I took this photo of the Jefferson memorial in Washington, DC a few years ago. Jefferson can be criticized, like all freethinkers, for some “blind spots,” yet he continues to offer some wise reflection on reasonable living and a good, secular government.
This comes from the Monticello website (highlights in bold):
Thomas Jefferson was always reluctant to reveal his religious beliefs to the public, but at times he would speak to and reflect upon the public dimension of religion. He was raised as an Anglican, but was influenced by English deists such as Bolingbroke and Shaftesbury. Thus in the spirit of the Enlightenment, he made the following recommendation to his nephew Peter Carr in 1787: “Question with boldness even the existence of a god; because, if there be one, he must more approve the homage of reason, than that of blindfolded fear.”1 In Query XVII of Notes on the State of Virginia, he clearly outlines the views which led him to play a leading role in the campaign to separate church and state and which culminated in the Statute of Virginia for Religious Freedom: “The rights of conscience we never submitted, we could not submit. We are answerable for them to our God. The legitimate powers of government extend to such acts only as are injurious to others. But it does me no injury for my neighbour to say there are twenty gods, or no god. It neither picks my pocket nor breaks my leg. … Reason and free enquiry are the only effectual agents against error.2 Jefferson’s religious views became a major public issue during the bitter party conflict between Federalists and Republicans in the late 1790s when Jefferson was often accused of being an atheist.
