"It is very strange, that, ever since mankind have taken it into their heads to trouble themselves so much about the education of children, they should never have thought of any other instruments to effect their purpose than those of emulation, jealousy, envy, pride, covetousness, and servile fear—all passions the most dangerous, the most apt to ferment, and the most fit to corrupt the soul, even before the body is formed. With every premature instruction we instil into the head, we implant a vice in the bottom of the heart."
