History

• First, tribes: tough life.
• The defaults beyond the intimate tribe were violence, aversion to difference, and slavery. Superstition: everywhere.
• Culture overcomes them partially.
• Rainfall agriculture, which allows loners.
• Irrigation agriculture, which favors community.
• Division of labor plus exchange in trade bring mutual cooperation, even outside the tribe.
• The impulse is always there, though: "Kill or enslave the outsider."
• Gradual science from Athens' compact with reason.
• Division of labor, trade, the mastery of knowledge, plus time brought surplus, sometimes a peaceful extended order and, rules diversely evolved and, the cooperation of strangers - always warring against the fierce defaults of tribalism, violence, and ignorance.
• No one who teaches you knows what will happen.
