Final answer:
It is reasonable to believe the world will continue to exist after one's death due to the stability of natural processes that operate independently of individual human experience, supported by long-standing observations and scientific understanding.
Step-by-step explanation:
It is reasonable to believe that the world will continue to exist after one's death because our understanding of reality is not exclusively tied to our personal perspective. Just as we accept the continuation of natural phenomena, like the sun rising each day, beyond our immediate observation, we can also infer that the world will persist when we are no longer here to perceive it. This reasoning is similar to that employed in scientific predictions, which are based on long-standing observations and theories, suggesting a stability in natural processes that is independent of individual human existence. Moreover, psychic phenomena and cultural beliefs about life after death, although influential for personal belief systems, do not rationally compel the universal conclusion that the world ceases to exist upon our death.
Furthermore, these mental habits and belief systems often serve a functional purpose for individuals, providing a sense of comfort or continuity that is emotionally, rather than rationally, grounded. While it is understandable to seek solace in beliefs of an afterlife or spiritual continuity, the objective continuation of the world suggests that it is part of a broader reality that extends beyond our individual lifespans. The persistence of the universe, as commonly understood by human belief and scientific understanding, supports the view that it will remain after any single person's death.
