This article, consisting of four parts, is a philosophical analysis of positive law applied to animals. After putting the law to the test of philosophical astonishment and drawing up an inventory of animal conditions made lawful by law, the author questions the links between the "proper of man" and the rights of animals. These clarifications address the question of who can be a subject of law from a legal point of view. Finally, in the fourth part, the author wonders about the fictional status of the law and shows that the obstacles to confer rights on animals are not technical but ideological.
