The Illusion of Survival

TheIllusion of Survival (small)When people ask what the Phantom Self is about and I have to come up with an elevator speech of a minute or less, I’ve started saying something along the lines of, “There is no fundamental difference between your relationship to your future self and your relationships to other people.” This sometimes strikes a chord, making people want to hear more. It’s better than leading with teleportation, although teleportation is not bad at parties, where people take it as an invitation to play; they light up and start recalling the Hollywood fantasies they enjoyed in their misspent youth, the more outrageous the better. It’s way better than starting off with the idea that we are informational entities, to which people respond as though they’d stepped in something squishy.

There’s no doubt that this material is hard to understand, still harder to explain. It doesn’t help that it’s spread over 60-odd posts written over three and a half years. I can’t distill it all into a one-minute elevator speech. But if I had to pick one key finding—the most important—it would be that personal survival is an illusion. And although support for this claim—which is puzzling and incomprehensible if you come across it cold—is scattered throughout 400 pages or so, no single post addresses this point directly.

So here goes. Continue reading “The Illusion of Survival”

Religion as an Antidote to the Self

“Why does religion exist?” is a challenging question for both the natural and the social sciences. There is a fact to be explained: a large majority (about 85%) of human beings profess religious beliefs and engage in religious practices. For evolutionary biology, the challenge is to explain why religion caught on so well. Did religions confer a competitive advantage on the members of our species who adopted them? If they once did, do they still confer a competitive advantage? Although a ‘gene for religion’ is unlikely, religious affiliation is heritable: the strongest determinant of an individual’s religion is the religion of his parents. [Dennett, 2006, p 86] Religious observance is costly, requiring the erection of places of worship and maintenance of a priesthood, and could be presumed on that account to reduce the evolutionary fitness of believers as compared to their more worldly competitors. Why, then, have religions flourished? Almost the same question confronts economic theory, which assumes human behaviour is best modelled by Homo economicus, an agent who always chooses what he believes is in his own interests. Why would such agents choose religion, which requires personal sacrifice with no clear payback, or at least without the kind of payback that motivates the same agents in their other transactions such as work for pay and pay for groceries. A parallel question faces psychology. Religions commonly advocate self-denial, which can be presumed to be psychologically repellent. Why are people attracted by institutions and practices which ask them to give up pleasures?

All the world’s major religions try to curb human selfishness. They attempt to break their followers’ obsession with their personal lives, and encourage them to care about something larger than themselves. An aim of religion is to alter human motivation: to guide thought and motivate action in directions that run counter to ‘natural’ inclinations.

I want to examine the hypothesis that religion arose as a response to the emergence of the self as a motivational centre in human psychology. Continue reading “Religion as an Antidote to the Self”

Anatta to Agape – Mark Johnston’s Surviving Death

In a remarkable book, Surviving Death, Mark Johnston reaches several surprising conclusions about persons and personal identity. One of them, as the title implies, is that persons can survive their biological deaths. This claim does not depend on the existence of anything resembling an immaterial, substantial soul; Johnston’s account of post-death survival is entirely naturalistic.

Johnston has packed a lot into five long chapters, originally presented as a Carl G. Hempel lecture series at Princeton. I am impressed by the stamina of the audience, who attended to what must have been a full week of close and often counterintuitive argument and stayed to ask penetrating questions. I doubt I could have followed it all—and so, am grateful to have the lectures in printed (actually e-book) form, for they are rich with insight.

Having read Johnston’s 1997 attack on Parfit’s neo-Lockeanism, “Human Concerns Without Superlative Selves,” I had pegged him as a ‘conservative’ about personal identity. But Surviving Death reveals a theory of personhood as radical as any. Continue reading “Anatta to Agape – Mark Johnston’s Surviving Death”

Parfit’s Retreat: “We Are Not Human Beings”

In a new paper, “We Are Not Human Beings,” Derek Parfit argues that persons are identically their conscious, thinking parts, which he identifies as their cerebrums.  This is a significant departure from the position he defended in Reasons and Persons, that personal identity consists in non-branching psychological continuity and connectedness with any cause:

Our identity over time just involves (a) Relation R—psychological connectedness and/or psychological continuity, either with the normal cause or with any cause, provided (b) that there is no different person who is R-related to us as we once were. [Parfit, 1984, p 216]

I call Parfit’s new view a “retreat” because it is a move away from the radical insights about what we are which illuminated Reasons and Persons, to a ‘conservative’ account of persons as physical substances. I find the move puzzling, because I can’t see that Parfit is compelled to make it, and disappointing, because it raises once again the fog of mysteries about persons that looked well on their way to being dispelled.

Parfit’s claim that persons are their cerebrums has as a direct consequence that persons cannot survive information-based teleportation. If  I plan to be teleported to Mars, I should accept that my replica on Mars will not be me, because my replica’s cerebrum is numerically different from my cerebrum. The cerebrum is a body part, which, like any other ordinary material object, ceases to exist when it is destroyed. Its replica on Mars is a different cerebrum—hence, if Parfit is right, a different person.

Parfit has long thought that survival—a person’s continued existence—is different from what matters in survival. His new view on what persons are could perhaps coexist with his earlier position that information-based teleportation preserves everything that matters in survival. But such coexistence, I will argue, is an uneasy truce between fundamentally warring ideas. An alternative account of what persons are—informational entities—is a better fit to Parfit’s intuition (which I endorse) that nothing important need be lost in teleportation of persons.

“Why We Are Not Human Beings” is Parfit’s response to animalism—the view put forward by Eric Olson and others that persons are identical to animals, or biological organisms. (In the animalist literature, “human being” is used as a synonym for “human animal.”) In this review of Parfit’s paper, I raise the following points:

  1. The arguments Parfit brings to bear against animalism rely on an intuition that has equal force against the paper’s conclusion that persons are their cerebrums.
  2. The claim that persons are their brains was strongly rejected in Reasons and Persons for reasons that supported a central argument of that book. If we were identical to our cerebrums, Parfit’s main argument against the Self-Interest Theory would be undercut in the same way that it would be if we were identical to our (whole) brains.
  3. The claim that we are our cerebrums weakens Parfit’s argument in Reasons and Persons that “ordinary survival is about as bad as being destroyed and having a Replica.” If I am my cerebrum, it is hard to believe that destruction of my cerebrum is not especially bad for me, even if a replica of my cerebrum is manufactured in its stead.

What Does Matter

Derek Parfit’s Reasons and Persons began, “Many of us want to know what we have most reason to do.” He aimed to establish a foundation for ethics, a project which required addressing the conflicts between morality and self-interest. In asking what the claims of self-interest really are, Parfit came to grips with the question of whether or not there is a rational basis for the special concern that persons feel for themselves. Although Reasons and Persons did not answer that question, Parfit tried to show that the Self-Interest Theory—which claims that each person has the “supremely rational ultimate aim: that his life go, for him, as well as possible”—is false.

Parfit went on to write On What Matters, following an honoured tradition of searching for a kind of Unified Field Theory of ethics—one law, from the correct application of which all moral precepts can be derived. Reasons and Persons famously argued that personal identity is not what matters in survival; and it is surely not coincidental that the phrase “what matters” recurred in the title of Parfit’s new book.  Normative ethics consists of giving reasons for action; and reasons for action matter. Because the survival of persons is very important, what matters in survival can be presumed to be a significant part of what matters.

On What Matters says little about personal identity. Parfit’s primary interest is in discovering reasons for action—a rational basis for decision-making. My primary interest is in gaining a better understanding of human nature—of what we are. Parfit’s work is driven by prescriptive aims, mine by descriptive ones. Parfit and I would probably agree that reasons for action are rooted in values. But where he asks what has value, I ask what people actually value, and—a more interesting question—why they value what they do. Continue reading “What Does Matter”

Anticipation and the Extreme Claim

The Apparent Rationality of Prudential Concern

Consider the following apparently straightforward inference:

I do not expect to die soon. Therefore I expect to be alive in the future. I expect I will have experiences in the future. I anticipate having experiences in the future. Because experiences can be pleasant or unpleasant, I have reason to care about the quality of those experiences.

Notice the flow of argument: from a straightforward prediction of fact—that my death is not imminent—and the seemingly innocuous observations that persons persist through time, that persons have experiences, and that experiences vary in quality, to the conclusion that I have a reason to care about the quality of my future experiences. The steps in the argument seem innocent and deeply familiar. These ideas are so closely linked as to seem inseparable.

I suggest they seem inseparable because the core concept of a person is that of a subject of experience that persists through time. Because experiences can be pleasant or unpleasant, we think a subject has reason to care about their quality in the future.

By “subject of experience” I just mean whatever has experiences. I am not claiming that the concept of a person is that of a Cartesian ego, or a spiritual substance, or a biological organism, or its brain, or any sort of psychological entity. I claim only that the concept of a person is of something that has experiences. This claim is uncontroversial.

The above argument illustrates how a motivational idea—having a reason to care about something—can be embedded in what appears to be a straightforward factual description. Continue reading “Anticipation and the Extreme Claim”

Towards a Scientific Theory of Persons

Paradigm Shift

I do not expect a theory of personhood to match all our pre-reflective philosophical intuitions, even if deeply considered and strongly felt (especially if strongly felt!) for two reasons: (1) our best intuitions on this subject are demonstrably unreliable, and (2) billions of otherwise sane and competent people hold beliefs about personal identity which are unsupported by empirical evidence, but to which they have strong emotional attachment. These two facts strongly suggest that there is something wrong with what we are naively inclined to believe about our identity. Hence we should not be surprised to find that a satisfactory solution, when it is found, will at first seem counter-intuitive. Continue reading “Towards a Scientific Theory of Persons”

Open Individualism – Being Everyone

The term “Open Individualism” has a positive ring. If Daniel Kolak hadn’t adopted it, I might have used the word “open” for my own theory of what persons are. I haven’t yet hit upon a term ending in “ism” to represent the idea that persons are informational entities, or (to say the same thing differently) bundles of attributes, as opposed to substances. Like rivers whose constitutive substance (water) is always changing, persons constantly gain and lose attributes. And attributes are easily shared, readily copied from one individual to another. When you learn something from another person, you absorb part of himself. He is a collection of attributes, just as a book (the intellectual work, not the bound volume made of paper) is a sequence of sentences. To learn from another person is like incorporating a quotation from someone else’s book into one’s own composition. In learning from him, we take on part of what he is. The fact that attributes (or information, if you prefer) flow so freely between persons, makes the word “open” appropriate. We are open vessels, not closed ones. Continue reading “Open Individualism – Being Everyone”

Kolak: I Am You

People who think deeply about the puzzle cases of personal identity have come up with a variety of bold and radical responses. Like Alexander hacking through the Gordian knot, Parfit wielded an analytical scalpel to divide personal identity from what matters in personal survival, reaching the conclusion that ordinary survival is about as bad as being destroyed and replaced by a replica. Robert Nozick was so impressed by the difficulties posed by fission cases that he decided personal identity must depend on extrinsic factors: you are identical to whatever person is your closest continuer at any future time, a thesis with the odd consequence that, if your closest continuer after fission dies, you may suddenly find yourself being someone who until that time was someone else, your second-closest continuer. David Lewis’ solution to was to abandon the tried-and-true principle that persons can be counted by counting heads. Since there are two persons after fission, there were two all along, even though, before fission, they occupied the same body and were unaware of their duality. (Bizarre though it sounds, I support Lewis’ solution as one that inflicts the least damage to the traditional concept of a person.) Thomas Metzinger’s analysis led him to conclude that “no such things as selves exist in the world.”

In his book, I am You, Daniel Kolak offers yet another radical theory of personal identity: There is only one person, and that person is all of us.  What are commonly understood to be boundaries between individuals, he says, do not “merit the metaphysical significance ordinarily accorded to them.”

Our borders do not signify boundaries between persons. We are all the same person. [Kolak, 2010, p 1] Continue reading “Kolak: I Am You”

Persons in Law

We cannot understand the self by examining people in isolation.   Too many important aspects of personhood only appear in a social context.

Thomas Metzinger’s work describes the self-model in which our ideas about ourselves are rooted.  The model is (usually) transparent, in that we operate through it without (usually) any awareness of a distinction between the model and the underlying reality.  It is a model to which we have a profound emotional attachment—most of us care, deeply, about ourselves in the past, present, and future.  As a result, our self-models are motivational.  They spur and shape our actions.  We evaluate possible courses of action by putting our self-models through various simulations, and responding emotionally to the different outcomes we imagine.  The research of Antonio Damasio has begun to show how our emotions must inform our executive decision-making processes in order for us to make what are commonly recognized as ‘rational’ decisions.

Most of what Metzinger and Damasio have to say about the self is as true of isolated individuals as of human beings immersed in society.  But a case can be made that the concept of the self could only have emerged in a social context.   I have argued that our concepts, particularly the entities recognized by our ontology, reflect what is important to us. The spatio-temporal boundaries between ‘things’ are artificial, not natural; they do not exist in nature, but are imposed upon nature by human beings.   A person is an entity whose boundaries roughly coincide with those of a human biological organism.  A person is commonly considered to begin sometime around birth; sooner in some traditions, later in others.  The person is usually thought to persist until biological death; but many people believe that it continues much longer than that; and some believe that if the organism is sufficiently damaged, then the person may cease to exist before its organism dies.

Among other things, a person is a unit of moral and legal responsibility—a bearer of enduring rights and privileges, duties and obligations, merits and demerits, assets and liabilities, debts and credits.  Those attributes of individual persons result from, and depend on, the fact that individuals are members of a larger society.  If a human being is isolated for a long time from other human beings, legal obligation disappears from his life, and moral obligation, if it does not entirely disappear, is vastly curtailed.  I would not go so far as to say that an isolated human being ceases to be a person; only that certain central and important aspects of personhood simply disappear from his or her life.  Having moral and legal rights and obligations is a central and important aspect of personhood.
