Abstract: Dispositions are modal properties. The standard conception of dispositions holds that each disposition is individuated by its stimulus condition(s) and its manifestation(s), and that their modality is best captured by some conditional construction that relates stimulus to manifestation as antecedent to consequent. In this paper Vetter proposes an alternative conception of dispositions: each disposition is individuated by its manifestation alone, and its modality is closest to that of possibility - a fragile vase, for instance, is one that can break easily. The view is expounded in some detail and defended against the major objections.Kleinsschmidt, Shieva.

Abstract: According to Principles of Sufficient Reason, every truth (in some relevant group) has an explanation. One of the most popular defenses of Principles of Sufficient Reason has been the presupposition of reason defense, which takes endorsement of the defended PSR to play a crucial role in our theory selection. According to recent presentations of this defense, our method of theory selection often depends on the assumption that, if a given proposition is true, then it has an explanation, and this will only be justified if we think this holds for all propositions in the relevant group. In this paper the author argues that this argument fails even when restricted to contingent propositions, and even if we grant that there is no non-arbitrary way to divide true propositions that have explanations from those that lack them. The author gives an alternate explanation of what justifies our selecting theories on the basis of explanatory features: the crucial role is not played by an endorsement of a PSR, but rather by our belief that, prima facie, we should prefer theories that exemplify explanatory power to greater degrees than their rivals.Comment: The text covers many topics in a level proper for undergraduates: The principle of sufficient reason, the inductive argument, the problem of the Many, explanatory power, etc. Even if the reader doesn't identify with the view of the author, this article could serve as a good practice to build confidence with philosophical concepts that are crucial for metaphysics and philosophy of science.

Summary: In this paper, Vetter looks at the argument for Dispositional Essentialism (DE) that has been put forward by A. Bird in his recent book Nature's Metaphysics. Bird's overall argument comes in two parts, one negative and one positive, which together are to establish DE as the best contender for a theory of properties and laws. Vetter argues that, even if all their particular steps go through, both parts of the argument have significant gaps. The negative argument, if successful, shows that at least one property has an essence, but not that any property has a dispositional essence. The positive argument, which aims to demonstrate the explanatory power of DE, fails to take account of the quantitative nature of the fundamental natural properties and laws. The paper finishes by suggesting a revision of DE's doctrine that might solve the latter problem, but yet remains to be spelled out.Comment: This paper explores in detail the metaphysics of dispositions. It is a good secondary reading for those who have already read Armstrong or Alexander Bird. Vetter writes in a very clear way, but a basic background in metaphysics might be needed to fully understand the paper. This reading is then more suitable for postgraduate courses in metaphysics or philosophy of science.

Abstract: The idea that dispositions are an intrinsic matter has been popular among contemporary philosophers of dispositions. This paper first states this idea as exactly as possible. Then it examines whether it poses any threat to the two current versions of the conditional analysis of dispositions, namely, the simple and reformed conditional analysis of dispositions. The upshot is that the intrinsic nature of dispositions, when properly understood, doesn't spell trouble for either of the two versions of the conditional analysis of dispositions. Along the way,the author proposes an extensionally correct and practically useful criterion for identifying nomically intrinsic dispositions and criticizes one objection raised by Lewis against the simple conditional analysis of dispositions.Comment: The article explains the different views about the connection between dispositions and counterfactual conditionals. It could be useful for senior undergraduates or for postgraduates interested in the metaphysics of conditional analyses.

Summary: This is a perfect overview article that serves as a general introduction to the topic of dispositions. It is composed of six sections that review the main philosophical approaches to the most important questions: Analysis of disposition ascription, the dispositional/categorical distinction, dispositions and categorical bases, the intrinsicness of dispositions and the causal efficacy of dispositions.Comment: A very good overview paper to introduce undergraduate students to the topic of dispositions.

Abstract: Why do some epistemic objects persist despite undergoing serious changes, while others go extinct in similar situations? Scientists have often been careless in deciding which epistemic objects to retain and which ones to eliminate; historians and philosophers of science have been on the whole much too unreflective in accepting the scientists' decisions in this regard. Through a re-examination of the history of oxygen and phlogiston, I will illustrate the benefits to be gained from challenging and disturbing the commonly accepted continuities and discontinuities in the lives of epistemic objects. I will also outline two key consequences of such re-thinking. First, a fresh view on the (dis)continuities in key epistemic objects is apt to lead to informative revisions in recognized periods and trends in the history of science. Second, recognizing sources of continuity leads to a sympathetic view on extinct objects, which in turn problematizes the common monistic tendency in science and philosophy; this epistemological reorientation allows room for more pluralism in scientific practice itself.Comment: An interesting argument about ontology and scientific practice; would be useful in any philosophy of science course that engages with issues in scientific practice.

Introduction: Things change: objects come into existence, last for a while, go out of existence, move through space, change their parts, change their qualities, change in their relations to things. All this would seem to be uncontroversial. But philosophical attention to any of these phenomena can generate perplexity and has resulted in a number of long-standing puzzles. One of the most famous puzzles about change threatens to demonstrate that nothing can persist through time, that all existence is momentary at best. Let's use the term 'alteration' for the sort of change that occurs when a persisting object changes its properties.Comment: A good overview of the philosophical issues involved in persistence through time. Would be a good preliminary material in a philosophy of time course. Or, since this is a fundamental philosophical problem, could be used in an introduction to philosophy course as a more clear alternative or supplement to ancient sources.

Abstract: It may appear that in order to be any way at all, a thing must exist. A possible - worlds version of this claim goes as follows: (E) For every x, for every possible world w, Fx at w only if x exists at w. Here and later in (R), the letter 'F' is used as a schematic letter to be replaced with a one - place predicate. There are two arguments against (E). The first is by analogy. Socrates is widely admired now but he does not exist now. So, it is not the case that for every x, for every time t, Fx at t only if x exists at t. Possible worlds are analogous to times. Therefore, (E) is false (cf., Kaplan 1973: 503 - 05 and Salmon 1981: 36 - 40). For the second argument, replace 'F' with 'does not exist'. (E) then says that for every x, for every possible world w, x does not exist at w only if x exists at w. This is obviously false. Therefore (E) is false (cf., Kaplan 1977: 498). Despite their considerable appeal, these arguments are not unassailable. The first argument suffers from the weakness inherent in any argument from analogy; the analogy it rests on may not.Comment: A very concise argument against the claim that existence is a prerequisite for having properties. This is a familiar claim, and this paper would be useful when it comes up to show that there is controversy about it. It does presuppose a basic understanding of possible world semantics, so should be reserved for courses where students already have a grasp of such semantics or the instructor wants to teach it beforehand.

Abstract: Sherlock Holmes is a fictional individual. So is his favorite pipe. Our pre-theoretical intuition says that neither of them is real. It says that neither of them really, or actually, exists. It also says that there is a sense in which they do exist, namely, a sense in which they exist "in the world of" the Sherlock Holmes stories. Our pre-theoretical intuition says in general of any fictional individual that it does not actually exist but exists "in the world of" the relevant fiction. I wish to defend this pre-theoretical intuition. To do so, I need to defend two claims: that fictional individuals do not actually exist, and that they exist "in the world of" the relevant fiction. The aim of this paper is to defend the first claim.Comment: A good argument against the existence of fictional characters. Clear presentation of the logic involved in various claims. In addition to ontology of art, the case of fictional characters can be an interesting way to present the arguments about ontology and linguistic commitment more generally, and this paper would be useful in that role as well.

Abstract: Deep theorizing about possibility requires theorizing about possible objects. One popular approach regards the notion of a possible object as intertwined with the notion of a possible world. There are two widely discussed types of theory concerning the nature of possible worlds: actualist representationism and possibilist realism. They support two opposing views about possible objects. Examination of the ways in which they do so reveals difficulties on both sides. There is another popular approach, which has been influenced by the philosophy of Alexius Meinong. The Meinongian approach is relevant to theorizing about possible objects because it attempts to construct a general theory of objects other than ordinary concrete existing objects. Independently of the debate about the nature of possible worlds or about Meinongianism, it is not always as straightforward as it may at first appear to determine whether putative possible objects are indeed possible. Another category of object similar to that of a possible object is the category of a fictional object. Although initially attractive, the idea that fictional objects are possible objects should not be accepted blindly. An important instance of theoretical usefulness of possible objects is their central role in the validation of two controversial theorems of a simple quantified modal logic.Comment: A good introduction to the different positions on possible objects, including their impact on modal logic. Would be a good starting point for a discussion of these issues in a metaphysics course, or as an introduction to these positions for an ontology of art/fiction course.

Vetter, Barbara. Dispositions without conditionals
2014, Mind 123(489): 129-156.
Comment: This article serves as a complementary reading for the book Potentiality: From Dispositions to Modality, or as a replacement for those who are only interested in Vetter's analysis of dispositions and not in her entire theory of potentialities. Recommendable for postgraduate courses in philosophy of language, metaphysics or philosophy of science.
