History of Western Philosophy - Bertrand Russell [85]
The soul, being eternal, is at home in the contemplation of eternal things, that is, essences, but is lost and confused when, as in sense-perception, it contemplates the world of changing things.
The soul, when using the body as an instrument of perception, that is to say, when using the sense of sight or hearing or some other sense (for the meaning of perceiving through the body is perceiving through the senses) … is then dragged by the body into the region of the changeable, and wanders and is confused; the world spins round her, and she is like a drunkard, when she touches change…. But when returning into herself she reflects, then she passes into the other world, the region of purity, and eternity, and immortality, and unchangeableness, which are her kindred, and with them she ever lives, when she is by herself, and is not let or hindered; then she ceases from her erring ways, and being in communion with the unchanging is unchanging. And this state of the soul is called wisdom.
The soul of the true philosopher, which has, in life, been liberated from thraldom to the flesh, will, after death, depart to the invisible world, to live in bliss in the company of the gods. But the impure soul, which has loved the body, will become a ghost haunting the sepulchre, or will enter into the body of an animal, such as an ass or wolf or hawk, according to its character. A man who has been virtuous without being a philosopher will become a bee or wasp or ant, or some other animal of a gregarious and social sort.
Only the true philosopher goes to heaven when he dies. 'No one who has not studied philosophy and who is not entirely pure at the time of his departure is allowed to enter the company of the Gods, but the lover of knowledge only.' That is why the true votaries of philosophy abstain from fleshly lusts: not that they fear poverty or disgrace, but because they 'are conscious that the soul was simply fastened or glued to the body—until philosophy received her, she could only view real existence through the bars of a prison, not in and through herself, … and by reason of lust had become the principal accomplice in her own captivity'. The philosopher will be temperate because 'each pleasure and pain is a sort of nail which nails and rivets the soul to the body, until she becomes like the body, and believes that to be true which the body affirms to be true'.
At this point, Simmias brings up the Pythagorean opinion that the soul is a harmony, and urges: if the lyre is broken, can the harmony survive? Socrates replies that the soul is not a harmony, for a harmony is complex, but the soul is simple. Moreover, he says, the view that the soul is a harmony is incompatible with its pre-existence, which was proved by the doctrine of reminiscence; for the harmony does not exist before the lyre.
Socrates proceeds to give an account of his own philosophical development, which is very interesting, but not germane to the main argument. He goes on to expound the doctrine of ideas, leading to the conclusion 'that ideas exist, and that other things participate in them and derive their names from them'. At last he describes the fate of souls after death: the good go to heaven, the bad
