 Locke’s main educational writing is Some Thoughts Concerning Education, and it is based on letters of advice that Locke wrote to his friend Edward Clarke. This context means that the book assumes a person of relative wealth who will be overseeing the education of his son. The book was extremely popular and went through numerous editions in the century after its publication. One of the striking features of the book is the way parents are encouraged to develop and augment the child’s love for praise and esteem (Some Thoughts, 56–62). Cultivating this desire helps the child learn to hold in check other harmful desires, such as the desire for dominion, and to learn to control impulses by not acting on them until after reflecting on them.
