Document Summary

Obj 3: 3. 11 even if objections 1 and 2 do not prove that sensations are something over and above brain-processes, they do prove that the qualities of sensations are something over and above the qualities of brain-processes. Reply to obj 3: for if they are brain-processes they certainly have properties. I am not sure whether this is so or not, and that is why i regard objection 3 as the strongest with which. One person is more a normal percipient than another if he can make color discriminations that the other cannot. I therefore elucidate colors as powers, in locke"s sense, to evoke certain sorts of discriminatory responses in human beings. They are also, of course, powers to cause sensations in human. Obj 4. : the after-image is not in physical space. Reply to obj 4: not arguing that the after-image is a brain-process, but that the experience of having an after-image is a brain-process.
