    At dichotomy between nice objects and nice categories I added a quote from Deligne about allowing awful schemes gave a nice category of schemes. I can’t find the page I was thinking of where this dichotomy is also mentioned along with attribution of the general idea to Grothendieck. I wanted to add it there as well.

    Could a word of explanation be added to section 3? How does Isbell self-duality help there?

    Re #1, was it the discussion at the bottom of nice topological space?

    I created a page about the collection Matériaux pour l’histoire des mathématiques au XXe siècle containing the Deligne’s article mentioned above.
