I am not sincere even when I am saying that I am not sincere.

This aphoristic self-contradiction is characteristic of Jules Renard’s diary-like writing, where he often records brief, cutting observations about character, vanity, and the difficulty of truthfulness. Renard used such notes to scrutinize his own motives and the performative aspects of social life—how confession can itself become a pose. The line belongs to the tradition of the moralist’s fragment: a compact remark meant less as a stable doctrine than as a moment of self-exposure, capturing the uneasy awareness that even “honesty” can be staged for effect.

The remark is a self-referential paradox: even the claim “I am not sincere” can be a pose, a strategy to appear lucid, modest, or disarming. Renard suggests that sincerity is not simply a matter of intention; it is entangled with self-image and the theatrical nature of speech. By undermining his own confession, he exposes how easily honesty becomes another form of performance. The line also hints at the limits of introspection: the self that speaks cannot fully verify its own truthfulness, because the act of declaring a motive or a state already reshapes it into rhetoric.
