Parfit’s Non-Identity Problem

One of the most talked about arguments in philosophy is Derek Parfit’s Non-Identity Problem. Put simply, the problem is whether it is ever permissible to bring someone into existence who would lead a life that, overall, an impartial observer would consider to be worse than not existing at all. This is a difficult problem to answer: as Parfit notes, any answer must take into account both empirical facts and moral beliefs.

The Non-Identity Problem has its roots in Parfit’s concept of the “repugnant conclusion”. This is the idea that it is better to bring into existence a large population of people, who lead lives that are barely worthwhile, than it is to bring into existence a smaller population of people who lead lives that are considerably better. Although these numbers would seem to be counterintuitive, it is important to remember that the lives of the people in the larger population have some value—even if overall it may still be worse than no one existing at all.

Parfit’s own solution to the Non-Identity Problem was to reject the repugnant conclusion, and instead suggest that the ethical option would be to produce a population of people whose lives are overall better than if no one had existed at all. In order to do this, however, we must first be able to determine whether a life has greater or lesser value when compared to the alternative of not existing.

This is where Parfit introduces the concept of “transcendental preference”. Basically, this means considering whether, on balance, a person might prefer any altered state of existence that he or she might be offered—including the null state of not existing. In essence, this requires that Parfit acknowledge that despite whatever values and preferences an individual may hold, they must also take into account the objective value of any given life as it would be judged by an impartial observer.

Having considering these points, Parfit then offers a controversial solution to the Non-Identity Problem. He suggests that in cases such as this, bringing someone into the world who will lead a bad life may be the best course of action for society. This is based on the fact that allowing someone to suffer a bad life is better than allowing no one to exist at all. This means that, in effect, it may be permissible to bring someone into a state of existence which will, overall, be worse than nonexistence.

Of course, this solution is not without its drawbacks. To begin with, it puts immense stress on the concept of “transcendental preference”. To accept this solution, one would have to consider the value of a life, not only in comparison to others, but also against the alternative of existence in general. Moreover, this solution also seems to denigrate the value of the suffering experienced by an individual, as it implies that bringing someone into a state of suffering can be considered permissible if, on balance, society would benefit.

In conclusion, Parfit’s Non-Identity Problem is a difficult and controversial one to solve. The suggestion that it may be permissible to bring someone into the world who leads an overall bad life is not an easy one to accept, as it goes against our moral intuition. However, whilst this may be distasteful, it may still be the only option in some cases—particularly, ones in which the population of people who would lead an overall good life is too small. Ultimately, it is a difficult concept to grapple with, and one which will no doubt continue to divide opinions.

The sorites paradox, also known as the paradox of the heap, is a challenge in philosophical logic first introduced by the Ancient Greek philosopher Eubulides of Miletus in the fourth century B.C. The paradox states that if you have a pile of grain and a single grain is taken away from it, the pile remains a pile, and the process can be repeated indefinitely. If the process is repeated, eventually the pile will be emptied of all of its grains, yet the pile must still remain a pile.

The paradox has been debated for centuries, with little consensus among philosophers as to how to solve it. One approach is to accept the paradoxs apparent logical inconsistency and assume that such puzzles do not correspond to reality. This would suggest that the concept of a “pile” is a subjective one, and is therefore not subject to absolute definitions.

Other philosophers have suggested various ways of resolving the paradox. For instance, some have argued that there is a threshold number of grains beyond which a pile ceases to exist. This can be seen in the statement “A pile is a collection of more than three grains of wheat”. This would imply that while the removal of one grain of wheat still results in a pile, once the pile reaches a number of grains below three it ceases to be a pile anymore.

Finally, some have argued that the paradox is only a problem if you consider the gradual removal of grains one by one. They suggest that if you consider each grain of wheat as an individual entity, then the gradual removal of grains does not necessarily lead to an empty heap. That is to say, the removal of a grain of wheat does not necessarily mean that the remaining collection is not a pile.

Regardless of which interpretation one accepts, the sorites paradox will undoubtedly continue to perplex philosophers for centuries to come.
