His work engages with these domains from both historical-philosophical perspectives and systematic applications, addressing two central problems: (1) the foundation and legitimation of philosophical theories, and (2) the nature of thought and concepts, and their capacity to convey meaning through language. Through an extensive body of publications, Ferrer has examined the major figures of German Classical Philosophy, highlighting their contemporary relevance. By reinterpreting and updating the methodologies and theoretical insights developed between Kant and Schelling, he has proposed original responses to long-standing philosophical questions. His contributions defend a strong semantic connection between logic and reality, argue for the possibility of an ultimate grounding of philosophical knowledge despite its constitutive incompleteness, and trace how Kant, Fichte, Schelling, and Hegel established the decisive role of critique, skepticism, and negativity within contemporary philosophy. In his books and articles, Ferrer investigates the necessary incompleteness of knowledge, as well as conceptions of thought and self-reflection across Metaphysics, Aesthetics, Philosophy of Art, Literature, Architecture, and Philosophical Anthropology. His research spans a wide range of authors, from Antiquity to the present—including Aristotle, Cicero, Kant, Maimon, Jacobi, Fichte, Schelling, Hegel, Husserl, Heidegger, Wittgenstein, Pessoa, Borges, Escher, Adorno, Venturi, Gadamer, Jonas, McDowell, and Tomasello, among others. More recently, Ferrer has extended his focus to fundamental issues in the Philosophy of Nature and the Environment, with particular attention to the problem of the moral status of nature, as well as the debate between constructivism and realism in contemporary thought.
