At time 1, there is a person. At a later time 2, there is a person. These people seem to be the same person.
Indeed, these people share memories and personality traits. But there are no further facts in the world that make them the same person. Parfit's argument for this position relies on our intuitions regarding thought experiments such as teleportationthe fission and fusion of persons, gradual replacement of the matter in one's brain, gradual alteration of one's psychology, and so on.
For example, Parfit asks the reader to imagine entering a "teletransporter," a machine that puts you to sleep, then destroys you, breaking you down into atoms, copying the information and relaying it to Mars at the speed of light. On Mars, another machine re-creates you from local stores of carbon, hydrogen, and so oneach atom in exactly the same relative position. Parfit poses the question of whether or not the teletransporter is a method of travel—is the person on Mars the same person as the person who entered the teletransporter on Earth?
Certainly, when waking up on Mars, you would feel like being you, you would remember entering the teletransporter in order to travel to Mars, you would even feel the cut on your upper lip from shaving this morning.
Then the teleporter is upgraded. The teletransporter on Earth is modified to not destroy the person who enters it, but instead it can simply make infinite replicas, all of whom would claim to remember entering the teletransporter on Earth in the first place. Using thought experiments such as these, Parfit argues that any criteria we attempt to use to determine sameness of person will be lacking, because there is no further fact.
What matters, to Parfit, is simply "Relation R," psychological connectedness, including memory, personality, and so on. In these ways he goes some way to meet the problem of theoretical authority — though not, I believe, far enough. In starting with practical reason, and in some of his methods of argument, Parfit agrees with the Victorian moral philosopher Sidgwick, whom he greatly admires.
Keynes thought that Sidgwick lacked intensity and was suffocated by respectability. Parfit would deny these charges against Sidgwick, but whether he is right in that or not, the charges certainly do not apply to this strange and excitingly intense book.

It is in four parts. In the first, Parfit considers what it is for a theory of rational action to be, in any of various ways, self-defeating.
He deals, very subtly, with such problems as this: The best outcomes are more likely to be produced if each person acts from motives which do not involve thinking directly about the outcome. This has been thought to be a problem for consequentialist theories of this kind. Parfit insists that it is not, and that this result does nothing to refute the theory that we should produce the best outcomes all round.
The name of the effective altruism movement was corrected. Parfit divides Reasons and Persons into four loosely related parts, which run as follows: Only by assaulting it on both fronts can we discover its true worth.

That total well-being should not matter when we are considering lives worth ending is hard to accept. For instance, the principle implies that for any population consisting of very good lives there is a better population consisting of just one person leading a life at a slightly higher level of well-being Parfit chapter By thinning out the connection between my present and future selves, Parfit hoped to reciprocally fatten up the connection between me and at least some other people.
A woman suffers from an illness which means that, if she gets pregnant now, her child will suffer from a permanent handicap. Parfit made a similar argument against average utilitarian standards. On What Matters In his second book, Parfit argues for moral realisminsisting that moral questions have true and false answers.
If a married woman divides should we arrest the husband of these women for practicing bigamy illegal in all 50 states and many other countries? Here we are comparing one population where everybody enjoys very high quality of life with another population where people either have very low positive welfare or very negative welfare any level of horrible suffering.
But here lies the issue: The value of a population is calculated by summing these differences for all individuals in the population.
