I consider, then, that the position of our minds, as far as they are uncultivated, towards intellectual objects,—I mean of our minds, before they have been disciplined and formed by the action of our reason upon them,—is analogous to that of a blind man towards the objects of vision, at the moment when eyes are for the first time given to him by the skill of the operator. Then the multitude of things, which present themselves to the sight under a multiplicity of shapes and hues, pour in upon him from the external world all at once, and are at first nothing else but lines and colours, without mutual connection, dependence, or contrast, without order or principle, without drift or meaning, and like the wrong side of a piece of tapestry or carpet. By degrees, by the sense of touch, by reaching out the hands, by walking into this maze of colours, by turning round in it, by accepting the principle of perspective, by the various slow teaching of experience, the first information of the sight is corrected, and what was an unintelligible wilderness becomes a landscape or a scene, and is understood to consist of space, and of bodies variously located in space, with such consequences as thence necessarily follow. The knowledge is at length gained of things or objects, and of their relation to each other; and it is a kind of knowledge, as is plain, which is forced upon us all from infancy, as to the blind on their first seeing, by the testimony of our other senses, and by the very necessity of supporting life; so that even the brute animals have been gifted with the faculty of acquiring it.
John Henry Newman, Idea of a University 2.9.6
