In the 1980s, Italo Calvino said in his essay "Why Read the Classics?" that "a classic is a book that has never finished saying what it has to say" and comes to the crux of personal choice in this matter when he says (italics in the original translation): "Your classic author is the one you cannot feel indifferent to, who helps you define yourself in relation to him, even in dispute with him."[Note 1] Consideration of what makes a literary work a classic is for Calvino ultimately a personal choice, and, constructing a universal definition of what constitutes a Classic Book seems to him to be an impossibility, since, as Calvino says "There is nothing for it but for all of us to invent our own ideal libraries of classics."
What actually makes a work of literature a "classic book" is not just a consideration of extensively published authors. In 1920, Fannie M. Clark, a teacher at the Rozelle School in East Cleveland, Ohio, predates Calvino's similar conclusions by 60 years when she also essayed the question of what makes a book a "classic" in her article "Teaching Children to Choose" in The English Journal.
Over the course of her essay, Clark considers the question of what makes a piece of literature a classic and why the idea of "the classics" is important to society as a whole. Clark says that "teachers of English have been so long trained in the 'classics' that these 'classics' have become to them very much like the Bible, for the safety of which the rise of modern science causes such unnecessary fears." She goes on to say that among the sources she consulted was a group of eighth-graders when she asked them the question: "What do you understand by the classics in literature?" Two of the answers Clark received were "Classics are books your fathers give you and you keep them to give to your children" and "Classics are those great pieces of literature considered worthy to be studied in English classes of high school or college". Calvino agrees with the Ohio educator when he states "Schools and universities ought to help us understand that no book that talks about a book says more than the book in question, but instead they do their level best to make us think the opposite." Clark and Calvino come to a similar conclusion that when a literary work is analyzed for what makes it 'classic', that in just the act of analysis or as Clark says "the anatomical dissection", the reader can end up destroying the unique pleasure that mere enjoyment a work of literature can hold.
While blogging on the website guardian.co.uk in 2009, Chris Cox echoes Twain's "classic" sentiments of 1900 and Bennett's witticism about classic books when he opined on the Guardian.Co "Books Blog" that there are actually two kinds of "classic novels":
The first are those we know we should have read, but probably have not. These are generally the books that make us burn with shame when they come up in conversation... The second kind, meanwhile, are those books that we've read five times, can quote from on any occasion, and annoyingly push on to other people with the words: "You have to read this. It's a classic."
Charles Augustin Sainte-Beuve
In 1850, Charles Augustin Sainte-Beuve (1804–1869) stated his answer to the question "What is a Classic?" ("Qu'est-ce qu'un classique?"): The idea of a classic implies something that has continuance and consistence, and which produces unity and tradition, fashions and transmits itself, and endures…. A true classic, as I should like to hear it defined, is an author who has enriched the human mind, increased its treasure, and caused it to advance a step; who has discovered some moral and not equivocal truth, or revealed some eternal passion in that heart where all seemed known and discovered; who has expressed his thought, observation, or invention, in no matter what form, only provided it be broad and great, refined and sensible, sane and beautiful in itself; who has spoken to all in his own peculiar style, a style which is found to be also that of the whole world, a style new without neologism, new and old, easily contemporary with all time.
In this same essay, Sainte-Beuve quoted Goethe (referring to the 'classics' concept): "Ancient works are classical not because they are old, but because they are powerful, fresh, and healthy."[Note 2]
The concept of 'the classic' was a theme of T.S. Eliot's literary criticism as well. In The Sacred Wood he thought that one of the reasons "Dante is a classic, and Blake only a poet of genius was "because of "the concentration resulting from a framework of mythology and theology and philosophy". (In commenting about Eliot's influence, Professor Jan Gorak stated that "the idea of a canon has become intertwined with the idea of the classic, an idea that T.S. Eliot tried to revitalize for the 'modern experiment'".) In echoes of Sainte-Beuve, Eliot gave a speech to the Virgil Society concerning himself with the very same question of "What is a Classic?" In his opinion, there was only one author who was 'classic': "No modern language can hope to produce a classic, in the sense I have called Virgil a classic. Our classic, the classic of all Europe, is Virgil." In this instance, though, Eliot said that the word had different meanings in different surroundings and that his concern was with "one meaning in one context". He states his focus is to define only "one kind of art" and that it does not have to be "better...than another kind". His opening paragraph makes a clear distinction between his particular meaning of classic having Virgil as the classic of all literature and the alternate meaning of classic as "a standard author".
Literary figures from different eras have also weighed in (sometimes humorously) on the matter. Alan Bennett, the modern English playwright and author, said that "Definition of a classic: a book everyone is assumed to have read and often thinks they have read themselves." Mark Van Doren, the Columbia University professor and poet, is quoted by Jim Trelease (in his library-monograph Classic Picture Books All Children Should Experience), as saying that "A classic is any book that stays in print". And in his "Disappearance of Literature" speech given over a century ago in 1900, Mark Twain said, (referring to a learned academic's lofty opinion of Milton's "Paradise Lost") that the work met the Professor's definition of a classic as "something that everybody wants to have read and nobody wants to read".
Classics are often defined in terms of their lasting freshness. Clifton Fadiman thought that the works that become classic books have their start in childhood, saying that "If you wish to live long in the memory of men, you should not write for them at all. You should write what their children will enjoy." In his view, the works we now judge to be classics are "great starters". Fadiman unites classic books through the ages in a continuum (and concurs with Goethe's thoughts on the vigor and relevance of the ancient Classics), when he states that classic books share a "quality of beginningness" with the legendary writer of the Iliad and the Odyssey – Homer himself. Ezra Pound in his own tome on reading, ABC of Reading, gave his opinion when he stated, "A classic is classic not because it conforms to certain structural rule, or fits certain definitions (of which its author had quite probably never heard). It is classic because of a certain eternal and irrepressible freshness." Michael Dirda, the 1993 Pulitzer Prize winning critic, concurred with Pound's view regarding the vitality of a classic when he wrote that "...one of the true elements of a classic" was that "they can be read again and again with ever-deepening pleasure."
