The tree of life was symbolic of communion with God and of man’s dependence upon him. But this, only because it had a physical efficacy. It was sacramental and memorial to the soul, because it sustained the life of the body. Natural immortality without holiness would have been unending misery. Sinful man was therefore shut out from the tree of life, till he could be prepared for it by God’s righteousness. Redemption and resurrection not only restore that which was lost, but give what man was originally created to attain: _1 Cor. 15:45_—“_The first man Adam became a living soul. The last man Adam became a life-giving spirit_”; _Rev. 22:14_—“_Blessed are they that wash their robes, that they may have the right to come to the tree of life._” The conclusions we have thus reached with regard to the incidents of man’s original state are combated upon two distinct grounds: 1st. The facts bearing upon man’s prehistoric condition point to a development from primitive savagery to civilization. Among these facts may be mentioned the succession of implements and weapons from stone to bronze and iron; the polyandry and communal marriage systems of the lowest tribes; the relics of barbarous customs still prevailing among the most civilized. For the theory of an originally savage condition of man, see Sir John Lubbock, Prehistoric Times, and Origin of Civilization: “The primitive condition of mankind was one of utter barbarism”; but especially L. H. Morgan, Ancient Society, who divides human progress into three great periods, the savage, the barbarian, and the civilized. Each of the two former has three states, as follows: I. Savage: 1. Lowest state, marked by attainment of speech and subsistence upon roots. 2. Middle state, marked by fish-food and fire. 3. Upper state, marked by use of the bow and hunting. II. Barbarian: 1. Lower state, marked by invention and use of pottery. 2. Middle state, marked by use of domestic animals, maize, and building stone. 3. Upper state, marked by invention and use of iron tools. III. Civilized man next appears, with the introduction of the phonetic alphabet and writing. J. S. Stuart-Glennie, Contemp. Rev., Dec. 1892:844, defines civilization as “enforced social organization, with written records, and hence intellectual development and social progress.” With regard to this view we remark:
