(See the article on Vision, in the Encyclopædia Britannica, 11th Edition).
The effect of the ingenious device employed in the realistiscope is to modify the light rays transmitted by the pictures, so as to make them resemble those which emanate from the original object. Hence, when the image from such modified rays is formed on the retina, mind, guided by the resemblance between the realistiscopic excitation and that from the normal object, operates upon it in its usual way, thus, projecting into the external space the mental image of a life-sized object capable of being the original cause of the sensation actually felt.
Concerning the power of mind to project these mental images in the external space, Schopenhauer observes :
“If seeing consisted in mere sensation, we should perceive the impression of the object turned upside down, because we receive it thus; but in that case, we should perceive it as something within our eye, for we should stop short at the sensation. In reality, however, the understanding steps in at once with its causal law, and as it has received from sensation the datum of the direction in which the ray impinged upon the retina, it pursues that direction retrogressively up to the cause on both lines; so that this time the crossing takes place in the opposite direction, and the cause presents itself upright as an external object in space, i.e., in the position in which it originally sent forth its rays, not that in which they reached the retina." *
The localization of the object is determined by the
