Closely connected with this conception of “another world” is the conception which man forms concerning his own nature. There are few races of mankind among whom we do not find in one shape or another the belief in a second self. Sometimes this second self is in all respects a reflection and image of the living self, like the images of those we see in our dreams; and it is more than probable that dreams first suggested it. Sometimes it is a mere speck of grey vapour, which may owe its origin to the breath which issues from the mouth and seems to forsake it at death, or to the misty forms seen after nightfall by the savage in the gloom of the forest and by the edge of the morass. At times it is conceived of as a sort of luminous gas or a phosphorescent flash of light, such as is emitted by decaying vegetation in a damp soil. Or, again, it may be likened to the bird that flies to heaven, to the butterfly which hovers from flower to flower, or even to insects like the grasshopper which hop along the ground. But however it may be envisaged, it is at once impalpable and material, something that can be perceived by the senses and yet eludes the grasp. The Egyptian theory of the nature of man in the historical age of the nation was very complicated. Man was made up of many parts, each of which was capable of living eternally. The belief in his composite character was due to the composite character of the people as described in the last lecture, added to that conservative tendency which prevented them from discarding or even altering any part of the heritage of the past. Some at least of the elements which went “to the making of man” were derived from different elements in the population. They had been absorbed, or rather co-ordinated, in the State religion, with little regard to their mutual compatibility and with little effort to reconcile them. Hence it is somewhat difficult to distinguish them all one from another; indeed, it is a task which no Egyptian theologian even attempted; and when we find the list of them given in full, it is doubtless to secure that no component part of the individual should be omitted, the name of which had been handed down from the generations of old.
