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.

Did King Porus Defeat Alexander the Great?

According to all surviving ancient historical sources, King Alexandros III of Makedonia (most commonly known in English as “Alexander the Great”) defeated King Porus (whose name is conjectured to have been Puru in his native tongue) of the Indian kingdom of Paurava in the Battle of the Hydaspes in May 326 BC.

Although Alexander was ultimately victorious, Porus and his men fought valiantly. The Battle of the Hydaspes was the closest one Alexander ever came to losing and he was reportedly so impressed by Porus’s valor that he asked him how he wished to be treated. Porus replied that he wished to be treated the way Alexander would have wanted Porus to have treated him. Alexander therefore appointed Porus as satrap of his own kingdom and the lands to the southeast as well.

Until I started writing answers on Quora, I had never heard anyone try to argue that Porus actually defeated Alexander in battle. We have nothing in our sources to suggest that and, as I shall explain in a moment, we have very good reason to doubt this assertion. Nonetheless, since I started writing answers on Quora around a year ago, I have discovered that there seems to be something of an obsession among Indian and Pakistani nationalists with “proving” that Alexander really lost and that the accepted narrative is a fabrication by the Greek historians who idolized Alexander.

In the answer, I intend to examine the historical evidence supporting the historical consensus that Alexander really did win the Battle of the Hydaspes. I doubt I will convince any hardcore Indian or Pakistani nationalists, but I am not writing this answer for them; I am writing it for those who are genuinely interested in knowing what really happened.

Spencer Ruins “Adam Ruins Everything”

Adam Ruins Everything is a comedy television series on TruTV starring comedian Adam Conover. It has been on air since September 2015 and has had, to date, three seasons, amounting to a total of sixty-five episodes. The basic premise of the show is that Adam Conover is an obnoxious know-it-all who cannot help ruining everyone around him’s favorite things by revealing to them the dark truths and common misconceptions surrounding them.

This premise provides a sort of framing narrative for a series of information-based comedy segments, which make up the bulk of each episode. Each episode usually consists of three segments debunking common misconceptions related to a particular topic, followed by a final “positive takeaway” segment in which Adam tries to make the audience feel better by putting a positive spin on everything he has said throughout the episode. Along the way, Adam cites various sources (some more reliable than others) and calls in people identified as experts to testify.

In general, most of the show’s main points are usually broadly correct. The show clearly really does strive for factual correctness, as demonstrated by their repeated warnings that the show is fallible and their multiple “corrections segments.” Sadly, they do not always live up to their aspirations. Often the errors on the show are errors of omission resulting from the fact that it is only a thirty-minute show and they try to cram no less than three different debunking sessions into each episode, which results in a series of extremely rushed information segments that end up leaving out a lot of really important information.

The Motivations behind Human Sacrifice

For people today, the fact that so many peoples throughout history have practiced human sacrifice seems absolutely baffling and horrifying. We tend to think of human sacrifice as the ultimate act of barbarism, an act that epitomizes everything savage and uncivilized about our species. Nonetheless, it is important for us to understand why people have historically engaged in this practice.

Human sacrifice has occurred in virtually every part of the world at some point in time and has occurred in some part of the world during every historical time period. Thus, whether we like it or not, understanding the motivations behind human sacrifice is a part of understanding what it means to be human.

Were Ancient People Conscious?

In 1976, the American psychologist Julian Jaynes (lived 1920 – 1997) published a controversial book titled The Origin of Consciousness in the Breakdown of the Bicameral Mind. In this book, Jaynes claimed that human beings were not conscious of their own thoughts until around 1000 BC and that stories about gods speaking to people originated from people hearing their own inner voices and mistaking them for the voices of external deities telling them what to do.

Jaynes’s claims were regarded as fringe, baseless, and bizarre even when he first proposed them back in the 1970s and today they are almost universally regarded by psychologists as the debunked relic of an earlier, less scientific stage in the development of modern psychology. Nonetheless, Jaynes’s hypothesis of the bicameral mind has garnered something of a cult following among non-scholars and has had considerable influence in popular culture, so I suppose it is worth writing a lengthy rebuttal to it.

What Did Ancient Greek Music Sound Like?

Nearly everyone loves music and the ancient Greeks loved music as much as anyone. Many of the poems that have survived to us from ancient Greece are actually song lyrics that were originally meant to be sung. Unfortunately, nearly all ancient Greek music has been irretrievably lost; no one alive will ever hear the original choruses of Aischylos, Sophokles, or Euripides sung with their original melodies.

Remarkably, though, a number of ancient Greek musical compositions have survived to the present day with musical notation, allowing us to reconstruct their original melodies—or at least something reasonably close to their original melodies. These few surviving compositions offer us a tiny window into a world of music that has been gone for well over a thousand years.

Did Abolitionism Exist in Ancient Greece and Rome?

The prevailing attitude towards slavery throughout the ancient Mediterranean world was essentially that being a slave was horrible and unpleasant, but that that was just the way things were and the way things always would be. As far as we can tell from the surviving sources, the idea that slavery even could be abolished does not seem to have occurred to most people.

There were apparently a few people in ancient Greece and Rome who thought that slavery was immoral, but these people seem to have been extremely rare, since they only appear briefly in the sources. Furthermore, we have absolutely no documentation of the existence of any large-scale, organized movement to abolish slavery in ancient Greece or Rome. Some people did criticize slavery extensively and there were probably people who wished slavery didn’t exist, but no one seems to have ever developed any realistic plans to abolish it.

Were There Any Female Rulers in Ancient Greece?

We are often accustomed to hearing how utterly oppressed women were in ancient Greece. To a large extent, it is true that the rights of women in ancient Greece were extremely restricted. Nonetheless, the picture we have of women in ancient Greece being totally excluded from any semblance of power is not completely accurate. Although female rulers were certainly very rare in ancient Greece compared to the number of male rulers, there were, in fact, surprisingly many of them overall.

Several of the ancient Greek female rulers on this list, such as Artemisia I and Artemisia II of Karia, are still relatively famous today. Many of the others on this list, such as Kratesipolis of Makedonia, are fairly obscure, but deserve more attention. For the main part of this list, I am confining myself strictly to Greek female rulers who ruled in their own names in Greece or western Asia Minor during the Classical and Hellenistic Periods, although there will be section at the end briefly listing some others who ruled outside of Greece. I am sure there are probably a few others that I have missed as well.

Was Aristotle an Objectivist?

Aristotle seems to get frequently brought up in conversation along with a certain twentieth-century Russian-American writer who has acquired something of a cult following among present-day Libertarians. You all of course know who I am talking about: Ayn Rand. The association between Rand and Aristotle is one Rand herself promoted—yet, as I will demonstrate, it is, for the most part, quite spurious. I think that, if Aristotle saw how egregiously Rand misconstrued his philosophy, he would not be pleased.

Ancient Greek Murder Mysteries

Murder mysteries are always a subject of popular fascination. From Sir Arthur Conan Doyle’s Sherlock Holmes stories to modern CSI television shows, everybody loves a good whodunit. Today, we are going to be looking at three famous murder trials from ancient Athens. We do not know the outcomes of any of these trials, which means that, from our perspective, you could classify these murders as technically “unsolved.”
