202. But in the Stoic system this doctrine is overshadowed by the paradox that the universe itself is a rational animal, possessed of free-will and divine. This is the teaching of all the masters of the school, beginning with Zeno himself. It appeared to him to follow logically from two principles, the first that the universe possesses a unity, the second that the whole is greater than its parts. ‘There cannot be a sentient part of a non-sentient whole. But the parts of the universe are sentient; therefore the universe is sentient[74].’ ‘The rational is better than the non-rational. But nothing is better than the universe; therefore the universe is rational[75].’ ‘The universe is one[76]’; we must not therefore think of it as of an army or a family, which comes into a kind of existence merely through the juxtaposition of its members. By the same reasoning the universe possesses divinity[77]. Upon this favourite Stoic text is based the frequent assertion of modern commentators that the philosophy is pantheistic[78]; but the more central position of Stoicism is that the deity bears the same relation to the universe as a man’s soul to his body[79], and the universe is therefore no more all divine than a man is all soul. This view is expressed with great clearness by Varro, who says: ‘As a man is called wise, being wise in mind, though he consists of mind and body; so the world is called God from its soul, though it consists of soul and body[80].’ The Stoics are however in strong conflict with the Epicureans and all philosophers who hold that the world is fundamentally all matter, and that soul and mind are developments from matter. ‘Nothing that is without mind can generate that which possesses mind,’ says Cicero’s Stoic[81], in full opposition to modern popular theories of evolution. Further, just as it may be questioned in the case of man whether the soul is situated in the head or in the heart, so in the case of the universe we may doubt whether its soul, or rather its ‘principate,’ is in the sun, as Cleanthes held[82], or in the sky generally, as Chrysippus and Posidonius maintain[83], or in the aether, as Antipater of Tyre taught[84].

The earth’s inhabitants.

203. In the study of the universe we are not called upon merely to consider the earth as a member of the celestial company; we have to contemplate it as the home of beings of various ranks, which also display to us the principle of orderly arrangement. Preëminent amongst the inhabitants of the earth stands man, who is distinguished by being the sole possessor of the faculty of reason, and in addition owns all those capacities which are shewn in beings of lower rank. The nature of man constitutes so large a part of philosophy that we must reserve its full consideration for a special chapter[85]; and must restrict ourselves here to treating of lower beings, which fall into the three orders of animals, plants, and inanimate beings. But since each of the higher orders possesses all the properties of every order that stands lower, the study of the orders inferior to man is also the study of a large part of human nature. The number and classification of these orders are not to be treated mechanically. From one point of view gods and men form one class, the rational, as opposed to every kind of non-rational being. On the other hand, from the standpoint with which we are rather concerned at this moment, gods, men, and animals are subdivisions of the order of animate beings, below which stand the plants, and lower still things without life. Animals, as the name indicates, possess life or soul; the two lower orders possess something corresponding to soul, but lower in degree. The general term which includes soul in the animal and that which corresponds to it in the plants and in lifeless bodies is ‘spirit’ (πνεῦμα); soul therefore is the highest type of ‘spirit.’

The animals have not reason

204. To the dumb animals the Stoics consistently deny the faculty of reason; and this position must have seemed to them self-evident, since the same word Logos expresses in the Greek both reason and speech. In the Latin the point was no longer so clear; still the words ‘ratio’ and ‘oratio,’ if not identical, appeared to be connected by a natural association. Since the animals then are necessarily unreasoning, those acts of animals which appear to show reason must be explained in some other way. A dog pursues a wild animal by its scent; it must therefore be admitted that in a way the dog recognises that ‘this scent is the sign of the wild animal[86]’; still he is incapable of expressing this belief in the form of a correct syllogism. The industry of the ant is disposed of in a more summary way; this animal shows a ‘restless helplessness,’ climbing up and down straws in meaningless industry; many men however are no wiser[87]. For their young the animals have a certain feeling, yet their grief at losing them is comparatively short-lived[88]. In spite, however, of these limitations the animal world is one part of the wonders of nature, and is deserving of our admiration; all animals have strong affection for their young so long as these need their protection[89], and the dog deserves special recognition both for his keen intelligence and for his loyalty towards his master[90].

but a sort of reason.

205. To define more accurately the nature of animals we must to some extent anticipate the discussion of human nature in a later chapter, which follows the same general lines: for in every point the animals are like men, but inferior. They possess soul, but without reason[91]; by soul we here mean the twin powers of observation and of independent movement[92]. In a rough way the animals also possess a ruling part[93]. Their power of observation enables them to distinguish what is healthful to them from that which is injurious; their power of movement shapes itself into pursuit of the healthful and avoidance of the injurious[94]. They possess also properties which resemble the human feelings, such as anger, confidence, hope, fear; but they do not in a strict sense possess the same feelings as men[95]. As they cannot attain to virtue, neither can they fall into vice[96].

Plant life.

206. From the animals we pass to the plants. These seem to have soul, because they live and die[97]; yet they have not soul in any strict sense of the word. It will therefore be better not to use this word, but to speak of the ‘growth-power’ (φύσις)[98]. The governing part is situated in the root[99]. The growth of plants both in size and in strength is very remarkable, inasmuch as little seeds, which at first find themselves place in crevices, attain such power that they split huge rocks and destroy noble monuments, thus illustrating what is meant by tone or tension; for it is a spirit which starts from the governing part (the root) and spreads to the trunk and branches, conveying a force equally strong to construct and to destroy[100]. From another point of view we may say that the seed contains the Logos or law of the fully developed plant, for under no possible circumstances can any other plant grow from that seed except the plant of its kind[101].
