Book excerpt: This collection offers a timely opportunity to re-examine both the coherence of the concept of an ‘early Enlightenment’, and the specific contribution of natural law theories to its formation. It reassesses the work of major thinkers such as Grotius, Hobbes, Locke, Malebranche, Pufendorf and Thomasius, and evaluates the appeal and importance of the discourse of natural jurisprudence both to those working inside conventional educational and political structures and to those outside.
