2389. The lower animals therefore, as the Fishes, have almost nothing but intermaxillary and palatal teeth. They act principally upon the lingual teeth. The reptiles have still palatal teeth, which higher up in the vertebrate series disappear.
Symmetry.
2390. As the cervical ribs have nothing more to inclose, have no longer to respire, but only to move; their symmetrical development is thus undelayed. The symmetry is at first wholly attained by the act of opening or apertion.
2391. The limbs are the most symmetrical organs. They are symmetrical in each smallest part, and these parts again assume a symmetrical arrangement in regard to each other. They are the ideal of symmetry.
2392. They are, however, the free living symmetry. They can create by their motions symmetrical forms. The symmetry consists chiefly in, and has been produced only by, the motion.
2393. The symmetry of the motion is the most exalted, for it is that which is endowed with life. The symmetry of the form is that which is dead.
2394. The symmetry of the form appertains to inorganic nature, the symmetry of the motion is the property of animals.
2395. Dancing and acting are the highest organic symmetrical movements, and also the highest symmetries. They are the symmetry of the motor members, wrought by motion.
2396. Music is a much higher symmetry of motion.
2397. Speech is the highest spiritual symmetry; it is the dance and histrionism of the spirit or mind.
