 After his return from exile, Locke published An Essay Concerning Human Understanding and The Two Treatises of Government. In addition, Popple’s translation of Locke’s A Letter Concerning Toleration was also published. It is worth noting that the Two Treatises and the Letter Concerning Toleration were published anonymously. Locke took up residence in the country at Oates in Essex, the home of Sir Francis and Lady Masham (Damaris Cudworth). Locke had met Damaris Cudworth in 1682 and became involved intellectually and romantically with her. She was the daughter of Ralph Cudworth, the Cambridge Platonist, and a philosopher in her own right. After Locke went into exile in Holland in 1683, she married Sir Francis Masham. Locke and Lady Masham remained good friends and intellectual companions to the end of Locke’s life. During the remaining years of his life, Locke oversaw four more editions of the Essay and engaged in controversies over the Essay most notably in a series of published letters with Edward Stillingfleet, Bishop of Worcester. In a similar way, Locke defended the Letter Concerning Toleration against a series of attacks. He wrote The Reasonableness of Christianity and Some Thoughts on Education during this period as well.
