2 or 3 Things I Know About Thales

Thales correctly predicted a solar eclipse that took place on 28th May, 585 BC.


The dawn of knowledge and truth originated in the ancient Greek city-state of Miletus. The tiny city overlooking the Mediterranean Sea was packed with a number of intellectual minds, who would prove to shape the development of subsequent Western thought. One of the city's most honorable citizen was certainly Thales – widely known as the founder of Western Philosophy.

Thales of Miletus

While Thales was considered intelligent by his contemporaries, I suspect he has ever intended to be a strict philosopher in the first place. Thales was in no way an armchair philosopher, because he was famed for many of the practical achievements he has made in Miletus. With a concentration in astronomy and mathematics, our founder of philosophy used his observations and rational understanding to solve problems of engineering and logistics in ancient Greece. Given the prosperity and efficient communication in Miletus and the other city-states around the 6th century BC, Thales soon became well-known and he was acclaimed as one of the 'Seven Wise Men of Ancient Greece', presumably a significant recognition in his era.

If you want to place blame on the one who discovered this geometric theorem, go after Thales!
Thales and the Eclipse

The legacy of Thales is forever entangled with a famous eclipse that has likely taken place on 28th May, 585 BC. While there exists a number of alternative theories regarding the authenticity of the account, many historical documents have stated that Thales has predicted correctly that a solar eclipse would take place on that fateful day in 585 BC. The eclipse also led to a side-effect : it interrupted a long battle between the Medes and Lydians, and eventually they made peace with each other. While the ingenious speculations by Thales raised a lot of awe, presumably the peace-making effort by the Milesian thinker was unintentional.

While meteorological phenomena are certainly viewed under science's lens, how did people from the 'mythos'-oriented Greece make sense of these natural phenomena? Archilochus, a renowned poet in ancient Greece, made the comment that Zeus has darkened the sun at noon after witnessing an eclipse himself. While the poet's statement sounds corny by today's standard, we cannot blame him. The supernatural and Homeric outlook governed the thinking framework of ancient Greece, and it was up to someone likes Thales to demystify the universe for everyone.

Thales' prediction of the eclipse not only sounded cool to the fellow citizens in Miletus , that feat also represented a turning point for one to understand his world. Thales's achievement likely arose from the fact that he attempted to look for the regular patterns in these observable phenomena that was taking place around him. By discovering the uniformity of nature, Thales tried to understand the events in terms of natural cycles. No, Zeus did not tell Thales beforehand that he planned to darken the sun again to prevent a big brawl on Earth, it was that Thales tried hard to make sense of his world in a naturalistic manner. Therefore Thales was some sort of proto-scientist : his work could be seen as the precursor to empirical science, and the dawn of natural philosophy in the West.

Thales and Water

Thales has also speculated a possible first cause for the universe. He asserted that water was the origin for all things on Earth. This proposal is really primitive and sounds rather outrageous for the standard of today. It was likely that Thales has observed the preponderance of water around Miletus and possibly drew up this conclusion. No matter how ridiculous that might sound, his idea was actually significant in a philosophical point-of-view. Thales’ standpoint represented an example of material monism, meaning that the ultimate reality of the universe consisted of one single material substance. His successors in the Milesian school, Anaximander and Anaximenes, proposed other type of matter instead, and the search for the metaphysical substance of the universe became the preoccupation of many later philosophers, when they developed the First Philosophy of their respective theories.

What did Thales see in these olives? Opportunity for business venture.
Thales and the Olive Press Venture

Some skeptics might say, 'Well, it sounds great to guess an eclipse correctly and have some great speculations, but there is one thing Thales is out of reach – money. How can one admire a wise man who cannot make a living?' Thales proved himself to be the Daniel 'I Drink Your Milkshake' Plainview of his age – and for him the 'milkshake' was olive oil. From his astronomical observation and understanding of the cosmological cycles, Thales hypothesized that there would soon be a great harvest of olives in the coming year. So in advance he rented all the olive presses – the machines required for making olives into olive oil – from the other merchants. In a sense he has got hold of some many of these tools that it could be considered an ancient version of monopoly. There came a beautiful year of olive production, and this precursor to venture capitalism succeeded. All the farmers with the olive harvest had to come to Thales for the olive press, and as a result he made a lot of money from renting out the olive press. To Thales, knowledge led to power indeed!


I should end with a funny anecdote about Thales. When observing the stars in the sky, Thales accidentally fell into a hole with a shallow depth. A girl helped him out and laughed at his folly, stating that he has seen things far away but not things in front of him. While the young lady has certainly provided a worldly advice, she was oblivious to the reason why certain people would eventually shape the history of humanity. Those chosen ones were not acting in command of Zeus – they were just the ones who were willing to look further.
