The Dead Donor Rule holds that removing organs from a living human being without their consent is wrongful killing. The rule still prevails in most countries, and I assume it without argument in order to pose the question: is it possible to have a metaphysically correct, clinically relevant analysis of human death that makes organ donation possible? I argue that the two dominant criteria of death, brain death and circulatory death, are both empirically and metaphysically inadequate as definitions of human death, and therefore of no epistemic value in themselves. I first set out a neo-Aristotelian theory of death as separation of soul (understood as organising principle) and body, which is then fleshed out as loss of organismic integrity. The brain and circulatory criteria are shown to have severe weaknesses as physiological manifestations of loss of integrity. Given the mismatch between what death is metaphysically speaking, and the dominant criteria accepted by clinicians and philosophers, it turns out that only actual bodily decomposition is a sure sign of death. In this I differ from Alan Shewmon, whose important work I discuss in detail.

Tyron Goldschmidt has recently published a non-paper in which he claims to demonstrate the causal power of absences. His non-paper is, precisely, an empty page. The non-paper is ingenious and at first ‘glance’ the ‘reader’ might think that the absence of words on the page does prove that negative beings can literally cause states such as surprise or disappointment. Closer analysis, however, shows that Goldschmidt’s clever non-paper not only lacks words but also lacks causal power. Serious metaphysical problems pile up if we suppose otherwise.

_Real Essentialism_ presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like – can we define and classify reality? Many, if not most, philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. _Real Essentialism_ reinvigorates the tradition of realist, essentialist metaphysics, defending the reality and knowability of essence, the possibility of objective, immutable definition, and its relevance to contemporary scientific and metaphysical issues such as whether essence transcends physics and chemistry, the essence of life, the nature of biological species, and the nature of the person.

Corruptionism is the view that following physical death, the human being ceases to exist but their soul persists in the afterlife. Survivalism holds that both the human being and their soul persist in the afterlife, as distinct entities, with the soul constituting the human. Each position has its defenders, most of whom appeal both to metaphysical considerations and to the authority of St Thomas Aquinas. Corruptionists claim that survivalism violates a basic principle of any plausible mereology, while survivalists tend to reject the principle, though without as much detail as one would like. In this paper I examine both the key exegetical issues and the mereological question, arguing that Aquinas cannot be shown to have supported the principle in question, and that the principle should be rejected on independent grounds. If correct, some key planks in support of survivalism are established, with others to await further examination.

Antonio Ramos Díaz has recently given an extensive critique of what I have called the “storage problem” for materialism about the human mind. I respond to Díaz, showing that his critique fails. First, I rehearse the storage problem, explaining what claims it does and does not involve. I then consider Díaz’s “strong” and “weak” interpretations of my argument, explaining why I do not subscribe to the strong version, which misinterprets my position, especially concerning the meaning of the term “concrete.” His weak version of my argument is closer to what I intend, but Díaz’s own unpacking of this interpretation also commits me to claims I do not, for very good reasons, accept. Díaz does not, in the end, show the storage problem to be—as he thinks—an unsound way of arguing for dualism. Getting concepts into a purely material human intellect still looks like the metaphysical equivalent of fitting a square peg into a round hole.

Contemporary liberal societies are seeing increasing pressure on individuals to act against their consciences. Most of the pressure is directed at freedom of religion but it also affects ethical beliefs more generally, contrary to the recognition of freedom of religion and conscience as a basic human right. I propose that freedom of dissociation, as a corollary of freedom of association, could be a practical and ethically acceptable solution to the conscience problem. I examine freedom of association and explain how freedom of dissociation follows from it, showing how dissociation protects freedom of religion and conscience. Extreme cases, such as the problem of the Satanist nurse, can be handled within a dissociationist framework, so it is reasonable to think less extreme cases can also be dealt with. The serious objection that dissociationism entails unjust discrimination is answered primarily by appeal to the need for ‘full and fair access’ to goods and services by all groups. I then allay important concerns about what kind of liberal society we should want to live in. Next, I refute the charge that a dissociationist society violates liberalism's ‘higher good’, arguing that liberalism strictly does not have a higher good. I conclude with some reflections on what a dissociationist society might look like.

I build a case for the impossibility of natural necessity as anything other than a species of metaphysical necessity – the necessity obtaining in virtue of the essences of natural objects. Aristotelian necessitarianism about the laws of nature is clarified and defended. I contrast it with E.J. Lowe’s contingentism about the laws. I examine Lowe’s solution to the circularity/triviality problem besetting natural necessity understood as relative necessity. Lowe’s way out is subject to serious problems unless it is given an essentialist turn, which he declines to do. Further, his defence of contingency in terms of possible variation in the natural constants is found wanting, as is a related defence given by Kit Fine. I examine and raise problems for a recent, Lowe-inspired defence of a hybrid view of the modal status of laws given by Tuomas Tahko. Aristotelian necessitarianism, by contrast, can account for the sorts of phenomena to which contingentists typically appeal.

There are a number of ways in which a person can share the guilt of another's wrongdoing. He might advise it, command it or consent to it. He might provoke it, praise it, flatter the wrongdoer, or conceal the wrong. He might stay silent when there is a clear duty to denounce the wrong or its perpetrator; or he might positively defend the wrong done. Finally, he might actively participate or cooperate in the wrongdoing. These various activities, apart from cooperation, typically occur before or after the commission of the wrong itself, only provocation being essentially before the fact. As such they fall into the categories of seduction or comfort, seduction being essentially pre-commission and comfort post-commission. In seduction, the seducer typically leads another into doing wrong who has not definitely made up his mind. He does not assist in the commission, but he leads to its occurring. If the principal has made up his mind, actions which might otherwise amount to seduction are best characterized as amounting to scandal, since they do not lead to wrong but reinforce the principal in his wrongful intent or provide to third parties a bad example since they connote approval of the principal's action. Closely related to the concept of seduction is that of solicitation, though perhaps these are best thought of as two aspects of the same kind of activity. Seduction can be thought of as a strong form of inducement to wrong, typified by command, counsel and enticement through praise or provocation. Solicitation is a softer form of inducement typically involving requests, appeals, and invitations. Whereas the seducer or solicitor leads another into wrong but does not assist in its commission, the co-operator does not lead the principal into wrong but assists in its commission.

Things change. If anything counts as a datum of metaphysics, that does. Change occurs in many ways: it can be accidental or substantial; essential or non-essential; intrinsic or extrinsic; subjective or objective. Changes can be physical, spatial, quantitative, qualitative, natural, artefactual, conceptual, linguistic. Events are arguably best defined as changes in an object or objects. All change is from something and into something, and hence is at least a two-term relation, involving a term from which and a term to which.

There is a tension between the reasonable desire not to be judgmental of other people’s behaviour or character, and the moral necessity of making negative judgments in some cases. I sketch a way in which we might accommodate both, via an evaluation of the good of reputation and the ethics of judgment of other people’s character and behaviour. I argue that a good reputation is a highly valuable good for its bearer, akin to a property right, and not to be damaged without serious reason deriving from the demands of justice and the common welfare. Rash judgment wrongfully damages reputation and is sometimes a seriously immoral act. Rashness is not merely about lack of evidence, but involves lack of charity and is to be avoided even in some cases where the evidence of bad character or action is epistemically sufficient for judgment. I argue that the desirability of a good name for its holder, whether the reputation is deserved or not, means that in all but a relatively narrow range of cases it is always wrong to think badly of someone, even if they are bad.

I have not been able to locate any critique of Hume on substance by a Schoolman, at least in English, dating from Hume's period or shortly thereafter. I have, therefore, constructed my own critique as an exercise in ‘post facto history’. This is what a late eighteenth-century/early nineteenth-century Scholastic could, would, and should have said in response to Hume's attack on substance should they have been minded to do so. That no one did is somewhat mysterious. My critique is precisely in the language of the period, using solely the conceptual resources available to a Schoolman at that time. The arguments, however, are as sound now as they were then, and in this sense the paper performs a dual role—contributing to the defence of substance contra Hume, and filling, albeit two hundred years or so too late, a gap in the historical record

Central to recent debate over the Kalam Cosmological Argument, and over the origin of the universe in general, has been the issue of whether the universe began to exist and, if so, how this is to be understood. Adolf Grünbaum has used two cosmological models as a basis for arguing that the universe did not begin to exist according to either of them. Concentrating in this paper on the second (“open interval”) model, I argue that he is wrong on both counts. I give metaphysical considerations for rejecting Grünbaum’s interpretation of the second model and offer a definition of the beginning of existence of an object that improves on prior formulations and that is adequate to show how the universe can indeed be seen to have begun to exist. I conclude with a more general metaphysical discussion of the beginning of the universe and of the Kalam Cosmological Argument.
