Abstract

In this chapter, I examine the three main arguments of On Liberty: first, a largely epistemic argument that individual and social improvement, because they depend so much on intellectual development, require social conditions allowing for free discussion and “experiments of living;” second, an argument that individuality, or self‐directedness, is itself a key constitutive part of the individual human good; third, the introduction of a principle – the liberty principle – according to which only considerations of nonconsensual “harm to others” may justify social or political interference. I then consider whether Mill, as a liberal utilitarian, has anything to offer the public reason tradition that dominates contemporary liberal thought.
