Propositions are philosophically vexing.

The term ‘proposition’ has a broad use in contemporary philosophy. It is used to refer to some or all of the following: the primary bearers of truth-value, the objects of belief and other “propositional attitudes” (i.e., what is believed, doubted, etc.[1]), the referents of that-clauses, and the meanings of sentences.

One might wonder whether a single class of entities can play all these roles. If David Lewis (1986, p. 54) is right in saying that “the conception we associate with the word ‘proposition’ may be something of a jumble of conflicting desiderata,” then it will be impossible to capture our conception in a consistent definition.

Philosophers have a notion, a feeling about it. Still, propositions are not mere philosophical esoterica. A proposition is what you said. Legally. Scientifically. Morally. Factually. Propositions are communication. Or maybe it's the other way around?

Whatever. They are the reason ML is cool and neat and exciting to me while LLMs make my philosophical skin crawl.

It's talking to a plastic bag caught in a bush and thinking it's God.

Non-philosophers may be confused about the above:

My skin crawls not because LLMs are yucky but because LLMs literally don't say anything.

You only hallucinate that they're saying things.

But most people lack the insight to notice this. So I post.

But it's hard to explain how little LLMs do when people feel certain they are doing everything.

@CptSuperlative I've said right from the time they announced ChatGPT that humans hallucinate far more than AIs. 100% more.
