Definition talk:Class (Class Theory)/Zermelo-Fraenkel

This might turn out to be a much bigger problem than I had initially anticipated. There are lots of pages that use proper classes, and unless there's a way to allow proper classes into ZFC (which I don't think there is), all of those pages may have to be reworked, or get tagged with. --HumblePi (talk) 20:03, 26 April 2017 (EDT)


 * The enormity of the task that you see ahead is one big reason why nobody has got round to attempting it yet.


 * For now, attach your tag to everything you see as needs it -- I have made it so that all such pages get included in the new Category:Class Theory Work in Progress.


 * This should then allow us to see the prospect before us. --prime mover (talk) 04:25, 27 April 2017 (EDT)


 * Okay, I'll do that then. Once I've finished tagging all of those pages we can figure out what should be done with them. --HumblePi (talk) 18:18, 27 April 2017 (EDT)


 * Also bear in mind that the treatment as provided by the contributor who posted up the contents of the Takeuti and Zaring book was called into question for its lack of cohesion and imprecision. I can't comment on that because I was not in the position to be able to comment adequately on it (it's out of my area of expertise). So when all this is done, tread carefully where those pages are concerned. --prime mover (talk) 18:58, 27 April 2017 (EDT)
