Rationalism in ethics
I believe I was the first person to note in print just how Aristotelian Oakeshott's analysis of rationalism is, although I must credit Noel O'Sullivan for dropping the hint that got me going in that direction. Here is the kind of thing I was getting at: "At the start of the Nicomachean Ethics , Aristotle observes that moral action does not arise from deliberation. In order to think clearly about virtue, one must first already have a virtuous disposition formed by good habits. Aristotle drily remarks that the endless ethical debate of some philosophers is really just a sophisticated way of doing nothing. You become virtuous – and thus able to understand virtue – by acting virtuously. Nobody ever reasoned their way into right living." "...the endless ethical debate of some philosophers is really just a sophisticated way of doing nothing": Peter Singer springs instantly into my mind!
