Thus is the old ground of scientific materialism being deserted by all progressive scientists. While we do not yet know a great deal about life, science has gone far enough to permit a grasp of facts and principles from which conclusions may be logically drawn and working hypotheses constructed. Sir Oliver Lodge, who is president of one of the great English Universities, and ranks as one of the world's most eminent scientists, speaking of his conception of life, says that "It is dependent on matter for its phenomenal appearance--for its manifestation to us here and now, and for all its terrestrial activities; but otherwise I conceive that it is independent, that its essential existence is continuous and permanent, though its interactions with matter are discontinuous and temporary; and I conjecture that it is subject to a law of evolution--that a linear advance is open to it--whether it be in its phenomenal or in its occult state."[J] Later in the same work he expresses the opinion "that life is something outside the scheme of mechanics--outside the categories of matter and energy; though it can nevertheless control and direct material forces...." In closing his volume on _Life and Matter_ this distinguished scientist says: "What is certain is that life possesses the power of vitalizing the complex material aggregates which exist on this planet, and of utilizing their energies for a time to display itself amid terrestrial surroundings; and then it seems to disappear or evaporate whence it came. It is perpetually arriving and perpetually disappearing. While it is here, if it is at a sufficiently high level, the animated material body moves about and strives after many objects, some worthy, some unworthy; it acquires thereby a certain individuality, a certain character. It may realize itself, moreover, becoming conscious of its own mental and spiritual existence; and it then begins to explore the Mind which, like its own, it conceives must underlie the material fabric--half displayed, half concealed, by the environment, and intelligible only to a kindred spirit. Thus the scheme of law and order dimly dawns on the nascent soul, and it begins to form clear conceptions of truth, goodness, and beauty; it may achieve something of permanent value, or a work of art or of literature; it may enter the region of emotion and may evolve ideas of the loftiest kind; it may degrade itself below the beasts, or it may soar till it is almost divine.
