The discussion about substance and qualities is very old, and you will sometimes find that the old superstition lives even at the present day. Most of you have read how, during the Middle Ages, and, I am sorry to say, even much later, this was one of the subjects of discussion, whether qualities adhered to substance, whether length, breadth, and thickness adhered to the substance which we call dead matter, whether, the substance remaining, the qualities are there or not. To this our Buddhist says, “You have no ground for maintaining the existence of such a substance; the qualities are all that exist; you do not see beyond them.” This is just the position of most of our modern agnostics. For it is this fight of the substance and qualities that, on a higher plane, takes the form of the fight between noumenon and phenomenon. There is the phenomenal world, the universe of continuous change, and there is something behind which does not change; and this duality of existence, noumenon and phenomenon, some hold, is true, and others with better reason claim that you have no right to admit the two, for what we see, feel, and think is only the phenomenon. You have no right to assert there is anything beyond phenomenon; and there is no answer to this. The only answer we get is from the monistic theory of the Vedanta. It is true that only one exists, and that one is either phenomenon or noumenon. It is not true that there are two — something changing, and, in and through that, something which does not change; but it is the one and the same thing which appears as changing, and which is in reality unchangeable. We have come to think of the body, and mind, and soul as many, but really there is only one; and that one is appearing in all these various forms. Take the well-known illustration of the monists, the rope appearing as the snake. Some people, in the dark or through some other cause, mistake the rope for the snake, but when knowledge comes, the snake vanishes and it is found to be a rope. By this illustration we see that when the snake exists in the mind, the rope has vanished, and when the rope exists, the snake has gone. When we see phenomenon, and phenomenon only, around us, the noumenon has vanished, but when we see the noumenon, the unchangeable, it naturally follows that the phenomenon has vanished. Now, we understand better the position of both the realist and the idealist. The realist sees the phenomenon only, and the idealist looks to the noumenon. For the idealist, the really genuine idealist, who has truly arrived at the power of perception, whereby he can get away from all ideas of change, for him the changeful universe has vanished, and he has the right to say it is all delusion, there is no change. The realist at the same time looks at the changeful. For him the unchangeable has vanished, and he has a right to say this is all real.
What is the outcome of this philosophy? It is that the idea of Personal God is not sufficient. We have to get to something higher, to the Impersonal idea. It is the only logical step that we can take. Not that the personal idea would be destroyed by that, not that we supply proof that the Personal God does not exist, but we must go to the Impersonal for the explanation of the personal, for the Impersonal is a much higher generalization than the personal. The Impersonal only can be Infinite, the personal is limited. Thus we preserve the personal and do not destroy it. Often the doubt comes to us that if we arrive at the idea of the Impersonal God, the personal will be destroyed, if we arrive at the idea of the Impersonal man, the personal will be lost. But the Vedantic idea is not the destruction of the individual, but its real preservation. We cannot prove the individual by any other means but by referring to the universal, by proving that this individual is really the universal. If we think of the individual as separate from everything else in the universe, it cannot stand a minute. Such a thing never existed.
Secondly, by the application of the second principle, that the explanation of everything must come out of the nature of the thing, we are led to a still bolder idea, and one more difficult to understand. It is nothing less than this, that the Impersonal Being, our highest generalization, is in ourselves, and we are That. “O Shvetaketu, thou art That.” You are that Impersonal Being; that God for whom you have been searching all over the universe is all the time yourself — yourself not in the personal sense but in the Impersonal. The man we know now, the manifested, is personalised, but the reality of this is the Impersonal. To understand the personal we have to refer it to the Impersonal, the particular must be referred to the general, and that Impersonal is the Truth, the Self of man.
There will be various questions in connection with this, and I shall try to answer them as we go on. Many difficulties will arise, but first let us clearly understand the position of monism. As manifested beings we appear to be separate, but our reality is one, and the less we think of ourselves as separate from that One, the better for us. The more we think of ourselves as separate from the Whole, the more miserable we become. From this monistic principle we get at the basis of ethics, and I venture to say that we cannot get any ethics from anywhere else. We know that the oldest idea of ethics was the will of some particular being or beings, but few are ready to accept that now, because it would be only a partial generalization. The Hindus say we must not do this or that because the Vedas say so, but the Christian is not going to obey the authority of the Vedas. The Christian says you must do this and not do that because the Bible says so. That will not be binding on those who do not believe in the Bible. But we must have a theory which is large enough to take in all these various grounds. Just as there are millions of people who are ready to believe in a Personal Creator, there have also been thousands of the brightest minds in this world who felt that such ideas were not sufficient for them, and wanted something higher, and wherever religion was not broad enough to include all these minds, the result was that the brightest minds in society were always outside of religion; and never was this so marked as at the present time, especially in Europe.
To include these minds, therefore, religion must become broad enough. Everything it claims must be judged from the standpoint of reason. Why religions should claim that they are not bound to abide by the standpoint of reason, no one knows. If one does not take the standard of reason, there cannot be any true judgment, even in the case of religions. One religion may ordain something very hideous. For instance, the Mohammedan religion allows Mohammedans to kill all who are not of their religion. It is clearly stated in the Koran, “Kill the infidels if they do not become Mohammedans.” They must be put to fire and sword. Now if we tell a Mohammedan that this is wrong, he will naturally ask, “How do you know that? How do you know it is not good? My book says it is.” If you say your book is older, there will come the Buddhist, and say, my book is much older still. Then will come the Hindu, and say, my books are the oldest of all. Therefore referring to books will not do. Where is the standard by which you can compare? You will say, look at the Sermon on the Mount, and the Mohammedan will reply, look at the Ethics of the Koran. The Mohammedan will say, who is the arbiter as to which is the better of the two? Neither the New Testament nor the Koran can be the arbiter in a quarrel between them. There must be some independent authority, and that cannot be any book, but something which is universal; and what is more universal than reason? It has been said that reason is not strong enough; it does not always help us to get at the Truth; many times it makes mistakes, and, therefore, the conclusion is that we must believe in the authority of a church! That was said to me by a Roman Catholic, but I could not see the logic of it. On the other hand I should say, if reason be so weak, a body of priests would be weaker, and I am not going to accept their verdict, but I will abide by my reason, because with all its weakness there is some chance of my getting at truth through it; while, by the other means, there is no such hope at all.
We should, therefore, follow reason and also sympathise with those who do not come to any sort of belief, following reason. For it is better that mankind should become atheist by following reason than blindly believe in two hundred millions of gods on the authority of anybody. What we want is progress, development, realisation. No theories ever made men higher. No amount of books can help us to become purer. The only power is in realisation, and that lies in ourselves and comes from thinking. Let men think. A clod of earth never thinks; but it remains only a lump of earth. The glory of man is that he is a thinking being. It is the nature of man to think and therein he differs from animals. I believe in reason and follow reason having seen enough of the evils of authority, for I was born in a country where they have gone to the extreme of authority.
The Hindus believe that creation has come out of the Vedas. How do you know there is a cow? Because the word cow is in the Vedas. How do you know there is a man outside? Because the
