H. H. Bawden has reviewed Prof. Loeb’s work in the Psychological Review, Jan. 1900. Janósik has found segmentation in the unfertilized eggs of mammalians. Prof. Loeb considers it possible that only the ions of the blood prevent the parthenogenetic origin of embryos in mammals, and thinks it not improbable that by a transitory change in these ions it will be possible to produce complete parthenogenesis in these higher types. Dr. Bawden goes on to say that “both parent and child are dependent upon a common source of energy. The universe is one great organism, and there is no inorganic or non-organic matter, but differences only in degrees of organization. Sex is designed only secondarily for the perpetuation of species; primarily it is the bond or medium for the connection and interaction of the various parts of this great organism, for maintaining that degree of heterogeneity which is the prerequisite of a high degree of organization. By means of the growth of a lifetime I have become an essential part in a great organic system. What I call my individual personality represents simply the focusing, the flowering of the universe at one finite concrete point or centre. Must not then my personality continue as long as that universal system continues? And is immortality conceivable if the soul is something shut up within itself, unshareable and unique? Are not the many foci mutually interdependent, instead of mutually exclusive? We must not then conceive of an immortality which means the continued existence of an individual cut off from that social context which is really essential to his very nature.”
