=208.= No existing thing can possess one of the higher grades of spirit without also possessing all the lower. Stones therefore have cohesion, plants growth and cohesion, animals soul growth and cohesion; for these are not different qualities which can be combined by addition, but appearances of the same fundamental quality in varying intensity. Man clearly possesses cohesion, for he has an outward shape; there does not however seem to be any part of him which has merely cohesion. But in the bones, the nails, and the hair are found growth and cohesion only, and these parts grow as the plants do. In the eyes, ears and nose, are sensation, as well as growth and cohesion; that is, there is soul in the sense in which the animals possess soul. It is the intelligence only which in man possesses soul in the highest grade[107]. [Sidenote: The conflagration.] =209.= This universe, in spite of its majesty, beauty and adaptation, in spite of its apparent equipoise and its essential divinity, is destined to perish. ‘Where the parts are perishable, so is the whole; but the parts of the universe are perishable, for they change one into another; therefore the universe is perishable[108].’ Possibly this syllogism would not have appeared so cogent to the Stoics, had they not long before adopted from Heraclitus the impressive belief in the final conflagration, familiar to us from its description in the ‘second epistle of Peter[109].’ According to this theory, the interchange of the elements already described[110] is not evenly balanced, but the upward movement is slightly in excess. In the course of long ages, therefore, all the water will have been converted into air and fire, and the universe will become hot with flame[111]. Then the earth and all upon it will become exhausted for want of moisture, and the heavenly bodies themselves will lose their vitality for want of the exhalations on which they feed. Rivers will cease to flow, the earth will quake, great cities will be swallowed up, star will collide with star. All living things will die, and even the souls of the blest and the gods themselves will once more be absorbed in the fire, which will thus regain its primitive and essential unity[112]. Yet we may not say that the universe dies, for it does not suffer the separation of soul from body[113]. [Sidenote: Is the universe perishable?]
