The time-lag argument for the representational theory of perception
Hi Jo

Thanks very much for your reply.

You say that you agree that what we directly experience, perceptually, is not the world itself, but that you don't believe that it is a representation/simulation of the world. However, if the content of our perceptions is an experience of the world, but not a direct experience of the world, then doesn't that lead inevitably to the conclusion that what we directly experience, perceptually, is a representation of the world?

You write:
Such an idea is as self contradictory as the direct perception one and modern physics shows empirically that it is invalid.
I don't see how modern physics shows that the conclusion is invalid. Indeed, we know for certain that we do experience mental representations of the world, in the form of memories.

With best wishes
