He can think about it, but saying so is not enough. How by your opinion the "nonsense" is defined? Without relevant definition of nonsense you are unable to distinguish between "sense" and "nonsense", thus rendering yourself as incompetent for further discussion, again. A hint 1: such definition isn't a matter of your subjective feeling, but a predicate logic. To call something a "nonsense" isn't so arbitrary game, as you're apparently believing. Hint 2: every statement not containing an implication is a tautology with true value undefined.

So, lets say, we have a following situation: I'm explaining a Pythagorean theorem to my dog. He listens me less or more carefully, but he apparently does not understand it at all. Does it mean, a Pythagorean theorem is a "nonsense"? If not, which other criterion(s) we should apply here?
