The Problem of Personal Identity
In the essay written by John Perry called “Will Tommy Vladek Survive?” Perry presents a very controversial topic. In this story Tommy Vladek is considered brain dead but his body is still totally functional. There is another child in the story who has had an accident, and his body is completely destroyed. The child’s body that is completely destroyed still has perfect brain function, and the doctors can put his brain into Tommy’s body. Perry presents different views on the topic of who will survive the operation, Tommy who is providing the body, or Sam who is providing the brain?
When looking at the main question at hand. Who is Harry Vladek likely to bring home from the hospital?

So in this case, if you had twins you would say that they are the same. Some philosophers say that we are never identical from moment to moment, because we
are always changing and having new thoughts and memories in our brains every second. Personal identity cannot help with the Tommy Vladek case, because you can say that Tommy’s physical appearance has not changed at all. But...
