Moral Theology of the Church of Rome - S. Alfonso De' Liguori's Theory of Truthfulness #227264

We must distinguish between Amphibology or Equivocation, and Mental Restriction. Amphibology can be in three fashions: 1. When a word has two senses, as the word volo means both to wish and tofly. 2. When a sen tence bears two main meanings, as, This book is Peter's, may mean that the book belongs to Peter, or, that Peter is the author of it. 3. When words have two senses one more common than the other, or one literal, the other metaphorical. Thus, if a man is asked about something which it is to his interest to conceal, he can answer, No, I say that 18, I say the word, no. Cardenas doubts about this, but saving his better counsel, he seems to do so without reason, for the word I say really has two senses; it means to utter [make use of a word] and to assert. We here employ it in the sense of utter. — 4. 151.
