Aristotle THE GREEK PHILOSOPHER Danny Nielsen | Intro to Philosophy Section Phil 1000-005 | July 29, 2014 Alexander Israilevsky ePortfolio link: dannynielsen.yolasite.com/philosophy.php Aristotle The Greek Philosopher I would like to start off by speaking a little about Aristotle’s life although not much is known about his childhood there is still plenty of interest insights about what we do know about him. Aristotle is my favorite philosopher, in my eyes very successful life in which everyone should strive for. If I could live a life like him I would feel very accomplished and feel as though I have changed civilization as we know it, which is exactly what Aristotle did. He helped form western civilization as we know it today. I hope in this report you have a clear understanding of who Aristotle was, what he did, and what his philosophy was about. Aristotle, whose name interestingly enough means “best purpose”, was born in 384 BC in Stagira northern Greece. His father Nicomachus was the personal physician to King Amyntas of Macedon. At about the age of 18, Aristotle moved to Athens to continue his education at Plato's Academy. He remained there for nearly 20 years before leaving Athens. The supposed story about his departure from Plato’s academy records that he was disappointed with the Academy's decision after Plato passed control of the academy to PAGE 1 his nephew Speusippus, Aristotle thought that was a bad decision because he knew more than Speusippus and thought that he should have control of the academy, although it is also possible that Aristotle feared anti-Macedonian sentiments and left before Plato had died. Aristotle and Plato's friendship has been a strongly debated topic. Plato referred to Aristotle as a reader. When Aristotle left the academy Plato said that “Aristotle rejects us.” Also later Aristotle would criticize many of Plato’s philosophical believes. Although Aristotle owes much of his philosophical believes to Plato. When Aristotle left Athens he accompanied Xenocrates to the court of his friend Hermias of Atarneus in Asia Minor. There, he traveled with Theophrastus to the island of Lesbos, where together they researched wildlife of the island. Aristotle married Pythias, who was either Hermias’s adoptive daughter or niece. They had a daughter together, who was named after her mother Pythias. After the death of his close friend Hermias, Aristotle was invited by Philip II to become the tutor to his son Alexander (The Great). Aristotle was then appointed as the head of the royal academy of Macedon. During that time he gave lessons not only to Alexander, but also to two other future kings: Ptolemyand and Cassander. Aristotle encouraged Alexander toward eastern conquest and his attitude towards Persia was completely one sided. In one example, he counsels Alexander to be a leader to the Greeks and a dictator to the barbarians, to look after the Greeks as friends and relatives, and to deal with the Persians as you would wild beasts or plants. By 335 BC, Aristotle had returned to Athens, establishing his own school there PAGE 2 known as the Lyceum. Aristotle conducted courses at the school for the next twelve years. While in Athens, his wife Pythias died during that time and Aristotle became involved with Herpyllis of Stagira, they had a son whom he named after his father, Nicomachus. He wrote many dialogues of which only fragments have survived. Those works that have survived are in discourse form and were not, for the most part, intended for widespread publication; they are generally thought to be lecture aids for his students. His most important papers include Physics, Metaphysics, Nicomachean Ethics, Politics, De Anima (On the Soul) and Poetics. Aristotle not only studied almost every subject possible at the time, but made significant contributions to most of them. Which to me is why he is one of my favorite philosophers. In physical science, Aristotle studied anatomy, astronomy, embryology, geography, geology, meteorology, physics and zoology. In philosophy, he wrote on aesthetics, ethics, government, metaphysics, politics, economics, psychology, rhetoric and theology. Yes you could say he is a very well educated individual I feel because he loved life and wanted to know is much and help as much as he possibly could. He also studied education, foreign customs, literature and poetry. His combined works constitute a virtual encyclopedia of Greek knowledge. Near the end of his life, Alexander became suspicious and wrote threatening letters to Aristotle. Aristotle had made no secret of his dislike for Alexander's sham of religion and the king had executed Aristotle's grandnephew Callisthenes as a traitor. A widespread tradition in ancient times suspected Aristotle of playing a role in Alexander's PAGE 3 death, but there is little evidence and that is just speculation. Following Alexander's death, anti-Macedonian sentiment in Athens was renewed. In 322 BC, Eurymedon the Hierophant denounced Aristotle for not holding the gods in honor, prompting him to flee to his mother's family estate in Chalcis, explaining: “I will not allow the Athenians to sin twice against philosophy” a reference to Athens's prior trial and execution of Socrates. Aristotle died in Euboea of natural causes later that same year, having named his student Antipater as his chief executor and leaving a will in which he asked to be buried next to his wife. In general, the details of the life of Aristotle are not well-established. The biographies of Aristotle written in ancient times are often speculative and historians only agree on a few significant points. Aristotle’s philosophy is very broad and there is a lot to know about his personal philosophy however I will only be covering his logic and science philosophy in the rest of this report so you will have a better understanding of what he thought about science and logic. Aristotle placed great emphasis in his school on direct observation of nature, and in science he taught that theory must follow fact. He considered philosophy to be the discerning of the self-evident, changeless first principles that form the basis of all knowledge. Logic was for Aristotle the necessary tool of any inquiry, and the conclusion was the system that all logical thought follows. He introduced the idea of category into logic and taught that reality could be classified according to several categories— substance (the primary category), quality, quantity, relation, determination in time and space, action, passion or passivity, position, and condition. PAGE 4 Aristotle also taught that knowledge of a thing, beyond its classification and description, requires an explanation of causality, or why it is. He imagined four causes or principles of explanation: the material cause (the substance of which the thing is made); the formal cause (its design); the efficient cause (its maker or builder); and the final cause (its purpose or function). In modern thought the efficient cause is generally considered the central explanation of a thing, but for Aristotle the final cause was most important. In the larger sense of the word, Aristotle makes philosophy equal with reasoning, which he also would describe as "science". Note, however, that his use of the term science is a different meaning than that covered by the phrase "scientific method". For Aristotle, "all science is either practical, poetical or theoretical". By practical science, he means ethics and politics; by poetical science, he means the study of poetry and the other fine arts; by theoretical science, he means physics, mathematics and metaphysics. In the period between his two stays in Athens, between his times at the Academy and the Lyceum, Aristotle conducted most of the scientific thinking and research for which he is famous today. In fact, most of Aristotle's life was devoted to the study of the objects of natural science. Aristotle's metaphysics contains observations on the nature of numbers but he made no original contributions to mathematics. He did, however, perform original research in the natural sciences, for instance botany, zoology, physics, astronomy, chemistry, meteorology, and several other sciences. At the beginning of the 16th century, scientists began applying mathematics to the PAGE 5 physical sciences, and Aristotle's work in this area was considered inadequate. His failings were largely due to the absence of concepts like mass, velocity, force and temperature. He had a conception of speed and temperature, but no quantitative understanding of them, which was partly due to the absence of basic experimental devices, like clocks and thermometers. Had he had those devices today I’m sure his findings would be a lot more adequate. His writings provide an account of many scientific observations, a mixture of talented guesses and curious errors. For example, in his History of Animals he claimed that human males have more teeth than females. Galileo, showed by simple experiments that Aristotle's theory that a heavier object falls faster than a lighter object is incorrect Aristotle also believed that the earth was the center of the universe. Its true to say in some places, Aristotle goes too far in explaining the 'laws of the universe' from a simple observation. Today's scientific method assumes that such thinking without sufficient facts is ineffective, and that discerning the rationality of one's hypothesis requires far more experimentation than what Aristotle used to support his laws. Aristotle believed that the earth was the center of the universe. Because he was the philosopher most respected by European thinkers during and after the Renaissance, these thinkers often took Aristotle's mistaken positions as given, which held back science in this era. However, Aristotle's scientific shortcomings should not mislead one into forgetting his great advances in the many scientific fields. Although not all his predictions where correct I do admire his willingness to explore the unknown and at least try to explain the unexplained. In that aspect I highly respect Aristotle. PAGE 6
