John Locke (1632-1704) is widely regarded as one of the most influential of the Enlightenment philosophers. This volume, edited by J. W. Adamson and published as a second edition in 1922, contains two of John Locke's essays concerning education; Some Thoughts Concerning Education (1693) and Of the Conduct of the Understanding (1706). Some Thoughts Concerning Education expands on Locke's pioneering theory of mind by explaining how to educate a child using three complementary methods: the development of a healthy body; the formation of a virtuous mind; and the pursuit of an academic curriculum including the emerging sciences, mathematics and languages. Of the Conduct of the Understanding continues the theme of the earlier essay by describing how to develop rational thought. For over a century after the publication of these essays, John Locke's views on education were considered authoritative, and his work was translated into almost all major European languages.
