Is There a Difference Between Theory and Reality?

Marshall McLuhan said for the romantic mind theory was not something abstracted from experience and separate from it Based on a presentation, but presence in the active perception. Fact and theory like particular universal were not opposites They are not only intimately connected but interpenetrate each other And the particular represents the universal so as far as I'm concerned I this is why a later revisiting would be so valuable because God help me I could be wrong, but I have a feeling that what Marshall McLuhan writes about with the medium is the same damn thing.
