  Sixth and finally, in the brief “Appendix on the methodology of taste,” Kant suggests that the cultivation or realization of common standards of taste in a society can be conducive to the discovery of the more general “art of the reciprocal communication of the ideas of the most educated part” of a society “with the cruder, the coordination of the breadth and refinement of the former with the natural simplicity and originality of the latter” (CPJ, §60, 5:356), where this art is apparently necessary to the realization of the goal of “lawful sociability,” or the establishment of a stable polity on the basis of principles of justice rather than sheer force. Thus, aesthetic experience can be conducive to the development of sound politics as well as personal ethics, although the two are of course not unconnected, since Kant is a political moralist who believes that we have a moral duty to establish a just state, not merely a prudential interest in doing so.
