No, Thales of Miletos Was Not “the First Scientist”

Thales of Miletos (lived c. 625 – c. 545 BCE, with those dates being very approximate) is widely revered today with monikers such as “the first philosopher,” “the first scientist,” or “the first mathematician.” Many people today admire him, believing that he was an astounding, once-in-a-millennium kind of genius akin to Isaac Newton or Albert Einstein who single-handedly invented the idea of science as we know it. There is even a French defense contracting company named after him called the “Thales Group” (presumably because the name “Thales” makes people think of science, innovation, and progress, which are all much-needed positive associations for a company that actually makes deadly weapons that governments use to kill people).

The Thales of the modern imagination, however, is predominantly a myth. Most of the stories that people have heard about him are legends that can’t possibly be true, that are first attested many centuries after his death, or both. Much like Pythagoras of Samos and Hippokrates of Kos, the historical Thales of Miletos is an obscure figure about whom very little is known with any certainty.

Aristotle Was Not Wrong about Everything

The ancient Greek philosopher Aristotle (lived 384 – 322 BCE) is widely portrayed in popular culture as an overconfident buffoon who made assertions based on no evidence whatsoever and who was wrong about nearly everything. It is often claimed that his errors and overconfidence held back the progress of science for two thousand years. This portrayal is wildly inaccurate and is rooted in a centuries-old tradition of hostile writers deliberately misrepresenting Aristotle’s works to make him look as stupid as possible.

It is undoubtedly true that Aristotle made quite a few mistakes, but he was wrong a lot less often than is usually claimed. Furthermore, Aristotle did, in fact, rely on empirical evidence. In fact, of all ancient Greek philosophers, Aristotle is by far one of the most empirical. When Aristotle did make a mistake, it was generally not because he didn’t care about evidence, but rather because the evidence available to him was incomplete or his interpretation of the evidence was faulty.

Finally, the claim that Aristotle held back the progress of science for two thousand years is demonstrably wrong and ridiculous. For one thing, for much of the two thousand years in question, Aristotle wasn’t even generally seen as the most authoritative philosopher in the parts of the world where his works were being regularly studied. Furthermore, even when Aristotle was seen as the most authoritative philosopher, his authority was still open to some degree of question.

Why Was Aristarchos’s Heliocentric Model Dismissed and Ignored?

Many people are astonished to learn that the concept of heliocentrism did not originate with Nicolaus Copernicus, but rather with the ancient Greek astronomer Aristarchos of Samos (lived c. 310 – c. 230 BC), who published a book in around the early third century BC in which he argued that the Earth orbits around the Sun. This book has not survived, but we know about its existence because it is referenced by later authors.

What shocks many people even more than the fact that Aristarchos came up with the idea of heliocentrism in the third century BC is the fact that Aristarchos’s heliocentric model of the universe was almost totally rejected by ancient Greek and Roman scholars and never caught on in antiquity. Many people wonder why it was that the ancient Greeks never took Aristarchos seriously. In order to find out why Aristarchos’s heliocentric model of the universe was rejected, we are going to need to dive deep into the ancient sources.

“Archimedes’s Death Ray” Debunked

Most people with an interest in the history of science have heard the famous story of “Archimedes’s death ray.” In case you are unfamiliar with it, it goes like this: Supposedly, during the Siege of the Greek city of Syracuse by the Romans, lasting from spring of 213 BC through autumn of 212 BC, the brilliant Syracusan inventor and mathematician Archimedes (lived c. 287 – c. 212 BC) developed a spectacular invention to keep the Roman ships at bay; he built a death ray using mirrors to concentrate the light of the sun on the Roman ships, thereby setting them on fire. Unfortunately for all the people out there who love a good story about a brilliant inventor fending off enemy forces using science, the story of “Archimedes’s death ray” is certainly apocryphal.
