Let me say at the very outset, that there is a common view to-day among many thoughtful, among many good men, that it does not much matter what a man believes providing that his conduct is right. That is a half truth, not a whole truth, and it is the natural reaction from the Middle Age view in Europe that it did not matter what a man’s conduct was provided that his beliefs were orthodox. Such a view has not only been found in mediæval Europe, but also has been found in India herself. You will find among Indians to-day, as still among some Christians, that the all-important matter is belief in certain dogmas, and that where those are held conduct is comparatively unimportant. We all know men in all faiths who are orthodox, as it is said, in belief, but whose lives are worldly lives, and sometimes not even of a very high worldly character. Now, a century or so ago that view was so common that men were persecuted, men were penalised, because of a difference of theological views. If men did not believe, at one stage, the dogmas of the Roman Catholic Church in Europe, then their fate was, at first, the stake, then later the prison, and still later, slander, social ostracism, and disabilities under the law of the land. In England, that is now largely swept aside, and we have the opposite exaggeration: “Let a man think as he will; but let him be a good citizen, a good man.” But that leaves out the profound truth that “man is created by thought, and as a man thinks, so he is”; conduct is not independent of thought, for thought is the spring of conduct, and so it is written in the _Bhagavaḍ-Gīṭā_, that “a man is compacted, composed, of his beliefs,” and as a man believes, so he is. You have to make, however, a distinction between beliefs conventionally accepted, and the real belief, which is the conviction of the heart, out of which action arises. And so, I urge on you to-day that right-thinking on the great truths of life is a most important part of the whole of your conduct. The better your thought, the better will be your life. The truer your thought, the more candid and transparent will be your actions. But _remember that it must be your own thought_, and not the thought of your neighbour, not the thought of authority, not the thought of a book, however ancient and however sacred, not the thought of a great man, however true for him; the thought that moulds conduct is the thought of the actor, and every man is responsible for his own thinking; the repetition of the thought of another is useless and even mischievous. Be not then afraid to think, even about God Himself. Do not think it is blasphemous to enquire; do not think it is blasphemous to doubt. Doubt is the stage which comes before a larger and truer thinking. You doubt your past thought, because you are opening up new vistas of thought and the past is lying behind you. The man who never doubts never really thinks; and there is a wholesome, a healthy scepticism which is the forerunner of a nobler and a truer faith. Think as far as you can. It is true that from the very Highest thought and speech fall back unable to go farther; but as far as you can think, as far as your intellect is able to grasp, to investigate, to argue, think your freest and your noblest, and you will grow by your errors as well as by your truths. Do not then fear to think; do not fear to be called unorthodox; try your best to think truly and accurately, and trust in Truth, who never betrays her servant. The determination to think your highest, the determination to think your best, may lead you into some desert for a time, but there are gardens on the other side of the desert. You may have to cross many a desert, many a torrent which seems to sweep you away; but I, who ventured all to seek for Truth, who left family, friends, religion, because their religion had become to me untrue, I bear you witness that such unbelief is the way to a higher, a greater, and a serener faith, and that those who are unwilling to lose the life of the past will not be able to advance into the life of the future.
