A new political ethics that confronts the injustices of liberal democracy. Infinitely Demanding is the clearest, boldest and most systematic statement of Simon Critchley's influential views on philosophy, ethics, and politics. Part diagnosis of the times, part theoretical analysis of the impasses and possibilities of ethics and politics, part manifesto, Infinitely Demanding identifies a massive political disappointment at the heart of liberal democracy and argues that what is called for is an ethics of commitment that can inform a radical politics. Exploring the problem of ethics in Kant, Levinas, Badiou, and Lacan that leads to a conception of subjectivity based on the infinite responsibility of an ethical demand, Critchley considers the possibility of political subjectivity and action after Marx and Marxism. Infinitely Demanding culminates in an argument for anarchism as an ethical practice and a remotivating means of political organization.
