Unity in diversity

In this world we find that all happiness is followed by misery as its shadow. Life has its shadow, death. They must go together, because they are not contradictory, not two separate existences, but different manifestations of the same unit, life and death, sorrow and happiness, good and evil. The dualistic conception that good and evil are two separate entities, and that they are both going on eternally, is absurd on the face of it. 

They are the diverse manifestations of one and the same fact, one time appearing as bad, and at another time as good. The difference does not exist in kind, but only in degree. They differ from each other in degree of intensity. We find as a fact that the same nerve systems carry good and bad sensations alike, and when the nerves are injured, neither sensation comes to us. 

If a certain nerve is paralysed, we do not get the pleasurable feelings that used to come along the wire; and at the same time we do not get the painful feelings either. They are never two, but the same. Again, the same thing produces pleasure and pain at different times of life. The same phenomenon will produce pleasure in one, and pain in another. The eating of meat produces pleasure to a man, but pain to the animal which is eaten. 

There has never been anything which gives pleasure to all alike. Some are pleased, other displeased. So on it will go. Therefore, this duality of existence is denied. And what follows? I told you in my last lecture that we can never have ultimately everything good on this earth and nothing bad. It may have disappointed and frightened some of you, but I cannot help it, and I am open to conviction when I am shown to the contrary; but until that can be proved to me, and I can find that it is true, I cannot say so.

The general argument against my statement, and apparently a very convincing one, is this that in the course of evolution, all that is evil in what we see around us is gradually being eliminated, and the result is that if this elimination continues for millions of years, a time will come when all the evil will have been extirpated, and the good alone will remain. 

This is apparently a very sound argument. Would to God it were true! But there is a fallacy in it. and it is this that it takes for granted that both good and evil are things that are eternally fixed. It takes for granted that there is a definite mass of evil, which may be represented by a hundred, and likewise of good, and that this mass of evil is being diminished every day, leaving only the good. But is this so? 

The history of the world shows that evil is a continuously increasing quantity, as well as good. Take the lowest man; he lives in a forest. His sense of enjoyment is very small, and so also is his power to suffer. His misery is entirely on the sense-plane. If he does not get plenty of food, he is miserable; but give him plenty of food and freedom to rove and to hunt, and he is perfectly happy. 

His happiness consists only in the senses, and so does his misery also. But if that man increases in knowledge, his happiness will increase, the intellect will open to him, and his sense-enjoyment will evolve into intellectual enjoyment. He will feel pleasure in reading a beautiful poem, and a mathematical problem will be of absorbing interest to him. But, with these, the finer nerves will become more and more susceptible to miseries of mental pain, of which the savage does not think.
