I think I got it!! It's ironically saying that the slave has just as much rights as a useful horse/mule/cow/goat/dog: none.

That's what I'll assume, and sorry for always asking for help, then getting it before anyone says anything! I don't know why, but it's (almost) been always like this! X(

Anyway, I'll log off! Hopefully, I'll finish my assignments in time and score well on my tests!
