The plaques at Pietermaritzburg railway station commemorating Mahatma Gandhi’s experience of racist injustice in 1893 never fail to move me. More important, they also never fail to inspire me. They remind me that when we find ways to put conscience to work effectively, good can triumph over evil. So it seems to me that the main challenge now facing society, besides curbing its greed for energy and its contempt for the environment, is to find new and powerful ways of putting conscience to work. As I embark on a new phase of my work in applied ethics, under the banner of a structure I have named compass ethics, I see this is the most valuable work I could do in my post-academic days.
