It argues that an omnipotent, benevolent God is incompatible with notions of human free will and morality. The second portion of the pamphlet goes on to formulate that all motivations are derived from pain and that pain is met with an equal amount of pleasure. He then concludes that this means that man cannot be superior to animals because we are all equal in God's eyes. Franklin acknowledges how offensive this idea would be to the reader, and refuted it later.
In 1779, Franklin came to disagree with the points he printed in Dissertation and burned all the copies he possessed of the pamphlet but one for historical purposes. However, since he had already come to give several copies to friends of his, four original copies still survive. They are in the possession of the British Library, Library of Congress, John Carter Brown Library, and Yale University Library.
