I think it is a conclusion because the author summed the entire world in a paragraph. He brought in god and how he created the world and how he was lonely. This concludes no matter what you have you will be lonely if you don't have someone to share things with. Hoffmann is a practical author and does not like boring things. That's why he gives random examples like example of a coffee cup he has given in his conclusion para 190. Also another reason that makes me believe this is conclusion because he started the paragraph saying "we look like to give our readers a gift before they move on to other books" it shows how he's starting to say his goodbye and then he ended his book talking about god because god knows everything and everyone.
