No, it doesn't dissolve it, it dodges it. Meanings are not elsewhere in the sense that they are basic to the process of analysis of any kind of question whatever.

The problem I see with what you're saying in this thread is that you're talking about cognitive science, not philosophy. Your 'direct realism' simply takes for granted the reality of objects of perception, and then asks questions about how the sensory organs process them.
