Yes. exempli gratia a method returns data related to the class. What better way than via a class. What better place to declare the returned class than embedded.

Yes, if appropriate. The maxim "the right tool for the job" applies.
I manage visibility with private/protected as necessary if the embedded class is only used internally by the surrounding class. An example would be elements in a data structure used within the surrounding class.
If an embedded class is public, then it is embedded because it has relevance only in relation to the surrounding class. The example here would be the embedded class contains properties and state of interest to users of the surrounding class and it's either cumbersome or infeasible to have the surrounding class supply those values itself.

I mostly do C# these days. But I find that when I am designing a dialog box for a program, I usually need more than a single primitive value returned. What I seem to end up doing is writing an embedded class to handle all the returning data. I make it an embedded class because I can keep it associated with that dialog box. Using a class gives it an instance that doesn't vanish the moment the dialog closes. There have been a few occasions when I've decided that an embedded class was a good solution as a class to handle multiple issues in a project. When I get to that point, I usually elect to change the class from embedded to a separate file.

Statement 1: Every rule has an exception.
Statement 2: Statement 1 is a rule. Therefore Statement 1 has an exception.
Conclusion: There is at least one rule which has no exception.
Would you agree with this conclusion? If so, is there any example of a rule having no exception?

Kurt Gödel proved a version of Statement 1:
In any formal language, there are questions that can be asked but not answered.
A perfect example of Gödel's incompleteness law can be found in math:
- Positive Integers (lengths) can subtract a larger number from a smaller number. The answer is a negative integer, leading to:
- All integers can divide and result in a fraction, leading to:
- Fractions can be used in geometry to result in real numbers, leading to:
- Real Numbers can have square roots that are imaginary, leading to:
- Complex numbers, etc...

A rule having no exception: "death and taxes"

I once discussed that with my religious brother-in-law. He insisted that there are exceptions to that rule. May not to the "taxes" part, though.

Agreeing that a proof is valid is not the same as stating that it must be true. Now claiming that it is true could suggest that one should provide the example. Or provide other discussions that would suggest it is true. Or just believe and dispense with the work.
My favorite example with this is geometry (Euclidean) where parallel lines do not intersect. I certainly believe it. And I doubt anyone can provide an example that shows they do intersect. But for that matter they cannot provide an example where they do not intersect either.

Though I am not a theoretical physicist, have heard that "space is curved", whatever it means. If space is curved, will there be a possibility of parallel lines meeting? Not sure.

Spherical geometry rather than Euclidian.
But one can also start in on a definition since a line, even theoretical, could still be claimed to be something that must exist in the universe. So if the universe is curved then the line must be as well.
But then what happens with the degrees in a right triangle which can only exist if those lines do not intersect.

You :
does a solution to the Russel Paradox exist
ChatGPT
Yes, several solutions to the Russell Paradox exist, which emerged after Bertrand Russell presented the paradox in 1901. One common solution is to restrict the comprehension principle, which states that for any property, there exists a set of all objects that have that property. By restricting this principle, mathematicians and logicians have been able to formulate set theories, like Zermelo-Fraenkel set theory (ZF) or von Neumann-Bernays-Gödel set theory (NBG), which avoid the paradox by disallowing the formation of certain "self-referential" sets. Another approach is to distinguish between sets and classes, where classes can contain sets but not be sets themselves, thereby sidestepping the contradiction. These solutions have allowed set theory to develop into a foundational framework for mathematics without succumbing to paradoxes like Russell's.
Me : If Statement 2 is a rule it must have an exception.
Conclusions: Statement 1 has no exception. There is at least one rule which has no exception.
