c. The third trope turns on the difference in the constitution of the organs of sense as related to one another; _e.g._ in a picture something appears raised to the eye but not to the touch, to which it is smooth, &c.[199] This is, properly speaking, a subordinate trope, for in fact a determination such as this coming through some sense, does not constitute the truth of the thing, what it is in itself. The consciousness is required that the unthinking description which ascribes existence to blue, square, &c., one after the other, does not exhaust and express the Being of the thing; they are only predicates which do not express the thing as subject. It is always important to keep in mind that the different senses grasp the same thing in contradictory ways, for by this the nullity of sensuous certainty is revealed. d. The fourth trope deals with the diversitude of circumstances in the subject, in reference to its condition, the changes taking place in it, which must prevent our making an assertion respecting any particular thing. The same thing manifests itself differently to the same man, according as he, for instance, is at rest or moving, asleep or awake, moved by hatred or love, sober or drunk, young or old, &c. In the diversitude of these circumstances very different judgments are passed regarding one and the same object, hence we must not talk of anything as being more than a manifestation.[200] e. The fifth trope relates to the different positions, distances and places, for from every different standpoint the object appears to be different. In respect to position, a long passage appears to the man who stands at the one end to taper to a point at the other; but if he goes there he finds it to be of the same breadth at that end as it was at the other. Distance is likewise, properly speaking, a difference in the greatness and smallness of objects. In respect to place, the light in a lantern is quite feeble in the sunshine, and yet in darkness it shines quite brightly. Pigeons’ necks, regarded from different points of view, shimmer quite differently.[201] In regard to motion in particular very different views prevail. The best known example of such is found in the course of the sun round the earth, or the earth round the sun. As the earth is said to go round the sun, even though the opposite appears to be the case, the former assertion is based on reasons. This example does not, however, come in here, but this trope will show that because one sensuous feeling contradicts another, existence is not expressed in it.
