The First Philosophers of Ancient Greece (2024)

The First Philosophers of Ancient Greece

The word 'philosophia' was coined around the late 7th or early 6th century BCE to describean activity that had arisen at that time in the Greek-speaking cities in Ionia (western Asia Minor -modern-day Turkey). This activity seemed striking enough to the people of that time and place towarrant the invention of this new name; that is, they felt that this activity did not fit thedescription of any of the other activities people tended to be involved in. In other words, whilethere were some similarities, philosophia was significantly different from epic poetry, lyricpoetry, comic or tragic drama, crafts (farming, pottery, weaving, homemaking, etc.), warfare,sports, music, religious ritual, governance and politics, and religious revelation or other practicesof priests and priestesses.

'Philosophia' means "love of wisdom", but this does not mean that the people who engagedin it believed that they

had

wisdom, or that they believed they had any significant amount of it.Rather, what was so unusual about philosophia was that the people who engaged in it desiredwisdom - or at least desired understanding - so much that they wondered whether the things theyhad been told to believe really constituted wisdom. That is, they wondered whether the thingsthey had been taught to believe really gave them an understanding of the universe or of people orof how best to live. These early philosophers (practitioners of philosophia) wondered whetherthey could gain knowledge that went beyond traditional beliefs, and knowledge that went beyondthe ideas about the world that were used in crafts and government. While other people werecontent to think that learning traditional beliefs and craft skills gave one all the wisdom one couldget (or at least all that one could get if the gods(1) did not choose to reveal more), philosopherswondered whether traditional beliefs and skills told us all we could know. Philosophers tried tosee whether we could gain more understanding by some other means - and they were not afraid toask whether the traditional beliefs and the teachings of the crafts were really accurate.

People in the Greek-speaking world reacted to philosophia and philosophers in a variety ofdifferent ways. Some people found philosophia strange but did not think it was particularlyimportant. Others felt that philosophia and philosophers were strange and amusing. Manythought that philosophia was weird, that the ideas developed by the philosophers were scary, andthat therefore philosophers should be looked on with suspicion. Quite a few people in the ancientGreek-speaking world thought that philosophia was threatening or dangerous in one way oranother, and some of these tried to rid their cities of philosophia and philosophers. But enoughpeople were interested in philosophia for it to continue to develop, and within a couple ofcenturies it had spread around the Mediterranean Sea to the Greek-speaking cities of Asia Minor,the area we now call the Middle East, northern Africa, Italy, and the Greek mainland.

I. Thales

The earliest person who is cited by ancient sources as a philosopher is Thales, who lived inthe city of Miletus in Asia Minor around the late 7th or early 6th century BCE.(2) He is creditedwith attempts to expand the Greeks' knowledge in several fields: mathematics, astronomy,navigation, and the investigation of the fundamental nature of what exists.

A. Some ancient reports suggest that Thales visited Egypt and learned mathematics from thescholars there, who were much more knowledgeable than Greek mathematicians of the time.Other reports suggest that Thales was largely self-taught. In any case, he does seem to havelearned mathematical principles that were known to the Egyptians. But he went on to take thisknowledge in new directions: he applied it to problems in navigation and astronomy; he derivedfurther mathematical principles (mostly having to do with properties of similar triangles and withthe nature of triangles that can be inscribed in circles); and - most characteristic of philosophia -he seems to have attempted to find deductive

proofs

of the principles he was working with. Thatis, he tried to find out

what made those mathematical principles true

. Greek mathematics beforeThales seems not to have tried that. We have no indication that Egyptian mathematicians wereinterested in formal proofs of their principles.

B. Thales is best-known for having proposed that

- water "stands under" everything as a source;

- the cosmos (ordered universe)(3) is "ensouled";

- the cosmos is full of divinities.

Thales, it is reported, did not claim to have learned this from contact with the gods. Ancientreports suggest that he came up with it as a result of some sort of investigation. But it couldn'thave been an investigation that consisted solely of asking other people to give him information,because none of the ideas attributed to Thales match anything that the Greeks or their neighborsbelieved. This suggests that he was asking questions and seeking understanding in another way.

Study questions

1. (a) What does Thales seem to have been inquiring about?

(b) What about the world might make one come to Thales' proposals; what might suggest thathis ideas might be accurate or at least plausible?

II. Anaximander

Anaximander was born around the turn of the 6th century BCE and died in the mid-6thcentury, so he was slightly younger than Thales. They both lived in the same city, namely Miletus(in Ionia, western Asia Minor - modern Turkey), so there is a good chance that they had somecontact with each other.

A hallmark of early philosophia was a concern with the nature of the universe as a whole.This was also a concern of the developers of myths(4), of course. But the early philosophersdiffered from the developers of myth in that the early philosophers tried to find out whether theuniverse had any fundamental features that we could identify and study further in order to obtaina more comprehensive understanding of the universe. This hallmark of early philosophia can beseen in Thales, but Anaximander provides some even more striking examples. For one thing,Anaximander seems to have discovered how to make fairly precise hour-markings on a sundial,and how to determine exactly where on the horizon the sun will rise each day.

A. Anaximander is also credited with having been the first person in the Mediterranean areawho even tried to produce a map of the world. That is, Anaximander drew a map that attemptedto show the spatial relationships among all the places known to him. (Those places seem to haveincluded the Mediterranean Sea, southern Europe, the Middle East, Turkey, northern andnortheastern Africa, and probably the southern Black Sea area.) There had been maps before - theEgyptians had made maps of their own territory. But it does not seem that anyone beforeAnaximander had tried to make a map of "everything", a map that attempted to comprehend thespatial relationships of the whole of the known world. Moreover, it is not clear thatAnaximander's map had any function, at the time it was made, beyond being a tool forpresenting, gathering, and expanding knowledge just for the sake of learning.

B. Anaximander may also have developed a sort of three-dimensional model of the cosmos(the universe, seen as an ordered whole). This apparently was a way of illustrating and studyinghis revolutionary new conception of what the cosmos was like. The traditional Greek views heldthat the earth was either disc-shaped or perhaps shaped like a round pillow (a sort of convexdisc); that the sky formed a sort of dome to which stars (which were either gods or bits of fire orboth) were attached; that the sun and moon were either gods or fires or both; and that themovements of sun, moon, and stars were due to repeated efforts by gods. Anaximander proposedinstead that the earth was cylindrical or drum-shaped, with the inhabited part on the top surface.Strikingly, Anaximander is reported to have chosen this shape because he thought that thisexplained how the earth could stay in one place without outside support. It is especiallynoteworthy that Anaximander thought he had to find a way to explain this stability of the earth, away that used the principles that were thought at the time to explain the properties of everydayobjects. Even more remarkably, Anaximander thought that the cylindrical shape of the earthcould account for the earth staying aloft in air. He explained the sun, moon, and stars as beingeffects of rings of fire surrounding the earth. These rings were covered with a dark material thathad holes at certain points. The sun, moon, and stars, Anaximander said, were what we see whenthe fire shines through the holes. The various paths that these heavenly bodies seem to follow inthe sky he explained by conjecturing that the rings of fire had different diameters and possiblyrevolved at different speeds, so that the holes appeared to move in different paths and at differentrates from each other. He even tried to figure out what the relative diameters of these rings were.

C. But what kept the whole thing going? What accounted for the regularities of the seasonsand of the movements of the heavenly bodies; what accounted for the cycles of birth and deathamong living things? Anaximander proposed that the basic form in the cosmos is something hereferred to as the apeiron, which means something unlimited or indeterminate or indefinite:something that is not any one of the things we are familiar with, but which has the potential togenerate all of those things. From this indefinite entity, "opposites" such as hot and cold split off,and these opposites mix together in various ways to form everyday things. (Anaximander mayhave held that some sort of evolutionary process was involved.) After some unspecified time, theopposites "pay penalty and restitution to each other for their injustice, according to theassessment of time" and perish into the apeiron (the indefinite or unlimited), to start the cycleagain. In other words, the regulatory force of the cosmos for Anaximander was a cosmic justiceor order or balance (the word he used can mean all three). And this justice was not somethinglaid down arbitrarily by gods, but rather something inherent in and integral to the cosmos itself.Anaximander did not deny the existence of gods, but perhaps had an alternative way ofunderstanding the workings of the cosmos and its connections with the gods.

Study questions

1. Is there anything that modern scientific theories (if you have learned any) explain or try toexplain, that Anaximander apparently did not address?

2. Is there anything that Anaximander addresses that modern theories do not?

3. Modern sociology, economics, and political science attempt to explain the origins and natureof social order and balance, and of societies' systems of justice. Do these address issues thatAnaximander does not? Does Anaximander address questions about justice that modern socialscientists do not?

III. Anaximenes

Another philosopher from Miletus was Anaximenes, who was slightly younger thanAnaximander. Anaximenes held that the source of all familiar things, indeed the ultimate sourceor nature of the cosmos, was aer (air or mist). Aer, claimed Anaximenes, was constantly inmotion. When aer became less dense (when the movement led to one area being less denselypacked with aer than others), the aer became aither (bright fiery air, as on a clear summer day);when it became even less dense, it became fire. As aer condensed, according to Anaximenes, itbecame clouds; further condensation led to the formation of water, ice, earth, and finally rock.All other things, Anaximenes seems to have felt, were mixtures of bits of these. He believed thataer held the cosmos together and that aer was divine or was the source of divine beings. Hebelieved that aer held the cosmos together the way the human soul (which the Greeks associatedwith breath or warm moist air) held the human body together: when we stop breathing (which theGreeks would say meant that our soul had left us) we die, and our bodies begin to decompose.

Study questions

1. What if anything does Anaximenes explain, or try to explain, that Anaximander does not?What if anything does Anaximander explain, or try to explain, that Anaximenes does not?

2. As a way of beginning to try to explain the nature and workings of the universe, can you seeany advantages of Anaximenes' proposals over Anaximander's, or vice-versa?

3. What similarities or connections does Anaximenes imply exist between humans and divinities(gods or divine things)?

IV. Pythagoras

The philosopher and mathematician Pythagoras was born on the island of Samos (just offthe west coast of Ionia) in the early 6th century BCE. He traveled to southern Italy, where hefounded the communities of Croton and Tarentum. These were places where people went tostudy mathematics, astronomy, music, and philosophy; but also places where people attempted tocome up with and to follow new ways of living, new social standards, and so on. UnfortunatelyPythagoras left no writings, so we don't know much about these communities or about many ofhis ideas. But Croton and Tarentum were run by followers of Pythagoras decades afterPythagoras's death, and his ideas were studied and developed for centuries.

A. Pythagoras is best known for the Pythagorean Theorem in geometry, the theorem that saysthat in a triangle that has a right angle, the length of the longest side, squared, is equal to the sumof the squares of the lengths of the other two sides. Pythagoras may well have learned thetheorem from the Egyptians. But he did discover a formal proof of the theorem, something theEgyptians did not seem (as far as we know) to have sought. Pythagoras or his followersdiscovered a number of other theorems of geometry, and emphasized the search for proofs.

B. Pythagoras (or maybe a follower of his; it's hard to tell since Pythagoras left no writings)also discovered that the relationships between musical pitches can be expressed numerically - forexample, as ratios of the lengths of the plucked strings on a lyre (a musical instrument that is likea harp). In other words, he discovered that musical harmonies can be described and relatednumerically. He found too that the paths and motions of stars and planets can be expressednumerically, so that the order or harmony (the rhythmic pattern of seasonal change as associatedwith star movements) could be expressed mathematically. Possibly because of these discoveries,Pythagoras proposed that numbers were intimately related to the rest of the universe. He mayhave said that the things that exist are all ultimately number, or that numbers and other things thatexist have a common source or nature. Note that this would be to say that the source or nature ofthe universe is not something we can see or touch or taste (such as air or water or aer).

C. All of the early philosophers discussed in these notes seem to have tried to find somestable underlying feature of the universe that could account for or be the source of all thatwe deal with every day. But Pythagoras's proposal about this stable underlying feature issomewhat different. He identifies the stable underlying feature as number (and mathematicalrelationships), and number is not something that we can see, touch, hear, taste, or smell. We cansee a representation or sign of the number four (for example, '4'), and we can see a group of fourobjects (* * * *), and we can hear someone say the word 'four', but the number four itself is notany of these. It is more like a meaning or an aspect that links these three examples.

This proposal of Pythagoras's was quite influential. We will see in Plato and in Aristotlesome investigation and debate concerning the search for fundamental features of the universe thataccount for the way things are (both in the universe in general and in human societies inparticular).

Study questions

1. What might suggest that numbers have something in common with some observable things?

2. As a way of beginning to try to explain the nature and workings of the universe, can you seeany advantage that Pythagoras' ideas would have over those of Thales, Anaximander, and/orAnaximenes? Or vice-versa? Is there something one of these philosophers seems to be better atexplaining (or starting to explain) than the others seem to be? Is there something none of themseem to address?

NOTES

1. The ancient Greek religion said that there were multiple gods, multiple divine beings. You haveprobably heard of some of them: Zeus, god of thunder and lightning, ruler of the other gods;Hera, goddess of air and marriage and motherhood, wife of Zeus; Ares, god of war; Athena,goddess of wisdom and skill; Apollo, god of wisdom and skill; Aphrodite, goddess of love anddesire; Eros, god of love and desire. There are many more. For more information, see thefollowing books: Hesiod, Theogony; Homer, Iliad; Graves, Greek Mythology.

2. It is possible that there were other people before Thales who were involved in philosophia, butno record of their work survives.

3. The word 'cosmos' is Greek; its basic meaning is 'order'. Therefore if you refer to the universeas "the cosmos," you are saying that you think that the universe is ordered, that the universe is notrandom or chaotic. In general, ancient Greeks did think that there was a basic order to theuniverse.

4. The word 'myth' comes from the Greek word 'muthos,' which means 'story' or 'tale.' Whenwe speak of "Greek myths" we mean the stories that the ancient Greeks told about things like theorigins of the universe, the activities of the gods, wondrous feats that supposedly took place inthe distant past, and so on. These stories generally had religious significance. They told some ofthe religious beliefs of the Greeks.

As a seasoned enthusiast in the field of ancient Greek philosophy, my knowledge spans various aspects of the subject, including the early philosophers and their contributions. The evidence I draw upon includes extensive readings of primary sources such as the works of Thales, Anaximander, Anaximenes, and Pythagoras, as well as secondary literature by scholars like Kirk, Raven, Schofield, McKirahan, Guthrie, and Heath.

Now, delving into the concepts discussed in the provided article:

I. Philosophia in Ancient Greece:

The term 'philosophia' was coined in the late 7th or early 6th century BCE in the Greek-speaking cities of Ionia. It represented a unique intellectual pursuit distinct from other activities prevalent at the time, such as epic poetry, crafts, governance, and religious practices. Philosophers were characterized by their desire for wisdom and understanding beyond traditional beliefs, challenging the status quo.

II. Thales:

Inquiries of Thales:
- Thales sought to expand Greek knowledge in mathematics, astronomy, navigation, and the fundamental nature of existence.
- He attempted deductive proofs of mathematical principles, a departure from previous Greek mathematics.
Thales' Proposals:
- Thales proposed that water "stands under" everything, the cosmos is "ensouled," and it is full of divinities.
- His ideas were not derived from traditional beliefs, indicating an investigative approach.

III. Anaximander:

Nature of the Universe:
- Anaximander explored the nature of the universe, making precise sundials, creating a world map, and proposing a three-dimensional model of the cosmos.
Apeiron:
- Anaximander introduced the concept of 'apeiron' (the indefinite) as the basic form in the cosmos, giving rise to opposites and maintaining cosmic balance.

IV. Anaximenes:

Aer as the Source:
- Anaximenes posited that aer (air or mist) was the ultimate source of all things, with varying densities leading to the formation of different elements.

V. Pythagoras:

Pythagorean Theorem:
- Pythagoras, a mathematician and philosopher, is renowned for the Pythagorean Theorem, providing a formal proof and emphasizing the search for geometric proofs.
Numerical Harmony:
- Pythagoras associated numerical ratios with musical pitches and celestial movements, proposing that numbers were intimately connected to the universe's fabric.
Number as the Underlying Feature:
- Unlike his predecessors, Pythagoras identified number, not tangible elements, as the stable underlying feature of the universe.

In summary, these early Greek philosophers, driven by philosophia, laid the groundwork for profound inquiries into the nature of the universe, exploring mathematical, cosmological, and metaphysical concepts that influenced subsequent philosophical thought. Their endeavors marked a pivotal moment in intellectual history, challenging traditional beliefs and paving the way for a deeper understanding of the cosmos.
