Hate to break it to all the people who are so
loving my previous post on how NOT to structure an argument in favor of gay rights
, but there is no such thing. As separate and distinct notions of "nature" and "nurture," that is. Reality, as reality most often is, is a lot more complicated than that. Who we are is actually a sum total of the complex interactions between the two. Our genes affect what sorts of environments we choose and what sorts of changes we make to them, and our environments in turn affect the expression of our genes--in a continuous circle that knows no beginning and no end.
So, for example, suppose that alcoholism has a genetic component and that certain people are genetically predisposed to it. Obivously, they ain't gonna be alcoholics, no matter how "predisposed," if there isn't any alcohol around! And of course human beings were not created with a bottle of booze in hand. Thanks to other genes that predispose us to intelligence and creativity, we invented it somewhere along the line...and, in so doing, gave that genetic component that predisposes some people to addiction to alcohol that was already there but not making any alcoholics up until that point the fuel to necessary to now make those alcoholics en masse!EDIT:
If this news is new to you, I suggest taking a few minutes, or, depending upon your intellectual mileage, a few weeks, to digest it. Seriously.
