Constant worked on this study of humanity’s religious forms and development throughout his life, eventually publishing five volumes between 1824 and 1831. His aims were to relate religious forms to their historical contexts and civilizational developments, to show partisans of the new post-revolutionary order that the religious impulse was natural to the human heart, and to show religious reactionaries that history had left them behind and that the natural state of the religious sentiment was an unfettered “spirituality” left free to find new forms of expression.

Nick Capaldi, the Legendre-Soulé Distinguished Chair of Business Ethics in the School of Business of Loyola University, New Orleans, outlines David Hume's ambitious "Project" with a list of 8 "theses", the last of which states that "Liberty is the Central Theme." Capaldi's gloss on this thesis is "The ultimate ontological reality is the individual human agent; there is no institution or practice that transcends the individual; the legitimacy of any practice is based on the acquiescence of individuals.  Acquiescence is not consent. There is no philosophical argument for liberty: it is the default position.  Given its unique history, England was able to preserve and elaborate this insight in large part because of its inherent disposition to distrust abstractions – this is the British Intellectual Inheritance, and Hume's philosophical practice as well as his History is the only meaningful kind of account that can be given." Capaldi is joined in this month's discussion by Daniel Klein who is professor of economics and JIN Chair at the Mercatus Center at George Mason University; Chandran Kukathas who holds the Chair of Political Theory in the Department of Government at the London School of Economics; Andrew Sabl who is Orrick Fellow and Visiting Professor in the Program on Ethics, Politics and Economics, Yale University; and Mark Yellin of Liberty Fund.

In this month's discussion Henry C. Clark, who is a visiting professor in the Political Economy Project at Dartmouth College and the editor and translator of Denis Diderot's Encyclopedic Liberty (Liberty Fund, 2016), explores some of the currents of political thought which swept through the massive 17 volume Encyclopédie, ou Dictionnaire raisonné des sciences, des arts et des métiers which appeared over a 15 year period between 1751 and 1765. In his lead essay he argues that, although it offended at times the Church and the French government, it could be read in ambiguous ways. The influences of John Locke, Voltaire, and Montesquieu are assessed and he concludes that the Encyclopédie was "not so much an ideology as a quarry" from which different readers were destined to draw different kinds of inspiration. Hank is joined in this discussion by Dan Edelstein who is William H. Bonsall Professor of French, Stanford University; Andrew Jainchill, Associate Professor, Department of History, Queens University, Kingston Ontario; and Kent Wright, Associate Professor School of Civic and Economic Thought and Leadership, Arizona State University.

In this Liberty Matters online discussion forum we explore a number of issues concerning the role ideas have had in changing societies by examining several historical examples such as the anti-slavery movement in Britain and America in the first half of the 19th century, Richard Cobden and the free trade movement, and the rebirth of classical liberal and free market ideas after the Second World War. In the Lead Essay David Hart surveys the field of ideological movements and present a theory of ideological production and distribution based upon Austrian capital theory as it might be applied to the production of ideas. The commentators are Stephen Davies who is education director at the Institute of Economic Affairs in London; David Gordon who is a Senior Fellow at the Mises Institute; Jason Kuznicki who is a Research Fellow at the Cato Institute and Editor, Cato Unbound; Peter Mentzel who is a Senior Fellow at Liberty Fund; Jim Powell who is a Senior Fellow at the Cato Institute; George H. Smith who is an independent scholar and contributor to ; and Jeffrey Tucker who is a distinguished fellow at the Foundation for Economic Education, editor at Laissez Faire Books, and founder of Liberty.me .
