reveal it, we are unable to see the principle of Life everywhere shine freely through it; it remains _only_ an _inwardness_, and the shell is _external only_ unpermeated by the vital principle. (_b_) The _human_ body, in virtue of its more exalted station, presents us with a striking contrast. In this we are everywhere reminded that man is in possession of a unity of feeling, a soul. The human skin is not covered over plant-like with an apparently lifeless sheath; the pulsation of the blood is visible throughout the entire surface; the beating heart of life is everywhere at the same time apparent; and we have in this outward manifestation, as it were, the real fount Of life made visible, the _turgor vitae_ as it streams from its centre. In the same way the human skin, sensitive throughout in its minutest parts, reveals to us the _morbidezza_ of its colouring, those tints of flesh-colour and vein-colour which are the despair of an artist. On the other hand, however much the human body presents, as the apparent mirror of Life, a contrast with that of animals, it undoubtedly expresses also the natural process of self-preservation in the subdivision of the skin, and the indentations, wrinkles, pores, small hairs and veins which we find attach thereto. In fact the skin itself, though permitting the inner life to shine through it, is none the less an external protection of that life, a means obviously intended for such self-preservation. The supreme significance, however, of the contrast here presented is traceable in this extraordinary sensitiveness of the human cuticle, which, although not absolutely the seat of feeling itself, alone renders such feeling possible. But at the same time even in this direction we are made conscious of the defect, that this sensitiveness does not penetrate as a vital impulse of concentrated emphasis equally through all the members. We find in the human body itself certain organs whose form is entirely appropriate to mere animal functions, while others give a more adequate expression to the entire soul-life, its feelings and passions. Regarded in this way it is obvious that even in the human body the inner life of soul has not found its complete reflection in all parts of its external realization.
