On Reading and Books — an essay by German philosopher Arthur Schopenhauer (1788–1860), who influenced some of the most prominent minds in the world.
Ignorance is degrading only when it is found in company with riches. Want and penury restrain the poor man; his employment takes the place of knowledge and occupies his thoughts: while rich men who are ignorant live for their pleasure only, and resemble a beast; as may be seen daily. They are to be reproached also for not having used wealth and leisure for that which lends them their greatest value.
When we read, another person thinks for us: we merely repeat his mental process. It is the same as the pupil, in learning to write, following with his pen the lines that have been pencilled by the teacher. Accordingly, 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. … And just as one spoils the stomach by overfeeding and thereby impairs the whole body, so can one overload and choke the mind by giving it too much nourishment. For 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.
His argument is more nuanced than it might appear. For example, he offers:
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.
And he indirectly argues for the ‘Great books' …
It is because people will only read what is the newest instead of what is the best of all ages, that writers remain in the narrow circle of prevailing ideas, and that the age sinks deeper and deeper in its own mire.
And my favorite part of the essay:
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. He has been bodily nourished on what he has eaten, and mentally on what he has read, and through them become what he is. As the body assimilates what is homogeneous to it, so will a man retain what interests him; in other words, what coincides with his system of thought or suits his ends. Every one has aims, but very few have anything approaching a system of thought. This is why such people do not take an objective interest in anything, and why they learn nothing from what they read: they remember nothing about it.
And the best books, should be read twice:
Any kind of important book should immediately be read twice, partly because one grasps the matter in its entirety the second time, and only really understands the beginning when the end is known; and partly because in reading it the second time one’s temper and mood are different, so that one gets another impression; it may be that one sees the matter in another light.
