Robert Hanna

Robert Alan Hanna (born 1957) is a Canadian independent philosopher and the director of the philosophical working group Philosophy without Borders (PWB).

Life and work Hanna received his PhD in philosophy from Yale University in 1989 with a thesis supervised by Karsten Harries. Hanna has written works on logic and rationality, Immanuel Kant, analytic philosophy, and the philosophy of mind and knowledge.

In his work on Immanuel Kant, Hanna developed a cognitive-semantic interpretation of transcendental idealism. On this interpretation, the power of judgment is the central cognitive capacity through which intuition, conceptualization, imagination, and reason are unified in a single act of rational self-consciousness; thus, transcendental idealism becomes a theory of the a priori conditions under which objective experience and truth-apt judgment are possible.
