Within the university... you can study without waiting for any efficient or immediate result. You may search, just for the sake of searching, and try for the sake of trying. So there is a possibility of what I would call playing. It's perhaps the only place within society where play is possible to such an extent.
I am not impressed by the Ivy League establishments. Of course they graduate the best -- it's all they'll take, leaving to others the problem of educating the country. They will give you an education the way the banks will give you money -- provided you can prove to their satisfaction that you don't need it.
