Former good article Al-Kindi was one of the Philosophy and religion good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.


Al-Kindi isn't persian .... and Al-Kindi is drived from Kinda a great arab tribe.

since when Al-Kindi become a persian? he is from an arab tribe in yemen ... so please check this link before making any changes on the article: 00:52, 27 Jan 2005 (UTC)

Many Famous Arab Scientist and Thinkers are being falsely claimed persians!! If not stopped or at least hindered, the credibility of Wikipedia will heavelly suffer!! And this is not good neither for the arabs nor for the persians. Since both of them use this Free Encyclopedia for the promotion of their great cultures.

AL-KINDI he was a philosopher a mathematician and astronomer, when the famous scientist like Galileo and NEWTONS they said that all physical laws are absolute but al-kindi said all physical laws are relative,, the theory of relativity was truly discovered by AL-KINDI not ALBERT EINSTIEN but unfortunately we don't know the al-kindi we just recognized einstien ,,, al-kindi is a person who basically gives the idea of theory of relativity, later on he did more discovered and told about theory of relativity,, — Preceding unsigned comment added by (talk) 08:07, 25 June 2013 (UTC)

"number system"?[edit]

What is meant by this term where it appears in this article? Is it about a particular numeral system (in which case it is mis-directed and should be changed to numeral system) or about something else (what?)? Michael Hardy 01:10, 2 Jun 2005 (UTC)

Peculiar recent edits[edit]

Perhaps the oddest is the insistence that al-Kindi was Christian; where exactly does this claim come from? --Mel Etitis (Μελ Ετητης) 12:03, 6 August 2005 (UTC)


Actually, most sources I've read insist that he was a Muslim.Heraclius 15:01, 6 August 2005 (UTC)
Of course there are a lot of muslim websites that would like to portray him as a Muslim to perpetuate a myth of a great Islamic philosopher, but no , he was a Christian.--CltFn 15:14, 6 August 2005 (UTC)
So you have most websites calling him a Muslim, but one or two calling him a Christian. Until this dispute is solved, I will just stick with the "Arab" description.Heraclius 15:15, 6 August 2005 (UTC)
Well why do you not read The APOLOGY OF AL KINDY IN DEFENCE OF CHRISTIANITY AGAINST ISLAM for starters?--CltFn 15:24, 6 August 2005 (UTC)

Have you actually read the text to which you link? Try reading the introduction by its translator. It's a different al-Kindi... Why are there so many anti-Islamic bigots on Wikipedia at the moment? They seem to crop up everywhere. A "myth of a great Islamic philosopher" indeed! Every book on the history of philosophy includes al-Kindi, and correctly describes him as an important Islamic philosopher. No-one considers al-Kindi to be one of the greatest Islamic philosophers, mind you, though he's in the top ten, perhaps the top six. --Mel Etitis (Μελ Ετητης) 16:18, 6 August 2005 (UTC)

Maybe this will help: [1] from the Wikipedia entry on Cryptanalysis
The line in the middle reads: "والحمد لله رب العالمين وصلى الله على نبيه محمد.." or "..And praise to Allah, and may peace be upon His prophet Muhammed". I suppose that should be conclusive.
I too observe this anti-Islamic bigots phenomenon.. It's very sad.

Why are there so many anti-Islamic bigots on Wikipedia at the moment? This may explain it [2].Heraclius 16:55, 6 August 2005 (UTC)
Yes; how depressing. Mind you, it's a symptom rather than a cause. --Mel Etitis (Μελ Ετητης) 18:43, 6 August 2005 (UTC)

It is called Peer Review. When information is not seen as accurate or impartial it is challenged by fellow editors and corrected. This process takes place on both sides of any given topic in Wikipedia. The question I would ask is why is it that whenever one challenges any assertions in Islamic related topics the source of the challenge is immediately labelled a bigot or an Islamophobe particularly by Muslims.? --CltFn 08:26, 7 August 2005 (UTC)
  1. In what sense are you a peer in this case? You insisted on an obvious mistake on the basis of one document which you hadn't read... I mean, I've read some poor referee's reports from academic journals, but rarely anything like that. (Note, incidentally, that Wikipedia:Peer review means something specific.)
  2. I don't use the label immediately; in this case, I used it when you made giveaway comments ("there are a lot of muslim websites that would like to portray him as a Muslim", when the references are to two non-Muslim books on philosophy, and "to perpetuate a myth of a great Islamic philosopher"), though the extreme flimsiness of your evidence coupled with your certainty and obduracy helped. --Mel Etitis (Μελ Ετητης) 09:03, 7 August 2005 (UTC)

Correct name of Al-Kindi[edit]

The complete name of Al-Kindi in Arabic characters is أبو يوسف يعقوب ابن إسحاق الكندي . It was wrong in the previous edition ("abu ya'qub yusuf" instead of the correct form "abu yusuf ya'qub").

Very accurate name and ancestry information (34 generations) is in the following Arabic page:

Quotes on Al-Kindi[edit]

The exact words of what Ibn al-Nadim said about al-kind is not repeated. Why in the world do you keep deleteing it??!!! Jidan 18:37, 6 March 2006 (UTC)

  1. Calm down.
  2. The quotation adds nothing to the article; it says nothing that isn't already said. It's one of many, many possible quotations from writers who say the same thing.
  3. Why did you revert all my careful changes of characters with diacritics? --Mel Etitis (Μελ Ετητης) 19:31, 6 March 2006 (UTC)
Mel Etitis, I really appreciate your effort in maintaining the qualtity of this article. In this article, al-kindi, is mentionend as the "philosopher of the arab" (by arab is meant arab-speaking not arab ethnic, this should be mentioned in the article), but by whom? and when? I have other qoutes on al-kindi from german and english scientists on al-kindi, will you keep deleting them? Jidan 20:28, 6 March 2006 (UTC)
In fact the article says: "he was often referred to simply as 'the Arab philosopher'" (by which was meant, according to all my sources, ethnic Arab — another reason that calling him Persian is anomalous). That's the point, of course — he was often referred to in that way; I know of no reason to suppose that Ibn al-Nadim was the first person so to refer to him. If he was the first, though, then that is better mentioned in the article. Generally speaking, it's much better to add important material to the article than to stick it into a quotations section. Would you mind placing the quotations you have in mind here, so that we can discuss how best to incorporate them into the article? --Mel Etitis (Μελ Ετητης) 22:48, 6 March 2006 (UTC)

Good article nomination[edit]

TheGrappler nominated this article for Good article status, & I must sadly write that while it is better than many articles on Wikipedia, it fails to pass the bar for being considered a "Good article". The reasons include:

  1. The article states that he is "the greatest philosopher of Arab descent", yet the explanation for this value judgement only gets one short paragraph. More space is devoted to his accomplishments in medicine.
  2. This article needs a more clear attribution of claims. In one passage, this article states that "al-Kindī was the first pharmacologist to determine and apply a correct dosage for most of the drugs available at the time" -- an important point, yet this statement needs an authority to confirm it. Although there are 2 sources cited at the bottom, it is not clear how their writings relate to the details given here; even to say "John Doe believed that X" -- then list the publicaiton where John Doe made this claim under "References" would be an improvement.
  3. A glance at this Talk page shows that the accuracy of the article is still under debate.
  4. And lastly, for such an important person, the article is surprisingly light. I'd really expect to find a more full discussion of this interesting person. -- llywrch 01:08, 17 April 2006 (UTC)

Restarting the work on al-Kindi[edit]

Hi everyone,

When I came across the al-Kindi article, I thought it would benefit from some attention.

My initial assessment of it was that what was already there was good. However, I considered two things:

1) What needs improving: it needs referencing and in places correcting (if you read Richard Adamson, he says Kindi actually set out to merely introduce Greek thought to the Islamic world, but ended up reinterpretting alot of it in a very original manner - the article says he was unoriginal!).

2) What needs adding: more work needs to be done on his contributions to Islamic Philosophy and his specific ideas in certain areas. It would also be good if we could do likewise with his contribution to the sciences.

This should hopefully get al-Kindi recognized as a "good article"!

If anyone has any ideas, please feel free to post them up.

Alexander.Hainy 19:53, 5 January 2007 (UTC)

Ok, lots added to both philosophy and scientific contributions, references from no less than three seperate academic books (although if anyone could add some more it would be great!), I think this article is on track to becoming a "good article". After I add the sub-section on optics to the section "Contributions" I think I might try to get it put forward. Alexander.Hainy 10:03, 7 January 2007 (UTC)

some notes for improvement[edit]

the article has wondeful potential to become a good article and maybe even a featured article, especially because of the significance of this personality in the light of Islamic philosophy. there are some things needing improvement if the article is to attain GA status.

  • there is no citation for the reference to Black, it seems. The notes refer to "Black, page X" but the work itself by Black (and is that Deborah Black as earlier mentioned?) is not specified so far as I could see in a text search for "black" in the page. (note by ecsd)—Preceding unsigned comment added by (talk) 02:23, 28 September 2008 (UTC)
  • per WP:LEAD, the introduction should be comprehensive enough to quickly overview and "sum up" the article as well as the topics discussed therein.. take a look at some FA-class biography articles to see prime examples of how such is achieved.
  • when introducing academics, include something very brief about who the academic is. for example, "According to Henry Corbin, professor in Islamic studies, Al-Kindi was born in Kufa ..." or something like that, from then on he can be referred to simply as Corbin where mention of him is appropriate. the point of this is for ease of reading, you ideally don't want readers having to open a new window to find out who Corbin is (making things more arduous than necessary) when you can succinctly give the reader the essential information within the article.
    • as a sub-point to this, if you are making statements of fact upon which there is no academic dispute, you can get rid of mentioning the academic altogether and (for example) simply say "Al-Kindi was born in Kufa ...". attribution becomes important when elements of individual opinions (i.e. which may be disputed) are involved. this doesn't seem to be much of a concern in the article however.
  • from what i could gather in my quick overview, the article says very little about the criticism he must have received, especially from traditionists of his time, as well as the asha'rites and hanbalites of later times. i only managed to find one line which discussed opposition (i.e. that of Ghazzali and his response to the philosophers), although i am sure academics must have covered opposition to him in more depth than just this.
  • please be sure to comb through the article with the manual of style, its biography supplement, and the guide on writing better articles

i haven't gone into too much depth over content issues as i've only briefly scanned over the article, but it's been given B-class status (upon the threshold of GA i would imagine), and i would definitely recommend submitting it for a formal peer review and perhaps re-enlisting it as a GA candidate afterwards. ITAQALLAH 18:20, 8 January 2007 (UTC)

Thankyou very much for your helpful feedback ITAQALLAH, we'll do our best to implement your suggestions (hopefully a section on "controversies") and then submit it for peer review.
Thanks again! Alexander.Hainy 02:38, 9 January 2007 (UTC)

Peer review[edit]

Thinking of submitting the article for a peer review, any thoughts/suggestions/objections? Alexander.Hainy 01:00, 10 January 2007 (UTC)

Article's name[edit]

The article should not use a strict transliteration for its name. According to WP:AMOS, an article's name should be a primary transliteration, or a standard transliteration if no primary transliteration exists. This article uses a strict transliteration in the lead too, which should be really fixed, if you are considering nominating it as a GA or even requesting a peer review. The article should be moved to Al-Kindi, the primary transliteration, and the lead should be fixed and changed in compliance with WP:AMOS. Should I proceed and do that, or does anybody have another thought? ← ANAS Talk? 12:48, 10 January 2007 (UTC)

I agree with your assessment. Please go ahead and make the necessary alterations to the article :-) thanks for letting us know about that! Alexander.Hainy 13:05, 10 January 2007 (UTC)
I moved the page, modified the lead, added the full script, and used a more accurate transliteration. Corrected many typos on my way. Only problem is there's a big gap between the subject's name in the lead and the Arabic script. :-/ Would you like to shorten the name to make it look better, or just leave it as it is? ← ANAS Talk? 13:54, 10 January 2007 (UTC)
On text-size medium there isn't a gap between the lead and the arabic, does wikipedia have any specific policies relating to this? I think it is important to keep the full name if at all possible, as this is how he would have been known in his works. Any thoughts?
Thanks again for your all your help! Alexander.Hainy 17:09, 10 January 2007 (UTC)
I interchanged the script and the strict transliteration. I think this is a harmless and fine way, and the gap is gone. Article's looking good; You can request a peer review if you don't have any more work/expansion left in the article. After that, the article will probably have a good chance at becoming a good article. All the best mate! ← ANAS Talk? 18:14, 10 January 2007 (UTC)

Article ready?[edit]

I think the article is ready for a re-review! Alexander.Hainy 12:21, 20 January 2007 (UTC)

I couldn't see the point of removing the (grammatically and stylistically necessary) definite article froma couple of the headers, nor the effort to banish "also" from the article (in a number of places it was again grammatically correct, and the changed version either less or at least no more clear.
Also, please use edit summaries. --Mel Etitis (Μελ Ετητης) 12:44, 20 January 2007 (UTC)
Alexander, there are some suggestions from the current peer review you haven't implemented yet. A quick look shows that you have not changed the varying spellings of the subject's name to the correct spelling. Also, you have the links and the other names like al-Farabi, which is spelled differently in the article. Perhaps you should check if you have applied all the suggestions in the current PR first. Good luck! ← ANAS Talk? 13:00, 20 January 2007 (UTC)

Alexander.Hainy: you need to look here for explanations (and give explanations here, too). I reverted most of your edits as you gave no explanation for them, not even edit summaries. --Mel Etitis (Μελ Ετητης) 16:36, 20 January 2007 (UTC)

Thanks for the feedback guys. Sorry about the edit summaries Mel, will remember that in future. I had removed "also" and the definite article in titles at the suggestion of the peer review. I would really appreciate it if you could have a look at the peer review page and flag those suggestions which you feel best be disregarded.
Thanks again, I will review the peer review page and make sure I haven't missed anything.Alexander.Hainy 16:51, 20 January 2007 (UTC)
Mel, you have not provided any explanation why you have changed the name of al-Farabi again. As I said on the edit summary, I have corrected the transliteration. Several other editors have been kind enough to keep the article tidy without leaving an explanation on the talk page. I didn't realize it was necessary to leave a summary on the talk page, so please forgive me for the oversight.
Thanks Alexander.Hainy 16:58, 20 January 2007 (UTC)

"Misspelling"? Throughout this Talk page lately, there's been a curious unargued agreement that a certain spelling of "al-Kindī" and other names, which ignores normal Wikipedia practice (to use the most common accurate form of a name) and, in calling one of the most common forms "wrong" and "misspelt" (as below) and therefore changeable without explanation, also goes against Wikiquette.

In what sense are these forms wrong? They're used in most of the modern sources at which I've looked. Debates at related pages have been resolved in favour of this sort of transliteration; I haven't checked yet, but I expect that consensus has been overturned by this new and (to my mind, at least) unwelcome approach. --Mel Etitis (Μελ Ετητης) 21:38, 20 January 2007 (UTC)

Ahah! I think I see the mispelling of al-Kindi... its in that blue box :-P Alexander.Hainy 17:08, 20 January 2007 (UTC)

OFFICIAL APOLOGY: Sorry, there is al-Kindī everywhere! I am correcting it now ;) sorry Anas, you were right! Alexander.Hainy 17:17, 20 January 2007 (UTC)

No worries mate. ;) ← ANAS Talk? 17:51, 20 January 2007 (UTC)

Article name argument[edit]

Mel Etitis, I didn't understand your last comment well, but I think we have an issue with the naming of the article. Perhaps it's just a misunderstanding. All guidelines, discussions, and consensus are in favor of using a common, primary transliteration for an article's name. Al-Kindi is, in this case, the more common and used name. A Yahoo! search yields 433 results for Al-Kindī and 212,000 results for Al-Kindi, where it also recognizes him and provides search filters. A staggering margin, eh? Also in published media, see here. Furthermore, it is never favored to use a strict transliteration for an article's name. It is both uncommonly used and difficult to use. Do you have another opinion? :-)

By the way, I have never said these spellings, or more accurately transliterations, are wrong. I'd have to say, I would be slightly offended by your comments if they were pointed towards me. ← ANAS Talk? 12:53, 21 January 2007 (UTC)

Yahoo or Google searches show what's most common on the Internet; the use of diacritics and other symbols is much less common on the Internet than in published sources, in which "al-Kindī" is much the more common transliteration. Little or no discussion was offered on this, above — the claim was simply made that "al-Kindi" is standard. Just pulling recent general reference books books off my shelf, the following use "al-Kindī" (I didn't find one that used "al-Kindi", except for a book dating from the 1970s):
  • Carr & Mahalingam [edd] Companion Encyclopedia of Asian Philosophy (Routledge, 2001)
  • Dronke [ed.] A History of Twelfth-Century Western Philosophy (CUP, 1992)
  • Deutsch & Bontekoe [edd] A Companion to World Philosophies (Blackwell, 1999)
  • Flew & Priest [edd] A Dictionary of Philosophy (Pan, 1984)
  • King One Hundred Philosophers (Barrons, 2004)
  • Watt Islamic Philosophy and Theology (Edinburgh UP, 1987)
In the discussions above, I should also note, are various references to "al-Kindi" being a misspelling, including your own reference to "al-Kindi" being "the correct spelling". --Mel Etitis (Μελ Ετητης) 13:08, 21 January 2007 (UTC)
You said it yourself, "the use of diacritics and other symbols is much less common on the Internet". As much as the references you provided are significant, the 800-something books in an Amazon book search and the Yahoo search results do have their significance too. You can't treat Wikipedia the same way printed references are treated; for example, any English user will probably search for al-Kindi, not al-Kindī when he looks for information online. This issue has been discussed deeply in many talk pages. As an example, see the recent debate in Shia Islam talk page. I, myself voted 'support' for the strict transliteration and 'weak support' for the standard English transliteration, but I now know it is, although inaccurate, the preferred transliteration.
When I said al-Kindi was the correct spelling, it was logically obvious that I meant it was the spelling supposed to be used throughout the whole article. Anyways, this is not the real problem here. ← ANAS Talk? 14:06, 21 January 2007 (UTC)
  1. Internet sources are often inaccurate, misrepresenting (for example, by omitting diacritics) the titles of and quotations from books and papers.
  2. "any English user will probably search for al-Kindi, not al-Kindī" that's what redirects are for.
  3. We should be representing most common best practice, not most common poor practice. --Mel Etitis (Μελ Ετητης) 14:18, 21 January 2007 (UTC)
Mel, I agree with your points, believe me (see my votes/opinions in the Shia Islam debate), but I am only working according to the consensus. Personally, I would definitely love to name every article accurately, but then again this isn't my encyclopedia. :) Remember there are thousands of articles with Arabic names that are rendered somehow inaccurately, like Saddam Hussein (Ṣaddām Ḥusayn). Perhaps a poll should be started to gain consensus for naming this article, what do you say? :) ← ANAS Talk? 15:07, 21 January 2007 (UTC)

The policy has always been that we use the most common and readily understandable form (as used in English-language publications). That's overwhelmingly "Saddam Hussain", not Ṣaddām Ḥusayn, but in cases like this one, where the person is referred to almost solely in academic or semi-academic works, the most common academic or semi-academic form is used. In other words, we don't have, and have never claimed to have, a consistent method of transliteration; it depends upon the individual case.

A poll is a last (and much deprecated) resort. A formal discussion of a renaming proposal would be fine, though. --Mel Etitis (Μελ Ετητης) 15:36, 21 January 2007 (UTC)

Fine, I agree, you can start a rename or move proposal if you'd like to. All the best. ← ANAS Talk? 16:08, 21 January 2007 (UTC)

Article renaming[edit]

The following discussion is an archived debate of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the debate was No consensus Duja 09:21, 9 February 2007 (UTC)

The article was renamed from Al-Kindī to Al-Kindi without sufficient discussion or reason. rather than simply move it back, could intersted parties explain here which name they think that it should have, and why? remember, this is not a vote, it's a discussion, so reasons are what count. Wikipedia:Naming conventions#Use common names of persons and things states: "Convention: Except where other accepted Wikipedia naming conventions give a different indication, use the most common name of a person or thing that does not conflict with the names of other people or things."

  • Change. I've given above a list of (recent) publications, none of them very specialised, which use the "al-Kindī" form. I found one older text that used "al-Kindi", and some references to mediæval texts that followed theoir usage of "Alkindi". "Al-Kindī" is the most common form in printed texts; as it's a name that's almost only found in academic or semi-acadmic texts, the most common usage in those is what's required. (Usage on the Internet is misleading; our preferred usage of "Pelé", for example (as listed at the naming conventions page) would have to be changed if we went by a Google search.) --Mel Etitis (Μελ Ετητης) 16:34, 21 January 2007 (UTC)
  • Keep While there are sources that use "Al-Kindī", they are only a minority. Al-Kindi is a primary transliteration. It is used more commonly both in published and online sources. A large results margin (see above discussion) found using Yahoo search goes in favor of the transliteration Al-Kindi. Also a Google Book search yields 798 results for books using "Al-Kindi" and only 61 results for "Al-Kindī". Encyclopedia Britannica uses al-Kindi. The guidelines state that a primary transliteration, one used by 75% or more of the references, should be used if available. Al-Kindi is clearly the primary transliteration since it is much more widely used everywhere. While I would love to go with a more accurate title, it simply wouldn't satisfy the consensus. ← ANAS Talk? 19:52, 21 January 2007 (UTC)
    Note that some, at least, of the books listed at "798 results for books using 'Al-Kindi'" in fact use "Al-Kindī". From the first page of the search: Al-Kind-I's Metaphysics by Alfred L. Ivry, Commanding Right and Forbidding Wrong in Islamic Thought by Michael A. Cook, Alfarabi and the Foundation of Islamic Political Philosophy by Muhsin Mahdi; in other words, a third of the books on that page use "al-Kindī", even though they come up on Google as using "al-Kindi", and the Google text sometimes presents them as using "al-Kindi". That's the problem with relying on Internet searches (as Arabic MOS says: "Google searches can be useful in determining the most common usage, but should not be heavily relied upon".) --Mel Etitis (Μελ Ετητης) 23:05, 21 January 2007 (UTC)
    They are very few. I searched through the first 6 pages and all had "Al-Kindi". Furthermore, Al-Kind-I's Metaphysics clearly uses "Al-Kindi" in its text, al-Farabi's book by Mahdi uses Al-Kindi, and Commanding Right and Forbidding Wrong in Islamic Thought uses "Al-Kindi" too. ← ANAS Talk? 03:31, 22 January 2007 (UTC)
    I'm afraid that you need to look more closely; I've just rechecked, and all three books that I mentioned clearly use "al-Kindī". You did look at the text of the books, not just at Google's incorrect text, didn't you? --Mel Etitis (Μελ Ετητης) 10:07, 22 January 2007 (UTC)
    Hmm, I didn't and I can't. My connection is too slow. But anyway, I guess they're still fewer than those using "Al-Kindi". ← ANAS Talk? 11:37, 22 January 2007 (UTC)
    Well, that's my point; if you go by what Google, et al., say, you'll get a skewed view of what's out there. They misrepresent books and articles by simplifying the text. Guessing that one usage is more common isn't good enough. --Mel Etitis (Μελ Ετητης) 11:50, 22 January 2007 (UTC)
  • keep as Al-Kindi. The Arabic MOS is clear on naming conventions. The standard version that wikipedia uses would be Al-Kindi, with no accent markers for long vowels. There are several reasons why, but the most simple one for this debate is for standardization across all the Islam related articles. Cuñado Bahai star.svg - Talk 21:56, 21 January 2007 (UTC)
    But, as I pointed out above, our naming conventions don't demand consistency; they demand that we use the most common form. As the MoS states: "A name has a primary transliteration if at least 75% of all references in English use the same transliteration"; there's no evidence that 75% of English sources use "al-Kindi" (I'd say that "al-Kindī" came closer to that). --Mel Etitis (Μελ Ετητης) 23:05, 21 January 2007 (UTC)
  • I would vote keep per Anas Salloum. - Darwinek 13:15, 22 January 2007 (UTC)
    Despite the fact that I've demonstrated that his figures are faulty? --Mel Etitis (Μελ Ετητης) 13:46, 22 January 2007 (UTC)
    Ah, I see that Anas Salloum asked you to join in, together with others. I'll bring this to the attention of WP:AN/I. --Mel Etitis (Μελ Ετητης) 13:52, 22 January 2007 (UTC)
    What? I have only invited him to join a discussion, since I know he has a fair understanding of Arabic. I have invited a few others too, it's normal. I have not asked him to vote keep, it's his opinion. My God, please assume good faith. Why are you making this me-versus-you? If inviting others for a discussion (since it will probably not be noticed) is considered wrong, I am sorry! I have been invited to discussions several times and I thought it would be OK. ← ANAS Talk? 14:33, 22 January 2007 (UTC)
    I didn't think of it in that way until I noticed that you'd asked a number of people hitherto unconnected with the article to join the discussion, without mentioning that here (which always used to be the courteous thing to do; perhaps things have changed). If I'm wrong, then I'm sorry. I don't really see what an understanding of Arabic has to do with this discussion, but that's another matter. --Mel Etitis (Μελ Ετητης) 16:10, 22 January 2007 (UTC)
    Just so you know I am not canvassing. Also, I hardly know any of the editors (which were 4 only, by the way) that I sent my invitations to, and with Darwinek, my interaction has been recent and brief. I am and have always assumed good faith and am not one of those editors who would do anything to illustrate a point. Regards, ← ANAS Talk? 03:36, 23 January 2007 (UTC)

    No, no. I mean, my support is based rather on WP:AMOS arguments. Still, I am opened to both solutions. - Darwinek 13:54, 22 January 2007 (UTC)

  • I prefer "al-Kindi" --Striver - talk 15:31, 29 January 2007 (UTC)
    Um, well, that's nice, but why? This is a discussion, not a vote or an expression of personal taste. --Mel Etitis (Μελ Ετητης) 15:38, 29 January 2007 (UTC)
  • Move Use of overdashes is widely used in scholarly, and even quality popular literature (in the case of al-Khwārizmī definitely more than 75%) and is therefore the primary transliteration. Web pages are not a reliable source to find out common usage, due to technical restrictions which prevent(ed) people from using diacritics. —Ruud 09:45, 31 January 2007 (UTC)
  • On the whole, I prefer Al-Kindi without diacritic, in the title. The three books Mel cites from the Google books use macrons for all Arabic names, without discrimination; this is not Wikipedia style. (One of them references Al-Kindi only by full name and only in footnotes, which are often more pedantic than main text; our article titles should be less pedantic than main text.) I would read WP:AMOS as recommending the simple form when it is clear what that simple form is, as here. Septentrionalis PMAnderson 22:57, 31 January 2007 (UTC)
    "footnotes, which are often more pedantic than main text"? --Mel Etitis (Μελ Ετητης) 23:18, 31 January 2007 (UTC)
    Yes. In a field more familiar to me, footnotes will often include untranslated Greek, when the text always translates; or Greek in the Greek alphabet, where the main text transliterates. Don't Arabists work the same way? Septentrionalis PMAnderson 00:55, 1 February 2007 (UTC)
    I've no idea; I'll ask (my College has two Arabists, whom I should see at lunch today). It's not really relevant to this question, though; I've never seen a text in any subject area in which a name is printed differently in the text and the footnotes. --Mel Etitis (Μελ Ετητης) 09:15, 1 February 2007 (UTC)

Al-Kindi and gravitation[edit]

I recently flagged the statement that "Al-Kindi stated his law of terrestrial gravity" with the template that "this source's reliability may need verification," since the only source was the historical introduction to a physics text which. In areas where it was possible to check this book's other claims, they turned out to be historically inaccurate.

I have since checked the article on Al-Kindi by Jean Jolivet and Roshdi Rashed in the Dictionary of Scientific Biography and found no mention of al-Kindi's teaching on gravitation. George N. Atiyeh, in his Al-Kindi: Philosopher of the Arabs, (Rawalpinidi: Islamic Research Institure, 1966), p. 85 presents a description of al-Kindi's view as the conventional Aristotelian one in which heavy bodies, such as the Earth, move downward toward the centre and light bodies, such as Fire, move upward away from the centre.

I will remove the claim here and in other places where it appears. --SteveMcCluskey 19:10, 24 June 2007 (UTC)


I'm deleting the section on relativity. The only source brought is from an evangelical religious website which seems quite biased, including claims that the theory of relativity is is found in ancient religious works, and dubious claims about Einstein's religiosity. If anyone wants to find a scholarly source for the claim that Al-Kindi's theories were a precursor the theory of relativity, they can reinstate it. Zachen3 (talk) 15:06, 31 July 2008 (UTC)

Cardano:: "Al-Kindi one of twelve greatest minds"[edit]

The Italian Renaissance scholar Gerolamo Cardano (1501–1575) considered [Al-Kindi] one of the twelve greatest minds of the Middle Ages...

Al-Kindi was certainly a great mind (as was Cardano) and my comment is not about this page. My question is: Does anyone know who Cardano's other eleven "great minds" were? I've Googled and Googled and Wiki'ed and Wiki'ed but only ever find that "Al-Kindi was one of twelve." Just curious. Jamesdowallen (talk) 21:34, 6 February 2010 (UTC)

I realize this page is not the appropriate venue for the fact, but I did finally get my question answered via;dir=hutto_dicti_078_en_1795;step=textonly
Quote: Those 12 persons were, Euclid, Archimedes, Apollonius Pergæus, Aristotle, Archytas of Tarentum, Vitruvius, Achindus [Al-Kindi], Mahomet Ibn Moses the inventor or improver of Algebra, Duns Scotus, John Suisset surnamed the Calculator, Galen, and Heber of Spain.
(Googling en-route to this discovery, I also learned that Ptolemy may have been on an earlier version of Cardano's list.) Jamesdowallen (talk) 06:00, 17 February 2010 (UTC)

Problematic sources[edit]

The claim in this article about al-Kindi's work on the tides references (which has reliability problems) but I think the material comes from:

Dunlop, D. M. (1971). Arab Civilization to A.D. 1500. Arab Background Series. Longman. 

Next time I'm at the relevant library, I'll check this and replace the reference as appropriate.
The article also uses the History of Science and Technology in Islam website, which is self-published by Ahmad Y. al-Hassan. My memory of the relevant discussion at WP:RSN is that this site can be used but with qualifications, i.e. if the claim is at all exceptional, note its source; otherwise the author is an accepted, if perhaps heterodox, authority in this area.
All the best. –Syncategoremata (talk) 17:10, 31 May 2010 (UTC)

I have addressed a couple of issues in the article and have commented on the reassessment page. I encourage members of this wikiproject to participate in the article's improvement to preserve its status as a Good article. --Al Ameer son (talk) 04:04, 23 March 2011 (UTC)

Unfortunately, you seem to have erred. You added:

Al-Kindi is credited with inventing the pinhole apparatus which was an early form of the camera obscura. He used it as a research tool.<ref>Ogbourne, Derek. Encyclopedia of Optography. Muswell Press. p. 179. ISBN 0954795946. </ref> Using a ray model, al-Kindi also described the formation of shadows and images in the camera obscura.<ref>Wellington, Jerry J. (1994). Secondary science: contemporary issues and practical approaches. Psychology Press. p. 263. ISBN 0415098440. </ref>

but a glance at the camera obscura page shows that it far predates Al-K William M. Connolley (talk) 09:54, 23 March 2011 (UTC)

I didn't write, or at least didn't intend to write, that he invented the camera obscura or he invented the first form of the camera obscura. From memory, the source for the first sentence mentions Ptolemy had used it before him. Like I had stated in the reassessment page, I don't know much about this topic. However, I provided the exact url in the source. Could you please read it and then clarify the info in this sentence. Also, I don't know why you removed the second sentence which says Using a ray model, al-Kindi also described the formation of shadows and images in the camera obscura. --Al Ameer son (talk) 21:54, 23 March 2011 (UTC)
The problem is that the CA page says it was invented earlier (who knows, it may be wrong, but then we have much more to clean up). So saying that he invented an early form of something invented much earlier is a problem. You have to be careful: apparently reliable sources say wrong things, sometimes William M. Connolley (talk) 23:18, 23 March 2011 (UTC)

Perhaps, but the source used for the first sentence (Encyclopedia of Optography) appears reliable and it's not centered on al-Kindi. It just mentions one of his contributions. The exact words from the source reads: Optical science reached a high point in the work of Claudius Ptolemy, after which it was forgotten until its revival by the Arab scientist al-Kindi, who introduced the pinhole apparatus, an early form of the camera obscura, as a research tool. Investigations into the functioning of the eye and the pinhole effect continued during the golden age of Islam, reaching a peak in the work of Ibn al-Haitham ... Also, I still do not understand the concerns for the second sentence that was removed. Could you clarify this for me? --Al Ameer son (talk) 00:02, 25 March 2011 (UTC)

So, this looks like classic Jagged misrepresentation of sources. He takes a source that basically says Al-K revived something, and makes it say he invented it. That is wrong. The second sentence isn't obviously wrong, but with the first sentence removed it isn't terribly interesting in itself: it just says he did something others had previously done. Now that, integrated into a coherent view of his work, might be worth saying. As a stand-alone factoid it is odd William M. Connolley (talk) 08:16, 25 March 2011 (UTC)

Stub and rework[edit]

For background information, please see RFC/U and Cleanup. With 128 edits, User:Jagged 85 is the main contributor to this article after May 2007 by far (2nd with 22 edits is William M. Connolley who did clean-up work). The issues are a repeat of what had been exemplarily shown here, here, here or here. I restore the article to the first pre-Jagged version on 2 May 2007 which seems fairly good plus the usual update on categories, templates, infoboxes etc. etc. Gun Powder Ma (talk) 10:17, 16 April 2011 (UTC)


The optics section looks dodgy, if

Thus, the De Aspectibus shows that al-Kindî favored an extramission view of vision, in which rays extend from the eyes to make contact with an object, enabling a person to see it.[2] Following Euclid's Optics ultimately, al-Kindî offers geometrical demonstrations against both the alternative “intromission” view, and the view that fuses extramission with intromission; views identified mostly with Aristotle's De anima and Plato's Timaeus, respectively. In other treatises, however, al-Kindî may be more sympathetic to Aristotle's understanding of vision, mixed with possible familiarity with relevant treatises of Ptolemy and John Philoponus. [4]

is to be believed William M. Connolley (talk) 21:39, 9 May 2011 (UTC)

Al-Kindis Music Theory[edit]

The informations in this paragraph are wrong.

There are a lot of music theorists who are supposed that they added the fifth string to the oud, among them also Ziryab, the student of Ishaq al-Mawsili.

Concerning Al-Kindi, this is a pointless and not very plausible speculation. His music treatise, not the ones which we do not know, but one of those which have survived, describes very clearly a four stringed oud. Based on his treatise, it has even been reconstructed by the Institute for the History of Arabic-Islamic Science at Frankfurt am Main (I recommend the publications by Eckhard Neubauer who studied Al-Kindis treatises and published their facsimile). Concerning music therapy, Al-Kindi also mentions in another book that these four strings had been coloured according to the four elements and its humours. This is the reason why Al-Kindi is explicitely associated with a very simple and early oud which has just four simple strings, not the five double strings as they are used today.

Another characteristic is that Al-Kindis terminology can be easily recognized as an Arabic translation of Greek terms and he mentioned explicitely his admiration of the Byzantine Octoechos system. This is astonishing, because most of the Ancient Greek treatises had been translated later into Arabic dialects, between the 9th and the 10th century. Al-Farabi's contributions clearly profited from them. Platonykiss (talk) 11:29, 10 January 2013 (UTC)

Born in Basra or Kufa?[edit]

"He was born and educated in Basra" (opening paragraph)

"Al-Kindi was born in Kufa [...] received his preliminary education there" (opening line under the chapter "Life")

Which one is correct? Ben tetuan (talk) 19:29, 1 October 2013 (UTC)

The former, according to Peter Adamson; the latter, according to Henry Corbin (or so I read the cited sources). Why, how do you understand them?—Jerome Kohl (talk) 20:24, 1 October 2013 (UTC)
