8What is the difference between a wink and a blink? The answer is important not only to philosophers of mind, for significant moral and legal consequences rest on the distinction between voluntary and involuntary behavior. However, action theory--the branch of philosophy that has traditionally articulated the boundaries between action and non-action, and between voluntary and involuntary behavior--has been unable to account for the difference.

Alicia Juarrero argues that a mistaken, 350-year-old model of cause and explanation--one that takes all causes to be of the push-pull, efficient cause sort, and all explanation to be prooflike--underlies contemporary theories of action. Juarrero then proposes a new framework for conceptualizing causes based on complex adaptive systems. Thinking of causes as dynamical constraints makes bottom-up and top-down causal relations, including those involving intentional causes, suddenly tractable. A different logic for explaining actions--as historical narrative, not inference--follows if one adopts this novel approach to long-standing questions of action and responsibility.
