I've read and re-read Rabbi Nathan Lopes Cardozo's pair of essays on The Art of Bold Ideas (part 1 and part 2), but I must admit that the author's thinking is beyond me.
1. It seems to me that the author inappropriately conflates a range of frustrations (intellectual laziness, foolish certitude, addiction to information as opposed to knowledge, religious defensiveness, poor teaching, etc) under one heading (lack of bold ideas).
2. In writing off the many foibles of our generation as a "lack of bold ideas", R' Cardozo not only does his many causes a disservice, but he also ignores reality.
Sectors within 'Orthodoxy' of the past two generations have seen several major changes; some of these have affected only some of Orthodoxy, and some of them have affected the whole:
* An embrace of the State of Israel and Zionism on practical and philosophical levels
* Social engagement with secular Jewry - a marked change from much of European Orthodox culture in the 19th century
* Acceptance of a liberal arts education in Orthodox circles
* Political engagement with the non-Jewish world on a level not seen for many centuries
* Development of women's religious education and secular education, including the achievement of advanced certification in both areas
* Shift of the center of halachic authority from Europe to North America to Israel
* Funding of Orthodox institutions by non-Orthodox Jewish institutions
* Translation of Torah - both verbal translation and philosophical translation - to appeal to the masses
And more; this is just a quick list.
In fact, it might be argued that we need a generation of consolidation, for that which changes too quickly loses its center of gravity. This would no doubt frustrate those who champion change and call for revolution, but it may be a necessity nonetheless.
