Excuses, Justifications and the Normativity of Expressive Behaviour

In this article, I look at the role of appeals to the emotions in criminal law defences. A position commonly held is that appeals to the emotions can excuse but cannot justify. However, we should be careful that this view does not rest on too simple and non-cognitive a view of the emotions. I contrast a simple picture, according to which action from emotion involves loss of rational control, with the more Aristotelian picture recently offered by RA Duff. I then look at John Gardner's theory of excuses, which seeks to avoid the non-cognitive account of action from emotion as loss of rational control, but nevertheless denies that reference to the emotions can even partially justify. I argue that what is at issue between Gardner and Duff is what Gardner calls the 'no-difference' thesis, namely that the reasons that count in favour of an emotion count also in favour of action done from that emotion. I conclude that Gardner has not yet explained why we should reject the no-difference thesis.
