If you think about it, and this is something that has always stumped me a bit about mood/behavior altering prescription drugs, all of your actions and thoughts and emotions that you feel are YOU are still the results of the chemical makeup of your brain. That was genuinely what you were like, and I wonder if in the past you (Universal Ye), or society, would have found that so far outside the norm that it needed to be treated somehow. I guess I worry that, like my friend Maureen's concern over plastic surgery, we will collectively arrive at some sort of ideal average where everyone will gravitate. As a narrower range of emotion is acceptable over time we begin ostracizing or medicating a shrinking number of the kind of madmen and women that society needs.

If we are going to think of the undesirable parts of our personality as being chemical in nature we should also be thinking of the positive traits that way.  Anything else is a false separation. It makes it more difficult to tell when someone has a genuine problem and not just a personality quirk (remember, it's ALL chemical) and it makes it hard to draw the line in terms of what behavior society deems acceptable.

This is yet another issue that is greatly informed by 'sci-fi reasons.' I'm still not quite sure how to wrap my head around the brain chemistry/what is the real you problem, but general applications aside, I have big fears in a Brave New World/Equilibrium way.

Other issues which I contemplate with Sci-Fi Reasoning:
-DNA databases for criminals.
-Artificial intelligence in general
-Unmanned weapons systems in particular
-Genetically Modified crops
-Any sort of physics experiment which could potentially, upon activation, implode the Universe.
