A true and sufficient culture can never, as we conceive, be founded on literature and language alone. No mind can be truly liberalized without imbibing and assimilating the fundamental principles of science. There is darkness in the mind that believes that anything can come out of nothing and which has never obtained a glimpse of the exactness with which Nature solves her equations. In the region of mechanics alone there are a thousand beautiful and varied illustrations of the unfailing constancy of natural laws. It is a liberal education to trace the operation of one law under numberless disguises, and thus arrive at an ineradicable conviction that the same law must be reckoned with always and everywhere. The persistence of force, the laws of the composition and resolution of forces, the laws of falling bodies and projectiles, the conservation of energy, the laws of heat, to mention only a few heads of elementary scientific study, are capable, if properly unfolded and illustrated, of producing in any mind open to large thoughts a sense of harmony and a trust in the underlying reason of things, which are constitutive elements of the very highest culture. Only, care must be taken to approach these studies in a right spirit. There is a way of regarding the laws of Nature which tends to vulgarize rather than refine the mind. If we approach Nature merely as something to be exploited, we get no culture from the study of it; but if we approach it as the great men of old did, and feel that in learning its laws we are grasping the thoughts which went to the building of the universe, and, by so doing, are affirming our own high calling as intelligent beings, then every moment given to the study of Nature means intellectual, moral, and spiritual gain. When we look into literature there is much to charm, much to delight and satisfy; and doubtless, in relation to what any one man can accomplish, the field is infinite; but still we know we are looking into the limited. On the other hand, when we are face to face with Nature, we know we are looking into the infinite, and that, however many veils we may take away, there is still "veil after veil behind."
