Just for the record, here's a critic of mine - William Cavanaugh writing in response to an earlier piece by me that is, in turn, based on material in chapter 3 Freedom of Religion and the Secular State.
I'll be responding to Cavanaugh on the ABC site. Meanwhile, we can certainly quibble about how much blame we should allocate to religion for, say, the Thirty Years' War (for reasons that I sketch briefly in the book). But I should just say for now that the historical thesis Cavanaugh attributes to me is not one I have ever argued for. Perhaps something I have said somewhere as shorthand could be interpreted that way (I seem to recall some confusion during the IQ2 debate last year), but nothing like it appears in the first para of the piece that Cavanaugh objects to - and it's only in the first para that I touch on these issues about wars of religion.
What I say in the impugned essay and the book is not that the strife of the 17th century was resolved at the time by the introduction of secularist arrangements (a separation of church and state). It wasn't. Rather, I say that it provoked certain thoughts in the minds of political philosophers such as Hobbes and Locke, and that those thoughts are still of value to us today. I stand by that.
Anyway, I'll have a longer response elsewhere and will link to it when it's published.
