 Another long-standing interpretation, the Direct Realist interpretation, says that for Descartes the objects immediately represented or presented to the mind (by way of an idea) are not always mental objects. (Nadler 1989) The idea of the Sun is understood as being a mental operation (a mode of the mind) directed at the Sun itself. In fact, on this interpretation, all ideas are, properly speaking, to be understood as operations or acts of the mind. This holds even for the idea of Pegasus. The idea is a mental operation and in this case is directed at the mentally fabricated object, Pegasus. Here, Pegasus is a purely mental object. By contrast, the (sensory) idea of the Sun is directed at the Sun itself, the Sun in the heavens. Thus, this interpretation allows ideas to be directed at mental and extra-mental objects. The import of this interpretation is that the immediate objects of awareness need not be purely mental—so, no tertium quid—which differs dramatically from the Representationalist interpretation. Although both readings have their merits, the remainder of this entry will work within the framework of the Representationalist reading.
