Both positions of personal identity over time ask whether we "follow people" or "human beings." By analyzing Locke's account of personal identity and his definition of a "person", the first aspect of this argument will be explained. However, unlike Locke's theory, the second position which considers us "human beings" will also be evaluated, as advocated by animalists like Olson. In response to this, examples of cases such as amnesia will also be considered and how Perfect's theory of psychological continuity resolves earlier objections to Locke's argument made by Butler and Reid. The conclusion obtained will show support for this new Lockean theory of personal identity due to the theory of psychological continuity and the inability of animalism to fully justify its claims from the point of view of personal identity and not only from an identity perspective. The question of personal identity over time arises: "What does one and the same person do to a person over time? This can also be written as what makes same person at T1 (at one time) and Y at T2 (at a later time) John Locke attempted to answer this question, by first defining what he meant by a “person”; “[A] person is a self-aware rational being (i.e., a being with a mind and the capacity to reason, deliberate, and choose) who can rightly be held responsible for one's choices. "This definition of a person is essential in determining personal identity, in Locke's view, because being the same "man" means having the same body throughout time. is the consciousness which "alone makes the self". Psychological continuity is essential in creating a coherent theory of personal identity that does not view victims of amnesia as nonexistent. It is in this continuous chain of memory links that allows personal identity, as a meaningful concept in itself, to endure.
