Huzarek, T. (Tomasz). "Knowledge Argument versus Bundle Theory according to Derek Parfit". Scientia et Fides. 5 (2), 2017, 237 - 250
According to constitutive reductionism of Derek Parfit, a subject/person is not a separate existing being but his existence consists in the existence of a brain and body, performance of actions, thinking and occurrence of other physical and mental events. The identity of the subject in time comes down only to “Relation R” - mental consistency and/or connectedness – elicited by appropriate reasons. In the following article, I will try, relying on Frank Johnson's Knowledge Argument, to argue in favour of the following conclusions: (1) a person/subject is a “fact”irreducible to body and physical relations with the environment and (2) a subject is something/”fact” non-reducible to mental occurrences.
