   Format: MarkdownItexNone of these pages (nth order set theory) list any references. Is this concept found in the literature?

   Format: MarkdownItexThanks for bumping up this issue. I don't really have spare cycles for this. But as a quick fix, I have deleted the previous Idea section (which didn't seem to make headway on explaining its subject matter) and added one reference: * [[Steve Awodey]], [[Carsten Butz]], [[Alex Simpson]], [[Thomas Streicher]], *Relating first-order set theories, toposes and categories of classes*, Annals of Pure and Applied Logic **165** 2 (2014) 428-502 &lbrack;[doi:10.1016/j.apal.2013.06.004](https://doi.org/10.1016/j.apal.2013.06.004)&rbrack; <a href="https://ncatlab.org/nlab/revision/diff/first-order+set+theory/2">diff</a>, <a href="https://ncatlab.org/nlab/revision/first-order+set+theory/2">v2</a>, <a href="https://ncatlab.org/nlab/show/first-order+set+theory">current</a>
