Dretske on seeing
Reply to Mohan Matthen
The Alston example is really interesting- I thought that if we get rid of
an additional 'conceptual' judgement acting on the content of perceptual experience and treat
the perceptua discriminatoryl experience as non further analysable we won't
treat the case of looking a tomato as a case of an inference from grounds to conclusion. Do U think such a move can be allowed? But then what happens with the Alston example which as U suggest
seems to work best for logical connectives for which U have rules of inference?
Can't we think of a perceptual judgment as one that 'binds' the different sense modalities which is not
'conceptual' and nothing more than that?
