 Arnauld says that the object of any perception has objective being in the perception. Furthermore, the object has objective being in the perception as having properties. If an object exists objectively in a given perception as having a given property, then Arnauld says that the perception represents the object as having that property, that is, makes the object present to the mind as having that  property.[4]  Furthermore, an idea (or perception) can represent its object to the perceiving mind as having this or that property contingently or necessarily. Arnauld cites the dictum, “it is in the idea of each thing that we see its properties,” and takes it to refer to an explicit reflection upon an idea that represents its object as having certain properties necessarily.
