The mouth is the beginning or, if one prefers, the prow of animals; in the most characteristic cases, it is the most living part, in other words, the most terrifying for neighbouring animals. But man does not have a simple architecture like the beasts, and it is not even possible to say where he begins. In a strict sense, he starts at the top of the skull, but the top of the skull is an insignificant part, incapable of attracting attention and it is the eyes or the forehead the play the significatory role of an animal’s jaws.

Man is the animal whose nature has not yet been fixed.
Among civilized men, the mouth has even lost the relatively prominent character that it still has among primitive men. However, the violent meaning of the mouth is conserved in a latent state: it suddenly regains the upper hand with a literally cannibalistic expression such as mouth of fire, applied to the cannons men employ to kill each other. And on important occasions human life is still bestially concentrated in the mouth: fury makes men grind their teeth, terror and atrocious suffering transform the mouth into the organ of rending screams. On this subject it is easy to observe that the overwhelmed individual throws back his head while frenetically stretching his neck so that the mouth becomes, as far as possible, a prolongation of the spinal column, in other words, it assumes the position in normally occupies in the constitution of animals. As if explosive impulses were to spurt directly out of the body through the mouth, in the form of screams. This fact simultaneously highlights the importance of the mouth in animal physiology or even psychology, and the general importance of the superior or anterior extremity of the body, the orifice of profound physical impulses: equally one sees that a man is able to liberate these impulses in at least two different ways, in the brain or in the mouth, but that as soon as these impulses become violent, he is obliged to resort to the bestial method of liberation. Whence the narrow constipation of a strictly human attitude, the magisterial look of the face with a closed mouth, as beautiful as a safe.
