“Kindly remember that he whom you call your slave sprang from the same stock, is smiled upon by the same skies, and on equal terms with yourself breathes, lives and dies.”
Letter XLVII: On master and slave, line 10.
Epistulae Morales ad Lucilium (Moral Letters to Lucilius)
Context: Kindly remember that he whom you call your slave sprang from the same stock, is smiled upon by the same skies, and on equal terms with yourself breathes, lives and dies. It is just as possible for you to see in him a free-born man as for him to see in you a slave.

Vis tu cogitare istum quem servum tuum vocas ex isdem seminibus ortum eodem frui caelo, aeque spirare, aeque vivere, aeque mori! tam tu illum videre ingenuum potes quam ille te servum.
