While it is possible to apply Locke's general principles of education to all children, and contemporaries such as Coste certainly did so, Locke himself, despite statements that may imply the contrary, believed that "Some Thoughts" applied only to the wealthy and the middle-class (or as they would have been referred to at the time, the "middling sorts"). One of Locke's conclusions in "Some Thoughts Concerning Education" is that he "thinka Prince, a Nobleman, and an ordinary Gentleman's Son, should have different Ways of Breeding." As Peter Gay writes, "[it never occurred to him that every child should be educated or that all those to be educated should be educated alike. Locke believed that until the school system was reformed, a gentleman ought to have his son trained at home by a tutor. As for the poor, they do not appear in Locke's little book at all."
