“A hen is only an egg's way of making another egg.” — Samuel Butler.
“Thus, a young woman aroused by sexual desire is not necessarily listening to her own essential, unique, individual needs when she decides to follow the bent of her instincts. She is actually doing what she was made to do as a member of biological species, serving the needs of the genes that have programmed her behaviour for their own ends. It is true that she would be experiencing pleasure if she satisfied her desire; but then pleasure is simply the bait that evolution has devised to entice her to reproduce. And of course, if she give full rein to her sexual interests, she could create a great deal of trouble in the future.
On the other hand, if the young woman decides to curb her desire in order to finish a physics assignment or to work on a fund-raising drive, it could again be said that she is not serving her own interest, but obeying the interests of the social system that she has internalized in the form of values. It seems, then, that whether she acts on her instincts or not, she ends up being manipulated by outside interests — either genetic or social.” — The age of choice
