Kripke on 'I'
Ideally, when ‘I’ am ostended, we desire to pick out the necessary factors of my being who I am, and in that, only one of me. More clearly put, for someone to refer to me they intend to point verbally to the one thing that fulfills all of the criteria of my identity. Is there something that can be established from this position about how we assign identity. It would appear primarily that a position like this is almost entirely question begging. I have assumed a definition of identity, based on the nature of a person, in order to assert that a person has an identity. Below I will attempt to put this objection more clearly.
Firstly, in a discussion of personal identity, I desire to know if there is any such thing as personal identity. On the basis of this information I can discover how to apply my knowledge – how to point to something and then later to the same thing by performing the same action, i.e. by using a proper name to pick out person. In the argument briefly outlined above, someone can point to me by knowing that I fulfill the criteria of being me, and on that basis define identity.
However, this argument does lead to a method of pointing to the same individual through time with some universal designation. This designation is formulated as a rigid designator. A rigid designator is essentially a proper name (it can also be a ‘natural kind term’, but that is not important for my discussion). Importantly, a rigid designator, once established, will always be ostentation to the same individual. Kripke sets forward this idea in ‘Naming and Necessity’.
This works initially by setting up a modal system on the basis of possible worlds. If we consider an individual, they have necessary and accidental properties. More abstractly, we can consider that in every possible world where I consider that individual, they will have the same combination of necessary properties, but different combinations of accidental properties. This is not to say that there are a multitude of actual other worlds. Instead this is designed to signify that every time I perceive of a thing, there are some things that it must always retain, and other things that I can consider may be different. An example of this can be found if I consider, say, a bench. When I look at that bench I can see that it is made of wood, has four legs and sits just so in the room. In this world, that is how I can identify the bench. For all of the properties of the bench, there are some that are necessary and some that are contingent. Necessary properties are such that to change them would change the ‘identity’ of the object itself. Properties that are accidental can be different and leave the original nature of the individual unchanged. So the possible worlds argument requires this; for any object (‘thing’) it has some necessary properties – things that are the same of that object in every possible world, where that object actually exists – and some contingent properties – properties of the object that occur in only a portion of all possible worlds.
Through convention a person is assigned a name, and importantly, that name is a rigid designation. To this end, if we refer to someone by name then we are guaranteed to pick out the person to whom that name refers in every possible world, where that person exists.
But what if we are not pointing to the individual directly, instead we are referring to their memories, or their social status (to take an example from chapter 1 & 2 respectively). In this way the name that we are using is a description of that person, not an ostentation. Kripke calls this a non-rigid designator, and importantly here, non-rigid designator’s do not pick out the same individual in all conceivable cases. Identity, in its form of being an object identical with itself cannot hold here. In essence, we can assign a name, which we then define to be identical with itself in our use of that name within language. However, there is no way in which we can describe an individual which leads to this same result. It would appear that in language, identity is simply convention.
