I'm Charles Stewart, a copy-editor and logician based in Berlin, who is specifically interested  in proof theory, modal logic, applications of logic to computer science, philosophical logic, and mathematical structures for semantics, and increasingly, history of logic.

I've been less active since November 2022 when I was treated for brain cancer. While the cancer is gone, the effects of the life-saving surgery will take a long time to fix. My editing speed, while improving, is much lower than before.

I was quite active in both the article deletion process, participating in XfDs and [[Wikipedia:Deletion review|deletion reviews]], and the [[Wikipedia:WikiProject Articles for creation|article creation process]] where I was a reviewer of AfC drafts. Since hospitalisation, I have not been active in either process.

I'm a participant in the excellent Wikiproject for mathematics, the [[Wikipedia:WikiProject Mathematics]]. I'm also a participant in the rather less successful [[Wikipedia:WikiProject Philosophy]], and a cofounder of the near-defunct [[Wikipedia:WikiProject Logic]]. 

I have a sort of to-do list on [[User:Chalst/tasks]].

=== Logic ===
Most of my editing activity has been to do with logic, and an idea of what I count to be logic can be found at [[User:Chalst/logic-watchlist]].

<!-- DELETED
A goal in this area is to help the main article on the road to featured status. 
-->
=== Mathematics ===
I've edited many mathematics pages, but I'm most interested in linear algebra and category theory.

=== Mindfulness ===
I'm interested in improved states of consciousness. While I am not a Buddhist, I think that the Buddhist analysis of the mind has been very fruitful and the concept of [[mindfulness]] is crucial to this analysis.

I've edited several pages on Buddhist philosophy and applications of mindfulness.

=== Creating and deleting pages ===
I'm intermittently active at AfD and DRV.  I used to be involved with AfC, but do not edit often enough since my cancer treatment (cf. [https://xtools.wmflabs.org/topedits/en.wikipedia.org/Chalst/118 my edits currently in draftspace]).

=== Resources ===
I started to put together an annotated bibliography which someday might be of use to other editors in these areas at [[User:Chalst/bib]].

I have a list of [[User:Chalst/drafts|userfied drafts]].

==Attitude to policy and practice==
{{Centralized discussion}}
There are two main activities that editors must carry out well to best support Wikipedia: content creation and quality control (or maintenance). In the early days enthusiasm and lax policy outstripped the ability of the maintainers to toilet train the encyclopedia and so guidelines and the power of maintainers had to grow.  The success of the encyclopedia attracted problematic editors, those who had strong "tribal" biases and those with conflicts of interest serving SEO efforts.  The guidelines have evolved to meet the needs of maintainers of articles in these "battlefield" domains, but outside those areas, the legalism of those policies have a chilling effect on content creation; the Wikipedia enterprise needs to better nurture content creation if its content coverage is to grow and it is not to keep losing content creators. 
===Expert editors===
:''Relevant pages: [[Wikipedia:Perennial proposals#Only allow the truth in articles]], [[Wikipedia:Common knowledge]]''
I think the encyclopedia, for a mix of historical and policy enforcement reasons, effectively undervalues expert contributions to its great detriment.  Quite a few editors are too suspicious of how experts make assertions in passing that non-experts regard as nonobvious. From the expert point of view such steps may be intuitive, regarded as common knowledge ("So-and-so and so-and-so said as much at this recent conference")  and too obvious to be worthy of publication.  But when such contributions are challenged by the overly skeptical, current practice effectively favours ignorance and devalues expertise.  

'''Recommendation''': Application of the core policy of verifiability should recognise that when experts who lack conflicts of interest maintain that claims are obvious to experts, then some justification of the claim has been made.  Common law deriving from the British tradition is the evolving consensus governing the interpretation of law, it recognises "obvious to experts" as a class of evidence, and it has rules for its applicability. Wikipedia should have the same.

It is fair to insist that the expert editor ensures the claim is made in clear and accessible language, and the editor should be able to name another expert who they have confidence will agree with them. It is fair also to disregard claims to obviousness above the level of the casually interested amateur on "battlefield" topics. But I would like the implementation of verifiability policy to accept some tag indicating the desirability of finding a source (perhaps <nowiki>{{source sought}}</nowiki>) as adequate with claims asserted as obvious by experts.

I've generally not had problems making my own contributions within my domains of expertise - "obvious to experts" has sort of been the rule in many of the areas I have created most content - but I have seen other experts suffer from this excessive skepticism and become demoralised.

===Source reliability and deletion practice===
Encyclopedia maintenance requires both scrutiny of sources to ensure they adequately justify content and a deletion policy that keeps standards high by excluding articles that contain no valuable content and are likely to be a maintenance problem in the future.  However, the use of venue as a proxy for quality of sourcing both greenlights problematic content and excludes worthwhile material out of hand. Likewise, the criteria for notability is often not a good proxy for the actual interest of the topic. Outside of excluding original research and entirely promotional material, Wikipedia's deletion process is, in my opinion, far too deletionist.  

'''Recommendation''': We should regard a source for a claim as reliable if it refutes reasonable doubt about the claim.  Bias in sources can be handled by good NPOV authoring practice, and venue only suggests what kind of review claims have had, it does not eliminate the need for editors to evaluate the material.

'''Recommendation''': Articles should be regarded as notable based on an assessment of general interest in the topic.  

I'd like to see the idea that venues can accumulate notability through bringing several notable works to the public; this view is unpopular, cf. discussion at https://en.wikipedia.org/wiki/Wikipedia_talk:Notability/Archive_67#Cumulative_venue_notability

===Editor support===
On a positive note, Wikipedia provides excellent facilities to support not just maintenance but also content creation.  I particularly appreciate the [https://wikipedialibrary.wmflabs.org/ Wikipedia Library Card Platform]. <ref>Recommendation: we should thank the [[WP:LIBRARY]] team.</ref>
