Balog, Katalin. Conceivability, possibility, and the mind-body problem
1999, Philosophical Review 108 (4):497-528.

Expand entry

Added by: Clotilde Torregrossa, Contributed by: Simon Fokt

Abstract: In (Chalmers, 1996), David Chalmers influentially argued that if physicalism is true then every positive truth is a priori entailed by the full physical description—this is called 'the a priori entailment thesis'. However, ascriptions of phenomenal consciousness are not so entailed and thus he concludes that Physicalism is false. As he puts it, 'zombies' are metaphysically possible. I attempt to show that this argument is refuted by considering an analogous argument in the mouth of a zombie. The conclusion of this argument is false so one of the premises is false. I argue at length that this shows that the original conceivability argument also has a false premise and so is invalid.

Comment: This paper is most suitable for further reading in any course which discusses consciousness and conceivability arguments. Note that this paper was chosen by The Philosopher's Annual as one of the ten best articles appearing in print in 2000 and so is reprinted in Volume XXIII of The Philosopher's Annual.

Abstract: The Explanatory Gap' is a label for the idea that we cannot explain consciousness in terms of brain activity. There are many different formulations of the explanatory gap, but all discussion about it assumes that there is only one gap, which consists of the absence of a deductive explanation. This assumption is mistaken. In this paper, I show that the position that deductive explanation is privileged in this case is unmotivated. I argue that whether or not there is an explanatory gap depends on the kind of explanation in question, so there is no single, unified explanatory gap but only the absence and (perhaps) presence of different sorts of explanation.

Harman, Elizabeth. The potentiality problem
2003, Philosophical Studies 114 (1-2):173 - 198.

Abstract: Many people face a problem about potentiality: their moral beliefs appear to dictate inconsistent views about the signifcance of the potentiality to become a healthy adult. Briefy, the problem arises as follows. Consider the following two claims. First, both human babies and cats have moral status, but harms to babies matter more, morally, than similar harms to cats. Second, early human embryos lack moral status. It appears that the first claim can only be true if human babies have more moral status than cats. Among the properties that determine moral status, human babies have no properties other than their potentiality that could explain their having more moral status than cats. So human babies' potentiality to become adult persons must explain their having more moral status than cats. But then potentiality must raise moral status generally. So early human embryos must have some moral status. It appears that the view that must underlie the first claim implies that the second claim is false.

Harman, Elizabeth. Can we harm and benefit in creating?
2004,

Expand entry

Added by: Clotilde Torregrossa, Contributed by: Simon Fokt

Abstract: The non-identity problem concerns actions that affect who exists in the future. If such an action is performed, certain people will exist in the future who would not otherwise have existed: they are not identical to any of the people who would have existed if the action had not been performed. Some of these actions seem to be wrong, and they seem to be wrong in virtue of harming the very future individuals whose existence is dependent on their having been performed. The problem arises when it is argued that the actions do not harm these people - because the actions do not make them worse off than they would otherwise be.1 Consider: Radioactive Waste Policy: We are trying to decide whether to adopt a permissive radioactive waste policy. This policy would be less inconvenient to us than our existing practices. If we enact the newly-proposed policy, then we will cause there to be radioactive pollution that will cause illness and suffering. However, the policy will have such significant effects on public policy and industry functioning, that different people will exist in the future depending on whether we enact the policy. Two things should be emphasized. First, the illness and suffering caused will be very serious: deformed babies, children with burns from acid rain, and adults dying young from cancer. Second, the policy will affect who will exist in the future because our present practices invade people's everyday lives, for example by affecting recycling practices in the home; these practices will change if the policy is adopted. Furthermore, whether we adopt the policy will determine which plants are built where, what jobs are available, and what trucks are on the road. These effects will create small differences in everyone's lives which ultimately affect who meets whom and who conceives with whom, or at least when people conceive. This affects who exists in the future.

Chatti, Saloua. Avicenna on Possibility and Necessity
2014, History and Philosophy of Logic 35(4): 332-353.

Expand entry

Added by: Sara Peppe

Abstract: In this paper, I raise the following problem: How does Avicenna define modalities? What oppositional relations are there between modal propositions, whether quantified or not? After giving Avicenna's definitions of possibility, necessity and impossibility, I analyze the modal oppositions as they are stated by him. This leads to the following results: 1. The relations between the singular modal propositions may be represented by means of a hexagon. Those between the quantified propositions may be represented by means of two hexagons that one could relate to each other. 2. This is so because the exact negation of the bilateral possible, i.e. 'necessary or impossible' is given and applied to the quantified possible propositions. 3. Avicenna distinguishes between the scopes of modality which can be either external (de dicto) or internal (de re). His formulations are external unlike al-F̄ar̄ab̄;’s ones. However his treatment of modal oppositions remains incomplete because not all the relations between the modal propositions are stated explicitly. A complete analysis is provided in this paper that fills the gaps of the theory and represents the relations by means of a complex figure containing 12 vertices and several squares and hexagons.

Comment: This article is useful for eastern philosophy courses and logic courses. Although the first part provides an accessible introduction to Avicenna's perspective, it would be better for students to have some prior background in logic. This article is useful for eastern philosophy courses and logic courses. Even if in the first part it provides an introductory section on Avicenna's perspective, it would be better to have some pre-esxisting background on this latter one.

Cartwright, Nancy. Causal Laws and Effective Strategies
1979, Nous 13(4): 419-437.

Added by: Emily Paul, Contributed by: Daniel Kokotajlo

Summary: Argues for the irreducibility of causal laws to laws of association, probabilistic or deterministic. Statistical or probabilistic analyses of causality, which typically require that the cause increase or alter the probability of the effect, cannot succeed because causes increase the probability of their effects only in situations that exhibit causal homogeneity with respect to that effect (Simpson's paradox). This condition must enter the definition of an effective strategy, which is why causal laws are ineliminable for scientifically grounded interventions in nature.

Comment: I would recommend this as a further reading for a unit on causation and the laws of nature. It would be especially useful if situated within a metaphysics course where students have already come across general reductive accounts - e.g. reductive accounts of modality.

Sullivan, Meghan. Are There Essential Properties? No.
2016, in Elizabeth Barnes (ed.) Current Controversies in Metaphysics, Routledge: 45-61.

Expand entry

Added by: Emily Paul

Abstract: This paper describes motivations for the view that some objects have essential properties: properties which they must have in any world/situation where they exist (without qualification). I raise objections to the motivations for so-called ``hardcore essentialism''. And I articulate and defend an alternative theory: explanation-relative essentialism.

Comment: Very useful for an intermediate Metaphysics course. Could be good to include this reading after teaching about modality, as a way to apply possible worlds talk to a new topic: are there certain properties that objects/entities must have in every possible world, in order to be that very object/entity? It could also be useful to teach de re/de dicto necessity first.

Introduction: It is not easy to say what metaphysics is. Ancient and Medieval philosophers might have said that metaphysics was, like chemistry or astrology, to be defined by its subject matter: metaphysics was the 'science' that studied 'being as such' or 'the first causes of things' or 'things that do not change'. It is no longer possible to define metaphysics that way. First, a philosopher who denied the existence of those things that had once been seen as constituting the subject-matter of metaphysics - first causes or unchanging things - would now be considered to be making thereby a metaphysical assertion. Second, there are many philosophical problems that are now considered to be metaphysical problems (or at least partly metaphysical problems) that are in no way related to first causes or unchanging things - the problem of free will, for example, or the problem of the mental and the physical. The first three sections of this entry examine a broad selection of problems considered to be metaphysical and discuss ways in which the purview of metaphysics has expanded over time. The central problems of metaphysics were significantly more unified in the Ancient and Medieval eras. Which raises a question - is there any common feature that unites the problems of contemporary metaphysics? The final two sections of the entry discuss some recent theories of the nature and methodology of metaphysics, including those that consider metaphysics as an impossible enterprise.

Comment: Essential article for introducing metaphysics to undergraduete students.The article offers a clear overview of the main problems of metaphysics as well as of the historical evolution from antient to contemporary metaphysics.
