Constructivism is at the heart of a pedagogical philosophy going back to Vico, whose view of the interrelationship of the arts and sciences sought to reconstitute the classical paideia. The Vichian idea that human beings can only know the truth of what they themselves have made has theoretical and practical consequences for Vico's pedagogy and view of the university. Vico's ideas on education are extended in the modern period by such thinkers as Cassirer, Piaget and Bateson. At the basis of (...) Cassirer's pedagogical philosophy is his theory of the symbol, the symbol being a universal and transcendent modality in culture. The result of this unifying theory is that symbolism, which is pervasive across the disciplines, provides a moral and ethical means for integrating communication about teaching. Cassirer's thought is compatible with Piaget's, which emphasizes the pluralism of experience and the role of dynamic learning in the construction of meaningful order. Piaget's constructivism assumes that an operational bridge exists to link together the hard sciences, the human sciences, and the historical disciplines. This systems view of epistemological matters is similar in many respects to the one advanced by Gregory Bateson, which is explored in the paper's final section. (shrink)

This commentary to Nescolarde-Selva and Usó-Doménech’s (Reality, systems and impure systems. Foundations of Science 2013) links ideas in their paper to radical constructivism and raises two questions. (1) Would it be helpful to substitute the constructivist notion of viability for the traditional notion of truth with its connotations of relating language and reality? (2) Is the link made to issues in ontological philosophy important since the implicit constructivist epistemology of the paper considers mathematical ideas are just as real as ideas (...) about objects.

An agent’s knowledge of her own intentional actions (agential knowledge) is non-observational. Yet, intentional actions typically consist of happenings external to the agents. A theory is needed to explain how agents are warranted to form such beliefs independent of observation. This paper first argues for three desirable features of an ideal theory about agential knowledge. After showing that no existing theories possess all three, a novel theory that does is presented. According to this theory, agential knowledge is the same kind (...) of knowledge as the Kripkean contingent a priori: they are knowledge justified a priori by stipulation. (shrink)
