From the book 'A Brave a New World by Aldous Huxley'...
On the one hand there are the People of the World State, who are conditioned. Nearly all main characters in Brave New World are from this society. When they are born, they are educated and conditioned through sleep teaching and electro shock therapy. Through this, the World State is able to ‘form’ the people, so that things like free-thought and the fear of death don’t exist.
Also sexual and reproductive habits are formed in this education. For example, the children play erotic games in the hatchery and conditioning centre. For them it is normal that children do such things and have fun doing them.
