Compatibilism and the Law of Surprise: Myth, Free Will, Destiny, and Hedgehogs

One of the most bewildering concepts in the Witcher television series is the so-called “Law of Surprise”—a concept with philosophical implications as massive as Geralt’s biceps! For new fans of the Witcher TV show, episode flashbacks and flash forwards combine with the Law to make for a steep learning curve. The Law of Surprise befuddles viewers at several points in the series, especially during the betrothal banquet scene. It begs for a helpful explanation . This chapter offers that, plus a novel account of the Law tied to the stance in the debate about free will and determinism known as “compatibilism.” Determinism is the position that anything that occurs at any given moment in time necessarily occurs the way it does because of what occurred the moment before. If determinism is true, then given the laws of physics and causation we should, in principle, be able to predict all future occurrences. Libertarianism is the exact opposite position: humans possess free will and so can choose to do otherwise, so not all occurrences are determined in advance. Compatibilism is the position that libertarianism and determinism are compatible, so that despite most occurrences being determined in advance, humans can nevertheless choose to act out of a capacity to realize their own intentions, to freely will outcomes or to behave unpredictably.
