The Preservationist holds that, to save others from suffering truly serious losses, like the loss of life or limb, often it's wrong to lie, and to cheat, and to steal, even though nobody will ever suffer much from your doing any of that. By contrast, the Liberationist holds that, when necessary to lessen serious suffering, then, provided nobody suffers seriously in consequence of your so doing, it's always morally good to do all those unruly things and more.
