The eye contains three agents: The optic or visual, the palpebral or pupil, and the eyebrow agent. Each of these has its peculiar sense, and we shall show how they are united.
The optic agent has three direct or convergent glances. The eyes converge toward the object they examine, at such a point that if the object were there they would squint. A skilled observer can determine the distance of the object, upon seeing the two eyes.
There is a revolving or divergent glance. If both eyes project in parallel lines, they see double. A drunken man sees double because the eyes do not converge.
Between these two glances there is the ecstatic or parallel vision; but the object is not so far away that its distance may not be determined. The convergence is not appreciable. This is the dreamy expression. We shall here treat of one only, to which we refer the three others. Let us take the direct glance, passing by the optic agent, since it is direct in all the phenomena we have to consider.
There are three phenomena in the eyebrow: eccentric, concentric and normal. From these we derive nine terms. If the eye is normal, it is a passive expression which determines nothing. If, with the same eye, the eyebrow is eccentric, there is a difference; one part of us tends vehemently toward something, and the other says: "It is not worth the trouble." The sensitive part aspires, while the intellect says, "This amounts to nothing."
The concentric eyebrow indicates a mind disconcerted by fatigue or ennui, a contention of one part of the nature with the other, which resists, and says: "I do not wish to be troubled about this; it wearies me."
The normal brow and the eccentric eye indicate stupor.
Here there is again contrariety. One part of the being ardently aspires toward some object, while the other is powerless to aid it.
The eye is purely an intellectual agent, denoting the various states of the mind.
The eccentric eye and the elevated eyebrow denote vehemence. This is an active state that will become astonishment. Many phenomena will arise and be subordinate to this movement; but it is vehemence par excellence; it is aspiration.
