 Among recent objections to Vision in God, one of the most important concerns the relation of intelligible extension to sensations. As we have seen, Malebranche draws an important distinction between these but also thinks that sense perception combines elements of each. To the sensory component Malebranche accords a crucial role in explaining how intelligible extension is ‘particularized’ or individuated, so as to represent a material object in the world. Sensations of color and light, he says, are ‘projected’ or ‘painted’ onto intelligible extension as if it were an artist’s canvas. The problem, however, is in understanding how these radically disparate entities – ideas and sensations – can have any commerce with each other. Even if we reject the reading that ideas are logical entities, they are nevertheless general and pure, and thus different in kind from sensations.
