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.
Daniel Kolak
Kolak is the originator of the philosophy known as Open Individualism, which he developed along with his view of metaphysical subjectivism and the nonlocality of consciousness, according to which there exists but one numerically identical individual subject who is everyone. In his groundbreaking "I Am You: the Metaphysical Foundations for Global Ethics", he writes: "The central thesis of "I Am You" - that we are all the same person - is apt to strike many readers as obviously false or even absurd. How could you be me and Hitler and Gandhi and Jesus and Buddha and Greta Garbo and everybody else in the past, present and future? In this book I explain how this is possible. Moreover, I show that this is the best explanation of who we are for a variety of reasons, not the least of which is that it provides the metaphysical foundations for global ethics." Variations on Kolak's theme have been voiced periodically throughout the ages (the Upanishads, Averroes, Giordano Bruno, Schopenhauer, Josiah Royce); more recently, physicists such as Erwin Schrödinger, Fred Hoyle, and Freeman Dyson have espoused it.
