27. If the earth communicate to plant-life the power of begetting and growing, it possesses this power within itself, and gives only a trace of it to the plants which derive from it all their fruitfulness, and as it were are the living flesh of its body. It gives to them what is best in them; this can be seen in the difference between a plant growing in the soil, and of a branch cut from it; the former is a real plant, the latter is only a piece of wood. What is communicated to the body of the earth by the Soul which presides over it? To see this it is sufficient to notice the difference between some earth resting within the soil, and a piece that is detached therefrom. It is likewise easy to recognize that stones increase in size as long as they are in the bosom of the earth, while they remain in the same state when they have been plucked out therefrom. Everything therefore bears within itself a trace of the universal vegetative (power) shed abroad over the whole earth, and belonging particularly to no one of its parts. As to the earth's power of sensation, it is not (like its vegetative power) mingled with the body of the earth; it only hovers above and guides it. Moreover, the earth possesses also, higher than the above powers, a soul and an intelligence. They bear respectively the names of Ceres and Vesta, according to the revelations of men of prophetic nature, who allow themselves to be inspired by the divine. DOES THE IRASCIBLE POWER ALSO ORIGINATE IN THE BODY? 28. Enough of this. Let us return to the question from which we digressed. We granted that the desires, pains and pleasures (considered not only as sentiments, but as passions), originate in the constitution of the organized and living body. Must the same origin be assigned to the irascible (power)? Were this so, we would have several questions to ask: Does anger belong to the entire organism, or only to a particular organ, such as the heart when so disposed, or to the bile, as long as it is part of a living body? Is anger different from the principle which gives the body a trace of the soul, or is it an individual power, which depends on no other power, whether irascible or sensitive? THE LIVER IS THE SEAT OF THE SOUL'S FACULTY OF DESIRE. The vegetative power present in the whole body communicates to every part thereof a trace of the soul. It is therefore to the entire body that we must refer suffering, pleasure, and the desire of food. Though nothing definite is ascertained about the seat of sexual desire, let us grant that their seat is in the organs destined to its satisfaction. Further, be it granted that the liver is the seat of the soul's faculty of desire, because that organ is particularly the theatre of the activities of the vegetative power which impresses a trace of the soul on the body; and further, because it is from the liver that the action it exercises starts. THE HEART IS THE SEAT OF ANGER.
