It is possible to answer the question "Who am I?" depending on a person's particular beliefs. For example, it depends on what a person believes constitutes their personal identity, such as; personality, values, etc. This question can also be answered by determining what theory of personal identity someone believes in and what part of themselves they think persists over time. I believe that memories, personality, values ​​and lifestyle all play a key role in personal identity and the answer to the question, “Who am I?” I believe in a combination of body theory, memory theory and illusion theory. I believe that people stay the same physically, in their bodies, but their personality, values ​​and memories also play a role in determining who they are as a person. I also believe that people can constantly change, such as their personality or their values, but still technically be the same person. Say no to plagiarism.

The body theory states that: “According to this theory, we are identical to our biological bodies and persist over time as long as our bodies maintain functional organization.” I believe I am always myself because I am the same body all my life. For example, the body I was born into is the same body I am currently and will be the same body at any other time in my life. In the situation where a man is brain dead and the question: “Is he still the same person even in his vegetative state?” According to the body theory, the man in the situation is actually the same person because as long as he is alive, it does not matter if his brain is damaged. However I don't agree with this, I believe this man is a different person because he is not able to have thoughts of his own and cannot do any of his normal usual activities. There is also the problem, if I switched bodies with my sister, would she be me or would I still be myself just in a different body. I believe I would still be myself just in a different body because I would still have the same personality and memories that I had in my old body, just in a different body. I somewhat agree with the concept of memory theory. The theory of memory states that “I am identical to a person who existed in the past as long as I can remember at least some events experienced by that person”. In essence, memory theory indicates that if you have a memory of something you did in the past, then you are the same person you were during these memories. I believe that if a person has no memories, then he is not himself per se. For example, if a man has Alzheimer's disease is he the same person he was before he had Alzheimer's disease? I think the man is the same person as always because he is still in the same body and still has all the memories of his past and has just changed his personality due to Alzheimer's disease. According to memory theory, if I had memories from my childhood and remembered them at my current age, then I would be the same person. At the same time, if I remember my current memories when I am old, then I am the same person, however, if I am old and do not remember my childhood memories, then I am not the same person. I don't agree with this part of memory theory because it doesn't make sense that the current self is not the equivalent of the old, childhood self. I minimally agree with the concept of illusion theory. Illusion theory is the concept that the human body is constantly changing and does not exist.
