Just between us, slavery, preferably with a smile, is inevitable then. But we must not admit it. Isn’t it better that whoever cannot do without having slaves should call them free men? For the principle to begin with, and, secondly, not to drive them to despair. We owe them that compensation, don’t we? In that way, they will continue to smile and we shall maintain our good conscience. Otherwise, we’d be obliged to reconsider our opinion of ourselves; we’d go mad with suffering, or even become modest—for everything would be possible.
I guess what he is saying is that especially they who want servants, will not call them as such to maintain his and their dignity and his self-image, but their desire to be served still exists unspoken to others and themselves
