Dear All, I am displeased with the idea that terminology is purely conventional and that everything is acceptable. The "evil" terminology is promoted by a small group of peoples active in the nLab. It does not reflect a commun usage in the mathematical community. Best, André -------- Message d'origine-------- De: Ruadhai [mailto:ruadhai@gmail.com] Date: ven. 24/09/2010 20:38 À: Eduardo J. Dubuc Cc: Categories list Objet : Re: categories: subculture Dear all, I'd just like to point out that a quick google search of "category theory evil" gives the correct definition, from the nLab page. As long as articles are referenced properly, this is a non-issue. Moreover, frequently people define things in papers which remain unused outside that one article - as long as everything is clear, there is no problem here. With regards the original problem, that evil is a poor choice, I personally see little point in changing a word no one would be offended by.
