It is unclear what the actual topic of this page is intended to be, and why the content is significant in any way. Any important stuff could easily be moved to other pages on category theory. Jordan Mitchell Barrett (talk) 21:13, 26 February 2020 (UTC)[reply]

Strong Delete per WP:INDISCRIMINATE. --BonkHindrance (talk) 21:15, 26 February 2020 (UTC)[reply]

keep Another one for WP:MATHISHARD 8-(

This is a 2003 article, written to the typical sourcing standards of the time. The fact our standards have improved since is reason to improve it, not delete it. Andy Dingley (talk) 21:39, 26 February 2020 (UTC)[reply]

Even if it were sourced properly, the article still doesn't seem to substantively cover the idea of structure, let alone any other idea. It seems to be a "subjectless" article. Perhaps it could be saved by elaborating on its assertions (e.g. giving a rigorous definition of structure in a category, as is claimed to exist in the 3rd paragraph). --Jordan Mitchell Barrett (talk) 22:09, 26 February 2020 (UTC)[reply]

Merge with Mathematical structure. I’m not convinced that there is a need for a separate article; but the solution is a merger not deletion. —- Taku (talk) 23:12, 26 February 2020 (UTC)[reply]
Delete. A note: WP:INDISCRIMINATE is a completely invalid delete reason here. But what's here is beyond repair. This article is written like a personal reflection essay. At best, according to nLab, it seems to be a historical approach that Bourbaki was developing as an alternative to the category theory of today, but it didn't catch on. As such, it doesn't seem to be notable. If this is merged anywhere, it should be to Category theory, but I would still recommend deleting – there's nothing here of sufficient quality to merge. –Deacon Vorbis (carbon • videos) 00:56, 27 February 2020 (UTC)[reply]
Redirect to concrete category, where the concept is discussed in some detail. Insofar as structure in the categorical sense is associated with a pair of categories and a faithful functor, this concept is fairly well described in the concrete category article. I don't think anything needs to be merged, as the target article has better examples and the more general concept is covered in the Concrete_category#Relative_concreteness section. --{{u|Mark viking}} {Talk} 03:45, 27 February 2020 (UTC)[reply]
Redirect to Category theory#Categories, objects, and morphisms (not convinced about the target though), nothing in the article worth saving, but the title is a reasonable search target. It's not clear to me what the redirect target should be. I'm not sure that Concrete category is the right place, since it's about a particular type of structure. Similarly, Mathematical structure is focused on structures imposed on sets. At first I was going to suggest Abstract structure, but that article has basically the same problems as this one! For now, Category theory#Categories, objects, and morphisms is of the right generality but is perhaps missing some details. — MarkH₂₁^talk 04:00, 27 February 2020 (UTC)[reply]
