Abstract

Around the end of the ninth century, Ibn al-Rīwandī wrote a book entitled Adab al-jadal. About a generation or so later, Abū l-Qāsim al-Balkhī, known as al-Kaʿbī, also wrote a book on jadal in which he purported to correct errors that Ibn al-Rīwandī made in his work. This work was in turn refuted by al-Ashʿarī, the great theologian, who took up Ibn al-Rīwandī’s cause against al-Kaʿbī’s criticisms. So too another great theologian, al-Māturīdī defended Ibn al-Rīwandī. But of the works just mentioned, none survives.

    K. al-Anwār wa-l Marāqib, ed. L. Nemoy (New York: Alexander Kohut Memorial Foundation, 1939–43). Vajda and van Ess argue for this while Makdisi believes that he copied from Abū ʿIsā al-Rummānī (d. 994). But since al-Rummānī seems to have lived much later, it would appear that the former hypothesis is better. See G. Vajda, “Études sur Qirqisānī V,” Revue des Études Juives 122 (1963): 9.

    Ibn Fūrak, “Mujarrad,” fol.142a: 20. al-Kātib , al-Burhān, p. 225, line 5 ff.; p. 235, line 2 ff. al-Maqdisī, al-Bad’, p. 50, line 5 ff. This was evidently a topos of the early interconfessional debate literature. Cf. G. Bardy (ed. and trans.) “Les trophées de Damas: controverse judéo-chrétienne du VIIe siècle,” Patrologia Orientalis 15,2 (1920) p. 192, line 10. B.

    Ibid., fol.142b: 10–12; 142a: 5–11; 142a: 18–19. The problem of whether the world is eternal or not is Aristotle’s classic example of a dialectical problem. Top.104 b8. Vajda and van Ess have pointed out several instances in which theological jadal may have borrowed from Aristotle’s teaching on dialectic. However, they conclude that there has been no direct borrowing. Vajda, “Études,” 8 ff. Van Ess, “Disputationspraxis,” p. 52–3. We agree with this position.

This testimony adds support to van Ess’s thesis that this slogan played an important role in justifying the theological missionaries who held disputations in order to convert the non-believers. Van Ess, “Disputationspraxis,” pp. 50–1.

  16. 16.

    Could this distinction ultimately derive from Aristotle De Anima 433b29 where he distinguishes between two types of phantasia: aisthētikē and logistikē?

    al-Māturīdī, Kitāb al-Tauḥīd, ed. F. Kholeif (Beirut: Dar el-Machreq, 1970), p. 7, lines 7–8, says that “It is agreed that one should not argue with those who reject evidence of the senses (ʿiyān, lit. seeing).” He calls these people munkir or mukābir . On the latter term, cf. the signs of defeat below.

Dānishpazhūh (Tehran: Anjuman-i Shāhanshāhi-i Falsafah-iīrān, 1357), p. 67, line 9 ff.: “Some people contentiously objected (shaghaba) against what Aristotle said that…nothing is known except by syllogism (ṣanīʿa).” Cf. Yaʿqūb b. Isḥāq al-Kindī, Rasā’il, ed. M. Abū Rīda, 2 vols. (Cairo: Dār al-Fikr al-ʿArabī, 1950–3), vol. 2, p. 302, bottom.

    al-Qirqisānī , al-Anwār, p. 70, line 4 ff. He reports the argument of al-Maqdisī’ s sophists and rejects it since we know naẓar and qiyās per se. Qiyās is the “reducing of a thing to its equal (radduhū ilā naẓīrihī ),” and is in accord with necessary knowledge. Later (92, line 2 ff.) he notes that qiyās is based upon uṣūl that are not the result of qiyās. “Thus there is no infinite regress. This argument is similar to the one used with respect to acts of knowledge and intellectual analogy (i.e., syllogism) which are based on acts of knowledge derived from the senses.” In commenting on Aristotle, Ammonius notes, “One cannot bring syllogisms about either the noēta or the objects of sense; instead they are about the things that are neither the one nor the other (ta mesa). For the theologian is not able to prove the noēta through syllogisms, but he uses analogy and this is reasonable. For syllogisms prove from the cause to the effects and from the more general to the more particular. But the noēta are more universal and prior to everything else….Similarly we do not prove by syllogism the objects of sense—e.g., that milk is white, since we know them per se.

  27. 27.

    Cf. Ibn Fūrak, “Mujarrad,” fol.143a: 3 ff., “He said the meaning and essence of questioning (al-su’āl) are asking for information (istikhbār) .” Ibn Fūrak notes that this definition only applies to “dialectical questioning” since “questioning” has a much broader meaning. (It could mean “to beg.”) Cf. Abū Hilāl al-ʿAskarī, al-Furūq fī al-lugha, 2nd ed.(Beirut: Dār al-Āfāq al-Jadīda, 1977), p. 28, line -8 ff. al-Juwaynī , al-Kāfiya, p. 70, line l.

  28. 28.

    Cf. Ibn Fūrak, “Mujarrad,” fol.143a: 12–13: “the first question is about the opinion. It is asking ‘What do you say about that?’“

  29. 29.

    Ibid., fol.143a: 12-3: an yuṭāliba bil-dalāla ʿalayhī .

  30. 30.

    Ibid., fol.143a: -1: al-muṭālaba bi-wajh al-dalāla . Cf. Abu ʿAli ʿUmar al-Shakuni, ʿUyūn al-munāẓarāt, ed. S. Ghurab (Tunis: 1976), p. 25, #26.

  31. 31.

    Al-Bāqillānī in his Tamhīd illustrates this question when he argues against certain Muslims who maintain that events are influenced by the heavens in that God made them signify [dalāla] what would come about in the world during their various conjunctions. “This is nonsense [khabaṭ wa-takhlīṭ]. For if the sign [dalīl] is connected with the signified [madlūl] then the manner that it is connected [wajh al-taʿalluq] must be well known, as for instance in the way that the art of writing is connected with the writer and that the person who produces a piece of writing be [at that time] knowledgeable. Or as novel events signify what is unprecedented… and miracles the veracity of their authors and all such things where the manner of the connection between sign and signified is known.” This is not the case in astrology. Ed. McCarthy, p. 57–58. Cf. p. 209–210 [hādhihi ḥīra wa-qillat dīn wa-īthār lil-takhlīṭ].

  32. 32.

    The reference to the “manner of the connection” of the sign to the signified refers to this third “question” and is frequently found in reports of debate or even theological arguments of the kalam style. Thus the Qāḍī ʿAbd al-Jabbār argues that Scriptural injunctions [khiṭāb] signify that God is Omnipotent and All-Knowing, even though “the manner of its signifying [wajh dalālatihī] is based on God’s being …. Al-Mughnī, vol. XVII, p. 8.

  36. 36.

    Ibid., 30, line 12 ff.; trans. 27, line 12 ff. Cf. Ibn Fūrak, “Mujarrad,” fol.138b: 17 ff.: “He said that the meaning of dalīl and dāll was like that of ʿalīm and ʿālim in that the former derives from dalāla and just as ʿālim derives from ʿilm , so too does ʿalīm (derive from it). He said that dalāla is a sign (ʿalāma) whereby the signifier (al-dāll) indicates the significatum (madlūl ). This sign can be an indication (ishāra), effect (athar ), or a legal qualification that necessitates another (ḥukm muqtaḍā).”

  37. 37.

    al-Maqdisī , al-Bad’, p. 31, line 14 ff.; trans. 28, line 18 ff. Cf. van Ess’s discussion of this passage in “Logical Structure,” p. 36.

  38. 38.

    al-Maqdisī , al-Bad’, p. 35, line 11 ff.; trans. 32, line1 ff. al-Maqdisī’s reasoning here is reminiscent of Aristotle’s distinction between proof and cause in APo. 89 b21 ff.

  39. 39.

    al-Maqdisī , al-Bad’, p. 34, line 1 ff., 36, lines 10–11. Cf. Ibn Fūrak, “Mujarrad,” fol.139a: 5 ff. al-Ashʿarī calls this process istishhād . al-Fārābī discusses this procedure and identifies it with induction (istiqrā’) and applying the cause to the effect (ijrā’ ḥukm al-ʿilla fī al-maʿlūlāt a method used by “our contemporaries.” This method he says is of no use in establishing the judgment (ḥukm) although it is of use in destroying it. The method is not suited to jurisprudence since there such a strict procedure is deleterious. al-Fārābī, “Kitāb al- qiyās al-ṣaghīr,” ed. M. Türker, Ankara Üniversitesi Dil ve Tarih Cografya Fakültesi Dergisi 16 (1958) pp. 269 ff.; cf. p.282, line 11 ff. and 286, line 7 ff. Aristotle APr. Book II.24.

  40. 40.

    Al-Maqdisī , al-Bad’, p. 34, line 1 ff.; trans. 30, line 24 ff. Ibn Fūrak, “Mujarrad,” fol.140a: 8 ff. al-Ashʿarī gives several examples of this, one of which is that it “… is when a thing that is known (fī al-shāhid) has some attribute (ṣifa ) due to some cause and that there exists no sign (dalīl ) that a “thing given this attribute” (mauṣūf) “in the unknown” has it for any other reason that this very cause; then, it must necessarily be judged that everything “in the unknown” that has this attribute has it on account of that cause.”

  42. 42.

    Ibid., fol.151a: 18 ff. This passage is the only direct quotation from Ibn al-Rīwandī’s work. It is difficult to know exactly where this argument appeared in his work. It would seem possible that he had a chapter on arguing from the shāhid to the ghā’ib. One thing, however, is clear: the issues treated in the book were theological. Cf. ʿAbd al-Qāhir al-Baghdādī, Uṣūl al-Dīn (Istanbul: Maṭbaʿat al-Daula, 1928), p. 30, line 9 ff.; p. 36, line -1 ff. R.

  48. 48.

    ʿaqaduhū must be in the sense of iʿtaqadahū. Vajda translates “la faussete de sa construction,” in “Études,” p. 14, lines 7–8. But see Ibn Fūrak, “Mujarrad,” fol. 143 a: 15, “ka-naḥwi man ʿurifa min iʿtiqādihī wa-madhhabihī.”

  49. 49.

    Al-Qirqisānī , al-Anwār, p. 471, line 6 ff. Vajda, “Études,” pp. 13–4. For the lst question, Vajda refers to Aristotle Topics 110a29 ff. and APr. 40b17,55. However, there may be a Stoic influence. Van Ess has pointed out the relation between Stoic reasoning from signs (“Logical Structure,” pp. 26–9, 33–4). Here we are reminded of the criterion of connectedness, sunartēsis, that stipulates that x cannot be a sign for y if y, the signified, exists without it. See Philodemus, On Signs, ed. P. and E. de Lacy (Naples, 1978) in Philodemus: On Methods of Inference, (Naples: Bibliopolis, 1978), Vol. I, 1–19, p. 156, and 210. The de Lacys also refer to Galen XVIII B 640, 643–5. Cf. al-Qirqisānī , al-Anwār, p. 358, line 10 ff. Doubt and Dogmatism, ed. M. Schofield, M. Burnyeat, and J. Barnes (Oxford: Clarendon Press, 1980), index s.v. sunartēsis.

  50. 50.

    On this division, see below on juristic dialectic.

  51. 51.

    The Arabic word “dalīl” is notoriously difficult to translate, because it is used here as evidence, indication, sign or proof.

  52. 52.

    The Arabic words literally mean branches or branch out of and therefore are translated as “ramification” rather than consequence(s).

  53. 53.

    al-Qirqisānī , al-Anwār, p. 472, line 7 read: al-mushārika lahū fihā. Cf. al-Maqdisī, al-Bad’, p. 34, line 1. The reference is to analogical reasoning.

  54. 54.

    al-Qirqisānī , al-Anwār, p. 472, line 8 read: taqaʿu bi-tilka mas’alatun lāzimatun.

  55. 55.

    Ibn Fūrak, “Mujarrad,” fol.145b: -1 ff.: “He may ask him to apply it. This can occur as a sort of trick or on account of Q’s inability to dispute P’s cause, or his ignorance, or because he treats him lightly, or in order to annex to his cause some opinion that does not hold, or in order to force R, in the process, to reject evidence of the senses or intellect.” The above point may have been part of Ibn al-Rīwandī’s treatment.

  56. 56.

    al-Qirqisānī , al-Anwār, p. 471, line 16 ff. Vajda, “Études,” pp. 14–5.

  57. 57.

    Cf. above note 50 and compare the language of his four questions with that of al-Ashʿarī in notes 28–31 above.

  58. 58.

    Al-Kātib does not list the questions but he does mention them. Cf. al-Burhān, p. 225, line -2 (mā al-madhhab ); p. 227, line 8 ff. (ṭard al-ʿilla) ; p. 226, line 3 ff. (ṭalab al-ʿilla) .

  59. 59.

    Ibid., p. 235, lines 5–8; al-Kātib criticizes Ibn al-Rīwandī for arguing both sides of the question. But this criticism may be directed against his books in which he put plausible arguments in the mouths of opponents of Islam (in order to refute them?). Cf. J. van Ess, “Ibn al-Rīwandī or the making of an image,” al-Abḥāth 27 (1978): 5 ff.

  60. 60.

    al-Qirqisānī , al-Anwār, p. 472, line 13 ff. Vajda, “Études,” p. 16; at 16, line 7 read ḥajr for ḥasm. The distinction is also mentioned in Ibn Fūrak, “Mujarrad,” fol. 143b: 2ff. There it occurs after discussion of the “third question.” There is a curious parallel for this term in Alexander of Aphrodisias, In Aristotelis Topicorum libros octo commentaria, ed. M. Wallies, “CAG” vol. 2, pt. 2 (Berlin: G. Reimer, 1891), p. 540, line 10: ou gar apokleiei (!) hē proeirēmenē erōtēsis tēn toiautēn apokrisin.

    Of course, this only means that al-Fārābī probably follows Ammonius’s interpretaion.

Alexander of Aphrodisias, Topicorum commentaria, to Top. 101b23. In his commentary on the Topics al-Fārābī remarks, “Rhetorical and sophistical questions and objections are erroneously used in dialectic. Similarly, many people err in using epistemic questions in dialectical conversation although they are unaware of this….” al-Fārābī, fol.217a ff. MS.231 TE41, Bratislava, unpublished typescript of M. Galston. Aristotle, Ammonius, and al-Fārābī all speak of contradictory alterations. But the translator speaks of “two or more choices.” This mistake in translation left room for opponents of Aristotle’s logic to formulate their attack. The attack focuses upon the fourteenth chapter of Aristotle’s De Int. where Aristotle claims that the contradictory of any given statement is more contrary than the affirmation of the opposite of the original statement. That is to say the statement “John is just” is more contrary to the contradictory statement “John is not just” than it is to its proper contrary “John is unjust” where “unjust” is affirmatively predicated of John. This doctrine was subject to controversy among the philosophers; the theological attack has other grounds and far-reaching implications. On this attack, cf. Zimmermann, al-Fārābī, p. lxxxvi, cxxv. Van Ess, Frühe Muʿtazilitische Häresiographie, Zwei Werke des Nāshi’ al-Akbar (Beirut: F. Steiner, 1971), text 118, line 2 to 119, line 6. where at 118, line 12 read bi-ghairi juz’aihī. Cf. Ibn Fūrak, “Mujarrad,” fol.143b: 9–11: Q can posit a restrictive question in which R cannot answer by affirming a “part” of what he mentioned in his question. This is as when Q asks about someone who is neither sitting nor standing, “Is he standing or sitting?” and the only answer would be to say “He is neither standing nor sitting….”

They rely upon jadal and what first comes to the senses, or what observation judges, or whatever notions combined with fancy and imagination occur to them…. All this is connected with fallacious reasoning (mughālaṭa ) and repelling and silencing the opponent with whatever happens to be at hand….” Cf. 205, line 13 ff. al-Fārābī, Risāla fī al-ʿaql , ed. M.

    Ibn Fūrak, “Mujarrad,” fol.146a: 16–18. This passage also clears up the meaning of al-Maqdisī, al-Bad’, p. 32, line −2 ff: The person who has been subjected to muʿāraḍa must either reply or admit his inconsistency (read munāqaḍatihī); should he abstain from replying to the muʿāraḍa then R could abstain from answering any question since Q seeks information (read (mustakhbir) and the person subjected to muʿāraḍa must give information (al-muʿāraḍ mukhbir). Goldziher suggested reading mustajīb, mujīb in “Bemerkungen zu Huart’s Ausgabe des K. al-bad’ wal-ta’rīch von al-Balchī,” Zeitschrift der Deutschen Morgenländischen Gesellschaft 54 (1900): 400.

Further, in the beginning he seems to promise to define muʿāraḍa (p. 8, line -3 ff.). Cf. al-Qirqisānī , al-Anwār, p. 476, line 11: al-taswīya .

At the bottom of the page one should add: “fa-qul innahā muḥdatha li-anna ḥadathahā mutaṣauwar fī al-ʿaql fa-lā yutaṣauwar fī al-ʿaql mā lā ḥaqīqa lahū.” For al-ʿAskarī, see Sezgin, GAS 8, pp. 183–5. The method of muʿāraḍa is similar to that of the methodos kata sugkrousin of classical rhetoric, which consisted in placing the various charges of the plaintiff alongside one another and showing their inconsistency. R. Volkmann, Die Rhetorik der Griechen und Römer 2nd ed. (Leipzig: B. Teubner, 1885), p. 244, line 6 ff. Van Ess compares it with the methodos kata peritropēn in his “Disputationspraxis,” pp. 53–54.
