This paper engages Rainer Forst's doctrine of noumenal power. At the centre of this doctrine is its signature claim that power is noumenal in nature. I reconstruct Forst's definition of power and distinguish three conceptions of noumenal power in his writings. I argue that, on each conception, we should reject that claim. It emerges that the professed noumenality of power is either a trivial feature of power, or else a feature only of some forms of power. Consequently, Forst's definition of power cannot be adequate and the claim that power is noumenal in nature is either trivial or false.

This article argues that alienation (as Entfremdung) should be understood as a particular form of individual and social heteronomy that can only be overcome by a dialectical combination of individual and collective autonomy, recovering a deontological sense of normative authority. If we think about alienation in Kantian terms, the main source of alienation is a denial of standing or, in the extreme, losing a sense of oneself as a rational normative authority equal to all others. I call the former kind of alienation, where persons deny others equal standing as a normative authority in moral or political terms, first order noumenal alienation, as there is no proper mutual cognition and recognition of each other in such a social context. I call the latter kind of alienation, where a subject does not consider themselves an equal normative authority – or an ‘end in oneself’ – second order noumenal alienation (again, in a moral and a political form). In this sense, alienation violates the dignity of humans as moral and political lawgivers – a dignity seen by Rousseau, Kant and Marx as inalienable: It can be denied or violated, but it cannot be lost.
