"But behold, this soul of thought frequently has the ascendancy over the animal soul. The thinking soul orders its hands to grasp, and they grasp. It does not tell its heart to beat, its blood to run, its chyle to form; all these things happen without it: so here we have two perplexed souls which are hardly masters in their own house."
