Thus, if he is deceived, he will be self-deceived and the author is blameless. _Three Theories of Life._ Only three noteworthy theories have been offered as solutions to the riddle of existence and in order that the reader may be able to make the important choice between them, we will state briefly what they are and give some of the arguments which lead us to advocate the doctrine of Rebirth as the method which favors soul-growth and the ultimate attainment of perfection, thus offering the best solution to the problem of life. 1) THE MATERIALISTIC THEORY _teaches that life is but a short journey from the cradle to the grave, that there is no higher intelligence in the universe than man; that his mind is produced by certain correlations of matter and that therefore death, and dissolution of the body terminate existence._ There was a day when the arguments of Materialistic philosophers seemed convincing, but as science advances it discovers more and more that there is a spiritual side to the universe. That life and consciousness may exist without being able to give us a sign, has been amply proven in the cases where a person who was entranced and thought dead for days has suddenly awakened and told all that had taken place around the body. Such eminent scientists as Sir Oliver Lodge, Camille Flammarion, Lombroso and other men of highest intelligence and scientific training, have unequivocally stated as the result of their investigations, that the intelligence which we call man survives death of the body and lives on in our midst as independently of whether we see them or not as light and color exist all about the blind man regardless of the fact that he does not perceive them. These scientists have reached their conclusion after years of careful investigation. They have found that the so-called dead can, and under certain circumstances do, communicate with us in such a manner that mistake is out of the question. We maintain that their testimony is worth more than the argument of materialism to the contrary, for it is based upon years of careful investigation, it is in harmony with such well established laws as _the law of conservation of matter_ and _the law of conservation of energy_. Mind is a form of energy, and immune from destruction as claimed by the materialist. Therefore we disbar the materialistic theory as unsound, because out of harmony with the laws of nature and with well established facts. 2) THE THEORY OF THEOLOGY _claims that just prior to each birth a soul is created by God and enters into the world where it lives for a time varying from a few minutes to a few score of years; that at the end of this short span of life it returns through the portal of death to the invisible beyond, where it remains forever in a condition of happiness or misery according to the deeds done in the body during the few years it lived here_.
