One question more: What is the goal? Nowadays it is asserted that man is infinitely progressing, forward and forward, and there is no goal of perfection to attain to. Ever approaching, never attaining, whatever that may mean and however wonderful it may be, it is absurd on the face of it. Is there any motion in a straight line? A straight line infinitely projected becomes a circle, it returns to the starting point. You must end where you begin, and as you began in God, you must go back to God. What remains? Detail work. Through eternity you have to do the detail work. Yet another question. Are we to discover new truths of religion as we go on? Yea and nay. In the first place we cannot know anything more of religion, it has all been known. In all the religions of the world you will find it claimed that there is a unity within us. Being one with divinity, there cannot be any further progress in that sense. Knowledge means finding this unity. I see you as men and women, and this is variety. It becomes scientific knowledge when I group you together and call you human beings. Take the science of chemistry, for instance. Chemists are seeking to resolve all known substances into their original elements and if possible to find the one element from which all these were derived. The time may come when they will find one element that is the source of all other elements. Reaching that, they can go no farther; the science of chemistry will have become perfect. So it is with the science of religion. If we can discover this perfect unity, there cannot be any farther progress. The next question is can such a unity be found? In India the attempt has been made from the earliest times to reach a science of religion and philosophy, for the Hindus do not separate these as is customary in Western countries. We regard religion and philosophy as but two aspects of one thing which must equally be grounded in reason and scientific truth. In the lectures that are to follow I shall try to explain to you first the system of the _Sânkhya_ philosophy, one of the most ancient in India, or in fact in the world. Its great exponent Kapila is the father of all Hindu psychology and the ancient system that he taught is still the foundation of all accepted systems of philosophy in India to-day,--which are known as the _Dârsanas_. They all adopt his psychology, however widely they differ in other respects. Next I shall endeavor to show you how Vedânta, as the logical outcome of the _Sânkhya_, pushes its conclusions yet farther. While its cosmology agrees with that taught by Kapila, the Vedânta is not satisfied to end in dualism, but continues its search for the final unity which is alike the goal of science and religion. To make clear the manner in which the task is accomplished will be the effort of the later lectures in this course. I THE SÂNKHYA COSMOLOGY
