The childhood shows the man, As morning shows the day.

These lines are commonly attributed to John Milton, but they do not appear in Milton’s poems, prose, or correspondence as preserved in standard editions. The couplet is instead best known as a later aphorism circulating in eighteenth- and nineteenth-century quotation culture, often attached to Milton’s name because its balanced, proverbial style resembles early modern moral verse. It is frequently cited in discussions of education and character formation, where the authority of a major poet lends weight to the sentiment. Because the attribution is doubtful, the safest contextual note is that the saying’s popularity reflects later readers’ interest in linking childhood conduct to adult destiny rather than a clearly documented Miltonic occasion.

The couplet asserts that a person’s adult character is already legible in childhood, just as the quality of a day is often foreshadowed by its morning. It treats early habits, temperament, and moral inclinations as predictive signs rather than trivial preliminaries. The simile also implies continuity: development is not a sudden transformation but an unfolding of what is present from the start. In quotation culture, the lines are often invoked in discussions of education, parenting, and biography to argue that formative years matter decisively—whether as promise, warning, or explanation for later conduct.
