Representationalism is a philosophical theory that suggests our perception of the world is mediated by mental representations. According to this view, we do not directly experience the external world; instead, we interpret it through images, concepts, or symbols formed in our minds. This means that our understanding of reality is shaped by these internal representations rather than direct interaction with the world itself. In the context of philosophy of mind, representationalism is often discussed in relation to theories of consciousness and perception. It contrasts with direct realism, which posits that we can perceive the world directly as it is. Key figures in this debate include philosophers like René Descartes and David Hume, who explored the nature of perception and reality.
