Such men alone are my readers, my proper readers, my preordained readers. Of what account are the rest? The rest are simply... humanity. One must be superior to humanity in power, in loftiness of soul- in contempt.
The soul is the cause or source of the living body. The terms cause and source have many senses. But the soul is the cause of its body alike in all three senses which we explicitly recognize. It is (a) the source or origin of movement, it is (b) the end, it is (c) the essence of the whole living body.
