> There are plenty of “unreasonable men” adapting the world to themselves.

You say that like it's a counterexample, but is that not literally what the quote is saying? I mean what's the difference between that and:

> the unreasonable [man] persists in trying to adapt the world to himself.

I think Wikipedia does a good job of defining what most people understand by “progress”.

https://en.wikipedia.org/wiki/Progress

> Progress is movement towards a perceived refined, improved, or otherwise desired state.

I.e. progress is understood as positive advancement. Otherwise we use other words like “regression”.

The quote as it is typically used is advocating for the unreasonable man because they precipitate progress. My point is that we shouldn’t idolise this idea of advancement in the abstract, because pretty clearly it can turn everything to shit. We’re not benefiting from those unreasonable men, quite the contrary.

I think the use of "progress" in the quote is somewhat ironic -- "movement towards a perceived refined [...] state", as the definition puts it; an unreasonable person's perception of progress likely doesn't match up with a reasonable person's.

As I see it, the quote neither advocates nor critiques unreasonableness, but rather observes that unreasonable people are most often the ones responsible for change. Whether you take that as a lesson on the merits of unreasonableness, the dangers of it, or something in between, is up to interpretation, and depends on how much one values reasonableness vs progress (for the record, I've heard the quote more often in a negative sense by people who put reasonableness above "progress"). It also depends on one's definition of "reasonableness" of course, and whether something can be unreasonable yet still a positive.

So I guess my point is that the quote can mean just about whatever you want it to mean. It's an interesting litmus test. I do agree that people using it as carte blanche for unreasonableness in the name of some sort of nebulous "progress" is, well, unreasonable, though with context I'm certain GP was using it as more of a critique.
