  Conscious mental states are typically regarded as having a representational or intentional aspect in so far as they are about things, refer to things or have satisfaction conditions. One's conscious visual experience correctly represents the world if there are lilacs in a white vase on the table (pace Travis 2004), one's conscious memory is of the attack on the World Trade Center, and one's conscious desire is for a glass of cold water. However, nonconscious states can also exhibit intentionality in such ways, and it is important to understand the ways in which the representational aspects of conscious states resemble and differ from those of nonconscious states (Carruthers 2000). Searle (1990) offers a contrary view according to which only conscious states and dispositions to have conscious states can be genuinely intentional, but most theorists regard intentionality as extending widely into the unconscious domain.
