Abstract
This article tries to study the evolution of the place and significance of the term “fiction” in Bentham’s critical strategy against English law. If, in an initial phase, Bentham uses fictions to bring to light mystification operating in English law, he then attacks the theories that sought to justify and ground political society and law. Bentham proposes a foundation justified with the help of the principle of utility, which he presents as a “fundamental axiom” that needs no proof. Paradoxically, his argumentation, taken as a whole, becomes intrinsically problematical on recognizing the inevitable linguistic necessity of fictions and the fictitious character of utility: every legal discourse will, in consequence, invoke the fictions that it previously criticised. He must therefore refine his theory of fictions and construct its positivity with the aim of drawing up a legal discourse that satisfies the demands of his theory of law
