To Derrick.

Sorry I never replied to your question of whether I should not count a sense perception as re-presentation, since it was earlier presented to the retina. (This thread is so long now that one can easily miss bits of it.) What causes the retinal image is not "presented" to a conscious perceiver, so no, it has not been earlier presented to any mind.I have no access to my retinal images.
I also apologize for misnumbering the step in your argument which referred to mental representations. It was step 4, not step 3. I still think that sense perceptions should not be put on the same level as real re-presentations (or of pre-presentations) since they are as direct as we get to what is happening around us, even if that is ever so slightly out of date. Thanks for the stimulus, Annette Baier.
