Forgive me if this question is clumsily posed.
The so-called 'Copernican revolution' of declaring the mind as bringing objecthood and properties to objects, rather than their perception bringing those properties to mind, strikes me in its implication as rather similar to the concept of language as a series of language games.
For one neccessarily does not entail in one's conception of an object the full semantic weight of that object, and so, in projecting this upon the object when perceived, what one perceives is therefore in some sense arbitrary (that is to say veridically flexible, because at the very least one may add more to one's conception of the meaning of the object) suggesting an isolation from the necessarily inaccessible object-in-itself- and so related to the object by useful convention of the self, just as words in their usage relate to referents by useful convention of a dialogue.
Is this sort of framing of the Copernican principle sound? Has it been expounded before? Is it even consistent?
