La clairvoyance “clear vision” is Camus’ word for lucidity

“On the whole, men are more good than bad; that, however, isn’t the real point. But they are more or less ignorant, and it is this that we call vice or virtue; the most incorrigible vice being that of an ignorance that fancies it knows everything and therefore claims for itself the right to kill. The soul of the murderer is blind; and there can be no true goodness nor true love without the utmost clear-sightedness.” (sans toute la clairvoyance possible) ~ Albert Camus from one of the more memorable passages of The Plague, in which he addresses the volunteer sanitary groups put together by citizens to clean the town’s overloaded hospitals.
