Slavery, Carbon, and Moral Progress

My goal in this paper is to shed light on how moral progress actually occurs. I begin by restating a conception of moral progress that I set out in previous work, the “Naïve Conception,” and explain how it comports with various normative and metaethical views. I go on to develop an index of moral progress and show how judgments about moral progress can be made. I then discuss an example of moral progress from the past—the British abolition of the Atlantic slave trade—with a view to what can be learned from this for a contemporary struggle for moral progress: the movement to decarbonize the global economy. I close with some thoughts about how moral progress actually occurs.
