The Necessity of Genetic Components in Personal Identity The reason this is important, is that it then establishes some other more interpretive things. That is to say, you cannot in reality have a person born under different circumstances (prior to the point of conception) because those circumstances would almost certainly result in a different set of gametes, and hence a different person than the one that is reflecting back on the altered history. — schopenhauer1
This is incorrect. There are various factors that happen prior to conception that contribute to development.
Circumstances are effectively ‘the environment’ and given that the environment is forever changing what happens prior to conception has an obvious effect on items within said environment. The only way out of this is belief in some form of dualism.
So saying that person A is person A is basically a waste of time. There is nothing here and I confused why there is a needless back and forth debating why YOU is important as some non-existent being that is never non-existent because YOU exist. It is just words used to screen clarity I feel.
That a thing cannot itself is kind of true, but to say that something cannot be effected by anything else is rather silly.
