I completely agree with you that human knowledge, whether individual or collective, is severely limited compared to all there is to know in the Universe. Part of this has to do with the fact that we as a species has only been observing the Universe scientifically for ~500 years. But it probably also has to do with the physiological limitations of homo sapiens. I don't disagree with any of that.

But what does that have to do with the sentences you quoted from me? Is it even relevant? Human knowledge is limited, so what?

    1. Human knowledge is limited.
    2. ???
    3. Ergo, progress is an illusory concept.

You haven't supplied a single proposition that could fill the space of #2.

Meanwhile, the fact that our mental capacities are limited has not prevented us from "rising above certain petty disputes arising out of ... ego, vanity, and self-preservation" at least from time to time, even if it's only .0001% of the time. The idea that progress always happens is a ridiculous proposition, but the idea that progress is always stunted by other factors is just as laughable. Also, even if we did agree that progress never happens in reality, there is still a very large logical gap between that and the (even more preposterous) proposition that the concept of progress itself is an illusion.

If you say "True progress rarely if ever happens", fine, we can talk about that.

If you say "Your definition of progress is wrong", fine, we can talk about that.

If you say "Progress is not one thing but many different things depending on the context", fine, we can talk about that. Cultural relativism is nothing new, there's plenty of good philosophy on that topic, and you're at least a century late to the game if you think waving the flag of cultural relativism will change anything.

But if you say "The concept of progress is an illusion" (or some variation of it), that's just one of those strings of profound-looking words that college freshmen put down in their PHIL 101 essays. If there is any useful content in such catchphrases, I have yet to see any. So I suppose it's just a figure of speech.

> Your argument has the appearance of something that's badly contrived (or derived).

Arguments don't have the "appearance" of being badly contrived, and even if they do in some sense, it doesn't matter. Either they are badly contrived, or they are not. If they are indeed badly contrived, it should be possible to say why without committing the fallacy of ignoratio elenchi.

"The arc of human progress - as defined by the narrow parameters of decreasing number of recorded human conflicts and genocides, declining number of incurable devastating medical conditions, improving/degenerating overall environmental health of the planet etc - is an illusory one."

1. Knowledge is an absolute necessary element for the overcoming of "cultural backwardness, blindness and folly" and to advance "to ever more elevated stages of enlightenment and civilization" and thereby the progress of humans. 2. Human knowledge is said to be limited. 3. Ergo, human progress will always be stunted by the said natural limit of knowledge. 4. Further: There is no necessary condition that prevents humans from reverting to the ways of the past once that limit has been reached.

1. Agreed. 2. Agreed. 3. Nope. Human progress will be limited by the aforementioned limit of human knowledge, but this is a very large limit, so there's plenty of room for progress before we hit the limit. We might have already hit the limit in some areas, but that doesn't mean we won't keep making progress in other areas. 4. Agreed, but there is no necessary condition that says that humans MUST revert to an inferior state, either. Maybe they'll just stagnate until evolution produces a superior species with higher limits of knowledge. Why not? Just because X isn't necessary doesn't mean that not-X is necessary. Usually, they're both unnecessary.
