Leonardo Polo’s Course on Theory of Knowledge (Eunsa, 1984-1996) can be understood as a work of philosophical synthesis of contemporary epistemologies (i.e. phenomenology, hermeneutics, analytic philosophy and personalism), that seeks to offer a deep explanation of human knowledge.


Throughout the four volumes, although the guiding thread througout the work is the original insight of the author, Polo analyzes several notions that are at the core of the History of Philosophy, i.e., conscience, intentionality, intellect, concept and judgment; at the same time, he classifies, criticizes and summarizes some of the most representative theories of knowledge of all time, i.e., Descartes, Leibniz, Kant and Hegel, among others.

Polo develops a fruitful analysis of the essence of knowledge from a new interpretation of the Aristotelian concept of act (enérgeia) as an immanent and limited operation of thought. According to Polo it is possible to distinguish between different levels and operations in human knowledge; and this distinction is axiomatic. It is also important to note that Polo makes a significant contribution, giving the notion of “habit” (héxis) –as Aristotle did with his theory of intellectual virtues or virtues of thought (cf. NE, VI)- a place in epistemology. For Polo, operations and habits are two different kinds of acts of knowledge.

Polo’s main goal for writing these books was to develop a realistic epistemology, that can be complementary to Traditional metaphysics. According to the Spanish philosopher, the crisis of metaphysics cannot be overcome without an adequate theory of human knowledge, because the question of the possibility of metaphysics is the question of the method of metaphysics. The method of metaphysics can be only the human knowledge.

In short, Polo’s epistemology, although inspired by the aristotelian-thomistic tradition, is not closed to other philosophical traditions and ways of thinking, i.e., in his explanations he dialogues with philosophers like Brentano, Husserl and Heidegger. Furthermore, he makes numerous references totheories about knowledge that have been proposed by some of the most speculative thinkers of all times, among which are Leibniz, Kant, and Hegel.

The communications and presentations of this International Congress seek to produce a fruitful dialogue between Polo’s epistemology and other philosophical traditions and their conceptions of human knowledge.
