Since this is in the science and philosophy forum, I'm assuming your question is philosophical? Are you looking for a 1:1 correlation between experience and reality? It gets a bit tricky when you put "objective" in front of truth. "Logic is objective" assumes logic to be an objective criteria by which to determine that it is.
"I believe that truth has only one face: that of a violent contradiction."
Sorry if this is unsatisfactory, also I'm not an expert on anything I'm talking about here.
