Thus we may say that a permanent ideal is as necessary to the innovator as to the conservative; it is necessary whether we wish the king's orders to be promptly executed or whether we only wish the king to be promptly executed. The guillotine has many sins, but to do it justice there is nothing evolutionary about it. The favourite evolutionary argument finds its best answer in the axe. The Evolutionist says, "Where do you draw the line?" the Revolutionist answers, "I draw it _here_: exactly between your head and body." There must at any given moment be an abstract right and wrong if any blow is to be struck; there must be something eternal if there is to be anything sudden. Therefore for all intelligible human purposes, for altering things or for keeping things as they are, for founding a system for ever, as in China, or for altering it every month as in the early French Revolution, it is equally necessary that the vision should be a fixed vision. This is our first requirement. When I had written this down, I felt once again the presence of something else in the discussion: as a man hears a church bell above the sound of the street. Something seemed to be saying, "My ideal at least is fixed; for it was fixed before the foundations of the world. My vision of perfection assuredly cannot be altered; for it is called Eden. You may alter the place to which you are going; but you cannot alter the place from which you have come. To the orthodox there must always be a case for revolution; for in the hearts of men God has been put under the feet of Satan. In the upper world hell once rebelled against heaven. But in this world heaven is rebelling against hell. For the orthodox there can always be a revolution; for a revolution is a restoration. At any instant you may strike a blow for the perfection which no man has seen since Adam. No unchanging custom, no changing evolution can make the original good anything but good. Man may have had concubines as long as cows have had horns: still they are not a part of him if they are sinful. Men may have been under oppression ever since fish were under water; still they ought not to be, if oppression is sinful. The chain may seem as natural to the slave, or the paint to the harlot, as does the plume to the bird or the burrow to the fox; still they are not, if they are sinful. I lift my prehistoric legend to defy all your history. Your vision is not merely a fixture: it is a fact." I paused to note the new coincidence of Christianity: but I passed on.
