classes, nations, times, or circumstances, which has any practical value, and it is so much more practical the more defined, exact, precise and the less general it is. The most universal and most widely recognized right or need is in its quality no more rightful, better, or valuable than the most insignificant right of the moment, than the momentary need of some individual. Although we know that the sun is hundreds of thousands of miles in diameter, we are nevertheless free to see it no larger than a plate. And though we may acknowledge that some moral law is theoretically or universally good or holy, we are free in practice to reject it momentarily, in parts, or individually, as bad and useless. Even the most sacred right of the most universal extent is valid only within certain definite limits, and within particular limits an otherwise very great wrong may be a valid right. It is true that there is an eternal difference between assumed and true interests, between passion and reason, between essential, predominating, general, well-founded needs and inclinations, and accidental, subordinate, special appetites. But this difference is not one of two separated worlds, a world of the good and a world of the bad. It is not a positive, general, continuous, absolute difference, but merely a relative one. Like the difference between beautiful and homely, it depends on the individuality of the person who distinguishes. That which is a true and fundamental need in one case, is a secondary, subordinate, and wrong desire in another. _Morality is the aggregate of the most contradictory ethical laws which serve the common purpose of regulating the conduct of man toward himself and others in such a way that the future is considered as well as the present, the one as well as the other, the individual as well as the genus. The individual man finds himself lacking, inadequate, limited in many ways. He requires for his complement other people, society, and must therefore live and let live. The mutual concessions which arise out of these relative needs are called morality._
