On the Claim that Properties are Sets
David Lewis, in his 1986 book On the Plurality of Worlds, argues that properties are sets. Any property should be taken as “the set of all its instances — all of them, this- and other-worldly alike. Thus the property of being a donkey comes out as the set of all donkeys, the donkeys of other…

On the end of analytic philosophy
In his blog post ‘The End of Analytic Philosophy’, Liam Bright paints a starkly pessimistic — almost Spenglerian — view of the current state of what we still call analytic philosophy. I choose that last phrase with care. Once there may have been a coherent conception of philosophy as the discipline whose task it is…

The 50 book challenge
In 2019, I read 27 books. But I wanted to read more. I wanted to find a way to motivate myself to pick up a book in the evening, rather than spend time on my phone, or the internet, or playing a computer game, or doing who knows what. I love reading books. But it’s…

This almost entirely excludes the notion of a mathematical proof, to the point that there are highly educated people who have never even heard of the concept.…

Peano and the natural numbers

(I don’t think there’s anything original in here; it’s just me thinking through the topic.) What are the natural numbers? Of course, they’re 0, 1,…

Trump’s Failure
For months, Donald Trump has laid the groundwork for his post-election strategy: refuse to concede, start legal challenges, undermine the legitimacy of the democratic process and of Biden’s victory. And yet, this strategy continues to surprise me. And it should surprise you too, for it makes little sense. How is it possible that at this…

Two sonnets on rocks
I wrote two sonnets today. First, one about rocks. Then, another one about rocks, but now starting from (a variant on) the line “He cracked her open to her very core.” Sonnet. On the Topic of Rocks O rocks, o little rocks, you small parts of the EarthO rough detachèd flakes from off our Mother’s…

W. F. Hermans (2011)
Die liefde heet ik geen manie die ieder voelt voor zijn genie ik lees zijn boeken vol emotie en kniel dan neder in devotie voor W. F. Hermans, kloeke held die ons de Waarheid heeft verteld die in de kern der wereld zag en niets vond dan wat hoongelach. Mijn hart versnelt als ik hem…
