You’ve come into possession of one vial of truth serum. Who would you give it to (with the person’s consent, of course) — and what questions would you ask?
Two things came to mind when reading this. First, don’t do something to others that you wouldn’t want done to you, and second, what you don’t know won’t hurt you.
Words can hurt, and even if we think we want to know the truth, I’m not so sure we always want to know. For me, I wouldn’t give that serum to anyone, I would never consent to it, and there are probably things I just don’t want to know. Silence isn’t always that bad.
