Natīd̲j̲a

(91 words)

Author(s): Boer, Tj. de
(a.), the usual name for the conclusion resulting from the combination of the two premisses ( muḳaddimāt ) in the syllogism ( ḳiyās ). It corresponds to the Stoic ἐπιφορά; this word in the works of Galen known to the Arabs is applied to the various discharges from the body but also means, as with the Stoics, the conclusion. Aristode used the words συμπέρασμα: that which concludes or completes the syllogism. In place of the usual natīd̲j̲a we also find ridf or radf ( = deduction). (Tj. de Boer)

D̲j̲ism

(1,555 words)

Author(s): Boer, Tj. de
(a.), body. In philosophical language the body (σῶμα) is distinguished from the incorporeal (ἀσώματον), God, spirit, soul, etc. In so far as speculation among the Muslims was influenced by Neo-Platonism two features were emphasized: I. The incorporeal is in its nature simple and indivisible, the body on the other hand is composite and divisible; 2. the incorporeal is in spite of its negative character the original, the causing principle, while the body is a product of the incorporeal. ¶ The more or less naive anthropomorphism of early Islam, i.e., the conception of God after the an…

ʿAḳl

(1,338 words)

Author(s): Boer, Tj. de | Rahman, F.
, intellect or intelligence, the Arabic equivalent to Greek νοῦς. (1) In neoplatonic speculation, which in many respects resembles the late Greek doctrine of the Logos and also in many respects corresponds to the Logos christology, ʿaḳl is the first, sometimes the second, entity which emanates from the divinity as the first cause, or proceeds from it by means of intellectual creation, nafs and ṭabīʿa etc. coming after ʿaḳl in succession. As first created entity the ʿaḳl is also called "the representative" or "the messenger" of God in this world. The neoplatonic idea of ʿaḳl as first crea…

Naẓar

(2,178 words)

Author(s): Boer, Tj. de | Daiber, H.
(a.), lit. “theory, philosophical speculation”, probably did not receive until the 9th century A.D. the meaning of research in the sense of scientific investigation as translation of the Greek θεωρία. With Aristotle, e.g. Metaph . 1064 b2 (translated by Eustathius/Uṣtāth at the beginning of the 9th century), and the Greek Prolegomena (Προλεγόμενα τῆς φιλοσοφίας) to the commentaries on Prophyry’s Isagoge , the philosophies were then divided into theoretical ( naẓariyya ) and practical ( ʿamaliyya ); the latter seek to obtain the useful or the good …

ʿĀlam

(3,100 words)

Author(s): Boer, Tj. de | Gardet, L.
(a., pl. ʿālamūn , ʿawālim ), world. 1. The word is found as early as the Ḳurʾān, where in borrowed formulae we have references to the rabb al-ʿālamīn and the seven samawāt . Allāh is its lord and creator who has created it for man as a sign of his omnipotence. This transitory world [ dunyā ) is of little value—"not worth the wing of a midge" is the traditional expression—in comparison with the next ( āk̲h̲ira ). We are told very little about the structure of the world [cf. the article k̲h̲alḳ ]; the subjects of interest, in the Ḳurʾān as well as in Tradition, are God, the spiritual world and man. This bec…

At̲h̲ar

(284 words)

Author(s): Goldziher, I. | Boer, Tj. de
(A.), pl. āt̲h̲ār , literally "trace"; as a technical term it denotes: 1) a tradition [see ḥadīt̲h̲ ]; 2) a relic : al-at̲h̲ar al-s̲h̲arīf (pl. al-āt̲h̲ār al-s̲h̲arīfa ), relics of the Prophet, hair, teeth, autographs, utensils al-leged to have belonged to him and especially impressions of his footprints [see ḳadam ]; these objects ¶ are preserved in mosques and other public places for the edification of Muslims. Relics are also called, both by Christians and Muslims, d̲h̲ak̲h̲īra ("treasure"). Bibliography I. Goldziher, Muh. St, ii, 356-68. For a description, with illustrati…

Ḳuwwa

(4,214 words)

Author(s): Boer, Tj. de | Arnaldez, R.
(pl. Ḳuwā ), Arabic term denoting “strength, power”. 1. Lexicographical study. Ibn Sīda defined the word ḳuwwa as the opposite of weakness ( naḳīd al-ḍaʿf ), cf. Ḳurʾān XXX, 54: “It is God who has created you from weakness ( min ḍaʿf ) and who then, after weakness, has given you strength ( ḳuwwa )”. It is thus the concept of strength and of vigour which is paramount. A man is described as ḳawī when he is strong in himself, and as muḳwī when he owns a robust mount. On the other hand, like the word ṭāḳa (which also has the sense of “ability to act”), ḳuwwa denotes a thread which is part of a rope. As …

Nūr

(2,653 words)

Author(s): Hartner, W. | Boer, Tj. de
(a.), light, synonym ḍawʾ , also ḍūʾ and ḍiyāʾ (the latter sometimes used in the plural). 1. Scientific aspects According to some authors, ḍawʾ ( ḍiyāʾ) has a more intensive meaning than nūr (cf. Lane, Arabic-English dictionary, s.v. ḍawʾ); this idea has its foundation in Ḳurʾān, X, 5, where the sun is called ( ḍiyāʾ and the moon nūr. The further deduction from this passsage that ḍiyāʾ is used for the light of light-producing bodies (sun) and nūr on the other hand for the reflected light in bodies which do not emit light (moon), is not correct, if we remember the primiti…

Faṣl

(489 words)

Author(s): Boer, Tj. de | Anawati, G.C.
etymologically, like farḳ , expresses the general meaning of separation or disjunction (for the various meanings, see LA, xiv, 35-9 for faṣl ; xii, 174-82 for farḳ; Abu ’l-Baḳāʾ, K. al-Kulliyyāt , 275). In logic, faṣl signifies “difference” and especially “specific difference”, the διαφορά of the five predicables of Porphyry (1. γενός, d̲j̲ins , genus; 2. εἶδος, nawʿ , species; 3. διαφορά, faṣl, difference; 4. ἴδιον, k̲h̲āṣṣa , property; 5. συμβεβηκός, ʿaraḍ , accident. The Ik̲h̲wān al-Ṣafāʾ add, in the tenth risāla , s̲h̲ak̲h̲ṣ , person). For the logicians, faṣl has two meanings: t…

ʿAmal

(2,071 words)

Author(s): Boer, Tj. de | Gardet, L. | Berque, J. | Ed.
(a.). 1. ʿAmal , performance, action, is usually discussed by the speculative theologians and philosophers only in connection with belief [see ʿilm, īmān] or with ʿilm and naẓar . From Hellenistic tradition was known the definition of philosophy as the "knowledge of the nature of things and the doing of good" (cf. Mafātīḥ , ed. van Vloten, 131 f.). Many Muslim thinkers have emphasised the necessity or at least the desirability of this combination (cf. Goldziher, Kitāb Maʿānī al-Nafs , 54*-60*). But it is the intellectualism of the Greek philosophy, in…
