Amongst the animals, wild beasts, such as lions, have their biggest muscles about the shoulders, thighs, and legs; and therefore these animals are nimble, brisk, nervous, and ready to rush forward. Their jaw-bones are prodigiously large, in proportion to the rest of their bodies. They have teeth and claws, which serve them, as terrible weapons, to tear in pieces and devour other animals. For the same reason, birds of prey, such as eagles, have a beak and pounces that pierce everything. The muscles of their pinions are extreme large and brawny, that their wings may have a stronger and more rapid motion: and so those creatures, though somewhat heavy, soar aloft and tower up easily to the very clouds, from whence they shoot, like a thunderbolt, on the quarry they have in view. Other animals have horns. The greatest strength of some lies in their backs and necks; and others can only kick. Every species, however, has both offensive and defensive arms. Their hunting is a kind of war, which they wage one against another, for the necessities of life. They have also laws and a government among themselves. Some, like tortoises, carry the house wherein they were born; others build theirs, as birds do, on the highest branches of trees, to preserve their young from the insult of unwinged creatures, and they even lay their nests in the thickest boughs to hide them from their enemies. Another, such as the beaver, builds in the very bottom of a pond the sanctuary he prepares for himself, and knows how to cast up dikes around it, to preserve himself by the neighbouring inundation. Another, like a mole, has so pointed and so sharp a snout, that in one moment he pierces through the hardest ground in order to provide for himself a subterranean retreat. The cunning fox digs a kennel with two holes to go out and come in at, that he may not be either surprised or trapped by the huntsmen. The reptiles are of another make. They curl, wind, shrink, and stretch by the springs of their muscles; they creep, twist about, squeeze, and hold fast the bodies they meet in their way; and easily slide everywhere. Their organs are almost independent one on the other; so that they still live when they are cut into two. The long-legged birds, says Cicero, are also long-necked in proportion, that they may bring down their bill to the ground, and take up their food. It is the same with the camel; but the elephant, whose neck through its bigness would be too heavy if it were as long as that of the camel, was furnished with a trunk, which is a contexture of nerves and muscles, which he stretches, shrinks, winds, and turns every way, to seize on bodies, lift them up, or throw them off: for which reason the Latins called that trunk a hand.
Certain animals seem to be made on purpose for man. The dog is born to caress and fawn upon him; to obey and be under command; to give him an agreeable image of society, friendship, fidelity, and tenderness; to be true to his trust; eagerly to hunt down, course, and catch several other creatures, to leave them afterwards to man, without retaining any part of the quarry. The horse, and such other animals, are within the reach and power of man; to ease him of his labour, and to take upon them a thousand burdens. They are born to carry, to walk, to supply man’s weakness, and to obey all his motions. Oxen are endowed with strength and patience, in order to draw the plough and till the ground. Cows yield streams of milk. Sheep have in their fleeces a superfluity which is not for them, and which still grows and renews, as it were to invite men to shear them every year. Even goats furnish man with a long hair, for which they have no use, and of which he makes stuffs to cover himself. The skins of some beasts supply men with the finest and best linings, in the countries that are most remote from the sun.
Thus the Author of nature has clothed beasts according to their necessities; and their spoils serve afterwards to clothe men, and keep them warm in those frozen climes. The living creatures that have little or no hair have a very thick and very hard skin, like scales; others have even scales that cover one another, as tiles on the top of a house, and which either open or shut, as it best suits with the living creature, either to extend itself or shrink. These skins and scales serve the necessities of men: and thus in nature, not only plants but animals also are made for our use. Wild beasts themselves either grow tame or, at least, are afraid of man. If all countries were peopled and governed as they ought to be, there would not be anywhere beasts should attack men. For no wild beasts would be found but in remote forests, and they would be preserved in order to exercise the courage, strength, and dexterity of mankind, by a sport that should represent war; so that there never would be any occasion for real wars among nations. But observe that living creatures that are noxious to man are the least teeming, and that the most useful multiply most. There are, beyond comparison, more oxen and sheep killed than bears or wolves; and nevertheless the number of bears and wolves is infinitely less than that of oxen and sheep still on earth. Observe likewise, with Cicero, that the females of every species have a number of teats proportioned to that of the young ones they generally bring forth. The more young they bear, with the more milk-springs has nature supplied them, to suckle them.
While sheep let their wool grow for our use, silk-worms, in emulation with each other, spin rich stuffs and spend themselves to bestow them upon us. They make of their cod a kind of tomb, and shutting up themselves in their own work, they are new-born under another figure, in order to perpetuate themselves. On the other hand, the bees carefully suck and gather the juice of odorous and fragrant flowers, in order to make their honey; and range it in such an order as may serve for a pattern to men. Several insects are transformed, sometimes into flies, sometimes into worms, or maggots. If one should think such insects useless, let him consider that what makes a part of the great spectacle of the universe, and contributes to its variety, is not altogether useless to sedate and contemplative men. What can be more noble, and more magnificent, than that great number of commonwealths of living creatures so well governed, and every species of which has a different frame from the other? Everything shows how much the skill and workmanship of the artificer surpasses the vile matter he has worked upon. Every living creature, nay even gnats, appear wonderful to me. If one finds them troublesome, he ought to consider that it is necessary that some anxiety and pain be mixed with man’s conveniences: for if nothing should moderate his pleasures, and exercise his patience, he would either grow soft and effeminate, or forget himself.
SECT. XX. Admirable Order in which all the Bodies that make up the Universe are ranged.
Let us now consider the wonders that shine equally both in the largest and the smallest bodies. On the one side, I see the sun so many thousand times bigger than the earth; I see him circulating in a space, in comparison of which he is himself but a bright atom. I see other stars, perhaps still bigger than he, that roll in other regions, still farther distant from us. Beyond those regions, which escape all measure, I still confusedly perceive other stars, which can neither be counted nor distinguished. The earth, on which I stand, is but one point, in proportion to the whole, in which no bound can ever be found. The whole is so well put together, that not one single atom can be put out of its place without unhinging this immense machine; and it moves in such excellent order that its very motion perpetuates its variety and perfection. Sure it must be the hand of a being that does everything without any trouble that still keeps steady, and governs this great work for so many ages; and whose fingers play with the universe, to speak with the Scripture.
SECT. XXI. Wonders of the Infinitely Little.
On the other hand the work is no less to be admired in little than in great: for I find as well in little as in great a kind of infinite that astonishes me. It surpasses my imagination to find in a hand-worm, as one does in an elephant or whale, limbs perfectly well organised; a head, a body, legs, and feet, as distinct and as well formed as those of the biggest animals. There are in every part of those living atoms, muscles, nerves, veins, arteries, blood; and in that blood ramous particles and humours; in these humours some drops that are themselves composed of several particles: nor can one ever stop in the discussion of this infinite composition of so infinite a whole.
The microscope discovers to us in every object as it were a thousand other objects that had escaped our notice. But how many other objects are there in every object discovered by the microscope which the microscope itself cannot discover? What should not we see if we could still subtilise and improve more and more the instruments that help out weak and dull sight? Let us supply by our imagination what our eyes are defective in; and let our fancy itself be a kind of microscope, and represent to us in every atom a thousand new and invisible worlds: but it will never be able incessantly to paint to us new discoveries in little bodies; it will be tired, and forced at last to stop, and sink, leaving in the smallest organ of a body a thousand wonders undiscovered.
