I don’t think Lynne Rudder Baker’s constitution view can account for personal identity problems of a synchronic or diachronic nature. As such, it cannot accommodate the Christian’s claim of eschatological bodily resurrection-a principle reason for which she gives this account. In light of this, I press objections against her constitution view in the following ways: First, I critique an analogy she draws between Aristotle’s “accidental sameness” and constitution. Second, I address three problems for Baker’s constitution view [‘Constitution Problems’ ], each (...) more problematic than the next: CP1: Her definition of constitution lacks explanatory power; CP2: If there is a plausible definition of constitution, constitution implies either too many persons or no human persons at all; CP3: Constitution yields no essential distinction between human and divine persons. If my argument go through, her constitution view has neither an explanation for diachronic personal identity nor personal identity through resurrection. (shrink)

Wild animals probably have net negative lives. Christine Korsgaard rejects the view that we might engineer paradise by redesigning nature and animals so that they have the best possible existences. She believes the genetic changes required would not be identity-preserving, thereby causing animals to cease to exist. I argue, first, that paradise engineering is permissible. Many harms are caused by non-sentient natural entities and processes. Moreover, sentient animals can survive modifications compatible with their psychological persistence over time. Second, we are (...) required to re-engineer nature in order to satisfy animals' right to the resources necessary for a reasonable life. (shrink)

Eric Olson criticizes Lynne Baker’s constitution account of persons on the grounds that personhood couldn’t be ontologically significant as nothing new comes into existence with the acquisition of thought. He claims that for something coming to function as a thinker is no more ontologically significant than something coming to function as a locomotor when a motor is added to it. He levels two related charges that there’s no principled answer about when and where constitution takes place rather than an already (...) existing object just acquiring new properties. I’ll argue that none of these objections are problems for understanding person to be a substantial kind. (shrink)

One of the central problems of personal identity is to determine what we are essentially . In response to this problem, Lynne Rudder Baker espouses a psychological criterion, that is, she claims that persons are essentially psychological. Baker’s theory purports to bypass the problems of other psychological theories such as Dissociative Identity Disorder and the problem of individuating persons synchronically. I argue that the theory’s treatment of Dissociative Identity Disorder leads to untenable results, is invalid, and consequently fails to individuate (...) persons. (shrink)

This paper aims to make headway on two related issues—one methodological, the other substantive. The former concerns cost–benefit analyses when applied to metaphysical theory choice. The latter concerns material coincidence, i.e., multiple objects occupying the same space at the same time, such as the statue and the clay from which it’s made. The issues are entwined as many reject coincidence on the grounds that it’s costly. I argue this judgment is unjustified. More generally, I set out and defend a framework (...) for the use of cost–benefit analyses in metaphysics. The framework employs a fourfold division of pretheoretical costs and benefits, and theoretical costs and benefits. Yet these do not hold equal weight. Instead I argue that the appeal to theoretical benefits is illegitimate if the theory in question cannot first account for the relevant evidence or data, including, crucially, certain bits of pretheoretical or common knowledge. This is crucial because I not only argue that material coincidence is consistent with common sense, against what is widely believed, but that coincidence may even be a feature or implication of the common sense view. Put together, the result is that accepting an anti-coincidence theory for its putative theoretical virtues at the expense of common sense is an improper usage of the cost–benefit methodology. I instead conclude that material coincidence should be accepted with equanimity—which, after all, is free. (shrink)

The central claim of this paper is that the Aristotelian metaphysics of objects is incompatible with physicalism. This includes the contemporary variant of Aristotelianism I call ‘sortalism’. The core reason is that an object’s identity as an instance of a (natural) kind, as well as its consequent persistence conditions, is neither physically fundamental nor determined by what is physically fundamental. The argument for the latter appeals to what is commonly known as ‘the grounding problem’; in particular I argue that the (...) physicalist has no solution, and this requires that the physicalist jettison the traditional concept of objects having kind-specific identity and persistence conditions.

The advent of the digital era brings with it the dream of ‘transcending the human’ through the most sophisticated AI / robot technologies. The Author argues that the concept and practices of ‘transcendence’ are deeply ambiguous, since on the one hand they simply aim to overcome the weaknesses, limits and fragility of the human, while on the other hand they modify the human by selecting its specific qualities and its causal properties in a way to generate beings ‘other than human.’ (...) As a matter of fact, post / trans-humanist ideologies, instead of strengthening the human, lead to its dehumanization because they imply the denial of the characteristics that are uniquely human and / or those that constitute human nature. To understand when new digital technologies enhance the human or distort it, it is necessary to analyze and evaluate social processes on the basis of a relational vision that shows us which human relationships emerge from the use of technologies.

I examine the debate between reductive and non-reductive physicalists, and conclude that if we are to be physicalists, then we should be reductive physicalists. I assess how both reductionists and non-reductionists try to solve the mind-body problem and the problem of mental causation. I focus on the problem of mental causation as it is supposed to be faced by non-reductionism: the so-called overdetermination problem. I argue that the traditional articulation of that problem is significantly flawed, and I show how to (...) articulate it properly: what I call the ‘super-overdetermination problem’. In doing so, I demonstrate that the problem of mental causation faced by non-reductionism is in fact a special case of the mind-body problem, as faced by non-reductionism, and that the former can’t be solved independently of the latter. I then assess the prospects for a particular family of non-reductive views that I call immanentism, and show that they fail to solve the super-overdetermination problem. Finally, I put forward two arguments to support the conclusion that physicalism entails reductionism. Both arguments establish, via distinct reasoning, the proposition that mental property instances are identical to physical property instances; and then each argument employs the inference, which I also defend, that if mental instances are physical instances, then mental properties are physical properties; hence, reductionism follows.
