Spirituality Revolution by David Tacey, paints a detailed picture of 21st century spirituality especially, what Tacey calls, youth spirituality.
Good bit= Tacey's rereading of youth spirituality, particularly his concluding remarks about ecospirituality. Early in the book Tacey comments on the focus of young people on the immanent over the transcendent, whereas many modernists interpret this as something negative (materialism) Tacey argues it is something positive (environmentalism)- 'youth spirituality has become the conscience of the modern world. It studies environmental degradation, deforestation, salination, worldwide pollution, global warming, extinction of animal and plant species, loss of biodiversity, and asks, why is this happening.'- that is manifest in the spiritual realm as what he calls ecospirituality.
Bad bit= A few statements in the penultimate chapter which are challenges to the religious institution that I'm not sure about, eg 'I sometimes imagine that the so-called 'demise of religion' has been orchestrated by the spirit itself'. Two pages from the end Tacey also introduces the idea that young people are turning to technology to meet their need for community- 'The secular version of connectedness promises this: every man, woman or teenager with a mobile phone, Internet and email need never feel lonely again.'- An interesting point, and therefore a shame it was only mentioned two pages from the end.
A fine book nevertheless, approaching spirituality from a different perspective (psycho-analytical) to many books that are doing the rounds.
As mentioned previously, if you're interested the first chapter of Spirituality Revolution is viewable here.
