To a certain extent, therefore, the general incapacity for abstract thought which distinguished the Egyptians did not hold good of the priestly colleges. But even among the priests the abstract was never entirely dissociated from the symbol. Symbolism still dominates the profoundest thoughts and expressions of the later inscriptions; the writer cannot free himself from the sensuous image, except perhaps in a few individual cases. At the most, Egyptian thought cannot rise further than the conception of “the god who has no form”—a confession in itself of inability to conceive of what is formless. It is true that after the rise of the Eighteenth Dynasty the deity is addressed as _Kheper zes-ef_, “that which is self-grown,” “the self-existent”; but when we find the same epithet applied also to plants like the balsam and minerals like saltpetre, it is clear that it does not possess the abstract significance we should read into it to-day. It simply expresses the conviction that the god to whom the prayer is offered is a god who was never born in human fashion, but who grew up of himself, like the mineral which effloresces from the ground, or the plant which is not grown from seed. Similarly, when it is said of him that he is “existent from the beginning,”—_kheper em ḥat_,—or, as it is otherwise expressed, that he is “the father of the beginning,” the phrase is less abstract than it seems at first sight to be. The very word _kheper_ or “existent” denotes the visible universe, while _ḥat_ or “beginning” is the hinder extremity. The phrase can be pressed just as little as the epithet “lord of eternity,” applied to deities whose birth and death are nevertheless asserted in the same breath. Perhaps the most abstract conception of the divine to which the Egyptian attained was that of “the nameless one,” since the name was regarded as something very real and concrete, as, in fact, the essence of that to which it belonged. To say, therefore, that a thing was nameless, was equivalent to either denying its existence or to lifting it out of the world of the concrete altogether.
