According to Kant, being purely rational or purely reasonable and being autonomously free are one and the same thing. But how can this be so? How can my innate capacity for pure reason ever motivate me to do anything, whether the right thing or the wrong thing? What I will suggest is that the fundamental connection between reason and freedom, both for Kant and in reality, is precisely our human biological life and spontaneity of the will, a conjunctive intrinsic structural (...) property of our animal bodies, which essentially constitutes human personhood and rational agency. I say ‘suggest’ because, obviously, no proper argument for such a conclusion could ever be worked out in a short essay. I would nevertheless like to motivate my suggestion by way of a commentary on the second part of Adrian Moore's extremely rich and interesting recent book, Noble in Reason, Infinite in Faculty.
