¶1176.
- To injure truth by a lie is always wrong. Yet truth itself is not to be manifested inopportunely, lest we harm ourselves or others. Therefore, with discretion persuading, sometimes we can permit the error of our neighbor by using mental restriction. Moreover, truth often must be altogether kept silent, as often namely as it has become known to us under the law of secrecy. Hence we shall speak: 1. of lying; 2. of mental restriction; 3. of violation of secrecy.
