So, why is Literature important? How does it show itself as indispensable to a culture? Here's what William Long has to say...
Importance of Literature
It is a curious and prevalent opinion that literature, like all art, is a mere play of imagination, pleasing enough, like a new novel, but without any serious or practical importance. Nothing could be farther from the truth. Literature preserves the ideals of a people; and ideals--love, faith, duty, friendship, freedom, reverence--are the part of human life most worthy of preservation. The Greeks were a marvelous people; yet of all their mighty works we cherish only a few ideals,--ideals of beauty in perishable stone, and ideals of truth in imperishable prose and poetry. It was simply the ideals of the Greeks and Hebrews and Romans, preserved in their literature, which made them what they were, and which determined their value to future generations. Our democracy, the boast of all English-speaking nations, is a dream; not the doubtful and sometimes disheartening spectacle presented in our legislative halls, but the lovely and immortal ideal of a free and equal manhood, preserved as a most precious heritage in every great literature from the Greeks to the Anglo-Saxons. All our arts, our sciences, even our inventions are founded squarely upon ideals; for under every invention is still the dream of Beowulf, that man may overcome the forces of nature; and the foundation of all our sciences and discoveries is the immortal dream that men "shall be as gods, knowing good and evil."
In a word, our whole civilization, our freedom, our progress, our homes, our religion, rest solidly upon ideals for their foundation. Nothing but an ideal ever endures upon earth. It is therefore impossible to overestimate the practical importance of literature, which preserves these ideals from fathers to sons, while men, cities, governments, civilizations, vanish from the face of the earth. It is only when we remember this that we appreciate the action of the devout Mussulman, who picks up and carefully preserves every scrap of paper on which words are written, because the scrap may perchance contain the name of Allah, and the ideal is too enormously important to be neglected or lost.
