Does changing my brain mean changing who I am?
I believe in some type of consciousness that surpasses matter. But in everyday life my emotions, thinking ability, and creativity are profoundly influenced by the physical qualities of the lump of soggy goo that lives inside my skull. It requires fuel. It responds to its chemical environment. When I get sick, it loses function. When I took drugs, it responded to that. And when that lump of soggy goo developed bipolar disorder, it changed my life on so many levels I can’t imagine a hypothetical self without it now.
There’s a novel in which the protagonist, an old man, gets his brain transplanted into the body of a young, beautiful woman. He had his original brain and all its memories, but that brain was now bathed in a different chemical soup. The author chose to have the character, a heterosexual man in his old body, become bisexual with a strong preference towards men. The explanation given was twofold: a bond with the previous owner of the body, and the influence of female hormones.
Do I think that explanation is realistic? No, and I think some of the author’s attitudes about gender are quite dated, but it is food for thought. How much of our sexuality, for example, lies in the body, how much in the brain, and how much in a mysterious entity that is neither? Extrapolating, how much of my very identity lies in each?
I don’t mean to define myself by a diagnosis in a self-defeating manner, nor do I mean to discount the role of attitude and insight in my quality of life. I’m simply saying that understanding that I’m coping with a certain kind of brain can help me structure and create a life that suits it as well as possible. I know there’s a huge amount I can do to influence it–but I’m still starting with my individual lump of soggy goo.
