In my opinion the search for knowledge will probely never bring you happiness. I spend alot of time studing the dynamics of society (its a hobby so I dont really know what Im talking about). But I have always felt that people are controlled by two forces, your own wishes and those of society around you.
People have a prebuilt in yearning for knowledge, this is why we can never gain happiness from knowledge. Because invariably the more we learn the more apparient it becomes how little we really know, and the more we specilise in one area to learn all we can about it, the more potential we have to give up to learn things about other areas. And maybe you could acheive personal happiness if you were to just give up the persuit of knowledge. But we humans are more than just one, as a group we feel the need to learn. So that our children can become one step closer to acheive perfect knowledge and finally be free of the urge to know more.
I don't really belive that as a singular person a human is much better than an animal, it is our society that allows us to do what we can do. Because of the people who never gave up the persuit of knowledge that we are where we are today. The may have never been happy but thing of all the avoid sorrow because of the discovery of a cure to polo, or any of the other diseases we have avoided. In the end maybe we arnt meant to be happy as an indvidual, but as a society. And maybe some people feel the need to learn more than others, or maybe some people just havn't discovered (or maybe never will) whatever it is that they are predisposed to learn about, for me its computers. I consider myself one of the lucky ones for having discovered my area, a hundred years ago I wouldn't have have been so lucky. And maybe a hundred years from now the soriety girls you consider to be so stupid will discover their roles.
