Besides this, the genius and structure of the Egyptian language are such
as to preclude the possibility of composing in it works of a
philosophical or metaphysical character in the true sense of the words.
In spite of these difficulties, however, it is possible to collect a
great deal of important information on the subject from the funereal and
religious works which have come down to us, especially concerning the
great central idea of immortality, which existed unchanged for thousands
of years, and formed the pivot upon which the religious and social life
of the ancient Egyptians actually turned. From the beginning to the end
of his life the Egyptian's chief thought was of the life beyond the
grave, and the hewing of his tomb in the rock, and the providing of its
furniture, every detail of which was prescribed by the custom of the
country, absorbed the best thoughts of his mind and a large share of his
worldly goods, and kept him ever mindful of the time when his mummified
body would be borne to his "everlasting house" in the limestone plateau
or hill.

The chief source of our information concerning the doctrine of the
resurrection and of the future life as held by the Egyptians is, of
course, the great collection of religious texts generally known by the
name of "Book of the Dead." The various recensions of these wonderful
compositions cover a period of more than five thousand years, and they
reflect faithfully not only the sublime beliefs, and the high ideals,
and the noble aspirations of the educated Egyptians, but also the
various superstitions and childish reverence for amulets, and magical
rites, and charms, which they probably inherited from their pre-dynastic
ancestors, and regarded as essentials for their salvation. It must be
distinctly understood that many passages and allusions in the Book of
the Dead still remain obscure, and that in some places any translator
will be at a difficulty in attempting to render certain, important words
