QUOTE : If literature were nothing more than verbal algebra, anyone could produce any book by essaying variations. The lapidary formula 'Everything flows' abbreviates in two words the philosophy of Heraclitus: Raymond Lully would say that, with the first word given, it would be sufficient to essay the intransitive verbs to discover the second and obtain, thanks to methodical chance, that philosophy and many others. Here it is fitting to reply that the formula obtained by this process of elimination would lack all value and even meaning; for it to have some virtue we must conceive it in terms of Heraclitus, in terms of an experience of Heraclitus, even though 'Heraclitus is nothing more than the presumed subject of that experience. I have said that a book is a dialogue, a form of relationship; in a dialogue, an interlocutor is not the sum or average of what he says: he may not speak and still reveal that he is intelligent, he may emit intelligent observations and reveal his stupidity. The same happens with literature; d'Artagnan executes innumerable feats and Don Quixote is beaten and ridiculed, but one feels the valour of Don Quixote more.
