The general sense or norm that is opposed to mere temperament and impulse may rest upon the ethos of a particular time and country--the traditional habits and customs that the Rousseauist is wont to dismiss as “artificial”--or it may rest in varying degrees upon immediate perception. For example, the Ismene and Antigone of Sophocles are both ethical; but Ismene would abide by the law of the state, whereas Antigone opposes to this law something still more universal--the “unwritten laws of heaven.” This insight of Antigone into a moral order that is set not only above her ordinary self but above the convention of her time and country is something very immediate, something achieved, as I shall try to show more fully later, with the aid of the imagination. It is scarcely necessary to add that such a perfect example of the ethical imagination as one finds in Antigone--the imagination that works concentric with the human law--is rare. In actual life for one Antigone who obeys the “unwritten laws of heaven” there will be a thousand Ismenes who will be guided in their moral choices by the law of the community. This law, the convention of a particular place and time, is always but a very imperfect image, a mere shadow indeed of the unwritten law which being above the ordinary rational level is, in a sense to be explained later, infinite and incapable of final formulation. And yet men are forced if only on practical grounds to work out some approximation to this law as a barrier to the unchained appetites of the individual. The elements that enter into any particular attempt to circumscribe the individual in the interests of the community are very mixed and in no small measure relative. Yet the things that any group of men have come together about--their conventions in the literal meaning of the word--even the tabus of a savage tribe, are sure to reflect, however inadequately, the element of oneness in man, the element which is opposed to expansive impulse, and which is no less real, no less a matter of immediate experience, than the element of irreducible difference. The general sense therefore should never be sacrificed lightly to the sense of the individual. Tabu, however inferior it may be to insight, deserves to rank higher after all than mere temperament.[41]
