Wisdom is not attained by years, but by ability.

The saying contrasts mere longevity with genuine discernment: living a long time does not automatically produce wisdom, which instead depends on one’s capacity—judgment, practical intelligence, and the skill to learn from experience. Attributed to Plautus, it fits a common ancient moral theme found in comedy and proverb alike: elders are not necessarily prudent, and the young can be perceptive when they possess talent and good sense. The line’s enduring appeal lies in its challenge to age-based authority and its emphasis on competence as the true measure of insight.

“Wisdom is not gained by age, but by ability.”
“Wisdom comes not with years, but with ability.”
“Wisdom is not acquired by years, but by ability.”
