ABSTRACT
This chapter explores what we see as a theoretical and philosophical challenge that confronts contemporary border studies, namely the complexity surrounding the definition of its very object of study–borders. The objective, therefore, of opening a dialogue has been accomplished on several fronts: between border studies and philosophy, and between border studies, philosophy and other disciplines engaged in border-related topics. The chapter outlines some intermingling and cross-cutting conceptual themes. It deals with geography, politics, economy, sociology, psychology, anthropology, aesthetics, ontology, ethics, language and nature. The general abandonment of the notion of the border as a strict line also has broad political consequences. The ontological approach is also taken up in direct relation to ethics.
