Aristotle Introduction Last week we talked about Socrates and Plato. I emphasized the importance of the world of questions in Socrates and Plato’s understanding of the soul as foundational to the understanding of these two philosophers. What they have in common is that both were seeking a way to find a truth that was not merely subjective opinion and relative. Through the Socratic method of questioning and the study of certain subjects, especially math and astronomy, Plato believed he had found a way to discovering absolute truth, a truth that could be depended on. And he found that the mind was a more certain ally then the senses, which could give false information. His ultimate conclusion seems to be that there is a more real world that surrounds and supports this physical world. This more real world is entirely spiritual and transcends this world. With Aristotle, however, we will come back to earth and our senses. It is as important to understand Aristotle, as it is to understand Socrates and Plato. He had a very important role to play in the history of Western culture and we are really the beneficiaries of two different streams of thought, both of which are still influencing us today and both still offer us much to ponder. If there is any “new truth” to emerge in modern philosophy one thing will be certain: It will need to embrace both these ways of approaching reality, the Platonic and the Aristotelian. Aristotle was born in 384 in Thrace. This is 15 years after the death of Socrates. Aristotle’s father was a physician. Perhaps this influenced his life long love of biology and science. Aristotle came to Athens to study at Plato’s academy when he was 17 years old. He studied with Plato for 20 years until Plato’s death in 348. After Plato’s passing Aristotle traveled, married, and did some teaching before he was invited to the Macedonian court to become the tutor of Alexander the Great who was then 13 years old. He continued in this position for 7 years until Alexander became king. Aristotle then returned to Athens to start his own school, the Lyceum. He spent most of the rest of his life there. He died when he was 62 after leaving under duress after Alexander died and he was criticized for his relationship with the king. He did not want to see Athens “sin against philosophy a second time.” There are probably few people as brilliant as Aristotle who had such widespread interests. “He investigated such diverse fields as biology (his minute observations include the life cycle of the gnat), mathematics, astronomy, physics, literary criticism (the concept of catharsis---art as release of emotion), rhetoric, logic (deductive and inductive), politics (he analyzed 158 Greek and foreign constitutions), ethics, and metaphysics. His knowledge was so encyclopedic that there is hardly a college course today that does not take note of what Aristotle had to say on the subject. Although his works on natural science are now little more than curiosities, they held a place of undisputed authority until the scientific revolution of the sixteenth and seventeenth centuries. But in no important sense are his humanistic studies, such as the Ethics and the Politics, out of date” (Civilization, pp. 109-110). We encounter an interesting problem when trying to understand Aristotle. Unlike Plato, we have none of Aristotle’s published writings. All we really have is his unpublished lecture notes and texts for his students that were brought together and organized centuries later. Scholars would have loved to have had a look at Plato’s lectures. Part of the reason for this is that it is believed that both of their lectures were more private and specialized, while their published writings were for the more general public. So with Plato we would love to know what he had to say to his students in the privacy of the Academy and with Aristotle we would love to know what he wanted the general population to understand about his philosophy. But we do have what we have and that is enough to come to a general understanding of Aristotle’s philosophy. What Is Real? Aristotle studied for twenty years at Plato’s academy. From at first fully embracing Plato’s ideas Aristotle would eventually break away with a quite distinct philosophy of his own. But we must not make too much of this in terms of a break. While there was a difference and a development of thought, Aristotle never lost respect and admiration for his teacher. As Plato would forever be grateful to Socrates, so Aristotle would forever be grateful to Plato. Aristotle wrote about Plato: Of that unique man Whose name is not to come from the lips of the wicked. Theirs is not the right to praise him--Him who first revealed clearly By word and deed That he who is virtuous is happy. Alas, not one of us can equal him” (Copleston, p. 287) But differences there were. Plato is the great speculative philosopher. He takes us to the heights of mystical intuition about the true nature of reality. But how do we ground what he is saying in the real world of our everyday life? How do we live with these ideas? Now there is the rub! Is Plato’s description of the soul accurate? How do we know? How do we verify and experience this? If these are some of your questions then Aristotle may be your philosopher for he shared these same questions. Plato found truth in the mind. Remember? The nous is related to the logos. That is our source of truth. The senses can deceive us. Just think of optical illusions. How can we trust what we see? In spite of this, Aristotle did not share Plato’s distrust of the world of the senses. For Aristotle this world of daily experience and empirical evidence was the real world. How could there be a more real world than this one, a world that we could not see or touch? Aristotle recognized that we experience Plato’s abstract world of the mind; we can sense the true, the good, and the beautiful, but we did so only in concrete form. That is we see beautiful things and beautiful people, we don’t see “beauty” itself separate from anything. To talk about this Aristotle came up with his teaching about “substances.” Aristotle’s category of substances tries to explain the same experiential phenomena as Plato, but in a more empirical and understandable way. And substance is primary. For example, Socrates is a person. He is real. He was alive physically and present. That historical Socrates was the primary substance. Anything you want to say about him, his courage or wisdom is not a thing in itself such as with the Ideas. They are derivative of his basic being, his substance. Plato’s mistake, according to Aristotle, was to make the qualities that are derivative (such as courage and wisdom) real in themselves. This was confusing because there is no evidence (a key word) that they have independent existence in themselves. Aristotle makes an important distinction between substances and qualities. A substance is a chair. The chair’s size and color are qualities. This was reversal of what Plato had thought. What were most real for Plato were the Ideas and specific things were derivative from the Ideas. A specific horse is derivative of “horseness.” Things received their meaning from the Ideas. For Aristotle what was most real were things and what seemed like universals were only a way of speaking, for they gained their reality from things; they did not give reality to things. And yet Aristotle moved back toward Plato with his teaching about “forms.” A substance is not simply a thing that exists but it is matter (material stuff) combined with “form” which he describes as “an intelligible structure” (Tarnas, p 57). A person then was a combination of matter and form. This is what allows matter to come together as a person in one place and a horse in another. In many ways this seems just like Plato’s Ideas. Is there a difference? Yes. The forms were not self-existent in a transcendent world. They were not separate from matter. It is like the design for an engine does not exist in some other world. The design is in fact a part of the engine. All the parts that go into an engine could, in fact, make something else with a different design. So matter is matter, design gives it a form, and the way you would describe that engine, for example, big, powerful, etc. are qualities of the substance, the engine. But neither the qualities nor the design are real in themselves. That is the main point. But the form is more than a static design. It is a potential, a force moving something from one state into another. This is how Aristotle explained change and growth. And in this sense it is interesting to note that where Plato was inspired by abstract mathematics, Aristotle was inspired by biology. For example, the form of a tree is in the seed. The form actualizes itself over time. It is not static but moves in a forward direction. Matter can take the form of one seed or another but part of that form needs to come into being over time. It is almost as if matter itself is inert, but when matter combines with form, then movement and growth are possible, at it becomes a substance, something that can have qualities. The Structure of Thought If all of this sounds very structured that is because it is! Aristotle was a great organizer and categorizer. He did this with plants and he did it with language. It is a key to understanding both him and his philosophy. One of the ideas of logic is to be clear and precise and Aristotle tried to make each intellectual task he undertook as clear and precise as possible. An interesting aspect of Aristotle’s ideas about substance and form is that it made the process of becoming, of growth a real and good thing of itself. With Plato, the world of becoming is the world of imitation. The world of the Ideas is the world of Being. Being is the goal and becoming is a process. But with Aristotle, being and becoming are both an inherent part of form and matter. They both have equal status. For example, you can think about this in terms of child development. For Plato, a child would be the shadow of the adult. But for Aristotle, the child is just as important as the adult. The different philosophies end up giving a different value system for things of this world. This understanding had a direct effect on how Aristotle saw empirical studies, especially regarding sensory experience. While it is true that our senses can deceive us, (remember the railroad tracks converging in the distance), it is also true that our senses are what gives us our first and most basic knowledge of the world. While it is true we have to apply our ability to reason to what information our senses bring us, we still need and can use that information. And while our senses are more doubtful than Plato’s direct apprehension of the Ideas, they are also much more accessible for the average person! But Aristotle recognized that the mind had to work on the sense perceptions to arrive at truth and understanding and so he turned his fine mind toward defining how it is we think and how we can learn to think more clearly and precisely. We have already seen examples of this in how he showed that substance should not be confused with the qualities of substance and how substance itself could be understood as a combination of matter and form. On the Soul and the Divine We don’t know if Aristotle believed the soul was immortal, as did Plato and Socrates. For Aristotle, the soul was the form of the body and the body was the matter of soul. Remember that when matter and form come together, you have a substance, in this case a specific human being. But we do know that Aristotle placed a great deal of emphasis on Nous, that is, the mind, the active intellect that separated people from other living beings. The active intellect in a human being was the “only thing that came in from the outside.” It seems to be not only the part of us that can recognize truth but that it can somehow participate in the Divine intellect that seems to give order to the universe. And, in fact, the development and use of our active intellect in pursuing philosophical truth is our greatest happiness for it is reaching our highest potential. You can still feel Plato’s influence here. For this reason, Aristotle felt that the mind could be used to understand the natural world. He was aware that the senses could be tricked, but he also realized that there seemed to be an underlying order to the universe that was knowable if studied carefully. Nature would reveal her secrets to the persistent seeker. Because the world was intelligent, it could be understood by the intelligence of the active intellect. He shared this with Plato while insisting that the forms we could know and learn about did not have an independent, more real existence than the substances in which they showed up. What had been transcendent in Plato was now immanent in Aristotle. The birth of modern science can probably be found in the pre-Socratic philosophers who started to ask the right questions. But it is really with Aristotle that the scientific quest gains real momentum as it becomes systematic and more precise and gains in stature as a way to seek truth and to try to understand what is really real. If the pre-Socratic followers tried to find the source of life in the objective world while Socrates and Plato turned to the inner world, Aristotle was the one who tried to bridge those two ways together. The universe had intelligence, intention, and form, but these were to be studied in nature rather than outside of it. One of the things Aristotle noticed was that form was teleological, that is, all form seems to have an end in mind. The seed had the mature plant or tree, and the child had the adult. Form came to matter and made a substance, but this substance was not static but changing and growing or, in other words, moving. Aristotle also noticed that everything that was moving had to have a cause, something that started it moving. Seeds had to come from a fully-grown plant, babies had to have parents. In many ways Aristotle was noticing the old chicken and the egg question: Which came first? Well, you could keep proposing causes but eventually you have to get to the first cause. But for the first cause to be uncaused itself, it would have had to be eternal and with no need to be set in motion. It would have to already be fully perfect with no need to realize its potential. Without motion (becoming), it had to cause motion, and thus Aristotle felt the logical necessity to propose his famous Unmoved Mover, that first principle and perfect and immaterial form. This form was the only form not united with matter, but instead standing outside matter to start it all off. This was the closest Aristotle came to saying there was a God. But this is not the personal and loving God of the Bible and religion, rather this is an impersonal mysterious force, perhaps more like the Chinese Tao. Aristotle also came from a perspective where the Earth was the center of the universe. In his understanding, the Unmoved Mover set the heavens in motion. Each of the spheres set the one below it in motion all the way down to Earth and all its motion (not to be confused with rotation which was not understood, but with growth and change). Thinking this all the way to its conclusion one can see that all the changes on Earth are being caused by the heavenly spheres, which in turn are caused by the Unmoved Mover. In this sense, Aristotle showed us what he saw as the role of the philosopher: “to move from the material causes of things, as in natural philosophy, to the formal and final causes, as in divine philosophy, and thus to discover the intelligible essence of the universe and the purpose behind all change” (Tarnas, p.66). Suddenly, despite Aristotle’s very different methodology, science rather than dialectic, he comes very close to Plato’s idea of the philosopher being the one who unites with the world of Ideas. What Is the Good? Another area where we can see Plato and Aristotle’s differences is in the important area of ethics. Plato felt that we had to have knowledge of the transcendent Idea of the Good to in fact be good and know what the good in any particular situation is. But Aristotle did not feel that we could know this. As we saw, he did not believe in separate, transcendent Ideas, and therefore, they could not be known. All you could know were specific examples of good actions by specific good people. From looking at all these various examples, you could develop some general rules, but they would not share the absolute status that Plato sought to find. Aristotle agreed with Plato that virtue was necessary for a happy life. But that virtue was to be found in concrete situations. It would also never be definite, but always a work in progress. From studying various rules of conduct and from looking at the experience of others, Aristotle arrived at his definition of good. Unlike Plato’s absolute good, Aristotle defined the good as the middle of two extremes. The idea was to seek a balance. Courage, for example, was found somewhere in between giving into fear on the one hand, and false bravado on the other hand. But the important difference is that ethics can only be discovered in concrete situations, and your only “absolute” is past experience reflected upon by the mind’s power of reason. And thus, we can see in Plato and Aristotle the birth of two streams of thought, two ways of approaching the world that will continue to wind their way, sometimes close together, and sometimes further apart, all through Western history. Aristotle founded his own school in Athens – the Lyceum. This school was much more a scientific research center and collecting museum. It had an entirely different feel than the mystical and fervent atmosphere at Plato’s Academy. And yet, both schools existed in Athens together, and what is most important for us to remember today, both schools were seeking for the truth, each in their own way. Summary Most of us could put ourselves down as either Platonic or Aristotelian thinkers. That is, the rationalist tends to believe that truth can be found with the mind, while the empiricists believe that truth can be found through the senses. In reality we are probably a little of both, but we have a tendency to lean in one direction or another. And in this sense Western thought can often be divided up in the same way, transcendent or immanent, the Cartesians and the Romantics, the ideal and the practical. Of course the integral way would be to include more rather than less, and to think in terms of both/and rather than either/or. So, what can we conclude from not only this brief look at Aristotle, but looking at this whole unit starting with Socrates and including Plato? Is there a Greek legacy that has forever influenced our Western heritage? Absolutely! “The Greeks were perhaps the first to see the world as a question to be answered. They were peculiarly gripped by the passion to understand, to penetrate the uncertain flux of phenomena and grasp a deeper truth. And they established a dynamic tradition of critical thought to pursue that quest. With the birth of that tradition and that quest came the birth of the Western mind” (Tarnas, p. 69). 1. The universe is lawful and intelligent and humans have a share in that intelligence. Because of this, it is possible to learn about the nature of reality. 2. This truth can be discovered through the use of critical thinking, both by following the laws of logic, and through the dialectical method. But the use of the mind must be checked by close observation and empirical research. 3. On the one hand, the pursuit of philosophy reveals a reality that transcends ordinary reality of change and flux. This is the world of absolutes. On the other hand, the study of nature reveals a world of observable phenomena that must not be mixed up with a mythological conception of gods made in the image of men. 4. Any comprehensive intellectual model of human and cosmic reality must be grounded in verifiable facts and evidence, rather than a belief system. Our understanding must be open to reevaluation and criticism. 5. The very process of seeking the meaning of this world, our reality, brings not only intellectual answers, but also spiritual fulfillment. Philosophy is the love of wisdom. That is the Greek heritage. To reach our potential we need to love the world of ideas. If we are an acorn, what is our oak tree? What is our happiness? Aristotle defined happiness as “an activity of the soul in accordance with virtue.” And what is this activity of the soul? It is a life of wonder and contemplation. Happiness is being a philosopher! I wish you all a Socratic day!
