 In the last section, we learned that there are no particular things in God, but what about particular ideas? Malebranche sometimes writes as if there are, and one commentator has argued that he was committed to such a view in the first edition of the Search (Gueroult 1955–9, vol. 1, 63f). This has since been disputed (see Schmaltz 2000, 72 and note 39), but whatever the case, Malebranche tends in later editions of the Search and in his later writings generally to treat ideas as general and abstract. This is true both of the various geometrical ideas that we see in God and of the idea of extension: ‘when I said that we see different bodies through the knowledge we have of God’s perfections that represent them, I did not exactly mean that there are in God certain particular ideas that represent each body individually …’ (Elucidation 10, OC:154; LO 627). Beginning with the Elucidations, Malebranche employs the term ‘intelligible extension’ to denote the general idea of extension, and to distinguish it from actual extension, which again is unintelligible in itself. In addition to being general, ideas in God are also ‘pure’ in the Cartesian sense that they are non-sensuous. Intelligible extension, then, is just the idea of geometrical extension and its properties, or what in the seventeenth-century came to be known as the ‘primary qualities.’ Malebranche reduces these to two – figure (i.e., size and shape) and motion.
