Timothy Wilson’s translation of excerpts from Cardinal Zigliara’s Summa philosophica continues at The Josias. Today: the error of “liberty of teaching.” While perhaps not as pressing as the question of toleration of non-Christian cults, this is still an important question. The Cardinal’s analysis begins:
Question. Simultaneously one with liberty of conscience and of cult, there is proclaimed by the more recent liberalism a liberty of teaching, particularly with respect to the means with which it is principally exercised, namely, with respect to liberty of the press (la libertá della stampa). We ask, therefore, whether this liberty is upright, and to be approved by the civil authority. Here again I caution that the discussion is concerned, not with tolerance, but with approbation: evils indeed are able to be tolerated, yet naught but goods ought to be approved.
(Emphasis in original.) You should read the whole thing at The Josias.
For our part, we note that the question of the rights of error seems to be more, not less, important with each passing day.
