This digest of a number of writings from the Idrisi tradition is a very welcome and necessary contribution to the deepening of our understanding of the intellectual history of Islam in the nineteenth century. It has grown out of an encounter of a kind that, alas, appears to happen too seldom in our compartmentalised universities: that of a renowned specialist of classical Sufism soundly trained in the German scholarly tradition with the latterday world of African historians which is still very much on the periphery of the majority of those involved in 'Oriental research'. 
Radtke demonstrates the importance of paying attention to the contents of the texts. This sounds more trivial than it really is; too often, scholars have simply spared themselves the trouble of trying to locate and then wade through the mass of writings produced by the subjects of their studies. Here, Radtke has done this for us. The result of his reading will certainly remain useful even after the bibliographical part of it is superseded by The Writings of Eastern Sudanic Africa  to which he himself is a contributor.
The influence that Ibn Idris, his students and 'grand-students' had across large parts of North and Northeast Africa, but also in peripheral regions of Arabia, Southeast Asia, or the Balkans, is too well known to be recapitulated here. Sufi brotherhoods in the Arab world and Africa have frequently become mass movements with widespread social and political influence, and it is this aspect that has attracted most of the attention of colonial politicians, historians, and anthropologists so far. The thought and teachings of the leading exponents of these Sufi movements have been studied to a much lesser degree. Radtke emphasizes that this lack of sound knowledge of the ideas behind the movements has seriously hampered much of the current discussion about the intellectual history of 18th and 19th century Islam and led to a number of questionable generalizations and clichés ('neo-Sufism', 'reformed Sufism' and 'Islamic Enlightenment' are not named directly, but clearly intended here).  To put the discussion on a sounder base, Radtke stresses the need of preliminary studies with detailed attention to the texts. The aim of his article is to contribute to establish the 'material' foundations necessary for a more general reflection by presenting a substantial body of writings that has remained 'almost unknown' to the scholarly community so far.
Radtke gives a digest of many larger and smaller works by Ibn Idris (1/2 p.), Muhammad 'Uthman al-Mirghani (5 pp.), other members of the Mirghani family and the Khatmiyya brotherhod (2 1/2 pp.), Isma'il al-Wali (14 pp.) and two of his sons (1/3 p.), plus a note on a work by Ahmad al-Salawi in praise of Isma'il which is preserved in Bergen. The distribution of pages is thus inverse to what one might have expected, the teacher receiving least, the 'grandstudent' most attention. It is therefore not a proportionally representative studyeven though Ibn Idris comes back in at the end where several beautiful passages by him on the universe, man, and the principles of mystical life (the Risalat al-qawa'id) are translated, along with two more technical notes by Isma'il (on the rules of entering the tariqa, dhikr, and khalwa).
The picture that emerges from this survey is, in Radtke's own words, 'that of a scholarly Sufism living within tradition and combining classical and post-classical elements' (p. 121). Continuity is perhaps what Radtke emphasises most (cf. his footnotes), refusing to recognize a purported break with tradition when the texts show so obvious parallels with earlier writings in content and style and liberally refer to authors such as Hakim Tirmidhi (Nawadir al-usul), Qushayri (al-Risala), Ghazali, Ibn al-'Arabi ('Anqa` mughrib, Bulghat al-ghawwas, al-Futuhat al-Makkiyya, Mawaqi' al-nujum), Ibn 'Ata` Allah (Hikam), Ibn al-Farid, 'Ala` ad-Dawla-i Simnani, Kubra (Fawa`ih), Jili (al-Insan al-kamil), Sha'rani, and finally, Mustafa al-Bakri. One of the most interesting of all the texts presented here is Mashariq shumus al-anwar, Isma'il al-Wali's major work, a long book describing his mystical worldview in terms that are at times reminiscent of Persian illuminationist thinking.
Among the subjects that are elaborated on in some detail in the digest are:
(a) in the Khatmi section: the different kinds of shaykhs (pp. 102-3); the two (p. 99) or elsewhere four (p. 104) meanings of khatm; introduction to the path for Sufi novices (p. 105 and passim);
(b) in the Isma'ili section: defense of a quietist political attitude (p. 106); 'history' of the Isma'iliyya (pp. 111-12); differences and rivalries between Isma'il and al-Mirghani (pp. 106-7, 110- 11 contain some very interesting indications of the problems Isma'il had in setting himself up as an independent shaykh); Isma'il's prayer of intercession (tawassul) and the cosmology that it comprises (p. 1079); everyone who sees the Propheteven after his deathis a Companion (sahabi) (p. 108, cf. p. 117); different classes and personal moulds of awliya` (pp. 109, 112-13, 116-17); different kinds of karamat (p. 114); the three kinds of khilafa (p. 115); the rules of khalwa (pp. 112, 119); the stages of spiritual development and their correspondence to cosmology (pp. 1169); different kinds of tajalli (p. 116).
The two main shortcomings of the present study are, in my opinion, due to Radtke's overly self-restrained approach. Ibn Idris may have been the subject of a recent monograph,  and his ideas mostly preserved only in student's notes (two reasons Radtke gives for dealing with him so summarily), but I certainly do not think that his chief works are better known than those of the other two protagonists. A more detailed presentation of the 'Iqd al-nafis, the Risalat al-radd, and the Kunuz al-jawahir would have been at least as welcome as the summaries given for Khatmi and Isma'ili works. Fortunately, Radtke and O'Fahey are preparing editions and translations of the latter two texts, which will help to fill in this lacuna. 
The other major desideratum remains a comparative analysis. 'The time for this seems not to have come yet', says Radtke (p. 94). However, a few more elaborate reflections on the ideas behind the texts, and some comparison with earlier writers, would have been useful and possible even on the basis of the present material alone; and Radtke's thorough knowledge of classical Sufism would appear to make him better suited for such an undertaking than most (for example, I would have appreciated a brief discussion of the term, fath, in the light of pp. 12930).
Equally important (but admittedly more difficult and more prone to gross misinterpretation) it would be to relate text to context, and to ask what possibly different meanings are given to the same old words when they are used in different contexts. This is the area of pitfalls in the current debate on 'neo-Sufism', and Radtke is probably right in calling for restraint here; but it is also, in the opinion of the reviewer, the area where an eventual solution is likely to emerge, and which therefore calls for imaginative suggestions. Linked to this complex is the question for whom these texts were primarily intended, and who actually read them. Radtke does not give a reason for his guess that Isma'il's 'theosophical and esoteric' Mashariq al-shumus was written for a broader public (p. 120). My own research rather suggests that such 'theoretical' literature was read only by the élite few, and that it was the sung poetry that exerted a much greater influence on the masses. Radtke stresses the need for a special study of this poetry (p. 98). One can only hope that this plea will be taken up soon.
A few minor points:
All this is in no way meant to diminish the value of Radtke's study; if we had only a dozen more of this kind for other contemporary traditions, our efforts at arriving at a sound intellectual history of 18th and 19th century Islam would be much facilitated. The reward earned by sweat and labour may point beyond scholarly literalism to a more human horizon, as is shown in this beautiful passage translated by Radtke (123) from Ibn Idris' al-'Iqd al-nafis (pp. 187-8):
The Prophet has two aspects [wijhatan, not wajhan]: One is turned towards God [...]. The other [...] is turned towards creation [...]. He is the reality of being, like a tree which has leaves, [twigs], branches, veins, roots, blossoms, and fruits; the reality of the whole, however, is the tree.Albrecht Hofheinz
