What makes me me? That is to say, what makes me different from another person? It's easy to answer in a general term. You are you, with different thoughts, emotions and DNA. But it's at DNA where the answer becomes confusing and tricky for me. As far as I am aware, DNA is the information of you, of which everything about you is first started, and where what you're current situation is stems from. Then, of course, it is probably correct to say that an exact matching strand of DNA will lead towards the exact same results after you are "born" or created (at least, to stuff that are not environmentally depending). Now, as far as i know, your brain, thoughts and consciousness all derived genetically and are not affected environmentally. So, and I'm sure this has been discussed a lot, if you where to clone yourself, you would expect somebody who looks exactly the same as you to be born. But then, what about the psychological side of it? Seeing as we both come form the same source, and all the information that makes us us is the same, how come he has a different consciousness than me? Why is it that he makes decisions independently from me, even though we are, in theory, the same? In short, what is it that makes him him, and not me? Why can I control myself and not control him? Why can I see my thoughts and not his? There must be something that he has that I do not have, yet, we are identical, because our DNA was the same. It's almost a kind of separate presence that allows me to be me, which allows me to see through my eyes and here through my ears, think my thoughts and control my hands. This exact clone of me must somehow have this as well, but it's not me, because I am not him, I am me. And seeing as he has my DNA, I can't get my head around why he would be different. Something must have changed, something must be different between us to make him different.
Thanks in advance.
