Terence on Caring for Humanity

Terence, a first century mosaic from Mytilene on the island of Lesbos

Homo sum: humani nihil a me alienum puto.

I am a man; and nothing which concerns humankind can be a matter of indifference to me.

–Publius Terentius Afer, Heauton Timoroumenos (The Self-Tormentor) act i, sc i, l. 77 (165 BCE)(S.H. transl.)
