Hence it is proved and verified that in man there is a power of discovery by which he is distinguished from the animals, and this is the spirit of man. The love of exaltation is one of the characteristics of man. An Arab child of ten years can manage two or three hundred camels in the desert, and with his voice can lead them forward or turn them back.

If we wish to deny everything that is not sensible, then we must deny the realities which unquestionably exist.
