A quote
The result of it all is that these slaves, who may not talk in their master’s presence, talk about their master. But the slaves of former days, who were permitted to converse not only in their master’s presence, but actually with him, whose mouths were not stitched up tight, were ready to bare their necks for their master, to bring upon their own heads any danger that threatened him; they spoke at the feast, but kept silence during torture.
