ABSTRACT
When Wanda returns a lost wallet to its owner, we praise her for having done the right thing, and consider her to be an ethical agent, worthy of praise. This presupposes two key ideas: that Wanda freely chose to return the wallet (i.e. she is autonomous) and that she chose to do so for good reasons (i.e. she is rational or reasonable). These two notions seem to be central to morality.
