Nescire autem quid antequam natus sis acciderit, id est semper esse puerum. (To be ignorant of what occurred before you were born is to remain always a child.)

Cicero offers this maxim in his dialogue *Orator* (46 BCE), written late in his career amid the political upheavals following Caesar’s rise. In the work he defends an ideal of the “perfect orator,” arguing that true eloquence requires broad learning—especially knowledge of history—because public speech and statesmanship depend on understanding human affairs over time. The line appears as part of a claim that history is essential to mature judgment: without awareness of what happened before one’s birth, a person lacks the perspective that forms an adult mind and remains intellectually immature.

The sentence equates historical ignorance with perpetual childhood. Cicero’s point is not merely that facts about the past are useful, but that memory of earlier events enlarges one’s moral and civic understanding: it supplies examples, cautions, and a sense of continuity that disciplines judgment. “Always a child” implies dependence on immediate impressions and susceptibility to manipulation—failings especially dangerous in public life. The remark also reflects a Roman educational ideal in which history trains character and prudence. In modern terms, Cicero argues that historical consciousness is a prerequisite for intellectual adulthood and responsible citizenship.

1) “To be ignorant of what happened before you were born is to remain forever a child.”
2) “Not to know what has been transacted in former times is to be always a child.”
3) “He who knows nothing of what happened before he was born will always remain a child.”
