“When once we quit the basis of sensation, all is in the wind. To talk of immaterial existences is to talk of nothings. To say that the human soul, angels, god, are immaterial, is to say they are nothings, or that there is no god, no angels, no soul. I cannot reason otherwise: but I believe I am supported in my creed of materialism by Locke, Tracy, and Stewart. {Letter to John Adams, from Monticello, 15 August 1820}” ReasonAtheismMaterialismAngelsLockeTracyCreedJohn AdamsJohn LockeAdamsStewartAntoine Destutt De TracyAntoine Louis Claude DestuttComte De TracyDugald StewartJohn Stewart Mill Book:Letters of Thomas Jefferson Source: Letters of Thomas Jefferson
