In our contemporary world, no one can think or work with a single picture of what a family is. No one can fit all human behavior, all thought and feeling, into a single pattern.

Ninety-nine percent of the time humans have lived on this planet we've lived in tribes, groups of 12 to 36 people. Only during times of war, or what we have now, which is the psychological equivalent of war, does the nuclear family prevail, because it's the most mobile unit that can ensure the survival of the species. But for the full flowering of the human spirit we need groups, tribes.

No skill, no special apti­tude, no vividness of imagination or precision of thinking would go unrecognized because the child who possessed it was of one sex rather than the other. No child would be relentlessly shaped to one pattern of behavior, but instead there should be many patterns, in a world that had learned to allow to each individual the pattern which was most congenial to his gifts.

Each home has been reduced to the bare essentials -- to barer essentials than most primitive people would consider possible. Only one woman's hands to feed the baby, answer the telephone, turn off the gas under the pot that is boiling over, soothe the older child who has broken a toy, and open both doors at once. She is a nutritionist, a child psychologist, an engineer, a production manager, an expert buyer, all in one. Her husband sees her as free to plan her own time, and envies her; she sees him as having regular hours and envies him.

Warfare ... is just an invention, older and more widespread than the jury system, but none the less an invention.

Man's most human characteristic is not his ability to learn, which he shares with many other species, but his ability to teach and store what others have developed and taught him.

To demand that another love what one loves is tyranny enough, but to demand that another hate what one hates, is even worse.
