Parmenides and the moon


 There is a new book out about the Greek philosopher Parmenides, the central figure of the Eleatic school. Well, it is listed as a 2025 publication.  I, for one, will call that "new" given the antiquity of the subject matter. 

It is an anthology titled simply, Parmenides: New Perspectives, edited by A.G. Long and Barbara M. Sattler.

The Eleatics may have made their greatest impact on subsequent philosophy through Parmenides' disciple Zeno. The simplistic view (my view) is that Parmenides took a position that seemed, simply, nuts. There is no change, no motion, and no division in the word, there is only Being.    

Zeno provided arguments for that position that made it seem less nutso, by making the common sensical world of change, gaps, and differences itself seem oddly paradoxical.

That conventional understanding makes Zeno seem the more interesting figure in that dyad. 

But the Long/Sattler book offers "new perspectives". One of them is that Parmenides was also an astronomer. He appears to have been the first to discuss the moon NOT as a source of light in itself but as an inert mass that reflects light from the Sun.  Apparently no less of a figure in the history of philosophy than Karl Popper saw this as a major Parmenidean contribution.

What does that have to do with his monism?  Little, directly, but when someone says something wacko it helps to know that he has also done some keen analysis at some point.  Otherwise one wonders: why is the wacko even worth putting into history books?

Searle: The Chinese Room

John Searle has become the object of accusations of improper conduct. These accusations even have some people in the world of academic philosophy saying that instructors in that world should try to avoid teaching Searle's views. That is an odd contention, and has given rise to heated exchanges in certain corners of the blogosphere.  At Leiter Reports, I encountered a comment from someone describing himself as "grad student drop out." GSDO said: " This is a side question (and not at all an attempt to answer the question BL posed): How important is John Searle's work? Are people still working on speech act theory or is that just another dead end in the history of 20th century philosophy? My impression is that his reputation is somewhat inflated from all of his speaking engagements and NYRoB reviews. The Chinese room argument is a classic, but is there much more to his work than that?" I took it upon myself to answer that on LR. But here I'll tak...

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.   We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a maj...

Five Lessons from the Allegory of the Cave

  Please correct me if there are others. But it seems to be there are five lessons the reader is meant to draw from the story about the cave.   First, Plato  is working to devalue what we would call empiricism. He is saying that keeping track of the shadows on the cave wall, trying to make sense of what you see there, will NOT get you to wisdom. Second, Plato is contending that reality comes in levels. The shadows on the wall are illusions. The solid objects being passed around behind my back are more real than their shadows are. BUT … the world outside the the cave is more real than that — and the sun by which that world is illuminated is the top of the hierarchy. So there isn’t a binary choice of real/unreal. There are levels. Third, he equates realness with knowability.  I  only have opinions about the shadows. Could I turn around, I could have at least the glimmerings of knowledge. Could I get outside the cave, I would really Know. Fourth, the parable a...
