You're confusing things that exist in themselves and words that describe things that exist. Primary and secondary substances. Individual and universal, specific and general categories of being. This is philosophical metaphysics. Color doesn't exist in itself, does that mean there is no such thing as color? Truth does not exist in itself, does that mean there is such thing as truth? Objectivity doesn't exist in and of itself, does that mean there are no objective things? No. These are words to categorize things. You're confusing the issue and invalidating valid descriptions of reality.
