=Classification of Enjoyments and Ethic.=--The once accepted comparative classification of enjoyments, according to which an inferior, higher, highest egoism may crave one or another enjoyment, now decides as to ethical status or unethical status. A lower enjoyment (for example, sensual pleasure) preferred to a more highly esteemed one (for example, health) rates as unethical, as does welfare preferred to freedom. The comparative classification of enjoyments is not, however, alike or the same at all periods; when anyone demands satisfaction of the law, he is, from the point of view of an earlier civilization, moral, from that of the present, non-moral. "Unethical" indicates, therefore, that a man is not sufficiently sensible to the higher, finer impulses which the present civilization has brought with it, or is not sensible to them at all; it indicates backwardness, but only from the point of view of the contemporary degree of distinction.--The comparative classification of enjoyments itself is not determined according to absolute ethics; but after each new ethical adjustment, it is then decided whether conduct be ethical or the reverse. 43 =Inhuman Men as Survivals.=--Men who are now inhuman must serve us as surviving specimens of earlier civilizations. The mountain height of humanity here reveals its lower formations, which might otherwise remain hidden from view. There are surviving specimens of humanity whose brains through the vicissitudes of heredity, have escaped proper development. They show us what we all were and thus appal us; but they are as little responsible on this account as is a piece of granite for being granite. In our own brains there must be courses and windings corresponding to such characters, just as in the forms of some human organs there survive traces of fishhood. But these courses and windings are no longer the bed in which flows the stream of our feeling. 44 =Gratitude and Revenge.=--The reason the powerful man is grateful is this. His benefactor has, through his benefaction, invaded the domain of the powerful man and established himself on an equal footing: the powerful man in turn invades the domain of the benefactor and gets satisfaction through the act of gratitude. It is a mild form of revenge. By not obtaining the satisfaction of gratitude the powerful would have shown himself powerless and have ranked as such thenceforward. Hence every society of the good, that is to say, of the powerful originally, places gratitude among the first of duties.--Swift has added the dictum that man is grateful in the same degree that he is revengeful. 45
