One thing that endures through time and change is one's brain; so perhaps the self is the brain. Give some good reason to think this idea isn't correct.

  1. One thing that endures through time and change is one’s brain; so perhaps the self is the brain. Give some good reason to think this idea isn’t correct.

The above is the account of the powerful critisism to the body theory that states that the self is the body- i.e. each person is identifiable on the basis of physical and biological continuity. So, we can assume that the body theory is false and the above statement is true if we carry out a ‘survival test’. By removing one person’s brain and implanting it into another person’s body, it is the brain that will determine the ‘I’ of the body. Therefore, the ‘I’ or the person is the brain.

But still no scientific fact would state that the transplanted brain would determine the self of the body.

People go through drastic psychological changes in their lives- they can convert to different religions, acquire different tastes in music, literature, start to possess different moral values and norms. Furthermore, we can agree that a person in his childhood is not the same person as he would be in the older years. Even though our brain remains the same, we may become ‘different’ people to what we used to be. So, there probably exists a different self at any different point in time. If that is so, can we not say that the self of the person is separate from the brain.

On the other hand we may argue that our brain has such a complicated structure that no matter how many changes we go through we still express of our versatile self which is the brain.

The brain is just a bodily organ, just like the heart, or an arm. Psychological similarities of two people would not signify that they are one and the same self.

But then would not it be true to say that the death of the brain would signify the death of the ‘physiological base of what is crucial to personhood,’ the death of person himself?

Let us consider the following table:

Social and Biological Life (Table)

                         Socially Alive                       Socially Dead  

                   

Biologically    U.S.: All conscious           U.S.: fetuses and ...
