No. You don't get to play weenie semantic games like some first year philosophy major, and try to deflect.
Express your truth in words, math, or colored beads. It doesn't matter. You still have to build the box within which you are defining your "truth", because - as I demonstrated - there is no empirical truth which exists in some fictional pure state. "Truth" is a measurement against something else, not a base principle.
Even mathematicians begin with, "assume an infinite plane" before they move on to their mathematical proof. Truth is a point defined within a box of context.
Want proof? Find a single base truth that is true in every context. You can't. It's just that simple.
