Intentionality and consciousness are the fundamental kinds of mental phenomena. Although they are widely regarded as being entirely distinct some philosophers conjecture that they are intimately related. Prominently it has been claimed that consciousness can be best understood in terms of representational facts or properties. Representationalist theories vary in strength. At their core they seek to establish that subjective, phenomenal consciousness (of the kind that involves the having of first-personal points of view or perspectives on the world – perspectives that incorporate experiences with specific phenomenal characters) is either exhausted by, or supervenes on, capacities for mental representation. These proposals face several serious objections.

The ‘received view’ about computation is that all computations must involve representational content. Egan and Piccinini argue against the received view. In this paper, I focus on Egan’s arguments, claiming that they fall short of establishing that computations do not involve representational content. I provide positive arguments explaining why computation has to involve representational content, and how that representational content may be of any type (distal, broad, etc.). I also argue (contra Egan and Fodor) that there is no need for computational psychology to be individualistic. Finally, I draw out a number of consequences for computational individuation, proposing necessary conditions on computational identity and necessary and sufficient conditions on computational I/O equivalence of physical systems.
