Green's newly published edition of Macaulay's correspondence allows us to understand the historian and political figure in her own terms as opposed to a representative of a supposedly coherent commonwealth or republican tradition, as she has often been considered since the work of Caroline Robbins and J. G. A. Pocock. Her contextually rich intellectual biography is strengthened by her immersion in Macaulay's correspondence and, for this reason alone, it offers a
significant advancement on Hill's pioneering study from 1992.
Karen Green has been a pioneer in the movement to include women's philosophical texts in the history of philosophy, concentrating on their contributions to political and ethical thought. In 1995 she published The Woman of Reason: Feminism, Humanism and Political Thought (Polity) and most recently A History of Women's Political Thought in Europe, 1700-1800 (Cambridge, 2014).
