If then nature, whilst determining the destiny of man, abandons to the will of man himself the care to accomplish it, the relation of his present state with his destiny cannot be a work of nature, but ought to be the work of the person; it follows, that all in the configuration which expresses this relation will belong, not to nature, but to the person, that is to say, will be considered as a personal expression; if then, the architectonic part of his configuration tells us the views that nature proposed to herself in creating him, the mimic part of his face reveals what he has himself done for the accomplishment of these views. It is not then enough for us, when there is question of the form of man, to find in it the expression of humanity in general, or even of that which nature has herself contributed to the individual in particular, in order to realize the human type in it; for he would have that in common with every kind of technical configuration. We expect something more of his face; we desire that it reveal to us at the same time, up to what point man himself, in his liberty, has contributed towards the aim of nature; in other words, we desire that his face bear witness to his character. In the first case we see that nature proposed to create in him a man; but it is in the second case only that we can judge if he has become so in reality. Thus, the face of a man is truly his own only inasmuch as his face is mimic; but also all that is mimic in his face is entirely his own. For, if we suppose the case in which the greatest part, and even the totality, of these mimic features express nothing more than animal sensations or instincts, and, in consequence, would show nothing more than the animal in him, it would still remain that it was in his destiny and in his power to limit, by his liberty, his sensuous nature. The presence of these kinds of traits clearly witness that he has not made use of this faculty. We see by that he has not accomplished his destiny, and in this sense his face is speaking; it is still a moral expression, the same as the non-accomplishment of an act commanded by duty is likewise a sort of action. We must distinguish from these speaking features which are always an expression of the soul, the features non-speaking or dumb, which are exclusively the work of plastic nature, and which it impresses on the human face when it acts independently of all influence of the soul. I call them dumb, because, like incomprehensible figures put there by nature, they are silent upon the character. They mark only distinctive properties attributed by nature to all the kind; and if at times they are sufficient to distinguish the individual, they at least never express anything of the person. These features are by no means devoid of signification for the physiognomies, because the physiognomies not only studies that which man has made of his being, but also that which nature has done for him and against him.
