Psychoanlaysis

I fould reading Eagleton's version of Freud's theories very interesting. I like the way in which he presents information and outlines Freud's entire realm of theories in a matter of a few pages. I have read various texts by Freud before but Eagleton put everthing together.
One of Freud's most popular theories is that of the Oedipus Complex. I was surprised, however, to read that girls can also have one. I was unaware of this. Eagleton says, "the boy's close involvement with the mother's body leads him to an unconcius desire for sexual union with her, whereas the girls, who has been similarly bound up with the mother and whose first desire is always homosexual, begins to turn her libido towards the father" (Eagleton 134). In other wrods, the girl's sexual tendencies are first always homosexual since she is also breast fed and learns to suck the mother's milk. However, there are so many other things that happen in a little girl's anatomy that are not related to homosexuality or sexuality at all. This is a complicated concept and I'm still trying to fully understand it. Why can a girl not have a mother and daughter relationship? Why does everything for Freud revolve around sexual tendencies? Is this idea universal? Or, was he talking mostly about Western Philosophy?
Though I find Freud's claims generic and broad, I do give him credit for being the first one to put these thoughts on paper. There is no doubt there were other people who had thought about these ideas. But since sex is a touchy subject, people do not want to touch it (no pun intended). He is the reason we have an entire field of psychology. Of course Freud cannot be credited with everything, but I do believe that he was the first one brave enough to write down what other males in Vienna at his time (and at other times elsewhere) were thinking. Before Freud, society would not have had such ways of thinking. But his works also beg the question: would we have fewer people do crimes based on sexual desires? I watch reruns of "Law and Order: SVU" when I get time; this program deals with sexually based offenses. There are some very extreme and perverted cases of sexual abuse, rape, etc. Of course Freud is not responsible for some people becoming creeps; quite the contrary. If Freud didn't publish his works, we would not have been able to assess and analyze people's behaviors and would just call these people (like the ones on SVU) "crazy" rather than seeing their crimes and behaviors as problems and helping them resolve such problems.
