Remember that when adding content about health, please only use high-quality reliable sources as references. We typically use review articles, major textbooks and position statements of national or international organizations. WP:MEDHOW walks you through editing step by step. A list of resources to help edit health content can be found here. The edit box has a built-in citation tool to easily format references based on the PMID or ISBN. We also provide style advice about the structure and content of medicine-related encyclopedia articles. The welcome page is another good place to learn about editing the encyclopedia. If you have any questions, please feel free to drop me a note. Doc James (talk · contribs · email) 02:59, 18 August 2016 (UTC)

Your addition of commentary to the page in Zorn's lemma
[edit]First, claims that a statement in the page is incorrect should go to the talk page for discussion, not to the page itself. Second, you are incorrect in your understanding of the paragraph in question. You wrote:
This Section contains a fallacy. If P is empty then no chain can have an upper bound in P (just because P is empty). In particular, the statement "However, the empty set is a chain (trivially), hence is required to have an upper bound, thus exhibiting at least one element of P." is a fallacious inference. Thus the premise of Zorn's Lemma is not satisfied, contrary to what this Section implies, and the conclusion that P has a maximal element does not follow.
What the section is saying is that if P satisfies the hypothesis of Zorn's Lemma, then it cannot be empty (since the empty chain must have an upper bound in P, and so P must have an element). This is logically equivalent to saying that the empty set does not satisfy the hypothesis of Zorn's Lemma, which is what you are saying. So you are incorrect in claiming that the Section implies that the empty set satisfies Zorn's Lemma. The section makes no such claim, it is making the claim whose contrapositive you are arguing for. In short, you are arguing for what the page says. Magidin (talk) 17:04, 23 September 2016 (UTC)
- You are incorrect. I addressed some of your invalid points above and in the talk about the entry on Zorn's Lemma in that talk page.172.88.206.28 (talk) 01:22, 24 September 2016 (UTC)
- You addressed some point that you believe to be invalid. As it happens and as a matter of verifiable fact, they were not invalid and your complaints were based on a misreading of the text in question. Magidin (talk) 03:50, 24 September 2016 (UTC)
- Wrong, again. Please, see the "talk" page.172.88.206.28 (talk) 22:26, 29 September 2016 (UTC)
Please do not modify prior comments that other people have already replied to. It makes it difficult to follow the discussion. Magidin (talk) 21:00, 23 September 2016 (UTC)

[edit] Please refrain from using talk pages for general discussion of the topic or other unrelated topics. They are for discussion related to improving the article in specific ways, based on reliable sources and the project policies and guidelines; they are not for use as a forum or chat room. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages. See here for more information. Thank you.
