The Unity of the Self

Before asking whether a Self is a unity or a multiplicity, one must answer a more fundamental question, the one concerning the very existence of Self. However, in this case, the positive or negative judgment of existence are intimately linked, that is to say, whenever a philosopher asserts or denies the existence of the Self, he does so because of his more or less tacit assumptions on the self's essence. That is why much Philosophy of the Mind and much (theoretical as well as experimental) Cognitive Psychology remain entangled with misunderstanding and unthought metaphysical beliefs.
The philosophical methodology followed in our research originates in Kantian transcendental arguments. Thus, only should one conclude that the Self exists if it is a condition of possibility of some well-established psychological phenomena. By the same token, skepticism and dogmaticism over its unity or multiplicity (and other possible features, such as identity over time, agency, self-awareness, etc.) can only be surpassed by evidence of their presence
