Abstract

The representative theory of perception is one of the realist theories of perception which maintains we do not have direct access to the objects of perception; our ideas represent some objective objects in the world. In this paper, I will address the question about the representative nature of mental ideas from a Thomistic perspective. I will explore if some Thomists are entitled to claim that Aquinas’ theory of knowledge based on his metaphysics can provide a basis for resolving this issue. I will argue that this question is wrong-headed and it should be replaced with the following question: If we assume the existence of a real world and that we are not under the influence of hallucination, how we can know that our ideas truly represent the world?
