logic

In what could not conceivably be otherwise /  by Nathan Jones

“But it is perverse to see tragedy in what could not conceivably be otherwise; and that fact that all empirical statements are contingent, that even when true they can be denied without self-contradiction, is itself a matter of necessity. If empirical statements had the formal validity which makes the truth of logic unassailable they could not do the work that we expect of them; they would not be descriptive of anything that happens.”
— Sir Alfred Ayer in The Problem of Knowledge (1956)
