The book actually calls out the liberal humanist ideology as an ideology. Discusses the benefits (greater collaborative opportunities) and the drawbacks (loss of ideological meaning)
I think it’s an excellent exploration of the ideology common in western secular society. Even if you oppose that ideology I highly recommend that you understand it.
Right but from the summary I feel it seems like a history told from that lens. Just like a different lens causes one to see "the history of society is the history of class struggles".
