where did the idea of unalienable rights come from
Natural and legal rights The distinction between alienable and unalienable rights was introduced by Francis Hutcheson. In his Inquiry into the Original of Our Ideas of Beauty and Virtue (1725), Hutcheson foreshadowed the Declaration of Independence, stating: “For wherever any Invasion is made upon unalienable Rights, there must arise either a perfect, or external Right to Resistance. . . . Unalienable Rights are essential Limitations in all Governments.” Hutcheson, however, placed clear limits on his notion of unalienable rights, declaring that “there can be no Right, or Limitation of Right, inconsistent with, or opposite to the greatest publick Good."[17] Hutcheson elaborated on this idea of unalienable rights in his A System of Moral Philosophy (1755), based on the Reformation principle of the liberty of conscience. One could not in fact give up the capacity for private judgment (e.g., about religious questions) regardless of any external contracts or oaths to religious or secular authorities so that right is "unalienable." Hutcheson wrote: "Thus no man can really change his sentiments, judgments, and inward affections, at the pleasure of another; nor can it tend to any good to make him profess what is contrary to his heart. The right of private judgment is therefore unalienable."[18]
