Adolf Reinach belongs to the Brentanian lineage of Austrian Aristotelianism. His theory of social acts is well known, but his account of ownership has been mostly overlooked. This paper introduces and defends Reinach’s account of ownership. Ownership, for Reinach, is not a bundle of property rights. On the contrary, he argues that ownership is a primitive and indivisible relation between a person and a thing that grounds property rights. Most importantly, Reinach asserts that the nature ownership is not determined by (...) positive law but presupposed by it. Some have objected that such realism raises insuperable difficulties as to the origin of ownership, difficulties that could only be dealt with under a more conventionalist approach. I argue that the independence of the nature ownership from positive law is, in fact, compatible with the claim that its existence is dependent on human conventions. (shrink)

Philosophers have disagreed on the composition of force for decades. The main divergence concerns the fundamental question: given a certain motion that is observable, which force or forces are present in it, component or resultant forces? The present paper focuses on the conditions for dealing with this problem. I will argue that we are not able to infer force from the observation of a motion, as required by the problem. I will further argue that the validity of the Newtonian algorithm (...) is not a sufficient condition for that inference because the Gaussian algorithm, which is equally valid, differs from the former with regard to the forces present in motions. Under these circumstances, I will make recourse to an experiment available in physics in which the force present in a motion is measured. Thus, we obtain a numerical value for this force. This result, playing the role of a counterexample, clarifies the composition of force issue significantly. (shrink)

Do causes necessitate their effects? Causal necessitarianism is the view that they do. One major objection—the “monotonicity objection”—runs roughly as follows. For many particular causal relations, we can easily find a possible “blocker”—an additional causal factor that, had it also been there, would have prevented the cause from producing its effect. However—the objection goes on—, if the cause really necessitated its effect in the first place, it would have produced it anyway—despite the blocker. Thus, CN must be false. Though different (...) from Hume’s famous attacks against CN, the monotonicity objection is no less important. In one form or another, it has actually been invoked by various opponents to CN, past and present. And indeed, its intuitive appeal is quite powerful. Yet, this paper argues that, once carefully analysed, the objection can be resisted—and should be. First, I show how its success depends on three implicit assumptions concerning, respectively, the notion of cause, the composition of causal factors, and the relation of necessitation. Second, I present general motivations for rejecting at least one of those assumptions: appropriate variants of them threaten views that even opponents to CN would want to preserve—in particular, the popular thesis of grounding necessitarianism. Finally, I argue that the assumption we should reject is the one concerning how causes should be understood: causes, I suggest, include an element of completeness that excludes blockers. In particular, I propose a way of understanding causal completeness that avoids common difficulties. (shrink)

Wilson [Dialectica 63:525–554, 2009], Moore [Int Stud Philos Sci 26:359–380, 2012], and Massin [Br J Philos Sci 68:805–846, 2017] identify an overdetermination problem arising from the principle of composition in Newtonian physics. I argue that the principle of composition is a red herring: what’s really at issue are contrasting metaphysical views about how to interpret the science. One of these views—that real forces are to be tied to physical interactions like pushes and pulls—is a superior guide to real forces than (...) the alternative, which demands that real forces are tied to “realized” accelerations. Not only is the former view employed in the actual construction of Newtonian models, the latter is both unmotivated and inconsistent with the foundations and testing of the science. (shrink)

The present comment on Solari and Natiello’s paper values their constructivist approach to Newtonian Mechanics. My critical point concerns only the link between the concept of force and phenomena. It will be shown that the idealised form of the law of inertia created by the authors avoids criticism of the law and that this law leads to the concept of force as the cause of acceleration. This concept appears in the authors’ reconstruction as an assumption. They add that this assumption (...) must be contrasted with experiments. Following this, I address an experiment, in which the force that is taken as the cause of acceleration, is not present in the phenomenon at stake. As it thus does not satisfy the property of locality, which any cause has to, force cannot be a cause. (shrink)

We sometimes experience pleasures and displeasures simultaneously: whenever we eat sfogliatelle while having a headache, whenever we feel pain fading away, whenever we feel guilty pleasure while enjoying listening to Barbara Streisand, whenever we are savouring a particularly hot curry, whenever we enjoy physical endurance in sport, whenever we are touched upon receiving a hideous gift, whenever we are proud of withstanding acute pain, etc. These are examples of what we call " mixed feelings ". Mixed feelings are cases in (...) which one and the same person experiences pleasure and displeasure at the same time. Mixed feelings raise two questions: (1) If pleasure and displeasure are contraries, how can mixed feelings be possible? (2) Does the excess of pleasure (or displeasure) that we feel when experiencing mixed feelings itself constitute a new feeling, that results from the co-occurrence of the first two? I will argue (1) that mixed feelings are possible and that their existence does not threaten the contrariety of pleasure and displeasure, and (2) that there are no resultant feelings: having a lot of pleasure and a little displeasure does not result in having additional mild pleasure. Finally, I will suggest (3) that although both false, scepticism towards the existence of mixed feelings, as well as the idea according to which resultant feelings exist, are inspired from a single and correct idea: that pleasure and displeasure do fuse in some cases.

The argument from causal closure for physicalism requires the principle that a physical event can only occur through being necessitated by antecedent physical events. This article proposes a view of the causal structure of the world that claims not only that an event need not be necessitated by antecedent events, but that an event cannot be necessitated by antecedent events. All events are open to counteraction. In order to spell out various kinds of counteraction I introduce the idea of ‘directedness.’.

Although widely used across psychology, economics, and philosophy, the concept ofeffort is rarely ever defined. This article argues that the time is ripe to look for anexplicit general definition of effort, makes some proposals about how to arrive at thisdefinition, and suggests that a force-based approach is the most promising. Section 1presents an interdisciplinary overview of some chief research axes on effort, and arguesthat few, if any, general definitions have been proposed so far. Section 2 argues thatsuch a definition is (...) now needed and proposes a basic methodology to arrive at it, whosefirst step is to make explicit the various tacit assumptions about effort made acrosssciences and ordinary thinking. Section 3 unearths 4 different conceptions of effortfrom research on effort so far:primitive-feelings accounts,comparator-based accounts,resource-based accountsandforce-based accounts. It is then argued that the first 2kinds of accounts, although interesting in their own right, are not strictly speaking abouteffort. Section 4 considers the 2 most promising general approaches to efforts: re-source-based and force-based accounts. It argues that these accounts are not only compatible but actually extensionally equivalent. This notwithstanding, it explains why force-based accounts should be regarded as more fundamental than resource-basedaccounts -/- . (shrink)
