=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]. [Sidenote: Cohesion.] =207.= Lowest in the scale come inanimate objects, such as stones[102]. Yet even these have a property which corresponds to soul, and which keeps them together in a particular outward form or shape; this property we call ‘cohesion’ (ἕξις, _unitas_)[103]; like soul itself, it is a spirit pervading the whole[104], and again it is the Logos of the whole. An external force cannot impart this unity: so that the water contained in a glass is not an ‘inanimate object’ in this sense[105]. In this lowest grade of ‘spirit’ we read in Stoicism the antithesis of the materialism of Epicurus, who postulates for his ‘atoms’ the fundamental property of indivisibility, and can only account for the coherence of the bodies formed from them by supplying them with an elaborate system of ‘hooks and eyes,’ which was a frequent subject of derision to his critics. Epicurus makes the indivisibility of the smallest thing his starting-point, and from it constructs by degrees a compacted universe by arithmetical combination; the Stoics start from the indivisibility of the great whole, and working downwards explain its parts by a gradual shedding of primitive force. God is in fact in the stone by virtue of his power of universal penetration (κρᾶσις δι’ ὅλων)[106]. [Sidenote: Gradations of spirit.]
