"Truth isn't truth"-?!

Interesting exchange with my friend Rob Talisse, in wake of Giuliani's "truth isn't truth" Orwellism on Meet the Press. I think Cousin John should get the last word... and Diogenes the Cynic the penultimate:

"You just said 'truth isn't truth!' That's not acceptable from a president's lawyer. It’s barely acceptable from a sophomore philosophy major who just tried molly for the first time." —@iamjohnoliver on Giuliani #LastWeekTonight

“Truth isn’t truth.” OK philosophers, prepare for at least a week of incompetent amateur epistemology from all sides. Starring roles will be played by use/mention errors, confusions of doxastic and propositional justification, and conflations of truth with proof. Gear up!

Important classroom distinctions. But don't lose sight of the bottom line: Drumpf & his minions are lying LIARS.

Of course. Draw crucial distinctions in the extended classroom of serious discourse. But in the polemical arena, don’t blunt the message. Call the liars out.

Impossible to say what lying is (& thus what liars are) without the “classroom” distinctions.
