as a fulcrum for resisting decline, or producing recovery. In such a period despair wins control. The philosophy is pessimistic. The world is supposed to be coming to an end. Life is not valued. Ascetic practices fall in with the prevailing temper. Martyrdom has no great terrors; such as it has can be overcome by a little enthusiasm. Inroads of barbarians only add a little to the other woes, or hasten an end which is inevitable and is expected with resignation. At such a time a religion of demonism, other-worldliness, resignation, retirement from the world, and renunciation appeals both to those who want a dream of escape and to those who despair. Our own time, on the other hand, is one of advance on account of great unoccupied territories now opened at little or no cost to those who have nothing. Such a period is one of hope, power, and gain for the masses. Optimism is the philosophy. All the mores get their spirit from it. "Progress" is an object of faith. A philosophy of resignation and renunciation is unpopular. There is nothing which we cannot do, and will not do, if we choose. No mistake will cost much. It can be easily rectified. In the Renaissance in Italy, besides the rejection of religion and the disorder of the state, there was a great movement of new power derived from the knowledge which was changing the life conditions. Great social forces were set loose. Men of heroic dimensions, both in good and ill, appeared in great numbers. They had astounding ability to accomplish achievements, and appeared to be possessed by devils, so superhuman was their energy in vice and crime as well as in war, art, discovery, and literature. No doubt this phenomenon of heroic men belongs to an age of advance with a great upbursting of new power under more favorable conditions. It is to be noticed also that reproduction responds to conditions of advance or decline. In decline marriage and family become irksome. Celibacy arises in the mores. In times of advance sex vice and excess reach a degree, as in the Renaissance, which seems to constitute a social paroxysm. The sex passion rises to a frenzy to which everything else is sacrificed. The notion that mores grow either better or worse by virtue of some inherent tendency is to be rejected. Goodness or badness of the mores is always relative only. Their purpose is to serve needs, and their quality is to be defined by the degree to which they do it. We have noticed that there is in them a strain towards consistency, due to the fact that they are more efficient when consistent. They are consistent also in aberration and error when they fall under the dominion of any one of the false tendencies above described. Hence we may have the phenomena of degenerate mores characterizing a period; being a case of change in the mores not due to any external and determinable cause, and analogous either to vice or disease.
