[Consider the catch phrase:] “It may be true for you, but it’s not true for
me.” What is the meaning of the concept “truth”? Truth is the recognition of
reality. (This is known as the correspondence theory of truth.) The same thing
cannot be true and untrue at the same time and in the same respect. That catch
phrase, therefore, means: a. that the Law of Identity is invalid; b. that there
is no objectively perceivable reality, only some indeterminate flux which is
nothing in particular, i.e., that there is no reality (in which case, there can
be no such thing as truth); or c. that the two debaters perceive two different
universes (in which case, no debate is possible). (The purpose of the catch
phrase is the destruction of objectivity.)
