Note 4 — Chapter XI · THE INTELLECTUAL EFFECT OF MANUAL TRAINING.
Reading edition
“I believe that well-advised practice in any of the constructive arts involving not more than one-third of the student’s time will yield as much mental improvement as will result if the whole time be devoted to study from text-books.”—Prof. Wm. F. M. Goss, six years Director of the Department of Practical Mechanics of Purdue University.
“And reflect that he will learn more by one hour of manual labor than he will retain from a whole day’s verbal instructions.”—“The Emilius and Sophia” of J. J. Rousseau, Vol. II., p. 64. London: 1767.
“The things themselves are the best explanations. I can never enough repeat it, that we make words of too much consequence; with our prating modes of education we make nothing but praters.”—Ibid., p. 46.
