Nevertheless, the mystery land still remains to be opened up, and our problems are still numerous. There is the problem of our own particular life, whatever that may be; there is the problem of that which is largely termed the "Not-Self", and which concerns our physical body, our environment, our circumstances, and our life conditions; if we are of an introspective turn of mind, there is the problem of our particular set of emotions, and of the thoughts, desires, and instincts by which we control action. Group problems are many; why should there be suffering, starvation, and pain? Why should the world as a whole be in the thrall of the direst poverty, of sickness, of discomfort? What is the purpose underlying all that we see around us, and what will be the outcome of world affairs, viewing them as a whole? What is the destiny of the human race, what is its origin, and what is the key to its present condition? Is there more than this one life, and is the sole interest to be found in that which is apparent and material? Such queries pass through all our minds at various times, and have passed through the minds of thinkers right down through the centuries.
There have been many attempts to reply to these questions, and as we study them, we find that the answers given fall into three main groups, and that three principal solutions are held out for the consideration of men. These three solutions are:— First, Realism. Another name for this school is that of Materialism. It teaches that "the presentation which we have in consciousness of an external world is true"; that things are what they seem; that matter and force, as we know them, are the only reality, and that it is not possible for man to get beyond the tangible. He should be satisfied with facts as he knows them, or as science tells him they are. This is a perfectly legitimate method of solution, but for some of us it fails in that it does not go far enough. In refusing to concern itself with anything except that which can be proven and demonstrated it stops short at the very point where the enquirer says, "that is so, but why?" It leaves out of its calculation much that is known and realised as truth by the average man, even though he may be unable to explain why he knows it to be true. Men everywhere are recognising the accuracy of the facts of the realistic school, and of material science, yet at the same time they feel innately that there is, underlying the proven objective manifestation, some vitalising force, and some coherent purpose which cannot be accounted for in terms of matter alone.
