“Some people say that sex is basic and underlies all these other loves – love of friends, of God, of country. Others say that it is connected with them, but laterally; it is not their root. Others say that it is not connected t at all. All I suggest is that we call the whole bundle of emotions love, and regard them as the fifth great experience through which human beings have to pass.
When human beings love they try to get something. They also try to give something and this double aim makes love more complicated than food or sleep. It is selfish and altruistic at the same time, and no amount of specialization in one direction quite atrophies the other.”
E.M. Forster, Aspects of the Novel
