Re: Not invariant but good

Hi - Thanks for posting. I tried to give a formal definition of "evil for structures" in January,

but nobody challenged it, endorsed it, or had much of an opinion.

I remember liking it, but I don't remember what it was! I can look it up...

In the end, the terminology might be doomed, not because it is offensive, but because people can't agree on any one meaning.

Or it could be like "natural" - it has a technical meaning, but it also has a penumbra of nontechnical meanings that are very important in mathematics. Best, jb
