 The neo-ultramontanes wanted to pass by decree the most extreme definition of papal infallibility possible and did not wish for debates at all.They were, indeed, regarded as imprudent by more moderate ultramontanists who won the debate at the First Vatican Council.Neo-ultramontanism as a movement dates back to the writings of Joseph de Maistre, who in "Du Pape" ("about the Pope"), argued essentially that what the Pope says is true to the exclusion of all other contrary truths.
