In examining this creature we should find that it shared in all the wants of those beneath him, but that it supplied its wants, not by the use of instincts, but of reason. Over and above, however, man's physical wants, we should find that he had mental wants; and with these wants faculties also, by which he could supply them. Supply all the physical wants of an animal, and having none besides, it will lie still for hours or days until hunger stirs it to renewed exertion. Supply all man's physical wants, and his mental wants then develop into full activity. Give him the lowest and basest drudgery; make him work morning, noon, and night in the meanest occupations, for the supply of merely physical necessities, and, though you can infinitely degrade, you cannot destroy his mental powers. He still thinks, still connects causes and effects. But our purpose will be best answered by taking the case of those whose faculties are most highly cultivated. Has nature supplied a proper field for the exercise of the mental powers, not merely of Fuegians, but of the most highly developed man? You know that she has. Take the senses which he has in common with the animals, but see what vast means have been provided by which he can make an intellectual use of them. What arts and sciences, painting, music, harmony, numbers, eloquence, have grown out of their use. As for our mental powers, think only of the vast number of ologies which are claiming admission into our very normal schools. Think only of all our learned Associations, our Royal Societies, our Social Congresses, our British Museums full of books, which have been written, and are waiting only to be read, and you must own that men do use their mental powers, and have means enough for a more ample use of them. Nature makes us use our mental powers to some extent. She encourages us to use them thoroughly and earnestly.
