I noticed for one sub, there is an "About" tab, and a "Menu" tab on mobile. But another sub, the Menu tab doesn't appear. Both have wikis with subpages. What is the explanation?

Your sole moderator is also the moderator of r/leftist which he is currently actively destroying. The sub of 50k members is being held hostage by a mod with his own agenda. Good luck.

It's not a casual question. Apparently, there is an article in the *Atlantic* with different views on it. It's the new 'what color is this dress?' question.

I'm no mathematician so maybe I misunderstand but it seems to me like something in zfc might be arbitrary. I think I understand the concept of a set, where the quantity of 5 is a set of 5 thus numbers are sets. However, let's take the idea of an empty set.

Now my understanding of what an empty set is, is a box of chocolates w/o any chocolate. It's purely a mental overlay of reality when we say the box is an empty set. But the question is does nature deal in empty sets outside of the one's invented by our minds?

It seems to me that if mathematics may be said to exist in some capacity, such as if math is merely the laws or rules of existence, that it would not be meaningful to have an "empty set". As that's saying there is something ontologically more to a set than it being the collection of things in a set. In one instance your saying a set is a thing in and of itself, in the other "set" just refers to the things collectively considered such that an absence of the things leaves you with no set rather than something that's empty.

This "something" that is called a "set" such that it can even be empty seems like something that has no ontological reality and things that have no ontological reality can't be said to exist.

I guess the question is if mathematics exists mind independently can an empty set actually exist also or is it merely invention and if so how can the concept be said to be a "foundation" of math? Thoughts?

If there is something we should thinking about, talking about, or doing something about please bring it up here.
