In the School-Room Chapters in the Philosophy of Education Quotes

“The person who has learned to express a thought with entire exactness and idiomatic propriety in two languages; or where, from the want of analogy between the two languages, he finds this impracticable, to perceive the exact shade of difference between the two expressions; who can trace historically and logically the present meaning of a word from its original starting-point in reason and fact, and mark intelligently its gradual departures and their causes; who can perceive the exact difference between words and phrases nearly synonymous, and who can express that difference in terms clear and intelligible to others,—that person has already attained both a high degree of intellectual acumen himself, and an important means of producing such acumen in others.”
― John Seely Hart, In the School-Room Chapters in the Philosophy of Education
