In a word, astounding.
In meticulous detail, and with a frightening grasp of arcane rituals in ancient texts and modern practice, Lagerway demonstrates how "China" was Daoist not Confucian. The mysterious powers of order and chaos, gods and ghosts, historical and mythical imagination, ritual activity and ritual architecture and ritual expenditure, local festivals and imperial patronage... the whole whack, assimilating, taming and incorporating all manner of Buddhist ideas (when the anti-Buddhist campaigns of chapel and shrine destruction, forcible laicisation of monks and nuns and book-burnings that kicked off in 445, 714 and 840 proved unsustainable or undesirable), building on, critiquing and supplanting countless local shamans, exorcists and witches across the land (as far as was possible, over millennia, often with the violent suppressive collusion of government), and the ongoing invention, re-invention and embrace of Daoist revelations old and new and the canonization and embrace of many semi-divine figures into the pantheon....
All of this vastly overshadowed the cult of the ancestors (forbidden to the common people according to the Book of Rites, and not opened up to them until almost two thousand years had passed) and the rationalism of the Confucian elite. Why has everyone been so mistaken about this for so long? Well, the neo-Confucians of the Song dynasty finally began to get their way in the Ming dynasty with the help of foreign friends... "When the Jesuits arrived on the Chinese scene with their own Thomist baggage, they were not arriving and on virgin territory but in a space where the time of the neo-Confucian orthodoxy had come. The Chinese elite had not yet driven all gods from the space we call China -- for that they would have to wait for their twentieth century descendants, the Nationalists and then the Communists -- but they were making good progress. To make a long story short, Thomist rationalism encountered neo-Confucian rationalism and found every reason to make a deal for their respective agendas..." (p.4) Thus European observers constructng one sort of modernity and painting one sort of "China" were pleased to find such sensible civil fellows as these nonreligious Confucians (the teeming, multitudinous realities of the Daoist-Buddhist-popular synthesis could be dismissed as 'superstition', and even the blood sacrifices of state religious Confucianism could be overlooked) who were shoring up their own nominalist and elitist image of ritual China and their grip on central power.
This is not to say that Confucianism was not important, but that alongside the "lineage village" conception was a Daoist "territorial village" conception (expressed and re-expressed over centuries in all manner of rituals, temples, geomancy and imaginative literature), and this extended right up to empire level. "Continent of the gods" (神州) is an ancient name for China that owes nothing to Confucius, and everything to the authorising power of a ruler over gods in relation to space and supernatural fears and hopes.
There is so much more to say about this insanely brilliant book, not least in the graciousness of its author who frequently notes how recent works have corrected or greatly improved his own earlier seminal contributions to the field. Might return to some of the gems later...
