It is better to be praised by another than by oneself.

[βέλτερον ὑφ’ ἑτέρου ἢ ὑφ’ ἑαυτοῦ ἐπαινέεσθαι.]

Democritus (c. 460 BC - c. 370 BC) Greek philosopher

Frag. 114 (Diels) [tr. Freeman (1948)]
    (Source)

Original Greek. Diels citation "114. (117 N.) DEMOKRATES. 82." Freeman notes this as one of the Gnômae, from a collection called "Maxims of Democratês," but because Stobaeus quotes many of these as "Maxims of Democritus," they are generally attributed to the latter. The same translation is made by @sentantiq (2016).

Alternate translation: "It is better to be praised by others than by oneself." [tr. Barnes (1987)]
