Like Sophocles' Antigone, the work of Lars von Trier is often called upon to illustrate a point regarding ethics. Among those who so use these works are many Lacanians, such as Žižek, and, indeed, Lacan himself draws on Antigone in The Ethics of Psychoanalysis. What needs to be clarified, however, is that Lacan does not, in his discussion of ethics, point to Antigone as an example of the ethical. Rather, he utilizes Antigone to discuss how ethics functions always subjectively. That is to say, for Lacan, key to understanding ethics is an understanding of the act in relation to desire. In drawing this lesson out of Lacan's seminar, Lacan's notion of ethics, his treatment of Antigone, and also, by extension, what it is that makes von Trier's films so ethically significant and amongst the most important film works of our time, can be better understood.
