Stewart Brand had a policy of not
wasting his reader's time on negative reviews in the Whole Earth
Catalogs or any of its progeny.
I learn from negative reviews and I hope you will. I loved Charles Taylor's previous books, Sources of the Self in which he does a great job of dealing with the question of individual authenticity.
But I'm furious with myself for spending $40 dollars on his current 775 page Secular Age. What we have is a Roman Catholic trying to find the roots of modernity in the dark ages.
Max
Weber correctly connected modernity and commerce to Protestantism.
Protestantism is about the power and validity of the individual outside
of social hierarchies in the search for worldly meaning.
Robert
Bellah tried to apply Weber's thesis to Japan and failed. Now Taylor
does the outrageous in trying to find the mental framework of
individualism and anti-hierarchy in 12th Century Roman Catholic monks
and scholars.
The Roman Catholic Church for
1500 years has stood for the status quo and it does to this day. 
At
the peak of its power the Church launched the Inquisition to murder
all deviation from the Church's catechism of status quo.
Of course it took 775 pages for Taylor to fail at his efforts to rewrite history. It would have taken him only 600 pages to show that the Catholic Church discovered the Copernican solar centric model, Darwin's evolutionary model and modern contraceptives.
I have an alternative approach to seeking the roots of modernity. Look at the societies that have most successfully adapted modernity and examine their commonalities. No Catholic or Muslim society would be on that list.
