The History of the Siege of Lisbon

It is proven, therefore, that the proof-reader was mistaken, that if he was not mistaken then he was confused, that if he was not confused then he was imagining things, but let him who has never erred, been confused or imagined things, throw the first stone. To err, as the wise man said, is only human, which means that, unless we are wrong to take things literally, anyone who never errs cannot be a real man. Nevertheless, this supreme maxim cannot be used as a universal pretext to absolve all of us from lame judgments and warped opinions. He who does not know should have the humility to ask, and the proof-reader should always be mindful of this simple precaution, especially since he does not even need to leave the house or abandon his study where he is now working, for here he has all the reference books he needs to clarify matters, assuming he has been wise and prudent enough not to believe blindly in what he thinks he knows, because this rather than ignorance is the cause of the greatest blunders. On these crammed bookshelves, thousands and thousands of pages await a spark of awakening curiosity or that direct light which is nothing other than doubt in search of its own clarification. Let us then give credit to the proof-reader for having collected throughout his life so many different sources of information, although a mere glance reveals that the inventory does not include a computer, but his finances, alas, do not cover everything, and this profession, it should be said, is one of the worst paid in the world. One day, but Allah is greater, every proof-reader of books will have a computer at his disposal which he will connect umbilically, night and day, to the central databank, so that all he, or we, need worry about is that amongst these comprehensive data, no tempting error has crept in, like the devil invading a convent.
