An Immortal Soul
As I explained, Plato believed that reality is divided into two regions.
One region is the world of the senses, about which we can only have approximate or incomplete knowledge by using our five (approximate or incomplete) senses. In this sensory world, “everything flows” and nothing is permanent. Nothing in the sensory world is, there are only things that come to be and pass away.
The other region is the world of ideas, about which we can have true knowledge by using our reason. This world of ideas cannot be perceived by the senses, but the ideas (or forms) are eternal and immutable.
According to Plato, man is a dual creature. We have a body that “flows,” is inseparably bound to the world of the senses, and is subject to the same fate as everything else in this world—a soap bubble, for example. All our senses are based in the body and are consequently unreliable. But we also have an immortal soul—and this soul is the realm of reason. And not being physical, the soul can survey the world of ideas.
But that’s not all, Sophie. IT’S NOT ALL!
Plato also believed that the soul existed before it inhabited the body, (it was lying on a shelf in the closet with all the cookie molds.) But as soon as the soul wakes up in a human body, it has forgotten all the perfect ideas. Then something starts to happen. In fact, a wondrous process begins. As the human being discovers the various forms in the natural world, a vague recollection stirs his soul. He sees a horse—but an imperfect horse. (A gingerbread horse!) The sight of it is sufficient to awaken in the soul a faint recollection of the perfect “horse,” which the soul once saw in the world of ideas, and this stirs the soul with a yearning to return to its true realm. Plato calls this yearning eras—which means love. The soul, then, experiences a “longing to return to its true origin.” From now on, the body and the whole sensory world is experienced as imperfect and insignificant. The soul yearns to fly home on the wings of love to the world of ideas. It longs to be freed from the chains of the body.
Let me quickly emphasize that Plato is describing an ideal course of life, since by no means all humans set the soul free to begin its journey back to the world of ideas. Most people cling to the sensory world’s “reflections” of ideas. They see a horse—and another horse. But they never see that of which every horse is only a feeble imitation. (They rush into the kitchen and stuff themselves with gingerbread cookies without so much as a thought as to where they came from.) What Plato describes is the philosophers’way. His philosophy can be read as a description of philosophic practice.
When you see a shadow, Sophie, you will assume that there must be something casting the shadow. You see the shadow of an animal. You think it may be a horse, but you are not quite sure. So you turn around and see the horse itself—which of course is infinitely more beautiful and sharper in outline than the blurred “horse-shadow.” Plato believed similarly that all natural phenomena are merely shadows of the eternal forms or ideas. But most people are content with a life among shadows. They give no thought to what is casting the shadows. They think shadows are all there are, never realizing even that they are, in fact, shadows. And thus they pay no heed to the immortality of their own soul.
Out of the Darkness of the Cave
Plato relates a myth which illustrates this. We call it the Myth of the Cave. I’ll retell it in my own words.
Imagine some people living in an underground cave. They sit with their backs to the mouth of the cave with their hands and feet bound in such a way that they can only look at the back wall of the cave. Behind them is a high wall, and behind that wall pass human-like creatures, holding up various figures above the top of the wall. Because there is a fire behind these figures, they cast flickering shadows on the back wall of the cave. So the only thing the cave dwellers can see is this shadow play. They have been sitting in this position since they were born, so they think these shadows are all there are.
Imagine now that one of the cave dwellers manages to free himself from his bonds. The first thing he asks himself is where all these shadows on the cave wall come from. What do you think happens when he turns around and sees the figures being held up above the wall? To begin with he is dazzled by the sharp sunlight. He is also dazzled by the clarity of the figures because until now he has only seen their shadow. If he manages to climb over the wall and get past the fire into the world outside, he will be even more dazzled. But after rubbing his eyes he will be struck by the beauty of everything. For the first time he will see colors and clear shapes. He will see the real animals and flowers that the cave shadows were only poor reflections of. But even now he will ask himself where all the animals and flowers come from. Then he will see the sun in the sky, and realize that this is what gives life to these flowers and animals, just as the fire made the shadows visible.
The joyful cave dweller could now have gone skipping away into the countryside, delighting in his new-found freedom. But instead he thinks of all the others who are still down in the cave. He goes back. Once there, he tries to convince the cave dwellers that the shadows on the cave wall are but flickering reflections of “real” things. But they don’t believe him. They point to the cave wall and say that what they see is all there is. Finally they kill him.
What Plato was illustrating in the Myth of the Cave is the philosopher’s road from shadowy images to the true ideas behind all natural phenomena. He was probably also thinking of Socrates, whom the “cave dwellers” killed because he disturbed their conventional ideas and tried to light the way to true insight. The Myth of the Cave illustrates Socrates’ courage and his sense of pedagogic responsibility.
Plato’s point was that the relationship between the darkness of the cave and the world beyond corresponds to the relationship between the forms of the natural world and the world of ideas. Not that he meant that the natural world is dark and dreary, but that it is dark and dreary in comparison with the clarity of ideas. A picture of a beautiful landscape is not dark and dreary either. But it is only a picture.
The Philosophic State
The Myth of the Cave is found in Plato’s dialogue the Republic. In this dialogue Plato also presents a picture of the “ideal state,” that is to say an imaginary, ideal, or what we would call a Utopian, state. Briefly, we could say that Plato believed the state should be governed by philosophers. He bases his explanation of this on the construction of the human body.
According to Plato, the human body is composed of three parts: the head, the chest, and the abdomen. For each of these three parts there is a corresponding faculty of the soul. Reason belongs to the head, will belongs to the chest, and appetite belongs to the abdomen. Each of these soul faculties also has an ideal, or “virtue.” Reason aspires to wisdom, Will aspires to courage, and Appetite must be curbed so that temperance can be exercised. Only when the three parts of the body function together as a unity do we get a harmonious or “virtuous” individual. At school, a child must first learn to curb its appetites, then it must develop courage, and finally reason leads to wisdom.
Plato now imagines a state built up exactly like the tripartite human body. Where the body has head, chest, and abdomen, the State has rulers, auxiliaries, and fa-borers (farmers, for example). Here Plato clearly uses Greek medical science as his model. Just as a healthy and harmonious man exercises balance and temperance, so a “virtuous” state is characterized by everyone knowing their place in the overall picture.
Like every aspect of Plato’s philosophy, his political philosophy is characterized by rationalism. The creation of a good state depends on its being governed with reason. Just as the head governs the body, so philosophers must rule society.
Let us attempt a simple illustration of the relationship between the three parts of man and the state:
BODY SOUL VIRTUE STATE
head reason wisdom rulers
chest will courage auxiliaries
abdomen appetite temperance laborers
Plato’s ideal state is not unlike the old Hindu caste system, in .which each and every person has his or her particular function for the good of the whole. Even before Plato’s time the Hindu caste system had the same tripartite division between the auxiliary caste (or priest caste), the warrior caste, and the laborer caste. Nowadays we would perhaps call Plato’s state totalitarian. But it is worth noting that he believed women could govern just as effectively as men for the simple reason that the rulers govern by virtue of their reason. Women, he asserted, have exactly the same powers of reasoning as men, provided they get the same training and are exempt from child rearing and housekeeping. In Plato’s ideal state, rulers and warriors are not allowed family life or private property. The rearing of children is considered too important to be left to the individual and should be the responsibility of the state. (Plato was the first philosopher to advocate state-organized nursery schools and full-time education.)
After a number of significant political setbacks, Plato wrote the tows, in which he described the
