There has probably never been a period in the history of thought entirely resembling the present. Thinkers everywhere are conscious of two things, first, that the region of mystery has never before been so clearly defined, and secondly, that that region can be entered more easily than has hitherto been the case; it may, therefore, perhaps be induced to render up some of its secrets if investigators of all schools pursue their search with determination. The problems with which we are faced, as we study the known facts of life and existence, are susceptible of clearer de finition than heretofore, and though we do not know the answer to our questions, though we have not as yet dis covered the solution to our problems, though no panacea lies ready to our hand whereby we can remedy the world's ills, yet the very fact that we can define them, that we can point in the direction in which mystery lies, and that the light of science, of religion, and of philosophy, has been shed upon vast tracts which were earlier considered lands of darkness, is a guarantee of success in the future. We know so much more than was the case five hundred years ago, except in a few circles of wise men and mystics; we have discovered so many laws of nature, even though as yet we cannot apply them, and the knowledge of things as they are (and I choose these words very deliberately) has made immense strides. 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 ap parent 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.
