We are always making this mistake in judging others; we are always inclined to think that our little mental universe is all that is; our ethics, our morality, our sense of duty, our sense of utility, are the only things that are worth having. The other day when I was going to Europe, I was passing through Marseilles, where a bull-fight was being held. All the Englishmen in the steamer were mad with excitement, abusing and criticising the whole thing as cruel. When I reached England, I heard of a party of prize-fighters who had been to Paris, and were kicked out unceremoniously by the French, who thought prize-fighting very brutal. When I hear these things in various countries, I begin to understand the marvellous saying of Christ: “Judge not that ye be not judged.” The more we learn, the more he find out how ignorant we are, how multiform and multi-sided is this mind of man. When I was a boy, I used to criticise the ascetic practices of my countrymen; great preachers in our own land have criticised them; the greatest man that was ever born, Buddha himself, criticised them. But all the same, as I am growing older, I feel that I have no right to judge. Sometimes I wish that, in spite of all their incongruities, I had one fragment of their power to do and suffer. Often I think that my judgment and my criticism do not proceed from any dislike of torture, but from sheer cowardice — because I cannot do it — I dare not do it.
It is the fashion of the day. Ninety-nine per cent of what we call scientific knowledge is mere theories. And many of them are no better than the old superstitions of ghosts with many heads and hands, but with this difference that the latter differentiated man a little from stocks and stones. True science asks us to be cautious. Just as we should be careful with the priests, so we should be with the scientists. Begin with disbelief. Analyse, test, prove everything, and then take it. Some of the most current beliefs of modern science have not been proved. Even in such a science as mathematics, the vast majority of its theories are only working hypotheses. With the advent of greater knowledge they will be thrown away.
