If the heap of things demanded proved on inspection less chaotic than at first they seemed, if they furnished their own relative test and measure, then the casuistic problem would be solved. If it were found that all goods quâ goods contained a common essence, then the amount of this essence involved in any one good would show its rank in the scale of goodness, and order could be quickly made; for this essence would be the good upon which all thinkers were agreed, the relatively objective and universal good that the philosopher seeks. Even his own private ideals would be measured by their share of it, and find their rightful place among the rest.
Various essences of good have thus been found and proposed as bases of the ethical system. Thus, to be a mean between two extremes; to be recognized by a special intuitive faculty; to make the agent happy for the moment; to make others as well as him happy in the long run; to add to his perfection or dignity; to harm no one; to follow from reason or flow from universal law; to be in accordance with the will of God; to promote the survival of the human species on this planet,—are so many tests, each of which has been maintained by somebody to constitute the essence of all good things or actions so far as they are good.
No one of the measures that have been actually proposed has, however, given general satisfaction. Some are obviously not universally present in all cases,—e.g., the character of harming no one, or that of following a universal law; for the best course is often cruel; and many acts are reckoned good on the sole condition that they be exceptions, and serve not as examples of a universal law.
