This entry sketches the theory of personal identity that has come to be known as animalism. Animalism’s hallmark claim is that each of us is identical with a human animal. Moreover, animalists typically claim that we could not exist except as animals, and that the (biological) conditions of our persistence derive from our status as animals. Prominent advocates of this view include Michael Ayers, Eric Olson, Paul Snowdon, Peter van Inwagen, and David Wiggins.

The goal of this paper is to defend animalism from the remnant person problem. Specifically, I argue that animalism is consistent with the view that one could become a remnant person in virtue of psychological continuity. For this argument, I show that the dilemma for the remnant person parallels the dilemma animalists use when they argue that one could become a human vegetable or corpse. I then argue that animalists who claim that psychological continuity is not necessary for our persistence (...) through time should say that biological continuity is not necessary either. This implies that psychological continuity is sufficient, though not necessary, for personal identity over time in some cases. Finally, I show how my argument points animalists toward anti-criterialism and defend it from a fission problem. (shrink)

Our aim in this entry is to articulate the state of the art in the moral psychology of personal identity. We begin by discussing the major philosophical theories of personal identity, including their shortcomings. We then turn to recent psychological work on personal identity and the self, investigations that often illuminate our person-related normative concerns. We conclude by discussing the implications of this psychological work for some contemporary philosophical theories and suggesting fruitful areas for future work on personal identity.

Constitution theorists have argued that due to a difference in persistence conditions, persons are not identical with the animals or the bodies that constitute them. A popular line of objection to the view that persons are not identical with the animals/bodies that constitute them is that the view commits one to undesirable overpopulation, with too many minds and too many thinkers. Constitution theorists are well aware of these overpopulation concerns and have gone a long way toward answering them. However, there (...) is one mental excess worry that remains especially problematic. It is argued here that the worry about too many thoughts, or too many instantiations of mentality in general, remains a serious threat to the constitution view of persons. What exactly the threat is and how it arises is described in detail in Section III. It is then shown that attempts to allay the concern are unsuccessful. I argue, in particular, that appealing to the distinction between derivative and non-derivative instantiation fails to solve the problem. (shrink)

Among your closest associates is a certain human animal – a living, breathing, organism. You see it when you look in the mirror. When it is sick, you don't feel too well. Where it goes, you go. And, one thinks, where you go, it must follow. Indeed, you can make it move through sheer force of will. You bear, in short, an important and intimate relation to this, your animal. So too rest of us with our animals. Animalism says that (...) this relation is nothing short of identity. According to animalists, we do not only coincide with or constitute or inhabit or otherwise hang out with these close associates, our animals: we are them. In this article, I offer an opinionated take on what animalism might be and situate it against contemporary rivals. Then, I outline a simple case for animalism. Finally, I sketch non-standard routes for animalists to take in light of standard challenges. My goal in all of this is to open up some new avenues of animalist thinking. (shrink)

How should we count people who have two cerebral hemispheres that cooperate to support one mental life at the level required for personhood even though each hemisphere can be disconnected from the other and support its "own" divergent mental life at that level? On the standard method of counting people, there is only one person sitting in your chair and thinking your thoughts even if you have two cerebral hemispheres of this kind. Is this method accurate? In this paper, I (...) argue that it is not, and I advocate an alternative I call the Multiple Person View. (shrink)

The central argument for animalism is the thinking animal problem : if you are not an animal, there are two thinkers within the region you occupy, i.e., you and your animal body. This is absurd. So you are an animal. The main objection to this argument is the thinking brain problem : animalism faces a problem that is structurally analogous to TAP. Specifically, if animalism is true, you and your brain both think. This is absurd. So animalism is false. The (...) purpose of this paper is to propose strategies animalists can endorse to solve TBP. I first show that animalists can solve TBP by arguing that it is not sound. This solution to TBP raises questions about personal identity over time and the mereological relation between the person and the brain. I argue that animalists can answer the personal identity question by endorsing non-biological persistence conditions as well as biological ones. For the mereological question, I first show that animalism is incompatible with four-dimensionalism and eliminativism. I then argue that animalists should endorse the dominant sortal account to answer the mereological question. (shrink)

The central objection to the constitution view is the too many thinkers problem - if the animal that constitutes you thinks and you are not it, then there are two thinkers within the region you occupy. Lynne Rudder Baker claims that the animal thinks only derivatively, in virtue of constituting the person that thinks nonderivatively, and this leads to a solution to the too many thinkers problem. This paper offers two objections to Baker’s solution. First, the idea of derivative/ nonderivative (...) properties faces a dilemma unacceptable to constitutionalists: either the too many thinkers problem is reinstated or the constitution view is undermined by the idea itself. Further, Baker should concede that the person thinks in virtue of brain functions. This implies, contra Baker’s claim, that the person thinks derivatively and the animal thinks nonderivatively. The paper also considers a way in which Baker might respond to the two objections. (shrink)

When does a human being cease to exist? For millennia, the answer to this question had remained largely unchanged: death had been diagnosed when heartbeat and breathing were permanently absent. Only comparatively recently, in the 1950s, rapid developments in intensive-care medicine called into question this widely accepted criterion. What had previously been deemed a permanent cessation of vital functions suddenly became reversible. -/- A new criterion of death was needed. It was suggested that the destruction of the brain could indicate (...) the death of the organism in the presence of external life support. Soon the so-called brain death became the new worldwide standard. In recent years, however, doubts about this neurological criterion have been growing. Is brain death really our death? -/- This is the question that this thesis seeks to answer. To this end, we shall connect the medical debate about the definition of death to the philosophical debate about personal identity. While we will find that the destruction of its brain does in fact not correspond to an organism’s death, we shall also ask whether the assumption that we are essentially organisms is correct. May brain death be the ceasing to exist of a different entity? -/- Substituting clinical case reports and considerations about human physiology for the use of thought experiments, the thesis takes a novel and philosophically unconventional approach to the problem of what we essentially are. We shall analyse various pathological conditions and their respective effects on the bodily and mental characteristics of our existence. We will conclude that brain death is indeed our death – but for reasons entirely different from those cited in the original justification of this criterion. (shrink)

The central objection to neo-Lockeanism about persons is the too many thinkers problem: NLP ends up with an absurd multiplication of thinkers. Sydney Shoemaker attempts to solve this problem by arguing that the person and the animal do not share all of the same physical properties. This, according to him, leads to the idea that mental properties are realized in the person’s physical properties only. The project of this paper is to reject Shoemaker’s physicalist solution to the too many thinkers (...) problem. I first argue that his physicalism fails to explain why two physically indistinguishable objects differ in their persistence conditions and physical properties. I then argue that Shoemaker illicitly treats the case of the person and the case of the animal differently, first in regard to cerebral function and its relation to mental properties, and second in regard to brainstem function and its relation to biological properties. This shows that Shoemaker’s solution actually undermines his entire argument. (shrink)

According to a prominent view of organism persistence, organisms cease to exist at death. According to a rival view, organisms can continue to exist as dead organisms. Most of the arguments in favor of the latter view rely on linguistic and common sense intuitions. I propose a new argument for somaticism by appealing to two other sources that have thus far not figured in the debate: the concept of naturalness, and biological descriptions of organisms, in particular in ethology and ecology. (...) I show that if we hone in on the relevant notion of naturalness, we can show that organisms can continue to instantiate the natural property being an organism after death. (shrink)

Physicalist Christology is the view that God the Son, in the Incarnation, became identical with the body of Jesus. The goal of this paper is to defend PC from two recent objections. One is that if GS is a physical object, then he cannot have properties had by God. Then, by Leibniz’s law, the incarnate GS cannot be identical with the second Person of the Trinity. The other objection is that PC implies that the incarnate GS did not exist in (...) the interim period between his death and resurrection. PC then leads to the theologically absurd consequence that one of the three Persons of the Trinity did not exist during this period. I argue that the first objection fails because the very same argumentative strategy applies to the Incarnation on any view. As for the second objection, I endorse an animalist theory of death and argue that the incarnate GS continues to exist as a dead person from his death to resurrection. This shows that there is still continuing Trinity of GS during this period. (shrink)

Among the questions to be raised under the heading of “personal identity” are these: “What are we?” (fundamental nature question) and “Under what conditions do we persist through time?” (persistence question). Against the dominant neo-Lockean approach to these questions, the view known as animalism answers that each of us is an organism of the species Homo sapiens and that the conditions of our persistence are those of animals. Beyond describing the content and historical background of animalism and its rivals, this (...) entry explores some of the arguments for and objections to this controversial account of our nature and persistence.
