Let us examine this point:

The shoulder, in rising, is not called upon to teach us whether the source of the heat or vehemence which mark it, arise from love or hate. This specification does not lie within its province; it belongs entirely to the face, which is to the shoulder what the barometer is to the thermometer. And it is thus that the shoulder and the face enter into harmonious relations to complete the passional sense which they have to determine mutually and by distinct paths.

Now, the shoulder is limited, in its proper domain, to proving, first, that the emotion expressed by the face is or is not true. Then, afterward, to marking, with mathematical rigor, the degree of intensity to which that emotion rises.

After having finished the formulation of this principle I exultingly exclaimed:

"God be praised! I now possess the semeiotics of the shoulder, and thereby I hold the criterion of the passional or sensitive powers--a criterion outside of which no truth can be demonstrated in the sphere of sentiment or feeling."

Thus, a word suggested by chance became my Archimedean lever. The word, like a flash of light, flooded my mind with radiance which suddenly revealed to me the numerous and fertile applications of a principle hitherto unknown. Yes, I henceforth possessed an æsthetic principle of the utmost value, the consequences of which, I could readily see, were as novel as they were profound.

Episode VI.
First Objection to the Thermometric System of the Shoulder.

The innate æsthetic principle of the semeiotics of the shoulder was at last clearly demonstrated to me, and no more doubt or uncertainty upon that point seemed to me possible. I might safely formulate the following rule:

When a man says to you in interjective form: "I love, I suffer, I am delighted," etc., do not believe him if his shoulder remains in a normal attitude. Do not believe him, no matter what expression his face may assume. Do not believe him--he lies; his shoulder denies his words. That negative form betrays his thoughts; and, if he expresses ardent passion, you have merely to consult the thermometer which, all unwittingly, he himself offers to your inspection. See, it marks zero! therefore he lies; doubt it not, he lies! but his shoulder does not lie. He amiably puts it at your disposal--read, read at your ease; it bears inscribed in living letters his deceit and craft. It can never cheat you, and when the gentleman accosts you with such words as: "Dear friend! how charmed I am to see you!" say to yourself as you look at his thermometer: "Traitor, your delight as well as your friendship is below zero! You try to deceive me, but in vain; henceforth you have no secrets from me, clumsy forger! You do not see, as with one hand you proffer the false jewel which you would sell me, that the other at the same instant gives me the touch-stone which reveals your tricks; your right hand thus incessantly exposing to me the secrets of your left hand!"

What an admirable thing is this mechanism of the body working in the service of the soul! With what precision it reveals the least movements of its master! What magnificent things it lays bare! Voluntarily or involuntarily, everything leads to truth under the action of the translucid light which breaks forth in the working of each of our organs!
