In response to Kelsey...

Kelsey asked: How big of a role do you think nature and nurture play in personality? How about sexuality?

I've always thought that nurture overpowers nature, especially in terms of personality. I believe that one's personality, or the way in which one acts and thinks, is determined by the events in one's life and the way in which one reacts to said events. (This, of course, must take into consideration people with mental disorders, because they are genetically predetermined to have certain traits or thoughts.) If a baby were kept in isolation from birth, it would most surely not have a pre-existent personality. It would be irrecognizably human, even. Similarly, I believe that a child who grows up in a certain culture or environment would be inevitably shaped by said culture. Granted, there are bad people in good situations and good people in bad situations. I think this is where nature comes in. Your reactions and emotions are generally involuntary. So I think there must be some sort of synthesis between nature and nurture in order to foster a human's personality.
As for sexuality, I will consciously contradict what I just said about nurturing personality because I believe that sexuality is something intrinsic in each human. I don't think you can "raise" your child to be gay, and I don't think you can raise a child to be straight. There are plenty of same sex couples with children who are not gay, and heterosexual couples whose children are gay. Sexuality and attraction are such basic, primal instincts. You can't "learn" how to be attracted to a certain sex. People like who they want to like because something in their heart (or genetalia) tells them so, not because society does.

Q: Do you think the concept of eugenics is in any way justifiable? Does it relate to they ways in which modern science is attempting to choose a baby's gender, eye color, or other physical traits?
