"A thought is often original, though you have uttered it a hundred times." - Oliver Wendell Holmes

"When we read, another person thinks for us: we merely repeat his mental process... in reading, the work of thinking is, for the greater part, done for us. This is why we are consciously relieved when we turn to reading after being occupied with our own thoughts. But, in reading, our head is, however, really only the arena of some one else’s thoughts. And so it happens that the person who reads a great deal — that is to say, almost the whole day, and recreates himself by spending the intervals in thoughtless diversion, gradually loses the ability to think for himself; just as a man who is always riding at last forgets how to walk. Such, however, is the case with many men of learning: they have read themselves stupid...
The more one reads the fewer are the traces left of what one has read; the mind is like a tablet that has been written over and over. Hence it is impossible to reflect; and it is only by reflection that one can assimilate what one has read if one reads straight ahead without pondering over it later, what has been read does not take root, but is for the most part lost...
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...
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... 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...
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...
It would be a good thing to buy books if one could also buy the time to read them; but one usually confuses the purchase of books with the acquisition of their contents. To desire that a man should retain everything he has ever read, is the same as wishing him to retain in his stomach all that he has ever eaten... As the body assimilates what is homogeneous to it, so will a man retain what interests him...
The scientific, literary, and artistic spirit of the age is declared bankrupt about every thirty years. During that period the errors have increased to such an extent that they fall under the weight of their absurdity; while at the same time the opposition to them has become stronger. At this point there is a crash, which is followed by an error in the opposite direction"
