Whereby we shall eschew a very considerable error which many have fallen into so far, that I believe it the cause of hindering the passions, and other things which belong to the soul from being explained hitherto. It is this, that seeing all dead bodies are deprived of heat, and consequently of motion, people imagine the absence of the soul wrought this cessation of motion and heat, and so erroneously conceive that our natural heat, and all the motions of our body depend on the soul: whereas indeed the contrary should be supposed that the soul absents itself in death, only because this natural heat ceases, and the organs which seem to move the body are corrupted.
