It is chiefly in their ideal that they differ. The materialist thinks that all the consciousness and intelligence that one sees in man is the natural development of life. The mystic says that this consciousness or intelligence is the same as the unlimited consciousness or intelligence which is put into different channels, and that from this intelligence that existed in the beginning all manifestation has come. Picturing the unlimited consciousness or intelligence as the ocean, the consciousness or intelligence of man is like a drop. Thus the materialist sees the intelligence of man as the natural development of humanity, while the mystic sees it as the divine essence, as one, as the source of all things.
