According to Maurice Merleau-Ponty, "The blind, says Descartes, “see with their hands.” The Cartesian concept of vision is modeled after the sense of touch." "For Descartes it is unarguably evident that one can paint only existing things, that their existence consists in being extended, and that design, or line drawing, aline makes painting possible by making the representation of extension possible. Thus painting is only an artifice which presents to our eyes a projection similar to that which the things themselves in ordinary perception would and do inscribe in our eyes. A painting makes us see in the same way in which we actually see the thing itself, even though the thing is absent. Especially it makes us see a space where there is none."
The Cartesian system may not lend itself to painting but it most definitely lends itself to architectural drawing. This is an area that needs more research before I can say more.
