In a small work entitled _A Theory of Life deduced from the Evolution Philosophy_ a few thoughts are recorded by _Sylvan Drey_ relative to the manner in which, from central doctrines identical with the teachings of Herbert Spencer, a system of religion, an ideal society, a theory of ethics, and a political creed--the doctrine of social individualism--may be built up. The religion is to recognize an inexplicable and inconceivable energy revealing itself in the universe, of which the highest theistic conception possible to human beings, free from the supposition that it represents a likeness, is the only one that can be accepted. "Absolute truth is beyond the grasp of human beings; but for all practical purposes the teachings of the evolution philosophy, relative truths though they may be, may be regarded as final and conclusive." Mr. Drey's paper of thirty-four pages is published by Williams & Norgate, London. FOOTNOTES: [61] The American Woods. Exhibited by Actual Specimens. Part I, representing Twenty-five Species.
