 The development of hermeneutics since Gadamer forwarded his ‘philosophical hermeneutics’ in Truth and Method has been fostered by philosophical controversies about the consequences of his project. The most significant of these controversies are about the consequences of philosophical hermeneutics in relation to critical theory and to  deconstruction.[9]  Although philosophical interest in these controversies is extensive, in each case, discussion arises in close connection with Gadamer himself. In the case of the controversy in relation to critical theory, discussion originates between Jürgen Habermas and Gadamer over the problem of critique, or, more specifically, the critique of ideology. In the case of the controversy in relation to deconstruction, discussion originates between Jacques Derrida and Gadamer. While this discussion is itself layered and gives rise to new questions over time, it concerns, in part, the question of whether the success of understanding genuinely achieves a determination of meaning.
