Parfit's reductionist account of personal identity entails that the agent who acted and the agent who might 'reverse' the act are not numerically identical, making artifact-repair and action-reversal symmetrically impossible for the same agent.

Action-reversal(as paired with artifact-repair to illustrate the philosophical problem): Undoing or completely canceling out the effects of something someone did, returning the situation to how it was before the action happened.
Artifact-repair(as an example of an action being discussed): The act of fixing a man-made object that has been broken or damaged, restoring it to a previous state.
Numerically identical(as used to describe whether two agents are the exact same person): Being literally the same thing, not just similar or alike—like how the person you are today is numerically identical to the person you were yesterday (one and the same individual).
Parfit: Derek Parfit was a highly influential British philosopher known for revolutionizing how we think about personal identity, morality, and what makes life worth living. He argued that our sense of being a continuous, unified "self" is partly an illusion, and that what really matters is the continuation of our thoughts and experiences, not some invisible thread connecting us through time. His ideas have shaped modern ethics and how philosophers approach questions about identity, responsibility, and how we should treat future generations.
