Philip Pettit's narrative of the eclipse of republican by liberal liberty in late eighteenth-century Britain adds colour and plausibility to his analytical contrast between republican and liberal liberty. The narrative supports his argument that republicanism and liberalism can be helpfully contrasted in terms of non-domination and non- interference conceptions of liberty. While the narrative has not been scrutinized in the literature, it is in fact flawed. The flaws raise new questions about how stringent a value liberty as non-domination is and what motivated the value. The flaws also raise new questions about the significance of liberty as non-interference within the very strand of liberalism that Pettit focuses upon. Finally, the article casts doubt on some aspects of Quentin Skinner's interpretation of republican liberty.
