Interesting tidbit in the book: many traditional cultures to this day (African, Amazonian, Indonesian) believe the fetus is formed from sperm and the woman must have frequent sex before and while pregnant to start and grow the baby. From several men. This reduces the chance that we deal with in "mono" cultures of having an infertile husband who can't reproduce. Also, all these men will provide meat for the mother and child, making her assured of food from not one man, but several.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
