Note 53 — Chapter XIX · IMPLICATION

Irrelevant in a popular sense; one would not say, speaking loosely, that the fact that Brutus killed Cæsar implies that the sea is salt; and yet this conclusion is implied both by the above premiss, and the premiss that Cæsar killed Brutus. Cf. on such questions Venn, S. L., 2nd ed., pp. 240-4.
