"We hold these truths to be sacred and undeniable" in a draft of the Declaration of Independence changes it instead into an assertion of rationality. The scientific mind of Franklin drew on the scientific determinism of Isaac Newton and the analytic empiricism of David Hume and Gottfried Leibniz. In what became known as "Hume's Fork" the latters' theory distinguished between synthetic truths that describe matters of fact, and analytic truths that are self-evident by virtue of reason and definition.
Benjamin FranklinThank God! we are in the full enjoyment of all these privileges. But can we be taught to prize them too much? or how can we prize them equal to their value, if we do not know their intrinsic worth, and that they are not a gift bestowed upon us by other men, but a right that belongs to us by the laws of God and nature?
Benjamin Franklin
