(3) A prosperous man, who sees some one else to be wretched, is tempted to pay no attention to it, alleging that it is no concern of his. Now, if this attitude were made a universal law of nature, the human race might subsist and even get on after a fashion; but it is impossible to will that such a principle should have the validity of a law of nature. Such a will would contradict itself, for many cases would occur in which the one willing would need the love and sympathy of others; he could not then without contradicting himself wish that selfish disregard should become a regular, a fixed uniformity. =The Social End is the Rational End.=--These illustrations make it clear that the "contradiction" Kant really depends upon to reveal the wrongness of acts, is the introduction of friction and disorder among the various concrete ends of the individual. He insists especially that the social relations of an act bring out its general purport. A right end is one which can be projected harmoniously into the widest and broadest survey of life which the individual can make. A "system of nature" or of conduct in which love of life should lead to its own destruction certainly contradicts itself. A course of action which should include all the tendencies that make for amusement and sluggishness would be inconsistent with a scheme of life which would take account of other tendencies--such as interest in science, in music, in friendship, in business achievement, which are just as real constituents of the individual, although perhaps not so strongly felt at the moment. A totally callous and cruel mode of procedure certainly "contradicts" a course of life in which every individual is so placed as to be dependent upon the sympathy and upon the help of others. It is the province of reason to call up a sufficiently wide view of the consequences of an intention as to enable us to realize such inconsistencies and contradictions if they exist; to put before us, not through any logical manipulation of the principle of contradiction, but through memory and imagination a particular act, proposal, or suggestion as a portion of a connected whole of life; to make real to us that no man, no act, and no satisfaction of any man, falls or stands to itself, but that it affects and is affected by others. Our conclusion is: the right as the _rational_ good means that which is harmonious with all the capacities and desires of the self, that which expands them into a coöperative whole.
