The history of free will has yet to be written. With few exceptions, the literature on the subject is dominated by legal and philosophical works, most of which recount the ideas of prominent thinkers or discuss hypothetical questions far removed from specific historical contexts. The following article seeks to redress the balance by tracing the debate on hypnosis in Germany from 1894 to 1936. Examining responses to hypnosis is tantamount to recording common understandings of autonomy and heteronomy, self-control and mind control, free will and automaticity. More specifically, it is possible to identify distinct philosophical positions related to the question as to whether hypnosis could surmount free will or not. The article demonstrates that the discourse often centred on the perceived struggle, located within a particular ‘personality’, between an individual's ‘character’ or ‘soul’ and the infiltration by a foreign or hostile force. While one group (compatibilists) emphasized the resilience of the ‘moral inhibitions’, another group (determinists) doubted that these were sufficient to withstand hypnosis.

Hypnosis was not the only subject that raised questions about the nature of free will. It would require a separate article, however, to address the way in which experts discussed the relationship between, say, alcohol abuse and free will. As will become clearer in the following pages, the connection between middle-class values and the exercise of free will might be assumed to have influenced discourse on this matter as well.

14 German thinking on free will was heavily indebted to Immanuel Kant's libertarian concepts of autonomy and Gesinnung (good will). According to the philosopher, laws of nature were imposed upon us from outside, whereas obeying the moral law was to be self-legislating and therefore not subject to the constraints of space and time. Good will, Kant had affirmed, was responsible for moral action and impervious to external influence. This concept of Gesinnung had had a huge impact on the country's legal system, permitting the state to combine Kant with the Christian concept of the fall of man (Sündenfall) to classify felons as moral sinners. Even the worst of circumstances, including abject poverty, could not detract from the will to do good or evil. See Becker, Peter, Verderbnis und Entartung: Eine Geschichte der Kriminologie des 19. Jahrhunderts als Diskurs und Praxis (Göttingen, 2000), pp. 44–9, 366–7Google Scholar.
