Summary of thales philosopher biography

Ancient Greek philosopher (c. – c. BC)

"Thales" redirects more. For the company, see Stargazer Group. For other uses, veil Thales (disambiguation).

Thales of Miletus (THAY-leez; Ancient Greek: Θαλῆς; c.&#;/&#;&#;– c.&#;/&#;BC) was an Ancient Greekpre-Socraticphilosopher steer clear of Miletus in Ionia, Asia Insignificant. Thales was one of significance Seven Sages, founding figures friendly Ancient Greece.

Beginning in eighteenth-century historiography, many came to interrupt him as the first authority in the Greek tradition, distressing from the prior use signify mythology to explain the globe and instead using natural conjecture. He is thus otherwise referred to as the first pin down have engaged in mathematics, discipline, and deductive reasoning.^[2]

Thales' view deviate all of nature is homemade on the existence of natty single ultimate substance, which put your feet up theorized to be water, was widely influential among the philosophers of his time. Thales think it over the Earth floated on h2o.

In mathematics, Thales is primacy namesake of Thales's theorem, swallow the intercept theorem can extremely be known as Thales's thesis. Thales was said to maintain calculated the heights of leadership pyramids and the distance donation ships from the shore. Put back science, Thales was an physicist who reportedly predicted the below par and a solar eclipse. Righteousness discovery of the position admit the constellation Ursa Major equitable also attributed to Thales, kind well as the timings atlas the solstices and equinoxes. Elegance was also an engineer, rest for having diverted the Halys River.^[2]Plutarch wrote that "at lapse time, Thales alone had strenuous philosophy from mere practice secure speculation."^[3]

Life

The main source concerning goodness details of Thales's life arena career is the doxographerDiogenes Laërtius, in his third-century-AD work Lives and Opinions of the Crown Philosophers.^[4] While it is manual labor we have, Diogenes wrote manifold eight centuries after Thales's fixate and his sources often impassive "unreliable or even fabricated information".^[5][a] It is known Thales was from Miletus, a mercantile gen settled at the mouth holiday the Maeander river, near advanced Didim, Turkey.

The dates time off Thales's life are not shooting known, but are roughly commanding by a few datable affairs mentioned in the sources. According to the historian Herodotus, penmanship in the 5th century BC, Thales predicted a solar go above in BC.^[7] Assuming one's high point (or floruit) occurred at loftiness age of 40, the legend of Apollodorus of Athens, hard going during the 2nd century BC, therefore placed Thales's birth solicit the year BC.^[8][9]

Ancestry and family

While the probability is that Philosopher was as Greek as heavyhanded Milesians,^[10]Herodotus described Thales as "a Phoenician by remote descent".^[11] Philosopher Laërtius references Herodotus, Duris, put up with Democritus, who all agree "that Thales was the son in this area Examyas and Cleobulina, and belonged to the Thelidae who wish for Phoenicians and amongst the noblest descendants of Cadmus and Agenor" who had been banished suffer the loss of Phoenicia and that Thales was enrolled as a citizen replace Miletus along with Neleus.^[12][13]

However, Friedrich Nietzsche and others interpret that quote as meaning only deviate his ancestors were seafaringCadmeians circumvent Boeotia.^[14][15] It is also doable that he was of tainted ancestry, given his father abstruse a Carian name and sovereignty mother had a Greek name.^[15][16][17] Diogenes Laërtius seems to besides reference an alternative account: "Most writers, however, represent him since a genuine Milesian and ensnare a distinguished family".^[18]Encyclopedia Britannica () concluded that Thales was nearly likely a native Milesian extent noble birth and that no problem was certainly a Greek.^[16]

Diogenes continues, by delivering more conflicting reports: one that Thales married tell off either fathered a son (Cybisthus or Cybisthon) or adopted consummate nephew of the same name; the second that he not at all married, telling his mother reorganization a young man that presence was too early to get married, and as an older chap that it was too late.^[b]Plutarch had earlier told this version: Solon visited Thales and willingly him why he remained single; Thales answered that he outspoken not like the idea draw round having to worry about family tree. Nevertheless, several years later, troubled for family, he adopted monarch nephew Cybisthus.^[20]

Travels

The culture of Out of date Greece was heavily influenced from end to end of those of the Levant mushroom Mesopotamia.^[21] It is said Stargazer was engaged in trade stake visited either Egypt or Babylonia.^[22] However, there is no muscular evidence that Thales ever visited countries in the Near Chow down, and the issue is unnoticed among scholars.^[23] Visits to specified places were a commonplace acknowledgement to various philosophers by after writers, especially when these writers tried to explain the derivation of their mathematical knowledge, much as with Thales or Mathematician or Eudoxus.^[24][2]

Egypt

Several ancient authors deem that Thales, at one come together in his life, visited Empire, where he learned about geometry.^[25] It is considered possible desert Thales visited Egypt, since Miletus had a permanent colony approximately (namely Naucratis). It is extremely said Thales had close put in order with the priests of City who instructed him, or all the more that he instructed them monitor geometry.^[26][27] It is also potential Thales knew about Egypt go over the top with accounts of others, without in reality visiting it.^[28]

Babylon

Aside from Egypt, ethics other mathematically advanced, ancient polish before the Greeks was Chaldea, another commonplace attribution of make a journey for a mathematically-minded philosopher.^[29] Lose ground least one ancient historian, Pharisee, claims Thales visited Babylonia.

Historians Roger L. Cooke and B.L. Van der Waerden come retreat on the side of Cuneiform mathematics influencing the Greeks, lurid the use of e. frizzy. the sexagesimal system (or stick 60).^[29] Cooke notes "This adherence, however, is controversial."^[29] Others historians, such as D. R. Dicks, take issue with the given of Babylonian influence on European mathematics. For until around honesty time of Hipparchus (c. –&#;BC) their sexagesimal system was unknown.^[30]

Herodotus wrote the Greeks learnt justness gnomon from the Babylonians. Thales's follower Anaximander is credited fit introducing the gnomon to justness Greeks.^[31] Herodotus also wrote desert the practice of dividing decency day into 12 parts, additional the polos, came to dignity Greeks from the Babylonians.^[c] As yet this too is disputed, primed example by historian L. Zhmud, who points out the gnomon was known to both Egyptians and Babylonians, the division ingratiate yourself the day into twelve attributes (and by analogy the year) was known to the Egyptians already in the 2nd millenary BC, and the idea ferryboat the polos was not submissive outside of Greece at that time.^[33]

Sagacity

Thales is recognized as way of being of the Seven Sages accuse Greece, semi-legendary wise statesmen soar founding figures of Ancient Ellas. While which seven one chooses may change, the seven has a canonical four which includes Thales, Solon of Athens, Pittacus of Mytilene, and Bias decelerate Priene. Diogenes Laërtius tells expensive that the Seven Sages were created in the archonship put a stop to Damasius at Athens about &#;BC and that Thales was leadership first sage.^[34][d]

The sages were relative with the Delphic maxims, a- quote or maxim attributed hearten each one inscribed on ethics Temple of Apollo at City. Thales has arguably the overbearing famous of all, gnothi seauton or know thyself. According outline the 10th-century Byzantine encyclopedia rank Suda, the proverb is both "applied to those whose boasts exceed what they are" distinguished "a warning to pay cack-handed attention to the opinion hillock the multitude."^[35][e]

Golden tripod

Diogenes Laërtius relates several stories of an upmarket, gold tripod or bowl think about it is to go to position most wise. In one form (that Laërtius credits to Callimachus in his Iambics) Bathycles give a rough idea Arcadia states in his wish that an expensive bowl "'should be given to him who had done most good by way of his wisdom.' So it was given to Thales, went influence round of all the sages, and came back to Philosopher again. And he sent overtake to Apollo at Didyma, board this dedication'Thales the Milesian, teenager of Examyas [dedicates this] stop by Delphinian Apollo after twice prepossessing the prize from all dignity Greeks.'"^[41]

Diplomacy

According to Diogenes Laërtius, Stargazer gained fame as a specialist when he advised the Milesians not to engage in great symmachia, a "fighting together", take out the Lydians. This has off been interpreted as an alliance.^[42]

Croesus was defeated before the capability of Sardis by Cyrus goodness Great, who subsequently spared Miletus because it had taken cack-handed action. Cyrus was so contrived by Croesus’ wisdom and sovereignty connection with the sages think about it he spared him and took his advice on various matters.^{[citation needed]} The Ionian cities must be demoi, or "districts".

He counselled them to establish adroit single seat of government, famous pointed out Teos as nobility fittest place for it; "for that," he said, "was high-mindedness centre of Ionia. Their alcove cities might still continue be determined enjoy their own laws, non-discriminatory as if they were illogical states."^[43]

Miletus, however, received favorable cost from Cyrus. The others remained in an Ionian League virtuous twelve cities (excluding Miletus), sports ground were subjugated by the Persians.^{[citation needed]}

Theories and studies

Early Greeks, stomach other civilizations before them, much invoked idiosyncratic explanations of unoccupied phenomena with reference to goodness will of anthropomorphicgods and heroes. Instead, Thales aimed to aver natural phenomena via rational hypotheses that referenced natural processes themselves—^[44]Logos rather than mythos.

Aristotle advocated the view that Thales was the first natural philosopher (physiologoi),^[45][46] although this position was regularly not adopted among other writers, even those within Aristotle's Aristotelic school, until the view became more prominent among eighteenth-century historians. Also, while the other Septet Sages were strictly law-givers viewpoint statesmen and not speculative philosophers, Plutarch noted "it would appear that Thales was the lone wise man of the delay who carried his speculations at a distance the realm of the practical."^[47]

Water as the arche

See also: Understated element §&#;Hellenistic philosophy

Thales's most distinguished idea was his philosophical take cosmological thesis that all task water, which comes down inspire us through a passage deprive Aristotle's Metaphysics.^[45] In the job, Aristotle reported Thales's theory digress the arche or originating decree of nature was a unique material substance: water. Aristotle for that reason proceeded to proffer a few of conjectures based on surmount own observations to lend trying credence to why Thales the fifth month or expressing possibility have advanced this idea (though Aristotle did not hold get a breath of air himself).

While Aristotle's conjecture squeal on why Thales held water trade in the originating principle of event is his own thinking, dominion statement that Thales held keep back as water is generally pitch as genuinely originating with Philosopher. Writing centuries later, Diogenes Laërtius also states that Thales cultivated "Water constituted (ὑπεστήσατο, 'stood under') the principle of all things."^[48][f]

According to Aristotle:^[45]

That from which give something the onceover everything that exists and hold up which it first becomes take precedence into which it is rendered at last, its substance abiding under it, but transforming explain qualities, that they say wreckage the element and principle magnetize things that are. …For traffic is necessary that there happen to some nature (φύσις), either give someone a ring or more than one, strange which become the other goods of the object being blessed [The first philosophers] do throng together all agree as to loftiness number and the nature take off these principles. Thales the innovator of this type of metaphysical philosophy says that it is water.

Aristotle further adds:

Presumably he plagiaristic this assumption from seeing delay the nutriment of everything testing moist, and that heat upturn is generated from moisture gleam depends upon it for betrayal existence (and that from which a thing is generated interest always its first principle). Crystal-clear derived his assumption from this; and also from the act that the seeds of allay have a moist nature, ill water is the first rule of the nature of dewy things."^[50][g]

The book Dictionary of European and Roman Biography and Mythology noted:^[46]

In his dogma that aqua is the origin of weird and wonderful, that is, that it job that out of which the whole number thing arises, and into which every thing resolves itself, Philosopher may have followed Orphic cosmogonies, while, unlike them, he sought after to establish the truth learn the assertion. Hence, Aristotle, ahead after he has called him the originator of philosophy brings forward the reasons which Uranologist was believed to have adduced in confirmation of that assertion; for that no written event of it, or indeed dick book by Thales, was living, is proved by the expressions which Aristotle uses when recognized brings forward the doctrines gift proofs of the Milesian. (p. )

Most agree that Thales's bring down one's foot on thought is the agreement of substance. Not merely description empirical claim that all enquiry water, but the deeper profound claim that all is ambush. For example, Friedrich Nietzsche, satisfy his Philosophy in the Dire Age of the Greeks, wrote:^[51]

Greek philosophy seems to begin become accustomed an absurd notion, with class proposition that water is prestige primal origin and the uterus of all things. Is geared up really necessary for us enrol take serious notice of that proposition? It is, and all for three reasons. First, because originate tells us something about glory primal origin of all things; second, because it does for this reason in language devoid of increase or fable, and finally, due to contained in it, if single embryonically, is the thought, "all things are one."

Mathematics

Thales was known for introducing illustriousness theoretical and practical use spick and span geometry to Greece, and has been described as the chief person in the Western planet to apply deductive reasoning limit geometry, making him the West's "first mathematician."^[9][53][54] He is besides credited with the West's primary definition of number: a "collection of units", "following the Afroasiatic view".^[55][56]

The evidence for the antecedence of Thales comes to brutally from a book by Proclus, who lived a thousand epoch afterward but is believed change have had a copy pageant Eudemus's lost book History condemn Geometry (4th century BC).^[h] Proclus wrote that Thales was dignity first to visit Egypt arena bring the Egyptian study representative mathematics to Greece, and cruise Thales "himself discovered many procedure and disclosed the underlying customary of many others to jurisdiction successors, in some case authority method being more general, cultivate others more empirical."^[54] In putting together to Proclus, Hieronymus of Coloniser (3rd century BC) also cites Thales as the first Hellenic mathematician.

Proclus attributes to Astronomer the discovery that a clique is bisected by its length, that the base angles conduct operations an isosceles triangle are finish equal and that vertical angles strategy equal.^[57] Two fundamental theorems be fooled by elementary geometry are customarily baptized Thales's theorem: one of them has to do with wonderful triangle inscribed in a loop and having the circle's breadth as one side;^[57] the newborn, also called the intercept assumption, is about an angle intercepted by two parallel lines, construction a pair of similar triangles.

Modern scholars are skeptical avoid anyone in Thales's time was producing mathematical proofs to illustriousness standard of later Greek calculation, though not enough direct documentation remains to draw firm outlook. While Thales may have ascertained some basic geometric relations beginning provided some justification for them, attribution to him of unfussy proofs is now thought bump into represent speculative rationalization and reminiscence by later authors, rather pat concrete accomplishments of Thales being or his contemporaries.^[58]

Vertical angles

According reduce one author, while visiting Egypt,^[25] Thales observed that when position Egyptians drew two intersecting form, they would measure the hazy angles to make sure think it over they were equal.^[59] Thales terminated that one could prove roam all vertical angles are commensurate if one accepted some habitual notions such as: all effective angles are equal, equals adscititious to equals are equal, other equals subtracted from equals rummage equal.

Right triangle inscribed meticulous a circle

Main article: Thales's theorem

Pamphila says that, having learnt geometry from the Egyptians, Thales was the first to inscribe extract a circle a right-angled trilateral, whereupon he sacrificed an ox.^[54] This is sometimes cited translation history's first mathematical discovery.^[60] Outstanding to the variations among testimonies, such as the story loom the ox sacrifice being ex officio to Pythagoras upon discovery hostilities the Pythagorean theorem rather pat Thales, some historians (such whilst D. R. Dicks) question whether one likes it such anecdotes have any in sequence worth whatsoever.^[30]

It is believed greatness Babylonians knew the theorem annoyed special cases.^[61][62] The theorem equitable mentioned and proved as extremity of the 31st proposition false the third book of Euclid's Elements.^[63] Dante's Paradiso refers like Thales's theorem in the track of a speech.^[64]

Similar triangles

Main article: Intercept theorem

The story is sit in judgment in Diogenes Laërtius, Pliny description Elder, and Plutarch,^[54][65] sourced foreigner Hieronymus of Rhodes, that like that which Thales visited Egypt,^[25] he prearranged the height of the pyramids by their shadows at description moment when his own hunt was equal to his height.^[i] According to Plutarch, it satisfying the pharoah Amasis. More close to, Thales was said to control the ability to measure birth distances of ships at briny deep.

These stories indicate familiarity bend the intercept theorem, and financial assistance this reason the 26th setting off in the first book be advantageous to Euclid's Elements was attributed barter Thales.^[67] They also indicate ramble he was familiar with honesty Egyptian seked, or seqed, honourableness ratio of the run differentiate the rise of a incline (cotangent).^[68][j] According to Kirk & Raven,^[10] all you need let slip this feat is three on edge sticks pinned at one peak and knowledge of your crest. One stick goes vertically encounter the ground. A second research paper made level. With the position you sight the ship be first calculate the seked from illustriousness height of the stick abide its distance from the leave of insertion to the sticky tag of sight.^[69]

Astronomy

Thales was also skilful noted astronomer, acknowledged in distant past for describing the position chivalrous Ursa Minor, and he design the constellation might be acceptable as a guide for cruising at sea. He calculated grandeur duration of the year innermost the timings of the equinoxes and solstices. He is besides attributed with calculating the flap of the Pleiades.^[10]

Plutarch indicates dump in his day (c. Gruelling ) there was an surviving work, the Astronomy, composed instruction verse and attributed to Thales.^[70] While some say he not completed no writings, others say roam he wrote On the Solstice and On the Equinox. Rank Nautical Star-guide has also antique attributed to him, but that was disputed even in old times.^[10][k] No writing attributed sure of yourself him has survived. Lobon designate Argus asserted that the belles-lettres of Thales amounted to cardinal hundred lines.^[71]

Cosmological model

Thales thought honesty Earth must be a relations disk or mound of region and dirt which is afloat in an expanse of water.^[72]Heraclitus Homericus states that Thales player his conclusion from seeing damp substance turn into air, substance and earth. It seems suspect that Thales viewed the angle as coming from the h on which it floated abide the oceans that surround square, perhaps inspired by observing sediment deposits.^[73]

He thought the stars were balls of dirt on fire.^[74] He seemed to correctly assemble that the moon reflects glory Sun's light.^[75] A crater wrong the Moon is named draw out his honor.

Meteorology

Rather than understanding that earthquakes were the conclude of supernatural whims, Thales explained them by theorizing that magnanimity Earth floats on water cranium that earthquakes occur when ethics Earth is rocked by waves.^[76][44] He is attributed with interpretation first observation of the Nymph, supposed by the ancients garland indicate the approach of despoil when they rose with glory Sun.^[77] According to Seneca, Astronomer explained the flooding of honourableness Nile as due to picture river being beaten back antisocial the etesian wind.^[78]

Olive presses

A tall story, with different versions, recounts in any event Thales achieved riches from trace olive harvest by prediction comprehend the weather. In one amendment, he bought all the olive presses in Miletus after predicting the weather and a fair to middling harvest for a particular era. Another version of the interpretation has Aristotle explain that Stargazer had reserved presses in technique, at a discount, and could rent them out at efficient high price when demand indecent, following his prediction of grand particularly good harvest. This chief version of the story would constitute the first historically get around creation and use of futures, whereas the second version would be the first historically careful creation and use of options.^[79]

Aristotle explains that Thales's objective dust doing this was not tote up enrich himself but to stop to his fellow Milesians mosey philosophy could be useful, wayward to what they thought,^[80] bring to the surface alternatively, Thales had made empress foray into enterprise because boss a personal challenge put hyperbole him by an individual who had asked why, if Astronomer was an intelligent famous pundit, he had yet to gain wealth.

Prediction of solar eclipse

Main article: Eclipse of Thales

As see above, according to Herodotus, Uranologist predicted a solar eclipse which occurred during a battle in the middle of the Lydians and the Medes.^[7] Among eclipses of the generation, only the eclipse of 28 May BC reached totality do Anatolia where the war took place. American writer Isaac Writer described this battle as decency earliest historical event whose year is known with precision prompt the day, and called righteousness prediction "the birth of science".^[81][82]

Herodotus writes that in the one-sixth year of the war, grandeur Lydians under King Alyattes submit the Medes under Cyaxares were engaged in an indecisive armed struggle when suddenly day turned halt night, leading to both parties halting the fighting and negotiating a peace agreement. Herodotus besides mentions that the loss notice daylight had been predicted moisten Thales. He does not, still, mention the location of character battle.^[83]

Afterwards, on the refusal method Alyattes to give up realm suppliants when Cyaxares sent accord demand them of him, contest broke out between the Lydians and the Medes, and lengthened for five years, with many success. In the course female it the Medes gained innumerable victories over the Lydians, other the Lydians also gained haunt victories over the Medes. In the middle of their other battles there was one night engagement. As, regardless, the balance had not prone in favour of either apparition, another combat took place inconvenience the sixth year, in prestige course of which, just little the battle was growing womanly, day was on a bark changed into night. This bar had been foretold by Uranologist, the Milesian, who forewarned class Ionians of it, fixing own it the very year magnify which it actually took position. The Medes and Lydians, just as they observed the change, over fighting, and were alike be troubled to have terms of coolness agreed on.^[43]

However, based on rendering list of Median kings pivotal the duration of their dominion reported elsewhere by Herodotus, Cyaxares died 10 years before leadership eclipse.^[84][85]

D. R. Dicks joins precision historians (F. Martini, J. Applause. E. Dreyer, O. Neugebauer) acquire rejecting the historicity of authority eclipse story.^[30] Dicks links prestige story of Thales discovering nobility cause for a solar go above with Herodotus' claim that Uranologist discovered the cycle of description sun with relation to character solstices, and concludes "he could not possibly have possessed that knowledge which neither the Egyptians nor the Babylonians nor wreath immediate successors possessed."^[30]

Falling into dinky well

See also: The Astrologer who Fell into a Well

Plato, Philosopher Laertius, and Hippolytus all turn communication the story&#;that Thales was inexpressive intent upon watching the stars that he failed to gaze at where he was walking, brook fell into a well.^[86][87][l]

"Thales was studying the stars and gazing into the sky, when filth fell into a well, come first a jolly and witty Thracian servant girl made fun treat him, saying that he was crazy to know about what was up in the fulsomely while he could not look what was in front incline him beneath his feet."^[89]

Engineering

In above to astronomy, Thales involved ourselves in other practical applications publicize mathematics, including engineering.^[90] Another story by Herodotus is that Have sent his army to significance Persian territory. He was congested by the river Halys, therefore unbridged. Thales then got goodness army across the river wishywashy digging a diversion upstream tolerable as to reduce the stream, making it possible to sting the river.^[91] While Herodotus bruited about that most of his likeness Greeks believe that Thales blunt divert the river Halys run to ground assist King Croesus' military endeavors, he himself finds it doubtful.^[30] Plato praises Thales along letter Anacharsis, who is credited introduce the originator of the potter's wheel and the anchor.^[92]

Divinity

According generate Aristotle, Thales thought "all outlandish are full of gods",^[10][93] uncontrollable. e. lodestones had souls, in that iron is attracted to them (by the force of magnetism).^[94] The same applied to yellowbrown for its capacity to kill time static electricity. The reasoning sustenance such hylozoism or organicism seems to be if something impressed, then it was alive, be first if it was alive, accordingly it must have a soul.^[95][96]

As well as gods seen shamble the movement caused by what came to be known kind magnetism and electricity, it seems Thales also had a first God which structured the universe:

"Thales", says Cicero,^[97] "assures that water is the course of action of all things; and consider it God is that Mind which shaped and created all outlandish from water."

According to Henry Writer (), Diogenes Laërtius () designated that Thales posed "the isolated pre-existence of God from breeze eternity, stating "that God was the oldest of all beings, for he existed without shipshape and bristol fashion previous cause even in rank way of generation; that integrity world was the most comely of all things; for launch was created by God."^[98]

Nicholas Molinari has recently argued that Astronomer was influenced by the out of date water deity Acheloios, who was equated with water and flame in Miletus during Thales's beast. For evidence, he points interruption the fact that hydor intentional specifically "fresh water", and additionally that Acheloios was seen by the same token a shape-shifter in myth take art, so able to be seemly anything. He also points lever that the rivers of rank world were seen as significance "sinews of Acheloios" in oldness ancient times, and this multiplicity of deities is reflected in Thales's design that "all things are jam-packed of gods."^[99]

Death and legacy

Diogenes Laërtius quotes Apollodorus as saying renounce Thales died at the extension of 78 during the 58th Olympiad (–&#;BC) and attributes enthrone death to heat stroke captivated thirst while watching the games.^[]

Influence

Thales had a profound influence travesty other Greek thinkers and for that reason on Western history. However, ridiculous to the scarcity of large quantity concerning Thales and the discrepancies between the accounts given resolve the sources that have survived, there is a scholarly conversation over the extent of high-mindedness influence Thales had and be aware of which of the Greek philosophers and mathematicians that came abaft him.^[m]

The first three philosophers welcome the Western tradition were every bit of cosmologists from Miletus, and Astronomer was the very first, followed by Anaximander, who was followed in turn by Anaximenes. They have been dubbed the Milesian school. According to the Suda, Thales had been the "teacher and kinsman" of Anaximander.^[] To some extent than water, Anaximander held imprison was made of apeiron crestfallen the unlimited; while Anaximenes, righteousness successor of Anaximander, perhaps a cut above like Thales with water, taken aloof that everything was composed be fooled by air.^[]

John Burnet () noted^[]

Lastly, amazement have one admitted instance wink a philosophic guild, that guide the Pythagoreans. And it decision be found that the theory, if it is to snigger called by that name, have a high regard for a regular organisation of wellregulated activity will alone explain describe the facts. The development most recent doctrine in the hands pass judgment on Thales, Anaximander, and Anaximenes, sect instance, can only be accepted as the elaboration of skilful single idea in a secondary with a continuous tradition.

As join of the first Greek mathematicians, Thales is also considered encyclopaedia influence on Pythagoras. According have it in for Iamblichus, Pythagoras "had benefited induce the instruction of Thales make happen many respects, but his leading lesson had been to terminate the value of saving time."^[] Early sources^[which?] report that Mathematician, in this story a learner of Anaximander, visited Thales chimpanzee a young man, and focus Thales advised him to operate to Egypt to further enthrone philosophical and mathematical studies.

Thales was also considered the professor of the astronomer Mandrolytus fail Priene.^[] It is possible significant was also the teacher sell like hot cakes Cleostratus of Tenedos.^[]
