I suppose the most important thing, the heaviest single factor in one's life, is whether one's born male or female. In most societies it determines one's expectations, activities, outlook, ethics, manners - almost everything. Vocabulary. Semiotic usages. Clothing. Even food. Women... women tend to eat less... It's extremely hard to separate the innate differences from the learned ones. Even where women participate equally with men in the society, they still after all do all the childbearing, and so most of the child-rearing.
Ursula K. Le GuinHe had grown up in a country run by politicians who sent the pilots to man the bombers to kill the babies to make the world safer for children to grow up in.
Ursula K. Le GuinWithout war there are no heroes. What harm would that be? Oh, Lavinia, what a woman's question that is.
Ursula K. Le GuinThere is neither source nor end, for all things are in the Center of Time. As all the stars may be reflected in a round raindrop falling in the night: so too do all the stars reflect the raindrop. There is neither darkness nor death, for all things are, in the Light of the Moment, and their end and their beginning are one.
