controlled by its outlying or superior one, and hence it follows that the earth, which is thus disturbed by the conspiring or conflicting action of all above it, is liable to the most irregularities; that, since animals are nourished by the earth, it needs must enter into their composition, but that water is required to hold the earthy matters together; that every element must be looked upon as living, since it is pervaded by the soul of the world; that there is an unbroken chain from the simple element through the plant and animal up to man, the different groups merging by insensible shades into one another: thus zoophytes partake partly of the vegetable and partly of the animal, and serve as an intermedium between them; that plants are inferior to animals in this, that they do not possess a single principle of life or soul, but many subordinate ones, as is shown by the circumstance that, when they are cut to pieces, each piece is capable of perfect or independent growth or life. Their inferiority is likewise betrayed by their belonging especially to the earth to which they are rooted, each root being a true mouth; and this again displays their lowly position, for the place of the mouth is ever an indication of the grade of a creature: thus in man, who is at the head of the scale, it is in the upper part of the body; that in proportion to the heat of an animal is its grade higher; thus those that are aquatic are cold, and therefore of very little intelligence, and the same maybe said of plants; but of man, whose warmth is very great, the soul is much more excellent; that the possession of locomotion by an organism always implies the possession of sensation; that the senses of taste and touch indicate the qualities of things in contact with the organs of the animal, but that those of smell, hearing, and sight extend the sphere of its existence, and indicate to it what is at a distance: that the place of reception of the various sensations is the soul, from which issue forth the motions; that the blood, as the general element of nutrition, is essential to the support of the body, though insensible itself: it is also essential to the activity of the soul; that the brain is not the recipient of sensations: that function belongs to the heart; all the animal activities are united in the last; it contains the principle of life, being the principle of motion: it is the first part to be formed and the last to die; that the brain is a mere appendix to the heart, since it is formed after the heart, is the coldest of the organs and is devoid of blood; that the soul is the reunion of all the functions of the body: it is an energy or active essence; being neither body nor magnitude, it cannot have extension, for thought has no parts, nor can it be said to move in space; it is as a sailor, who is motionless in a ship which is moving; that, in the origin of the organism, the male furnishes the soul
