"When he arrived in Amsterdam at age fifty-one [1683], Locke had published nothing. During what was clearly a transformational period, he used his time in Holland to talk with other independent thinkers who had been hounded into exile by the governments and churches of their own countries. Although Spinoza was dead, Locke certainly met many of the philosopher's admirers and enemies. He was well acquainted with nonconformist Protestant Collegiants, and his later writings would advocate complete toleration for all forms of Protestantism. At the time of Locke's death, his library contained all of Spinoza's published works as well as many political and religious disputations, in many languages, in which Spinoza's ideas were vigorously debated. Locke, like Hobbes, Adam Smith, and David Hume, is much more widely recognized than Spinoza in the United States as an influence upon the Enlightenment views of the American founders, but the more radical Spinoza's voice can be heard in both the Declaration of Independence and the Bill of Rights. It is not surprising that Thomas Jefferson's library contained Spinoza's collected works, which were more readily available at the end of the eighteenth century than in Locke's time."
