(a) If a book is forbidden, one may not read even the harmless parts of it, for there is the danger that, if one part is read, the other parts will also be read. But, if the part that occasioned the prohibition be removed, the prohibition ceases as regards the remainder of the book. (b) If a work is forbidden, one may not read any volume, if all the volumes deal with the same subject. But, if the volumes treat of different subjects or of one subject that is divisible (e.g., universal history), one may read such volumes as do not contain the danger that occasioned the prohibition. (c) If all the works of an author are condemned, the prohibition is understood to apply only to books (i.e., not to smaller works), and only to books dealing with religion, unless it appears that the other kinds of writings are also included; but the prohibition is to be presumed to include works that appear after the condemnation, unless the contrary is manifest. 861. Some outstanding works that have been condemned are the following: (a) In English: _Decline and Fall of The Roman Empire_ (Gibbons); _Myth, Ritual, and Religion_ (Andrew Lang); _History of England_ (Goldsmith); _The Roman Popes_ (Ranke); _The Life and Pontificate of Leo X_ (Roscoe); _Constitutional History of England_ (Hallam); _Political Economy_ (Mill); _Happiness in Hell_ (Mivart); _History of English Literature_ (Taine); _Reign of Charles V_ (Robertson); _Zoonomia_, or The Laws of Organic Life (Darwin). (b) In French: _Notre Dame de Paris_ (Hugo); _Life of Jesus_ and eighteen other works of Renan; all the works of Anatole France; _The Social Contract_ and four works of Rousseau; nearly all the works of Voltaire; _The Gospel and the Church, Gospel Studies, The Fourth Gospel, Apropos of a Little Book, The Religion of Israel_ (Loisy); all the works of Jean Paul Sartre; _La Deuxieme Sexe_ and _Les Mandarins_ by Simone de Beauvoir. 862. What is meant by “use” of forbidden writings? (a) In the first place, those “use” a writing who read it--that is, who go over it with their eyes, understanding the meaning therein contained. Hence, a person does not violate the church law against forbidden books if he merely listens to another read; although he might sin against the natural law, and even against the church law, if he induced the other to read to him; neither does a person violate the church law, if he merely glances at the characters, without understanding the sense expressed. Example: Titus, a professor of theology, has permission to read forbidden books, and he sometimes reads to his class doctrinal passages from works on the Index in order to explain and refute errors. Balbus examines very carefully the pages of a beautifully printed copy of a forbidden work, but he understands hardly a word of it, since it is in a foreign language. Neither Titus’ class nor Balbus are guilty of reading as forbidden by the Church, for strict interpretation is given to penal laws (see 485).
