Respect for children means respect for the adults that they will one day become; it means helping them to the knowledge, skills, and social graces that they will need if they are to be respected in that wider world where they will be on their own and no longer protected. For the teacher, respect for children means giving them whatever one has by way of knowledge, teaching them to distinguish real knowledge from mere opinion, and introducing them to the subjects that make the mind adaptable to the unforeseen. To dismiss Latin and Greek, for example, because they are not “relevant” is to imagine that one learns another language in order, as Matthew Arnold put it, “to fight the battles of life with the waiters in foreign hotels.”
