Thanks for the link, though the exact nature of the inquiry into Galileo was not my point. It was accepted _as truth_ that the sun went around Earth by a great many people back then.
Going back up the chain in this thread, pesmhey said:
> Gender and sexuality and identity and really all of reality is fluid.
To which you replied:
> Truth is Truth. Reality is not fluid, our existence is very real, and so are the laws of reality just as real as the laws of physics.
I can't speak to what pesmhey intended with "all of reality is fluid", and I don't agree with that as phrased… What we perceive as reality is limited by our understanding of it. If you look up and watch the sun travel across the sky, it's easy to think that the sun goes around the Earth, just as the moon does.
It would be folly to say that humanity collectively hasn't learned a ton about human biology over the past 100 years. When it comes to gender, sexuality, and identity, we're continuing to learn and what may be seen as "truth" today may prove to be not quite right with more knowledge.
Just this week, in fact, there was the news about Caster Semenya and how the olympic folks think her testosterone levels are too high for her to compete as a woman[1]. 100 years ago, they couldn't have tested for that (testosterone was apparently discovered around 1890[2], so I don't think they would have had tests for levels of the hormone then).
To be clear, I'm not trying to make a point about the Catholic Church, but rather about truth and reality. The Catholic Church can move forward with time. I wish more people in this country would get on board with Laudato si[3] and see "climate as a common good" that we need to take seriously. (Of course, most people in the US are already on board with respect to the need to address climate issues, but those holdouts are a problem.)
FWIW, I acknowledge that progress is not always forward and that there are, indeed, aspects to our current time that will prove to be objectively problematic when we look back at them from some time in the future (just as there always have been). I don't know how common it is in actual practice, but I think stifling contentious discourse at universities is likely to be harmful for the advancement of knowledge over time.
Anyhow, this has become a ramble, and it wasn't really my intention to write an essay. Given that, I'll just stop rather than write a proper conclusion. Sorry :)
