And if it be objected that one man's conscience may say that an act is right, which another man's conscience says is wrong, we must remember that the decision of a man's conscience, only refers to the man himself. It tells a man what is right for him, with his knowledge and surroundings, and it is quite possible that this may be wrong for another man.
These, then, are the moral attributes of the human race, and it follows at once that man is a free and responsible being. But as this conclusion is often disputed, because of the similarity between animals and men, and the difficulty of admitting that they also are free and responsible beings, or else of showing where the distinction lies, we must examine this subject.
(C.) Difference Between Animals and Men.
Now the bodily difference between certain animals and men is admittedly small; and though the accompanying mental difference is enormous, it is probably only one of degree; for all animals seem, to some slight extent, to possess a mind, which enables them at least to feel conscious of pleasure and pain. We must therefore pass on to the moral attributes of animals; and as we know nothing as to their feelings on the subject, it is difficult to say (referring to the first three points) whether they have a free will or not. Of course, if they have not, that would be a clear distinction between animals and men. But we have no right to assume this, and there is a good deal to be said on the other side, at least in regard to the higher animals, so the question had better be left open.
But with regard to the next point, that of known freedom, we are on surer ground; for the proof of man's believing himself to be free does not depend solely on his own feelings. It is shown by his acts, as it enables him to design, and it is doubtful if there is anything corresponding to this in animals. For though many of their works show design somewhere, it does not seem to be due to them. This kind of unconscious designing (which strange to say is most apparent in the lower forms of animal life) is called instinct, and there are at least three reasons for thinking that it differs from real design implying forethought.
The first is, that, if these works were due to the design of the animals themselves, they must possess intellectual powers of a very high order. Take, for instance, the well known example of the cells of bees. These are built on the most perfect mathematical principles, the three rhombs which close the hexagonal columns having the exact angles so as to contain the greatest amount of honey, with the least expenditure of wax. And as we require advanced mathematics and a book of logarithms to work out such problems, it is hard to see how the bees can do it. Nor is heredity of any use, for the bees which build cells are all workers (as they are called) and have no descendants; while those which have descendants are either drones or queens, and these do no building. Thus the cells are built by bees, none of whose ancestors have ever built cells; so the design cannot be ascribed to anything they have inherited from their parents.[3] Secondly, animals are only able to design in a few special cases, and in other respects they often act with the greatest stupidity. A bee, for example, with all its mathematics, cannot very often, if it has flown in through an open window, retrace its way, but will buzz helplessly against another which is shut.
[3] Encyc. Brit., 9th edit., vol. iii., pp. 490, 484. The angles are 109° 28' and 70° 32'.
Thirdly, the instincts of animals are practically the same, always and everywhere. They are not more advanced in some countries, than in others; or in some individuals, than in others. They are not even more advanced as time goes on. The last cell built by a bee is no better than the first, and no better, as far as we know, than cells built by bees thousands of years ago; while the young of animals, without any experience to guide them, have the same instincts as the old. Clearly, then, an animal's instinct is born with it, and not acquired; and therefore, any apparent design there may be in what is done by instinct cannot be attributed to the animal itself, any more than the design shown in its eyes, but to its Maker.
So far all is plain. It may, however, be urged that in some of the higher animals, especially those in contact with man, we do find certain acts which seem to imply forethought and design. A dog, for example, will bury a bone one day, and go and look for it the next. But when once it is admitted that what are apparently far more striking instances of design are to be explained by instinct, it seems better to explain them all in the same way.
And this is confirmed by the fact that even the higher animals do not appear to have any idea of responsibility, or any sense of right and wrong, which in man are the result of his known freedom. Of course, this also may be disputed, since as we punish a dog for doing what we dislike, it looks as if we held it responsible for the act. But this does not follow. We punish the dog to prevent its repeating the act. And it may avoid doing so, because its memory associates the act with pain, and not because it feels responsible for it, or considers it to be wrong. While in the vast majority of cases we never think of holding an animal responsible for its acts, or look upon its injuring anyone as a sin. We conclude, then, that moral attributes form the great distinction between animals and men; because though animals have, or may have, a free will, it is not a known freedom, so they are not able, like men, to design, and are hence not personal beings.
