Most philosophers writing about personal identity in recent years claim that what it takes for us to persist through time is a matter of psychology. In this groundbreaking new book, Eric Olson argues that such approaches face daunting problems, and he defends in their place a radically non-psychological account of personal identity. He defines human beings as biological organisms, and claims that no psychological relation is either sufficient or necessary for an organism to persist. Olson rejects several famous thought-experiments dealing (...) with personal identity. He argues, instead, that one could survive the destruction of all of one's psychological contents and capabilities as long as the human organism remains alive--as long as its vital functions, such as breathing, circulation, and metabolism, continue.

My purpose is to explore the possible lines of reply available to a defender of the neo‐Lockean position on personal identity in response to the recently popular ‘animalist’ objection. I compare the animalist objection with an objection made to Locke by Bishop Butler, Thomas Reid and, in our own day, Sydney Shoemaker. I argue that the only possible response available to a defender of Locke against the Butler–Reid–Shoemaker objection is to reject Locke's official definition of a person as a thinking, (...) intelligent thing and replace it with the concept of the self– the object of self‐reference – and that this response is equally obligatory for the neo‐Lockean in replying to the animalist. I explore other possibilities, including the position that there is no sense in talking about personal identity at all. (shrink)

Logical Atomism is a philosophy that sought to account for the world in all its various aspects by relating it to the structure of the language in which we articulate information. In _The Philosophy of Logical Atomism,_ Bertrand Russell, with input from his young student Ludwig Wittgenstein, developed the concept and argues for a reformed language based on pure logic. Despite Russell’s own future doubts surrounding the concept, this founding and definitive work in analytical philosophy by one of the world’s (...) most significant philosophers is a remarkable attempt to establish a novel way of thinking.

It no longer is true in a metaphorical sense only that a person can have a change of heart. We might grant this much — allow that a person may have one heart at one time and have another heart at still another time — and also resist the idea that a person can have a change of mind in anything other than a qualitative sense. In the discussion that follows, this standard view of the matter is called into question. (...) If the argument presented here is sound, it can happen both that one person has numerically different minds at different times and that different people have the same mind at different times. These possibilities, as I take them to be, call for reassessment of some well entrenched assumptions concerning personal identity and responsibility. In particular, they suggest that it may not be true that person A bears responsibility for making decisions person B previously made only on the condition that A is the same person as B. (shrink)

It is often said that the same particles can simultaneously make up two or more material objects that differ in kind and in their mental, biological, and other qualitative properties. Others wonder how objects made of the same parts in the same arrangement and surroundings could differ in these ways. I clarify this worry and show that attempts to dismiss or solve it miss its point. At most one can argue that it is a problem we can live with.

In this essay I explore the idea that the solution to some important problems of personal identity lies in the philosophy of language: more precisely in the nature of first-person reference. I will argue that the “linguistic solution” is at best partly successful.

Sydney Shoemaker argues that the functionalist theory of mind entails a psychological-continuity view of personal identity, as well as providing a defense of that view against a crucial objection. I show that his view has surprising consequences, e.g. that no organism could have mental properties and that a thing's mental properties fail to supervene even weakly on its microstructure and surroundings. I then argue that the view founders on "fission" cases and rules out our being material things. Functionalism tells us (...) little if anything about personal identity. (shrink)
