To lie is the absolute form of evil. To lie a little is not possible: he who lies, lies the whole lie. To lie is the very face of the demon.

Context

“The Abbé Sicard speaks of Sister Simplice in a letter to the deaf-mute Massieu. However pure and sincere we may be, we all bear upon our candor the crack of the little, innocent lie. She did not. Little lie, innocent lie—does such a thing exist? To lie is the absolute form of evil. To lie a little is not possible: he who lies, lies the whole lie. To lie is the very face of the demon. Satan has two names; he is called Satan and Lying. That is what she thought; and as she thought, so she did. The result was the whiteness which we have mentioned—a whiteness which covered even her lips and her eyes with radiance.” source
