great things have been done, in the progress of the work of creation, we naturally think that even greater things than these, still remain to be done. 6. But then, on the other hand, there is an immense difficulty in supposing, even in imagining, any further change, at all commensurate in kind and degree, with the step which carried the world from a mere brute population, to a human population. In a proportion in which the two first terms are _brute_ and _man_, what can be the third term? In the progress from mere Instinct to Reason, we have a progress from blindness to sight; and what can we do more than see? When pure Intellect is evolved in man, he approaches to the nature of the Supreme Mind: how can a creature rise higher? When mere impulse, appetite, and passion are placed under the control and direction of duty and virtue, man is put under Divine Government: what greater lot can any created being have? 7. And the difficulty of conceiving any ulterior step at all analogous to the last and most wonderful of the revolutions which have taken place in the condition of the earth's inhabitants, will be found to grow upon us, as it is more closely examined. For it may truly be said, the change which occurred when man was placed on the earth, was not one which could have been imagined and constructed beforehand, by a speculator merely looking at the endowments and capacities of the creatures which were previously living. Even in the way of organization, could any intelligent spectator, contemplating anything which then existed in the animal world, have guessed the wonderful new and powerful purposes to which it was to be made subservient in man? Could such a spectator, from seeing the _rudiments of a Hand_, in the horse or the cow, or even from seeing the hand of a quadrumanous animal, have conjectured, that the Hand was, in man, to be made an instrument by which infinite numbers of new instruments were to be constructed, subduing the elements to man's uses, giving him a command over nature which might seem supernatural, taming or conquering all other animals, enabling him to scrutinize the farthest regions of the universe, and the subtlest combinations of material things? 8. Or again; could such a spectator, by dissecting the tongues of animals, have divined that the Tongue, in man, was to be the means of communicating the finest movements of thought and feeling; of giving one man, weak and feeble, an unbounded ascendency over robust and angry multitudes; and, assisted by the (writing) hand, of influencing the intimate thoughts, laws, and habits of the most remote posterity?
