Based on various conflicts of evaluation (bullfight, contemporary art), this study of the relationship between aesthetic experience and animality evidences the existence of value registers, above the very values such as beauty or sensitiveness. Aesthetic register is used by the supporters of a work in the name of cultural traditions or artistic quality, while ethical register is used by its opponents in the name of respect for living beings or of refusal to inflict sufferings. Whereas value conflicts allow discussions that may end up with an agreement, value registers conflicts can generate but endless fights, since the arguments of one party are without any relevance for the other party. Out of various case studies, mostly in France and in the USA, two questions arise. First, what kinds of moral and/or aesthetic boundaries are transgressed by the use of animals “living or even dead” in artistic proposals? Second, how do these transgressions change according to different cultures? Do they raise more difficulties in western culture than in Chinese or Asian culture, since the latter provides the propositions which have been most violently attacked in the Western world?
