That sounds suspiciously like something a taboo would say that has something to fear from being looked at. ;)
I think this chain of reasoning is made of links that do not self-evidently follow. From my lay perspective, taboos seem more complex, resilient and variable to require a perfectly dogmatic approach to hold up. If they were this easy to bring down, they'd all be gone.
I'm also not sure what a "culture without taboos" is, or one has ever existed. Also, what is meant by "peak"? Is there an optimal amount or set of taboos? How do cultures with taboo-ical differences (and their peaks) compare to each other across space and time?
I think it is good and healthy to approach taboos with curiosity, whether it is to interrogate them or to appreciate them more.
Nothing there about causing cultural decline, just evidence of it, and thereby limits on the kind of culture that can host the attitude you describe.
This appears to be an entirely impractical definition, to the point that it would not allow a taboo to ever exist in a group of people capable of any sort of rational discussion. Any two moderately curious and independently-minded people could simply destroy any taboo by talking about it. They could even do it on purpose, using this fatal weakness.
Taboos, as in: the actual attitudes and behaviors of people, do not simply disappear the moment they are named or even questioned. I think we have to allow for taboos to be more nuanced, or we will struggle to describe the actual, interesting phenomenon, let alone do anything useful with it.
> once a culture has no taboos it has no real vitality or potential for growth left
That's an extraordinary claim on multiple levels, even when allowing for different ideas of what taboos are and how they work. I already mentioned some questions this raises, which makes it surprising to find the naked claim simply restated, in an even stronger form.
It's the kind of sentence that can sound really deep and powerful in passing, but when you look at it, is really only a huge, gaping question mark in a fancy dress.
I'm also not going to guess what point you're trying to make. I'd ask you to explain how exactly you think Overton windows relate to our argument about taboos, because, despite a superficial similarity, taboos and Overton windows deal with different things and are very much not the same; but I'm not interested in this style of discussion, sorry. Have a nice day!
There's a taboo to marrying your blood sibling, but discussing such marriages is fine. If a culture generally allowed marrying such a sibling I think it'd be past its peak, maybe. But I don't see how discussing it would contribute to that.
You're right that taboos also concern actions, not just discussion, but in this case it's probably both.
Sure, but the point is that they should just say that, and the person who raised the issue must then explain why it's worth their time. Maybe there's an important point they're trying to make, maybe not.
To me taboos is just society taking shortcuts. This is fine, but lets admit that we are taking shortcuts.
And if the relationship goes bad you lose a family member, not just a lover.
Is it always wrong? To me, unquestionably no (consider my example.) Is it risky? Yes.
That sound like yet another assertion that some people are so fond of and that I personally find totally baseless and irrelevant. You are simply proclaiming that a thing you like is good because it is good. So what? I don't like it and I want it gone. And I don't care that you think it is good unless you can come with some argument I can understand from my own set of values.
