The temporal and moral chaos, so uniformly evident in the world today, gives clear and undeniable proof of the necessity of moral standards external to, and therefore independent of, the caprice of man. This chaos, of which only the material results are brought home to us with adequate reality, is the direct and unavoidable result of the acceptance of the theory that man is capable of legislating for himself in the moral sphere. Indeed, the deepest of truths is expressed in the oft-quoted statement that the most cogent proof of the divine origin of and the necessity of mankind for the ten commandments is given by the results which follow their being cast aside. In like manner some external, ultimate and unchangeable standards are necessary in the fields of economics and politics, sciences which of their essence have reference to man in relation to his fellows and to the physical world. These must be ultimate and unchangeable because, in his physical nature, man has unchanging fundamental needs; external, because it is by its success or failure in satisfying these very needs and not those invented by the fickle desires of the individual that any political or economic system must be judged. By what standards are we to measure such a system, what gauge are we to apply to its propositions in order that our appreciation of it may be true and our judgment just?
