and our access to the world.

The current Issue of the Revista Portuguesa de Filosofia deals with a number of subjects that revolve around determining the role that perception and concepts perform in the constitution of our access to the world and, consequently, the knowledge we acquire about it. The thematic focus of this Issue is, thus, the consideration of the proper status of perceptions, concepts and relationships that subsist between them, be they internal or external. The first nine articles deal with this theme historically; they offer a critical analysis of these questions in several classical German philosophers such as Leibniz, Kant, Herder, Fichte, Schelling, Hegel and Feuerbach. The nine articles that follow these present systematic approaches to the theme, establishing dialogues with various contemporary philosophers, both analytical and continental in inspiration.
