Overeducate

You cannot overeducate the man you place in charge of a steam engine on board of a ship, and on whose judgment and skill a thousand valuable lives, to say nothing of property, may depend.

They are drilled and attend school on the premises, being taught by a capable mistress who understands their disabilities, and does not overeducate them, and yet tries to prevent their minds becoming fallow.

“You know, one thing I find particularly unpleasant about you Americans is your tendency to overeducate your women.”
