My design is to shew the manner wherein we perceive by Sight the Distance, Magnitude, and Situation of objects; also to consider the difference there is betwixt the ideas of Sight and Touch, and whether there be any idea common to both senses 1. 2. It is, I think, agreed by all that Distance of itself, and immediately, cannot be seen. For, distance being a line directed endwise to the eye, it projects only one point in the fund of the eye--which point remains invariably the same, whether the distance be longer or shorter 2. 1 The design of this Essay is, to compare the phenomena presented in Sight and in Touch, and to shew how we learn to see the primai-y or mathematical qualities of things. But we are led to consider the office of all the Five Senses in the formation of knowledge, in the course of this analysis of Sight, 'the most perfect and delightful' of them all. 2 Sect. 2-51 explain how we learn to 'see' Distance, or an interval between two visible points. (Of. Vindication, sect. 62-69.) Sect. 2 takes for granted, but without distinct proof, that distance is necessarily invisible. It must be noted that the 'distance' of which this can be assumed is space in its third dimension--depth or thickness; not space merely as plane superficial extension. In relation to the distance which Berkeley says cannot be seen--that which is in the line of sight, the percipient is at the end of a straight line, the interval between the two points of which must, it is argued, be invisible, because only one of them can be seen. When we see superficial distance, on the other hand, we are at the side, and not at the end of the line--at a point where it forms a larger or smaller angle with the eye; so that this...
