Non nobis solum (English: Not for ourselves alone) is a Latin motto. A common variation is non nobis, sed omnibus ("not for us, but for everyone"). It means that people should contribute to the general greater good of humanity, apart from their own interests.
The motto is derived from a sentence in Cicero's most influential philosophical work, his treatise On Duties (Latin: De Officiis). In full, Cicero writes, non nobis solum nati sumus ortusque nostri partem patria vindicat, partem amici ("We are not born, we do not live for ourselves alone; our country, our friends, have a share in us"), Cicero de officiis, 1:22. The sentence, as Cicero himself says, is a literal translation of a sentiment from Plato's Letter to Archytas.[1] Cicero associates this concept with the Stoic ideal of cosmopolitanism, according to which all men have a natural kinship with all other men and need to "contribute to the general good by an interchange of acts of kindness (officia), by giving and receiving" (De officiis 1.22, transl. Walter Miller, 1913).
The motto is used by numerous organizations, including schools and military units.
