John Daly, in his highly recommended book, Michael Davies, An Evaluation, has great quotes from Orestes Brownson and Fr. Felix Sarda y Salvany (footnote 20), on driving away that bugbear of a false understanding of private judgment, and what erroneous private judgment truly is.
See the attachments. The second attachment completes the footnote quote from the previous page.
I think Daly's book is available in pdf on the Novus Ordo Watch website. That was how I got it.
