What drives moral revolutions like the legal abolition of slavery and women’s right to vote? The importance of having an answer to this question lies in the hope of it being able to help us create moral progress in the future. This can be changing harmful practices and traditions like honour killing, child marriage, genital mutilation and political corruption. Furthermore, a wrong or insufficient picture of the dynamics of change, held by e.g. politicians or NGOs and incorporated into laws and (...) institutions, can lead to misfired inventions, wasted resources and possibly human harm. If we lack conceptual clarity and empirical insights, we will have trouble making good decisions. However, before answering the above question we need to consider what answering it entails. This article therefore discusses which form an understanding of the dynamics of moral revolutions should take in order to best help us create progress. I do so by critically investigating one currently dominant way of approaching this issue, namely the idea that we should produce a general explanatory theory of the fundamental dynamics of change. In order to expose the problems in this approach, I engage with a contemporary example of it, namely Appiah’s work on moral revolutions, and demonstrate that honour codes cannot have the explanatory role, which Appiah claims for them. The article concludes by pointing to alternative models of understanding the dynamics of moral revolutions and changes. (shrink)
