Both Belloc and Krutch, it will be observed, agree that the world has changed--that is, that the popular idea as to what life really is, has changed. They differ only as to the sentiment with which the mass of the population are supposed to regard the alterations which have taken place in the view. Belloc, who is a Catholic, believes that Protestants at least are quite satisfied to have lost the world of “poetry, mythology and religion”; have in fact “allowed it to slip away unnoticed.” Krutch, the radical editor, suggests that there has been a struggle, that science has forced man to give up the world as he would like to have it and to accept the world as he has gradually come to discover it--not by making the lost world undesirable, but by making it seem ridiculous and without actuality. Krutch, I think, is right, in so far as the vast majority are concerned. They have resisted, Protestants as well as Catholics, and many who are neither Catholic nor Protestant but merely lovers of tradition and of the classic ideal of austere dignity and of the romantic ideal of a world well lost for love. They have struggled. They still struggle. But there is an ever increasing demand from some quarters that the struggle be given up in despair. Now if science indeed represents the world as man gradually comes to discover it--that is, if science represents the world as it is; and if the testimony of scientists as to the nature of this reality be fairly uniform and uncontradictory, with a growing unanimity promising to bring an eventual unison out of such discords as may still exist, then the only thing for the sensible citizen to do is to let the dead past bury its dead, turn from the grave with as little moaning as possible, and adapt himself with all speed to changed conditions. The advice, “Do it now!” is being hurled at him. Why should he not heed it? Nobody wants to be a mere reactionary, still less to live in a fool’s paradise. But does science represent the world as the world really is? Can we say that there is any likelihood of the scientific picture being more photographically perfect than is, or was, the romantic picture? Are scientists in agreement, so that there is little or no choice or opinion offered? Are their theories themselves logically consistent? What, precisely, is science? And finally, have its findings been faithfully reported to us?
