J. S. Mill and the Art of Compromise The word compromise means a kind of agreement and a concession to something harmful or wrong. I argue that particularly this second sense is quite relevant in the ethics of political action. John Stuart Mill focused upon this issue in his Thoughts on Parliamentary Reform 1859. I outline Mill's doctrine on compromise looking at the external and internal features of an acceptable measure of compromise. These features provide a set of conditions necessary (...) in order for compromise to take place, but they do not guarantee sufficient conditions. In order to assess Mill's political coherence and to draw a general distinction between strategic and ethical compromises the paper concludes by considering two compromise measures that Mill adopted while he was a Member of Parliament.
