A few days ago I remembered a short story that I was taught in high-school, and I'm trying to find from what book it comes from.
The story goes something like this:
A Roman senator was at a dinner party, he was bored of the people there because he thought that no one matched his intellectual standards. Until a few hours later when he met another man, they start talking and the senator was pleased to see a kindred spirit in that party, a man of rich culture, and a broad mind. He was so pleased and he enjoyed so much the time spent with this person that he asked him to meet again, but the man replied:-"I can't I don't think my master would allow it". The senator left immediately in an outrage, and then he told another senator:-"This is unbelievable, we should pass a law forcing slaves to wear something to identify themselves, so this doesn't happen again" and the other senator replied:-"I don't think that would be possible, if we do it they will figure out that there are more of them than us."
This is a short story from that book, and well, I've been searching for that book, but I haven't found it so far.
Any clue would help. Thanks!
