 Some logicians object to ex falso quodlibet, on the ground that the sentence \(\psi\) may be irrelevant to any of the premises in \(\Gamma\). Suppose, for example, that one starts with some premises \(\Gamma\) about human nature and facts about certain people, and then deduces both the sentence “Clinton had extra-marital sexual relations” and “Clinton did not have extra-marital sexual relations”. One can perhaps conclude that there is something wrong with the premises \(\Gamma\). But should we be allowed to then deduce anything at all from \(\Gamma\)? Should we be allowed to deduce “The economy is sound”?
