma _2\) Scott sentence, as well as any strongly rigid Coxeter group of finite rank. Finally, we show that the free projective plane of rank 4 has a computable _d_- \(\Sigma _2\) Scott sentence, thus exhibiting a natural example where the assumption of quasi-Hopfianity is used (since this structure is not Hopfian).

Mechanisms are organized collections of objects and activities that underlie certain phenomena/behaviours. In this article, I shall argue that the organizations of mechanisms should be thought of as external relations, namely, as relations that do not entirely depend on their relata’s existence, nor on their natures, nor on their intrinsic properties. After having introduced in the first two sections mechanisms and the ontology of relations, I shall analyse the organizations of mechanisms along four different dimensions: spatial, temporal, causal and hierarchical. (...) I shall demonstrate that each dimension requires that organizations be taken as external relations. Finally, in the last section, I shall anticipate and reply to two objections. (shrink)

The author argues for the existence of negative facts. The first section is devoted to an argument, grounded on truthmaker maximalism, that aims at demonstrating that negative facts must exist at least as false propositions’ falsemakers. In the second section, the author analyzes and criticizes several attempts to get rid of negative facts: the ones based on incompatibilities, absences, totality facts and polarities, as well as the ones based on various restrictions on truthmaker maximalism or on the non-acceptance of facts (...) as truthmakers. In particular, it is shown that an ontology that accepts negative facts is simpler than an ontology that denies their existence and that in general, many attempts to get rid of negative facts turn out to recognize the existence of such entities or of entities that are more mysterious than negative facts themselves. (shrink)

I offer in this article an account of the distinction between intrinsic and extrinsic properties based on the ontology of modes. Modes are particular properties that directly depend for their identity on their "bearers". In Section 1, I shall introduce the ontology of modes. In Section 2, I shall examine the problem of distinguishing between intrinsic and extrinsic properties by considering another, related problem: that of distinguishing between internal and external relations. In Section 3, I shall present my own account (...) and I shall also single out different degrees of intrinsicality and extrinsicality. In Section 4, I shall deal with missing-relatum modes, namely, with modes that lack specific relata, such as Othello's loving someone. I shall introduce three different theories to deal with them. Finally, in Section 5, I shall solve some problems affecting the intrinsic/extrinsic distinction from the standpoint of my account. (shrink)

I introduce functional powers, i.e., causal powers that play the role of functions. In the first section, I characterize functions and present some desiderata for a good theory of functions. In the second section, I make some assumptions about the ontology of powers, teleology and structures-that will be helpful in order to ground my account of functional powers. In the third section, sixteen different types of functional powers are examined. All such types of functional powers will exhaustively contribute to performing (...) all the ontological and explanatory tasks that may be attributed to functions. Finally, in the fourth section, it is shown how my account of functions as functional powers satisfies all the desiderata presented at the outset. (shrink)

Neo-Aristotelian views of goodness hold that the goodness of something is strictly connected with its goal(s). In this article, I shall present a power-based, Neo-Aristotelian view of goodness. I shall claim that there are certain powers (i.e., Goodness-Conferring Powers, or GC-powers in short) that confer goodness upon their bearers and upon the resulting actions. And I shall suggest that GC-powers are strongly teleological tendencies. In Section 1, I shall present the kernel of Neo-Aristotelian conceptions of goodness. In Section 2, I (...) shall introduce strongly teleological powers and tendencies. In Section 3, GC-powers will be characterized. I shall also examine a number of options with regard to their number and features and how to single out their goodness value. In Section 4, I shall focus on good agents and on three distinct ways in which they may be good: tendential goodness, actual goodness, and purely actual goodness. Relatedly, among the actions connected with a certain GC-power, I shall also distinguish between primary and secondary actions and between pure and impure actions. In Section 5, good actions will be examined. Actions may be good in three distinct ways. Indeed, actions may be endowed with primary goodness, secondary goodness and preventative goodness. In Section 6, I shall face the remaining problems. (shrink)

Law dispositionalism is the doctrine according to which laws of nature are grounded on powers/dispositions. In this article, I shall examine how certain laws of nature can turn out to be contingent on this view. First of all, I shall distinguish between two versions of law dispositionalism (i.e., a weak and a strong one) and I shall also single out two further theses that may be conjoined with it (i.e., strong and weak dispositional essentialism). I shall then define four different (...) sorts of laws of nature. Afterwards, I shall examine five sources of contingency for law dispositionalism: the contingent existence of the relevant entities involved in the laws; the contingent activation, background and possession conditions of the powers at stake; the presence of contingent constants in the laws; the presence of indeterministic powers; the presence of powers that are not essential to the entities involved in the laws.

We prove that the form of conditional independence at play in database theory and independence logic is reducible to the first-order dividing calculus in the theory of atomless Boolean algebras. This establishes interesting connections between independence in database theory and stochastic independence. As indeed, in light of the aforementioned reduction and recent work of Ben-Yaacov :957–1012, 2013), the former case of independence can be seen as the discrete version of the latter.

We continue the work on the relations between independence logic and the model-theoretic analysis of independence, generalizing the results of [15] and [16] to the framework of abstract independence relations for an arbitrary AEC. We give a model-theoretic interpretation of the independence atom and characterize under which conditions we can prove a completeness result with respect to the deductive system that axiomatizes independence in team semantics and statistics.

I shall present in this article a double negation account of the distinction between causes and background conditions. Such an account will be based on the idea that, unlike causes, background conditions allow for certain effects by way of double prevention. In Section 1 I shall introduce objective and non-objective theories of the causes-background conditions distinction and I shall discuss and reject some non-objective theories. In Section 2 I shall examine some existing objective theories and argue that they need to (...) be supplemented in two relevant respects. In Section 3 I shall present my double negation account. Background conditions will be taken to allow for their effects by acting as early double preventers, late double preventers or effect double preventers. In Section 4 I shall deal with two main problems, i.e., the possibility of interpreting background conditions as purely indirect causes and the introduction of negative entities in my account, and with further issues.
