The existence of evil is compatible with the existence of God, most theists would claim, because evil either results from the activities of free agents, or it contributes in some way toward their moral development. According to the ‘free-will defence’, evil and suffering are necessary consequences of free-will. Proponents of the ‘soul-making argument’—a theodicy with a different emphasis—argue that a universe which is imperfect will nurture a whole range of virtues in a way impossible either in a perfect world, or (...) in a totally evil one. The pain of animals is widely thought to constitute a major difficulty for both of these accounts, for if we ask whether the only evils present in the world result directly from the free actions of created agents, or contribute in some way to ‘soul-making’ of such agents, we are bound to admit that, on the face of it, much animal pain does not.

Do animals other than humans feel pain? How do we know? Well, how do we know if anyone, human or nonhuman, feels pain? We know that we ourselves can feel pain. We know this from the direct experience of pain that we have when, for instance, somebody presses a lighted cigarette against the back of our hand. But how do we know that anyone else feels pain? We cannot directly experience anyone else's pain, whether that "anyone" is our best friend (...) or a stray dog. Pain is a state of consciousness, a "mental event", and as such it can never be observed. Behavior like writhing, screaming, or drawing one's hand away from the lighted cigarette is not pain itself; nor are the recordings a neurologist might make of activity within the brain observations of pain itself. Pain is something that we feel, and we can only infer that others are feeling it from various external indications. (shrink)
