alt Hacker NewsI don't understand the downvote, it's like "nooo, their ideas were exactly as good as the ones we have today, humans don't learn over time, how dare you imply we used to be stupider, it's sacrilege".
So I object to this weird article of faith every time it comes up, we can't have been exactly as sensible and exactly as clever in the past as we are today, it doesn't make any sense to say that. But it's somehow become right-on to say that it's so, as if denying it is a prejudice like timeism or something. It obviously matters to some world view, equality maybe?

I didn't downvote you.
But, I'm not saying that humans haven't learned anything, but that cognitively we haven't changed. A roman citizen has the exact same brain capacity to reason and adapt as we do today. There is zero separation from ancient human vs. modern human in that aspect.
You are conflating collective knowledge with individual human intelligence. That roman looking at bird entrails to predict the future was using the exact same pattern-recognition ability we use today to look at data visualizations, or trend graphs.
You could go back in time, steal an ancient roman baby, and raise them in today's year and they would be no different from you or I.
We have access to different data points today. But the way I read the original post is that human mind as such did not meaningful change. If you took a Roman or Egyptian embryo from 5k years ago and incubated it today, you'd have a modern human. The fact that many people back then had crazy ideas, is orthogonal to the biological argument at hand - and that's before we look at amount of people with crazy ideas today, many of which are largely the same.
Basically I think we have to pick a lane on whether we are talking biology, vs culture, vs knowledge and accumulated data.
