For all these lapses into polemical assertions, however, the historical analysis of Islam could be a useful if prolix introduction for the reader seeking to dispel unnecessary misconceptions. The trouble remains, nevertheless, that Küng’s favoured conclusions are always implicit in the teleology of his writing. Two-thirds of the way through these pages a section entitled ‘The Contemporaneity of Competing Paradigms’ begins, and with it Küng’s ideas about the grand emollient dialogue between the religions of Abraham. Opinions about this will divide along largely political lines. Despite Küng’s disavowal of any ‘utopianism’, however, the conclusion to which he points humanity is not very likely to derive from reasoned discussion but from the very process of secularisation which he advocates. The ‘moderate’ Islam being manufactured by liberals today, and by the British government and the elite of westernised Islamic believers whom they patronise, will eventually join with Christians and Jews who have also drained their religious understanding of traditional doctrinal content, and the result could well be something like Küng’s grand project, and which he calls ‘the transition to a post-modern and post-colonial polycentric paradigm’. To ensure this outcome he helpfully attaches (p. 642) a long special prayer of his own composition. The book itself ends with (an upbeat?) ascription: ‘No survival of our globe without a global ethic, a world ethic, supported by both the religious and the non-religious’. What more could you ask?

Küng threatens a new autobiography next, ‘giving an account of the second half of my life, in which I was exposed to powerful storms, but came through them to reach new shores and wide open spaces’. This study of Islam may perhaps be recognised as a kind of payment on account. You get quite a lot for your money: the table of contents, at the start of the book, itself runs to 15 pages. Never mind the quality; feel the width.
