Dialogical self
Inspired by the original ideas of William James and Mikhail Bakhtin, Hubert Hermans, Harry Kempen and Rens van Loon wrote the first psychological publication on the "dialogical self" in which they conceptualized the self in terms of a dynamic multiplicity of relatively autonomous "I"-positions in the (extended) landscape of the mind. In this conception, the "I" has the possibility to move from one spatial position to another in accordance with changes in situation and time. The "I" fluctuates among different and even opposed positions, and has the capacity to imaginatively endow each position with a voice so that dialogical relations between positions can be established. The voices function like interacting characters in a story, involved in processes of question and answer, agreement and disagreement. Each of them have a story to tell about their own experiences from their own stance. As different voices, these characters exchange information about their respective Me's and mines, resulting in a complex, narratively structured self.
Discourse ethics
German philosophers Jürgen Habermas and Karl-Otto Apel are considered the originators of modern discourse ethics. Habermas's discourse ethics is his attempt to explain the implications of communicative rationality in the sphere of moral insight and normative validity. It is a complex theoretical effort to reformulate the fundamental insights of Kantian deontological ethics in terms of the analysis of communicative structures. This means that it is an attempt to explain the universal and obligatory nature of morality by evoking the universal obligations of communicative rationality. It is also a cognitivist moral theory, which means it holds that justifying the validity of moral norms can be done in a manner analogous to the justification of facts. However, the entire project is undertaken as a rational reconstruction of moral insight. It claims only to reconstruct the implicit normative orientations that guide individuals and it claims to access these through an analysis of communication.
