When we consider that this invisible fleck bears in its cell or cells the impress of every condition bearing on its progenitors from remotest time, and will express it in all these conditions, it is no longer a phenomenon on which we gaze, but a miracle of creative power, and all that has been written by physiologists since Galen’s time as to its cause is as children’s prattle. The material side furnishes no adequate explanation. Its coarse methods are not adapted to measure the illusive psyche. The balance weighs not, the scalpel dissects not, the retort holds not the elements of the soul. Scientific Methods of the Study of Man, and Results. THE EVOLUTIONIST.--Scientists have different ways of studying man. The evolutionist first develops the form. He says that life began in protoplasm in the unrecorded ages of the past, and step by step, through mollusk, fish, saurian and mammal, has arisen by the “struggle for existence” and “survival of the fittest,” until the mammal by strangely fortuitous chances has become a human being. As the human body is a modified animal form, so the intellect is a modified and developed instinct, the highest and most spiritual conscientiousness being only the result of accumulated experiences of what is for the best. The highest of animals is man, with no barrier between him and them, and subject to the same fate. There is no indication of a guiding intelligence, and if he possess an immortal spirit, so does the mollusk and the fleck of protoplasm.
