Welcome to today's installment of Antony Flew vs. Matt Dillahunty.
Antony: "What is true, or false, is propositions. What is valid, or invalid, is arguments. These notions and these distinctions are absolutely basic. To say that an argument is true or that a proposition is valid is as uncomprehending or as inept as to say that someone got to first base in basketball or that someone made a home run in tennis."--How to Think Straight: An Introduction to Critical Reasoning, Antony Flew, Prometheus Books, 1998.
Matt, to caller: "The arguments are either correct or incorrect, independent of who said them, right?"--Atheist Experience, Mar. 12, 2017.
Yikes. As my piano teacher would say, "Ouch!"
