Some of the modern scientists who hold the monistic position have found out the same truth which was discovered long ago by the Vedantic philosophers in India. J. Arthur Thomson, an eminent English scientist of the present day, in his book on "The Study of Animal Life," says: "The world is one, not two-fold-, the spiritual influx is the primal reality and there is nothing in the end which was not also in the beginning." But the evolutionists do not accept this truth. Let us understand it clearly. It means that that which existed potentially at the time of the beginning of evolution has gradually manifested in the various stages and grades of evolution. If we admit that a unicellular germ of life or a bioplasm, after passing through various stages of evolution, has ultimately manifested in the form of a highly developed human being, then we shall have to admit the potentiality of all the manifested powers in that germ or bioplasm, because the law is "that which exists in the end existed also in the beginning." The animal nature, higher nature, mind, intellect, spirit, all these exist potentially in the germ of life. If we do not admit this law then the problem will arise: How can non-existence become existent? How can something come out of nothing? How can that come into existence which did not exist before? Each germ of life, according to Vedanta, possesses infinite potentialities and infinite possibilities. The powers that remain latent have the natural tendency to manifest perfectly and to become actual. In their attempt they vary according to the surrounding environments, selecting suitable conditions or remaining latent as long as circumstances do not favor them. Therefore variation, according to Vedanta, is caused by this attempt of the potential powers to become actual. When life and mind began to evolve, the possibilities of action and reaction hitherto latent in the germ of life became real and all things became, in a sense, new. Nobody can imagine the amount of latent power which a minute germ of life possesses until it expresses in gross form on the physical plane. By seeing the seed of a Banyan tree, one who has never seen the tree cannot imagine what powers lie dormant in it. When a baby is born we cannot tell whether he will be a great saint, or a wonderful artist, or a philosopher, or an idiot, or a villain of the worst type. Parents know nothing about his future. Along with his growth certain latent powers gradually begin to manifest. Those which are the strongest and most powerful will overcome others and check their course for some time; but when the powers that remain subdued by stronger ones get favorable conditions they will appear in manifested forms. As, for instance, chemical forces may slumber in matter for a thousand years, but when the contact with the re-agents sets them free, they appear again and produce certain results. For thousands of years galvanism slumbered in copper and zinc, which lay quietly beside silver. As soon as all three are brought together under the required conditions silver is consumed in flame. A dry seed of a plant may preserve the slumbering power of growth through two or three thousand years and then reappear under favorable conditions. Sir G. Wilkinson, the great archaeologist, found some grains of wheat in a hermetically sealed vase in a grave at Thebes, which must have lain there for three thousand years. When Mr. Pettigrew sowed them they grew into plants. Some vegetable roots found in the hands of an Egyptian mummy, which must have been at least two thousand years old, were planted in a flower-pot, and they grew and flourished. Thus, whenever the latent powers get favorable conditions, they manifest according to their nature, even after thousands of years.
