All of this would have been a startling and hugely stressful change for our ancient ancestors. Yes, on one hand there is suddenly more food and comfort and spare time than the species had ever known. But maddening complexity arises at every turn. Language explodes. Man evolves the ability to think in words, essentially creating an entirely new schematic for his brain with which he will create abstract thought for the first time. And along with it, questions. Man needs to understand his place in the universe, and his relation to his creator. But this is not the beginning of science. It is the birth of superstition. What he does not understand, he fills in with this newfound cognitive power. The universe that this man inhabits will be one born from the astonishing new power called “imagination.”
