“Man is the measure of all things” … or is he?



“It is indeed the opinion of Protagoras, who has another way of expressing it. Man, he says, is the measure of all things, of the existence of things that are, and of the non-existence of things that are not.”

– Socrates, as recorded in Plato’s “Theaetetus”

Is all truth in the “eye of the beholder?” Protagoras thought so, but Socrates didn’t …

Socrates and Plato both reported some words from the Greek sophist Protagoras, in Plato’s dialogue “Theaetetus.” The dialogue features a character by the name of “Socrates,” believed here to represent the actual and historical Socrates. The character of “Socrates” thus quotes Protagoras as saying that “Man is the measure of all things.” Thus, we seem to have the word of both Plato and Socrates that Protagoras really said this. But what does it mean that “Man is the measure of all things”? As Socrates correctly argues, it seems to mean that all truth is in the “eye of the beholder” – or, at least, that Protagoras believed this to be the case. “If I believe that something is true,” say some today, “then it must be true.” But this belief leads to a number of problematic conclusions, as Socrates proceeds to point out in this same dialogue, the “Theaetetus” – named after one of the other characters in the dialogue. Nonetheless, some today (notably certain postmodernists) still proclaim that all truth is in the “eye of the beholder.” It is acknowledged that some things really do work this way, but it would seem that other things do not. Thus, this dialogue is a timeless meditation on objective truth whose arguments need to be heard today. Thus, it may be worth examining here in this post.

A review of “Aristotle” (audiobook)



“We must not expect of Aristotle such literary brilliance as floods the pages of the dramatist-philosopher Plato. Instead of giving us great literature, in which philosophy is embodied (and obscured) in myth and imagery, Aristotle gives us science, technical, abstract, concentrated; if we go to him for entertainment we shall sue for the return of our money.”


Aristotle is one of the most influential philosophers in all of world history. More than 2,000 years after his death, his name is still known, and his works are still studied. I knew his name early in my childhood, but did not examine his ideas until early college. My first philosophy class introduced me to Aristotle, and made me want to learn a bit more about him. As it turned out, my dad already had this audiobook about him by this time. Thus, the two of us listened to it on a moderately long road trip. My dad had already listened to it, but I had not – although I had listened to a similar audiobook about Plato by the same company (Knowledge Products). I greatly enjoyed this audiobook (my second from this series), and it helps that Charlton Heston is narrating it. Nonetheless, this audiobook makes one’s brain hurt after a while.

A few problems with Plato’s “Republic” (and his ideal state)



“You know also that the beginning is the most important part of any work, especially in the case of a young and tender thing; for that is the time at which the character is being formed and the desired impression is more readily taken.”

Plato’s “Republic” (written around 375 BC), Book II – spoken through the character of “Socrates,” whose depiction in “The Republic” probably does not represent the actual views of the historical Socrates (although his depiction in some other Plato dialogues may really do so)

I recently finished reading Plato’s “Republic” in the original Greek

My first encounter with the ideas of Plato was in an intro to philosophy class in 2005. I became particularly interested in his work “The Republic,” and later read the work in English translation during the winter of 2006-2007. At that time, it was for my own amusement, and I read it all the way through in English. Later, the book was assigned for an intro to ethics class in 2009 (which was also a philosophy class). But this time, it was for an accelerated summer class, so I was forced to limit myself to just the assigned parts of it. I figured that if I had read the work all the way through long before this, then I didn’t need to read the entire work this time around. Later on, I learned the Ancient Greek language. Thus, I was brave enough to want to tackle the entirety of “The Republic” in the original. Now, I have finally finished doing so – a task that took me roughly four years. (Specifically, I read it from February 2019 through February 2023.)
