983 b20), but he became tentative when he proposed reasons which might have justified Thaless decision: [Thaless] supposition may have arisen from observation . I.75). Whether Thales fell into a well, or tripped when he was getting in or out of a well, the story grew up around a mishap. Thales Thales of Miletus was an illustrious pre-Socratic Greek mathematician, astronomer and a philosopher. V.52). Bertrand Russell, the great mathematician and philosopher, is noted as having said that Western philosophy begins with Thales. Thales was one of the Seven Sages of Greece, who were revered by Greeks of the following centuries for their insight and wisdom. 16-17). It traces the development of physics ideas from Thales of Miletus, via Isaac Newton, to the nuclear physics investigations at the beginning of the twentieth century. Thales was not named as a Sage because of any political advice which is extant. What Thales did was to put forward certain propositions which, it seems, he could have proven by induction: he observed the similar results of his calculations: he showed by repeated experiment that his propositions and theorems were correct, and if none of his calculations resulted in contrary outcomes, he probably felt justified in accepting his results as proof. PROPOSITION I.15: If two straight lines cut one another, they make the vertical angles equal to one another (Proclus, 298.12-13). This was reason enough to declare Thales to be a man of great wisdom and to designate him as the first of the Seven Sages of Ancient Greece. Thales was a Milesian philosopher credited with what is often described as the discovery of nature, or the realization of the fact that natural phenomena are explicable in terms of matter interacting according to natural laws. (Metaph. The Ancient Greeks are widely considered to have been the cradle of Western thought, and to have laid the foundations for modern understandings of mathematics, astronomy, and physics. There is no confirmatory statement on how he died. 780 b19-21), and Pliny (HN, II.XI) wrote that: The suns radiance makes the fixed stars invisible in daytime, although they are shining as much as in the night, which becomes manifest at a solar eclipse and also when the star is reflected in a very deep well. The vital points are: Thales foretold a solar eclipse; it did occur within the period he specified. Please refer to the appropriate style manual or other sources if you have any questions. According to Herodotuss report, the umbra of the eclipse of Thales must have passed over the battle field. Damasias was archon in 582/1. >. It is quite likely that Thales was involved in commercial ventures, possibly the export of olive oil, and Plutarch reported that Thales was said to have engaged in trade (Plut. It brought to a halt the battle being fought between Alyattes and the Mede, Cyaxares and, in addition, brought peace to the region after five years of indecisive warfare (Hdt. It was a force within the universe itself. 8 Contributions of Thales of Miletus to Philosophy and Science Ionian school led by Thales of Miletus (c. 624-548 BCE) Pythagorean school led by Pythagoras of Samos (c. 580-500 BCE) Both individuals and their schools were located on the Mediterranean sea Ample opportunity to travel to existing centers of learning Reportedly, both traveled to Egypt and Babylon where they Thales significance lies less in his choice of water as the essential substance than in his attempt to explain nature by the simplification of phenomena and in his search for causes within nature itself rather than in the caprices of anthropomorphic gods. Some commentators and philosophers believe that Thales may have witnessed the solar eclipse of 18th May 603 B.C.E. Euclid (300BC), however, is worthy of discussion. I.37). 405 a20-22); Some think that the soul pervades the whole universe, whence perhaps came Thaless view that everything is full of gods (De An. Thus, his feat was apparently isolated and only approximate; Herodotus spoke of his foretelling the year only. The motive force was not a supernatural being. The common belief was that earthquakes were caused by the rage of the sea-god Poseidon. It was Aristotles opinion that Thales may have observed, that the nurture of all creatures is moist, and that warmth itself is generated from moisture and lives by it; and that from which all things come to be is their first principle (Metaph. However, Herodotus did not accept that story, because he believed that bridges crossed the river at that time (I.74). Herodotus (The Histories, II.156) was impressed when he saw Chemmis, a floating island, about thirty-eight kilometres north-east of Naucratis, the Egyptian trading concession which Thales probably visited. Building on Egyptian and Babylonian knowledge, figures such as Thales of Miletus, Pythagoras, and Aristotle developed ideas in mathematics, astronomy, and logic that would influence Western thought, science, and philosophy for centuries to come. Thales the Philosopher | Theory & Contributions - Study.com Every series in a periodic cycle lasts about 1,300 years and comprises 73 eclipses. IV.9), Lucretius (De Rerum Natura , V.783-808) and Ovid (Met. From observation, it appears that the earth is covered by a dome. In this way, Thales answered those who reproached him for his poverty. 560 bce) and King Cyaxares of Media (reigned 625585 bce), evidently on May 28, 585. Sol. The dates of Thales's life are not exactly known, but are roughly established by a few datable events mentioned in the sources. Proof of the theorem dates from the Elements of Euclid (Proclus, 299.2-5). Required fields are marked *. He was born around 624 BC and died in 545 BC. Within living memory, older Milesians had witnessed the island of Lade increasing in size within the Gulf, and the river banks encroaching into the river to such an extent that at Priene, across the gulf from Miletus the warehouses had to be rebuilt closer to the waters edge. Presocratic Philosophy - Stanford Encyclopedia of Philosophy One may suggest a pattern after witnessing three events that are separated by equal periods of time, but the eclipse which preceded that of 603, and which occurred on 6th May 621, was not visible in Near-Eastern regions. This is how Diogenes Laertius recorded the event: [Thales] seems by some accounts to have been the first to study astronomy, the first to predict eclipses of the sun, and to fix the solstices; so Eudemus in his History of Astronomy. Diogenes asserted that Herodotus knew of Thaless work, and in naming Xenophanes, Heraclitus, and Democritus, he nominated three of the great pre-Socratics, eminent philosophers who were familiar with the work of Thales. The understanding that water could generate into earth is basic to Thaless watery thesis. Because he gave no role to mythical beings, Thaless theories could be refuted. It was only when Aristotle attempted to provide the reasons for the opinions that Thales held, and for the theories that he proposed, that he sometimes displayed caution. The prevailing view at the time was that movement of any kind indicated life, or a soul, or a god. It is an advance upon the traditional Homeric view that they resulted from an angry supernatural god, Poseidon, shaking the earth through his rapid striding. As Aristotle points out, the scheme has universal application, being nothing more than a monopoly. Thaless views were not ancient and primitive. However, the evidence is that the Egyptian skills were in orientation, measurement, and calculation. Metaph. His theories were new, bold, exciting, comprehensible, and possible of explanation. Thales of Miletus (623-540 BC) was a great Greek philosopher and thinker who also dabbled in mathematics, geometry, astronomy and physics. In De Caelo Aristotle wrote: This [opinion that the earth rests on water] is the most ancient explanation which has come down to us, and is attributed to Thales of Miletus (Cael. It is difficult to believe that Thales would not have written down the information he had gathered in his travels, particularly the geometry he investigated in Egypt and his measuring of the height of the pyramid, his hypotheses about nature, and the cause of change. 1091 b9). 17.1.18) on the Canopic mouth of the Nile, and it is possible that Thales visited Egypt on a trading mission. Other Eleatics: Zeno and Melissus 7. Thales of Miletus | Who was, biography, thought, contributions, arche According to Bertrand Russell, "Western philosophy begins with Thales". . Long-term fluctuations in the Earths rotation: 700 BC to AD 1990.. Articles from Britannica Encyclopedias for elementary and high school students. A city called Miletus was home to several Greek philosophers who made significant contributions to physics. From any number of ports Thales could have sought information, and from Sinope he may have ventured on the long journey to Babylonia, perhaps travelling along the valley of the Tigris, as Xenophon did in 401-399 B.C.E. Western philosophy - Thales, Anaximander, and Heracleitus H203). The Milesians, therefore, were an important example of an early culture of rational scientific debate. Even Aristotle regarded him as the first philosopher in Greek tradition. Presocratic Atomism 9. Thales may have envisaged some quality, common to ships and earth, a quality of floatiness, or buoyancy. In other recent research Britton has analysed a text known as Text S, which provides considerable detail and fine analysis of lunar phenomena dating from Nabonassar in 747 B.C.E. Simplicius (Diels, Dox. Through their association they comprised the Milesian School: They all worked on similar problems, the nature of matter and the nature of change, but they each proposed a different material as the primary principle, which indicates that there was no necessity to follow the masters teachings or attribute their discoveries to him. V.14. Diogenes Laertius (I.27) recorded: Pamphila states that, having learnt geometry from the Egyptians, [Thales] was the first to inscribe a right-angled triangle in a circle, whereupon he sacrificed an ox. To Thales water held the potentialities for the nourishment and generation of the entire cosmos. Simple metallurgy had been practised long before Thales presented his hypotheses, so Thales knew that heat could return metals to a liquid state. In Metaphysics (983 b21) Aristotle stated, quite unequivocally: Thales . [4] The Greek philosopher Thales was one such man. Thales and geometry: There is a theorem in geometry called Thales' theorem about similar triangles. His questioning approach to the understanding of heavenly phenomena was the beginning of Greek astronomy. Anaximander | Philosophy, Evolution, & Facts | Britannica He founded the Milesian school of natural philosophy, developed the scientific method, and initiated the first Western enlightenment. 9-10) and followed by Ps.-Plutarch (Epit. Updates? . Patricia OGrady Thales of Miletus | Encyclopedia.com In two works, he asked the question: Why is the angle in a semicircle always a right angle? (An. or. Diogenes recorded that Thales was the first to receive the name of Sage in the archonship of Damasias at Athens, when the term was applied to all the Seven Sages, as Demetrius of Phalerum [born. When Aristotle reported Thaless pronouncement that the primary principle is water, he made a precise statement: Thales says that it [the nature of things] is water (Metaph. The later commentators, Cicero (Nat. Callimachus (D.L. Herodotus recorded the details that he had obtained, but used his own different understanding of the situation to discount the report. Critical discussion implies more than familiarity with other views, and more than mere disagreement with other theories. Thales is considered to be one of the most brilliant mathematicians in history. E&M History - University of Virginia
