In prior posts (here and here), I have illustrated representational methods and direct methods. The illustrations were from science, because that is more public so easier to demonstrate the contrast. I believe that they illustrate well enough, the distinction between direct and indirect perception. Both aim to provide the same sort of information about the world. The method is different, though perhaps the differences are small enough to be confusing.
The primary distinction here is that direct perception is simpler and more direct, and does not rely on computation or inference. This is why I see direct perception as more likely to be what has evolved, and thus a more likely candidate for explaining human perception.
One way of seeing the distinction is to look at it in terms of categorization. Here, I use “categorization” to refer to the dividing up of the world into parts (or categories). This comes from the old idea (from Plato?) of carving the world at its seams, though the seams might actually be man-made.
