You are only thinking all this because of ignorance. If you had read a couple of books about psychology, artificial life, evolution etc. you wouldn't cling so much to your belief in magic and fairy tales (which is what it would seem like to you after having read these books).
I have read a LOT about what a person is, although - mostly from the wonderful period of time when psychology was a part of philosophy and true to its name (it dealt with the "psyche", the soul). I've also had half a year of "Psychology 101 for philosophers" and half a year of "philosophycal problems in biology", where I was forced to read modern, empirically-focused text on a regular basis.
So - yeah. Psychology is not major, but I'm no ignorant either.
I was trying not to disrupt the discussion, yet at some point it became apparent that in most cases modern psychology can "explain" everything, yet predict next to nothing. Better yet - in most cases both action A and action ~A were considered rational, while different theories were applied to explain why. While it doesn't prove anything straight off the bat, it was sometimes hilarious to observe.
For your own amusement: we were to read a part of Geoffrey Miller's "The Mating Mind" (one of those wonderful books that might render the reader asexual if taken seriously), where he reminds the readers that the stereotype of "Man: the Hunter" had been proven wrong quite some time ago in the book "Woman: the Gatherer". Basically - in those wonderful, primitive times, men WERE hunting, yet most of the time they were NOT successful at it. To top it all up - they were hunting huge beasts, where their chances were minimal, while women were hunting bunnies and gathering food. Not only hadn't men provide the basic form of nutrition - a successful hunt was split among everyone in the group/tribe, so we can't even say that women traded sex for meat. In short - "hunting" was a prehistorical form of SPORT, entertainment. To further add insult to the injury - Miller claims that not only did women not find it irritating that they were the ones to gather food, hunt, take care of the kids, saw clothes, etc; they actually were attracted to those lazy bastards that were successful. At this point it's twisted, but conceivable, as we MAY find an evolutionary use for such behavior (despite of the fact that man taking less risks would provide a steadier "income"). What stunned me was the conclusion, that "this is why women find succesful sportsmen so attractive". They DO ? Really ?
My first thought was that there are very few people into sports (actively, at least) and those that are aren't exactly perceived as SO much more attractive (I know I can't back up this claim - but bear with me). Then, in a flash of understanding, one question came to my mind: is Miller American ? Why, YES, he sure is. And that explains a LOT, because I've heard a lot about how Americans treat sport (I sure you know this better than I do) - cheerleaders, high school baseball teams, etc. The problem is - it's NOT a universal behavior. It's culturally-dependent. I'd venture a guess that in Europe most sport fans are male and women... don't really care.
Of course - we could also discuss how poets, spiritual leaders, rich guys and men with power are found attractive by women, which leads to the conclusion that the Pope is the hottest hunk on the planet... but that's a lot more likely ;).
The point is - while physicists try to form laws (like gravity) that are universal and explain the world, empirical psychologists try to do the same with human behavior... and fail miserably, because for every "rule" they create there are hilariously counterintuitive cases. They mostly deal with this, saying that people who act differently are "insane". While this is a safe move, in the long run it suggests that the world's going more and more crazy.
Then again - I spoke a while ago with a girl who had a PhD in psychology, and she said that it's just the way things used to be... and it didn't work. As such, much to my appreciation, I heard that psychology finally starts to be aware that it deals with statistics, not universal laws. That is: it doesn't say "people must act this way" but rather "most people act like this".
