 But the Condillac of the Essay was not impressed by these considerations. Though he admitted that the image imprinted by light on the eye is merely two-dimensional, he denied that the mind must therefore only be aware of a two-dimensional image (Essay I.vi §2). However he had little to say about how the mind might acquire information about outward distances, and instead confined himself to attacking the standard  account.[2]  On the standard account, when I perceive a three dimensional object, such as a uniformly coloured globe, I must really see a two dimensional projection of that object, variously shaded in its different parts, and then judge that this two-dimensional, variously coloured image is a representation of a uniformly coloured three-dimensional object (the classic presentation of this view is to be found in Locke’s Essay, book II, chapter ix, paragraph 8). But I am not conscious of seeing a flat, variously coloured circle, nor am I conscious of making a judgment about what this image represents. Instead, I seem to immediately see a uniformly coloured, three-dimensional object. Moreover, try as I might, I cannot make myself aware of drawing an inference. And I have so little awareness of the flat, variously coloured circle that I supposedly see that, without the aid of instruction in drawing or painting, I would have no idea that it bears any relation to a uniformly coloured globe. Condillac found this insupportable. The mind, he maintained, cannot be so deeply ignorant of what it senses or of what it does (Essay I.vi §§3–5).
