Good list. I would add that many priessts were gullible and/or naive, in part because they were products of a narrow seminary education which taught them the bad things about other points of views but not the good things than be so seductive. Take psychology,for instance. It pretends to be science when it is is only quasi-science. One cannot dismiss it ought of hand, One must deal with its truths, the half-truths as well as the falsehoods. Then there was the cult of Teilhard, whom Maritain despised but about whom even the Holy Father has some good things to say because the Jebbie had some good things to offer. The worst offenders, I think, are always the idealists because
so many are going to be disillusioned, but not before they mess things up for the people they influence.
That is a truly excellent point. There were some who, as you say, were well meaning but they simply didn't know how to defend their point of view. They had had such a cautious, timid education that when push came to shove, even though they were fundamentally orthodox, they had no idea how to express it, defend it, or even what it really meant. And half-truths are almost more convincing than real truths, because they can be combined so easily with other convenient half-truths...
