In this paper it is argued that Habermas' critique of German Idealism is misguided and that his rejection of the philosophy of the subject is unjustified. Critical Theory needs to recognise the importance of subjectivity for all social philosophy if its theoretical aims are to be achieved. In order to demonstrate the relevance of subjectivity to Critical Theory the essay draws on analytic philosophy of mind and on the work of Manfred Frank and Dieter Henrich.
