The concept of representation has a vast and highly diverse extension. In this paper I distinguish four kinds of representation, viz. proxy, make-believe, and intentional representation, as well as representation simpliciter. The bulk of the paper is devoted to intentional representation. I argue that the relation of intentional representation is non-reflexive, non-symmetrical, and non-transitive. I articulate a fundamental distinction between two aspects of the content of intentional representations, viz. subject and predicative content. Finally, I qualify and defend the distinction between iconic and symbolic intentional representation. Along the way, I also argue that psychological intentions play a constitutive role in representation.
