According to Herodotus, Xerxes wept at the sight of his army, which was too extensive for him to scan, at the thought that a hundred years hence not one of all these would be alive. Who would not weep at the thought in looking over a big catalogue that of all these books not one will be in existence in ten years’ time?Arthur Schopenhauer - "On Reading and Books"
It is the same in literature as in life. Wherever one goes one immediately comes upon the incorrigible mob of humanity. It exists everywhere in legions; crowding, soiling everything, like flies in summer. Hence the numberless bad books, those rank weeds of literature which extract nourishment from the corn and choke it.
They monopolise the time, money, and attention which really belong to good books and their noble aims; they are written merely with a view to making money or procuring places. They are not only useless, but they do positive harm. Nine-tenths of the whole of our present literature aims solely at taking a few shillings out of the public’s pocket, and to accomplish this, author, publisher, and reviewer have joined forces.
There is a more cunning and worse trick, albeit a profitable one. Littérateurs, hack-writers, and productive authors have succeeded, contrary to good taste and the true culture of the age, in bringing the world elegante into leading-strings, so that they have been taught to read a tempo and all the same thing — namely, the newest books order that they may have material for conversation in their social circles. Bad novels and similar productions from the pen of writers who were once famous, such as Spindler, Bulwer, Eugène Sue, and so on, serve this purpose. But what can be more miserable than the fate of a reading public of this kind, that feels always impelled to read the latest writings of extremely commonplace authors who write for money only, and therefore exist in numbers? And for the sake of this they merely know by name the works of the rare and superior writers, of all ages and countries.
Literary newspapers, since they print the daily smatterings of commonplace people, are especially a cunning means for robbing from the aesthetic public the time which should be devoted to the genuine productions of art for the furtherance of culture.
Hence, in regard to our subject, the art of not reading is highly important. This consists in not taking a book into one’s hand merely because it is interesting the great public at the time — such as political or religious pamphlets, novels, poetry, and the like, which make a noise and reach perhaps several editions in their first and last years of existence. Remember rather that the man who writes for fools always finds a large public: and only read for a limited and definite time exclusively the works of great minds, those who surpass other men of all times and countries, and whom the voice of fame points to as such. These alone really educate and instruct.
One can never read too little of bad, or too much of good books: bad books are intellectual poison; they destroy the mind.
In order to read what is good one must make it a condition never to read what is bad; for life is short, and both time and strength limited.
