Often, the truth of a situation is all in how you look at it.
For example, from a train platform, does it not appear the parallel lines of a railroad track converge at a point near the horizon? But anyone reading this understands that the tracks are not actually converging. What appears to be the truth is actually false: the convergence is a visual illusion. If this is obvious to us today, why did it take mankind until the Renaissance to figure out how to represent this in his art?
