The sudden and almost uniform judgments which, at a certain age, our minds form of distance, dimension, and situation, make us think that we have only to open our eyes to see in the manner in which we do see. We are deceived; it requires the help of the other senses. If men had only the sense of sight, they would have no means of knowing extent in length, breadth, and depth, and a pure spirit perhaps would not know it, unless God revealed it to him. It is very difficult, in our understanding, to separate the extent of an object from its color. We never see anything but what is extended, and from that we are led to believe that we really see the extent. We can scarcely distinguish in our minds the yellow that we see in a _louis d'or_ from the _louis d'or_ in which we see the yellow. In the same manner, as when we hear the word "_louis d'or_" pronounced, we cannot help attaching the idea of the money to the word which we hear spoken. If all men spoke the same language, we should be always ready to believe in a necessary connection between words and ideas. But all men in fact do possess the same language of imagination. Nature says to them all: When you have seen colors for a certain time, imagination will represent the bodies to which these colors appear attached to all alike. This prompt and summary judgment once attained will be of use to you during your life; for if to estimate the distances, magnitudes, and situations of all that surrounds you, it were necessary to examine the visual angles and rays, you would be dead before you had ascertained whether the things of which you have need were ten paces from you or a hundred thousand leagues, and whether they were of a size of a worm or of a mountain. It would be better to be born blind. We are then, perhaps, very wrong, when we say that our senses deceive us. Every one of our senses performs the function for which it was destined by nature. They mutually aid one another to convey to our minds, through the medium of experience, the measure of knowledge that our being allows. We ask from our senses what they are not made to give us. We would have our eyes acquaint us with solidity, dimension, distance, etc.; but it is necessary for the touch to agree for that purpose with the sight, and that experience should second both. If Father Malebranche had looked at this side of nature, he would perhaps have attributed fewer errors to our senses, which are the only sources of all our ideas. We should not, however, extend this species of metaphysics to every case before us. We should only call it to our aid when the mathematics are insufficient. DIVINITY OF JESUS.
