De la sincérité envers soi-même

The essay contrasts the easy, social form of honesty shown to others with the riskier task of being honest with oneself, arguing that genuine self-sincerity is an active, demanding practice. Spontaneous feelings are judged unreliable; true inward truth must be hunted, tested and assembled through careful self-examination. The author describes sincerity as a deliberate construction of the soul that requires vigilance, subtlety and repeated effort, and warns that excessive self‑scrutiny can drain naive feeling or provoke crippling doubt. The piece closes by exploring the tension between moral prudence that ignores dangerous impulses and a painstaking interior honesty.
