An Essay Towards a New Theory of VisionForming a triangle of British empiricism with Locke and Hume, George Berkeley's direct influence on modern thought cannot be overstated. From the American Founding Fathers, who looked to him as the pioneer of their idealism, to the reality-questioning motives of quantum physics, Berkeley's odd yet profound view of the nature of human awareness, a sense he trusted implicitly, has in turn shaped our perception of the universe at large. His 1709 "Essay Towards a New Theory of Vision" reads like the ramblings of a madman-and he was, in fact, dismissed as such in his time-but his discussion of perception, distance, parallelism, magnitude, and other elements of vision, presented as 160 suppositions, is now recognized as a foundational work on the theory of optics. This strange work will intrigue readers of philosophy and scientific theory. Irish scientist, philosopher, and writer GEORGE BERKELEY (1685-1753) also wrote A Treatise Concerning the Principles of Human Knowledge (1710) and Three Dialogues Between Hylas and Philonous (1713). |

of those distances, in respect of which the breadth of the PUPIL hath any sensible
bigness: And that is the greater or lesser divergency of the rays, which issuing ...

No man, I believe, will pretend to see or feel those imaginary angles that the rays
are supposed to form according to their various inclinations on his eye. But he
cannot choose seeing whether the OBJECT appear more or less confused.

Before the double convex glass or concave speculum EBF, let the point A be
placed at such a distance that the rays proceeding from A, after refraction or
reflection, be brought to unite somewhere in the AxAB. And suppose the point of

1 the rays falling nearly parallel on the eye, are by the crystalline AB refracted, so
as their focus or point of union F falls exactly on the retina: but if the rays fall
sensibly diverging on the eye, as in Fig. 2, then their focus falls beyond the retina:

appearance, and this confusedness being greater or lesser to the naked eye,
according as the object is seen by rays more or less diverging, it follows that a
