Transcendental Phenomenology of Dementia. A ‘Mutual Enlightenment’ Concrete Proposition

This contribution aims to be a concrete proof of how fertile, rich and innovative dialogue and confrontation between transcendental phenomenology and naturalising sciences can be. Through the phenomenological-transcendental analysis of the neurodegenerative pathology of dementia, an attempt will be made to propose, within the debate on the possible naturalisation of phenomenology, the perspective of an actual mutual enlightenment, as proposed by Gallagher. Not a naturalisation of consciousness in the sense of a reduction to neural process, but a pluralisation of the valid and rigorous perspectives through which it can be investigated. The phenomenological-transcendental eidetic study of dementia thus becomes complementary to the neurobiological one, revealing what the subject feels ‘from within’, his losses, but also what persists in the patient until the most advanced stages. Such a study, in synergy with the biological one, would greatly help in the holistic understanding of dementia in this particular case and, in general, of consciousness phenomena.
