Colin Klein, “What the Body Commands: The Imperative Theory of Pain” (MIT Press, 2015)

Nothing seems so obviously true as the claim that pains feel bad, that pain and suffering go together. Almost as obviously, it seems that the function of pain is to inform us of tissue damage. In What the Body Commands: The Imperative Theory of Pain (The MIT Press, 2015), Colin Klein denies both apparently obvious claims. On his view, pain is a “protective imperative” whose content is to protect the body or body part: for example, “Don’t put weight on that left ankle!” Klein, Lecturer in the Department of Philosophy at Macquarie University, discusses the problem of pain asymbolia, in which people report feeling pain but are not the least bit motivated to do anything about it; considers how to explain masochistic pleasure, where we deliberately act in ways that do not protect the body; and addresses the question: why do pains (typically, but contingently) hurt?
