This book reassesses the ethics of reason in the Age of the Reason, making use of the neglected category of conscience. Arguing that conscience was a central feature of British Enlightenment ethical rationalism, the book explores the links between Enlightenment philosophy and modern secularisation, while responding to longstanding criticisms of rational intuitionism and the analogy between mathematics and morals, derived from David Hume and Immanuel Kant. Questioning in what sense British Enlightenment ethical rationalism can be associated with a secularising ‘Enlightenment project’, Daniel investigates the extent to which contemporary, and secular liberal, invocations of reason and conscience rely on the early modern Christian metaphysics they have otherwise disregarded. The chapters cover a rich collection of subjects, ranging from the Enlightenment’s secular legacy, reason and conscience in the history of ethics, and controversies in the Scottish Enlightenment, to the role of British moralists such as John Locke, Joseph Butler and Adam Smith in the secularisation of reason and conscience. Each chapter expertly refines Enlightenment ethical rationalism by reinterpreting its most influential proponents in eighteenth-century Britain – the followers of ‘Isaac Newton’s bulldog’ Samuel Clarke – including Richard Price (Edmund Burke’s opponent over the French Revolution) and John Witherspoon (the only clergyman to sign the US declaration of Independence).

The Sovereignty of Reason is a survey of the rule of faith controversy in seventeenth-century England. It examines the arguments by which reason eventually became the sovereign standard of truth in religion and politics, and how it triumphed over its rivals: Scripture, inspiration, and apostolic tradition. Frederick Beiser argues that the main threat to the authority of reason in seventeenth-century England came not only from dissident groups but chiefly from the Protestant theology of the Church of England. The triumph of reason was the result of a new theology rather than the development of natural philosophy, which upheld the orthodox Protestant dualism between the heavenly and earthly. Rationalism arose from a break with the traditional Protestant answers to problems of salvation, ecclesiastical polity, and the true faith. Although the early English rationalists were not able to defend all their claims on behalf of reason, they developed a moral and pragmatic defense of reason that is still of interest today. Beiser's book is a detailed examination of some neglected figures of early modern philosophy, who were crucial in the development of modern rationalism. There are chapters devoted to Richard Hooker, the Great Tew Circle, the Cambridge Platonists, the early ethical rationalists, and the free-thinkers John Toland and Anthony Collins.

This book examines the importance of the Enlightenment for understanding the secular outlook of contemporary Western societies. It shows the new ways of thinking about religion that emerged during the 17th and 18th centuries and have had a great impact on how we address problems related to religion in the public sphere today. Based on the assumption that political concepts are rooted in historical realities, this collection combines the perspective of political philosophy with the perspective of the history of ideas. Does secularism imply that individuals are not free to manifest their beliefs in public? Is secularization the same as rejecting faith in the absolute? Can there be a universal rational core in every religion? Does freedom of expression always go hand in hand with freedom of conscience? Is secularism an invention of the predominantly Christian West, which cannot be applied in other contexts, specifically that of Muslim cultures? Answers to these and related questions are sought not only in current theories and debates in political philosophy, but also in the writings of Immanuel Kant, Benedict Spinoza, Thomas Hobbes, Anthony Collins, Adriaan Koerbagh, Abbé Claude Yvon, Giovanni Paolo Marana, and others.

The authors revisit the idea that Enlightenment spearheaded secularization. This book invites all to look at the Enlightenment religiosity as founded on a merger of religious criticism and heterodoxy.

A wide-ranging collection of studies on Enlightenment and religion in eighteenth-century England.

Originally published in 1963. Perhaps the most generative ethical question of eighteenth-century France was how to live a virtuous and happy life at the same time. During the Age of Enlightenment, Christianity fell out of vogue as the dominant and authoritative moral code. In place of Christianity's emphasis on sin and redemption in light of a supposed afterlife, present happiness became recognized as an appropriate end goal among French Enlightenment thinkers. French intellectuals struggled to find equilibrium between nature (a person's individual goals and needs) and culture (the political, economic, and social organization of humans for a collective good). Enlightenment discourse generated a unique cultural moment in which thinkers addressed the problems of humans' moral coexistence through the dichotomy of nature and culture. Lester Crocker addresses these questions in an overview of ethical thought in eighteenth-century France.
