 Locke treated children as human beings in whom the gradual development of rationality needed to be fostered by parents. Locke urged parents to spend time with their children and tailor their education to their character and idiosyncrasies, to develop both a sound body and character, and to make play the chief strategy for learning rather than rote learning or punishment. Thus, he urged learning languages by learning to converse in them before learning rules of grammar. Locke also suggests that the child learn at least one manual trade.
