At various times in history, philosophers have struggled with the issue of personal identity trying to uncover the essential property that preserves a person’s identity through time.

Moreover, human bodies change over time: we lose and gain atoms, but we remain the same organisms with the same personal identity because there is still physical continuity. A person will persist over time because he or she will own the same body from birth to death. All things considered, many objections were raised against the body theory including the body transplant and memory theory; both oppositions asserted that physiological continuity is inessential for personal identity. The body transplant is a far-future possibility so far immeasurable and inconclusive, and the memory theory has its unexplained enigmas.

The body is defined as a sophisticated biological entity, and bodily continuity is personal identity; for instance, Eve on earth requires the same physical and chemical components to survive as an …show more content…
