This paper explores the “philosophy of the philosophy of law,” addressing the need to redefine legal philosophy as a distinct philosophical discipline, not merely legal theory or science. It emphasizes that any reflection on the nature and justification of legal philosophy is itself philosophical. Using Gustavo Bueno’s framework, the author proposes a typology of legal-philosophical discourse, identifying four genres: (a) fundamental/dogmatic philosophy, which applies universal principles to law; (b) centered/genitive philosophy, developed strictly within legal boundaries; (c) adjective philosophy, blending indistinctly with legal science; and (d) critical philosophy, a second-order reflection on legal ideas. The paper argues that legal philosophy’s self-referential nature sets it apart from scientific disciplines and makes its conceptual foundation a central philosophical challenge.
