"[A]s there is a curiosity about intellectual matters which is futile, and merely a disease, so there is certainly a curiosity,—a desire after the things of the mind simply for their own sakes and for the pleasure of seeing them as they are,—which is, in an intelligent being, natural and laudable. Nay, and the very desire to see things as they are implies a balance and regulation of mind which is not often attained without fruitful effort, and which is the very opposite of the blind and diseased impulse of mind which is what we mean to blame when we blame curiosity. Montesquieu says:—"The first motive which ought to impel us to study is the desire to augment the excellence of our nature, and to render an intelligent being yet more intelligent." This is the true ground to assign for the genuine scientific passion, however manifested, and for culture, viewed simply as a fruit of this passion; and it is a worthy ground, even though we let the term curiosity stand to describe it."
