Liberty of conscience and freedom of thought are twin, core components of modern life in societies across the world. The ability to pursue one's vision of the right and the good, coupled with liberty to pursue individual reason and enlightenment, helped produce so much of modern life that we may be apt to forget that libertarian philosophy was not dictated by Nature. Freethought and Freedom surveys the long history of religious and intellectual liberty, exploring their key ideas along the way.

There is a well-worn image and phrase for libertarianism: "atomized individualism." This hobgoblin has spread so thoroughly that even some libertarians think their philosophy unreservedly supports private persons, whatever the situation, whatever their behavior. Smith's Self-Interest and Social Order in Classical Liberalism, corrects this misrepresentation with careful intellectual surveys of Hume, Smith, Hobbes, Butler, Mandeville, and Hutcheson and their respective contributions to political philosophy.

For almost a century after the U.S. Constitution went into effect, few Americans seem to have questioned the legitimacy of the Revolution. Since the Progressive generation of historians began the work of serious criticism and revision, however, students of American life have largely learned to live with a more complicated understanding of the revolutionary legacy. Smith's treatment of the era charts space for libertarians to both criticize and revere the American heritage.
