Mir'o Quesada’s quest for the supreme principle of reason

The goal of this paper is to outline and interpret Mir´o Quesada’s quest
for the supreme formal principle of theoretical and practical reason: the
principle of symmetry. The paper explains how this quest is rooted in
Kant’s philosophy, as well as how Mir´o Quesada would have arguably
reached the goal that escaped Kant himself. The paper also offers a new
formulation of symmetry in ethics: “Act in such a way that, if you demand another to behave in accordance to a norm N, you commit yourself
beforehand to behave in accordance to the conduct prescribed by norm N
in similar circumstances”. It also explains how the principle works. The
paper, finally, includes an explanation of the role of symmetry in law, as
well as the formalization of this in the language of logic.
