Student: The publications of Professor Vallejo on the origins of glassblowing have reopened the debate among historians over whether glassblowing originated in Egypt or elsewhere. ██ █████████ ███████ ██ ████████ █████ ██ ████████████ ████████ ███ █████████ ██ ████ ██████████ ████ ████ ███ ████ ██████ ████ ████████████ █████ ██ ██████ ███ ███████ ███ ████ ████ ███ ███████████ ████ ██ █████ ██████████ ██ ███ ████████ ██ ███████████ ██ █████████ ███████ ██ ████████ ██ ████ ████████ ████ ████████████ ██████████ ██████████
The author concludes that if Professor V is correct, glassblowing originated outside of Egypt. This is based on a premise that establishes if Professor V is correct, there’s not enough evidence for the claim that glassblowing began in Egypt.
The author assumes that lack of sufficient evidence for a claim’s truth implies that the claim is false. This overlooks the possibility that a claim can still be true (glassblowing originated in Egypt) even if we don’t have enough evidence to prove that it’s true.
