If an argument is How the Distinction between Deductive vs. Inductive Arguments Can Mask Uncertainty

The Possibility of Proving the Non-Existence of Something

In a recent blog entry, theistic philosopher William Vallicella criticizes a statement made by psychologist Paul Vitz, in which Vitz asserted that it is “intrinsically impossible” to “prove the non-existence of anything.” As Vallicelli correctly points out: “But surely there are things whose nonexistence can be proven. The nonexistence of a round square can be The Possibility of Proving the Non-Existence of Something
