He hath a good judgment who is apt to distrust his own.

Sound judgment includes recognizing that one’s own conclusions may be mistaken. A person who questions personal certainty is less likely to let pride or haste govern a decision.

The saying commends intellectual humility rather than permanent indecision. Doubting an initial judgment can prompt reconsideration, consultation, and attention to evidence before a choice is treated as final.

Use this proverb, whose archaic “hath” gives it a historical or literary tone, to advise tempering confidence in an opinion or decision when an assumption could matter. It suits reflective discussion of prudence and self-correction, not endless hesitation or distrust of every judgment.
