Fa. They can make known a few of their common wants and desires, but they cannot discourse, or communicate ideas stored up in the memory. It is this faculty which makes man an improvable being, the wisdom and experience acquired by one individual being thus transmitted to others, and so on in an endless series of progression.

There is no reason to suppose that the dogs of the present day are more knowing than those which lived a thousand years ago; but the men of this age are much better acquainted with numberless arts and sciences than their remote ancestors; since, by the use of speech and of writing (which is speech addressed to the eye), every age adds its own discoveries to all former ones. This knowledge of the past likewise gives man a great insight into the future. Shakspeare excellently defines man by saying that he is a creature “made with large discourse, looking before and after.”

Ch. Animals must surely know something of the future, when they lay up a store of provisions for the winter.

Fa. No—it is pretty certain that this is not the case, for they will do it as much the first year of their lives as any other. Young bees turned out of their hive, as soon as they have swarmed and got a habitation, begin laying up honey, though they cannot possibly foresee the use they shall have for it. There are a vast number of actions of this kind in animals which are directed to a useful end, but an end which the animal knows nothing of. And this is what we call instinct, and properly distinguish from reason. Man has less of it than almost any other animal, because he wants it less. Another point of essential difference is, that man is the only animal that makes use of instruments in any of his actions. He is a tool-making and machine-making animal. By means of this faculty alone he is every where lord of the creation, and has equally triumphed over the subtlety of the cunning, the swiftness of the fleet, and the force of the strong. He is the only animal that has found out the use of fire, a most important acquisition!

Ch. I have read of some large apes that will come and sit round a fire in the woods when men have left it, but have not the sense to keep it in, by throwing on sticks.

Fa. Still less then could they light a fire. In consequence of this discovery man cooks his food, which no other animal does. He alone fences against the cold by clothing as well as by fire. He alone cultivates the earth, and keeps living animals for future uses.

Ch. But have not there been wild men bred in the woods that could do none of these things?

Fa. Some instances of this kind are recorded, and they are not to be wondered at; for man was meant to be a gregarious animal, or one living in society, in which alone his faculties have full scope, and especially his power of improving by the use of speech. These poor solitary creatures, brought up with the brutes, were in a state entirely unnatural to them. A solitary bee, ant, or beaver, would have none of the skill and sagacity of those animals in their proper social condition. Society sharpens all the faculties, and gives ideas and views which never could have been entertained by an individual.

Ch. But some men that live in society seem to be little above the brutes, at least when compared with other men. What is a Hottentot in comparison with one of us?

Fa. The difference, indeed, is great; but we agree in the most essential characters of man, and perhaps the advantage is not all on our side. The Hottentot cultivates the earth and rears cattle. He not only herds with his fellows, but he has instituted some sort of government for the protection of the weak against the strong; he has a notion of right and wrong, and is sensible of the necessity of controlling present appetites and passions for the sake of a future good. He has therefore morals. He is possessed of weapons, tools, clothing, and furniture of his own making. In agility of body, and the knowledge of various circumstances relative to the nature of animals, he surpasses us. His inferiority lies in those things in which many of the lowest class among us are equally inferior to the instructed.
