Suppose the only way to induce the terrorist suspect to talk is to torture his young daughter (who has no knowledge of her father’s nefarious activities). Would it be morally permissible to do so? I suspect that even a hardened utilitarian would flinch at the notion. But this version of the torture scenario offers a truer test of the utilitarian principle. It sets aside the intuition that the terrorist deserves to be punished anyhow (regardless of the valuable information we hope to extract), and forces us to assess the utilitarian calculus on its own.
