James L. Richardson identified five central themes in Locke's writing: individualism, consent, the concepts of the rule of law and government as trustee, the significance of property and religious toleration. Although Locke did not develop a theory of natural rights, he envisioned individuals in the state of nature as being free and equal. The individual, rather than the community or institutions, was the point of reference. Locke believed that individuals had given consent to government and therefore authority derived from the people rather than from above. This belief would influence later revolutionary movements.
