|Geach I 197
Implication/GeachVsReichenbach: "Quasi-implication" is scientifically useless because we can only know pJq when we know that q "holds" - ("holds": not assertible, not true). - Reichenbach: "when the measurement M is performed, the device will display the value q1." - GeachVs: that is scientifically useless - it is also an absurd result: "When the measurement is performed, the measurement is performed" is here not a tautology. - Geach: But even non-truth-functional repetitions are tautologies.
