Diss. III, Equivocal, Ambiguous, and Amphibologi…, Chapter X — The opinion which asserts that words, by common consent of the human commonwealth, signify nothing, when they are employed to conceal a truth which cannot be manifested without grave harm, is rejected as altogether improbable, and false, nn.

Diss. III, Equivocal, Ambiguous, and Amphibologi…, Chapter XIV — The causes why very many more recent writers really defend proscribed purely mental restrictions. Fr.
