“… a lying tongue is a man's destruction.” – The Wisdom of Solomon, 1.11
When I was ten years old, I happily discovered that I could say whatever I wanted in response to a question without lying. If my mother asked me if I had cleaned my room, I could say, “Yes, mother” – because she didn't ask whether I had cleaned it today. Or even if she had thought to ask whether I had cleaned my room today, I could still say “Yes, mother” – because she didn't ask if I had cleaned all of my room today (and surely I had managed to put at least one little thing away). And so on. To the extent I had any theory about it, I thought that I couldn't be accused of lying if other people hadn't taken the trouble to ask specific enough questions. At the same time, of course, I knew it was an unreasonable request, and I was in fact being a weasel.
Now imagine my delight in discovering that this golden evasion ticket is not merely a young brat's subterfuge; it is in fact remembered in history as a codified policy of some early Jesuits. Their own need for the policy and their application of it is seen best through an example.
A Jesuit in England in the early 1600s (according to Mario Praz) reportedly swore never to have been a priest, never to have been overseas, and never to have known or even seen a certain William Hawkesworth, who was a suspect in the Gunpowder Plot to assassinate the king. Later, after he had been found out, the priest explained that he had meant that “he had never been a priest of Apollo, he had never been across the Indian sea, never known the said Hawkesworth scientia scientifica [that is, with scientific knowledge], and never seen him in visione beatifica [in a beatific vision]”. The priest's mind had been racing – as we can well imagine – and it was not his problem that the minds of his interlocutors simply had not kept up.
This is an example of what has been known as mental reservation, or honest dissimulation, or (even more colorlessly) non-mendacious linguistic deception, which the philosopher Jonathan Adler defines as “asserting what one believes to be true, inviting the drawing of a conclusion that one believes to be false”.
