Socrates, Celebs and Simmas agree that the opposite of life is death and vice versa. With this notion of the opposite they agree that when man is born, he comes from death. And when man dies he passes from life to death. With this conclusion it is the soul that comes to life from death. And if the soul comes to life from death, it must go to death from life. And if he goes to death from life and to life from death, he must exist after death to be reborn. Therefore, the philosopher should not fear death, with the idea that he will be reborn because the soul is immortal, it only changes between life and life.
