Plato supports the immortality of the soul in the Phaedo. He gives 3 arguments for his theory, the opposites, memory, and affinity arguments. Each argument offers an intriguing account for its claim that the soul must exist after death. His evidence and propositions for each account leave no room for counterarguments. Other philosophers such as Simmias and Cebes provide two different countermeasures to Plato's statement, however he carefully refutes them using his 3 arguments as a refutation. Plato's three arguments for proving the immortality and longevity of a soul provide clear and concise reasons to agree with his approach. Phaedo was put in prison. While in prison, Socrates pondered whether or not there is an afterlife and whether or not the soul can survive death. Explain that we discuss the soul because it applies to all humans; it is more personal, closer to us than the nature of being. Socrates adds that he does not fear death because it means fearing one's soul. You should not fear the unknown, but embrace it. Furthermore, he comes to the conclusion that the soul is immortal based on the following 3 arguments. Socrates' first argument is the argument from opposites. He says the soul is eternal. It never ceases to be nor does it ever become being. It is completely eternal. Everything arises from its opposite, so that for example a tall man becomes tall only because he was short before. Likewise, death is the opposite of life, and therefore living things arise from dead things and vice versa. This implies that there is a continuous cycle of life and death, so when we die we do not remain dead, but come back to life after a certain period of time. Our soul, however, never dies. It's the only thing that continues... middle of the paper... believes that the soul is long-lived and can outlive many bodies, but argues that this does not prove that the soul is immortal. How do we know that the soul suffers nothing when the body deteriorates and dies over the centuries? Socrates states that it is inconceivable to think that the soul is anything but alive. Affinity's argument states that anything invisible and immaterial will become immortal. Although there are good souls and bad souls, the soul itself is a thing that remains imperishable. All three arguments propose an intriguing account for Socrates' claim that the soul exists after death. Plato's three arguments for proving the immortality and longevity of a soul provide clear and concise reasons to agree with his approach. It seems that any counterargument can be argued using at least one of the three arguments, simply by asking the question.
