On reading

Reading is not an end itself, but a means to an end.  Its chief purpose is to help towards filling in the framework which is made up of the talents and capabilities that each individual possesses.  Thus each one procures for himself the implements and materials necessary for the fulfilment of his calling in life, no matter whether this be elementary task of earning one's daily bread or a calling that responds to higher human aspirations.  Such is the first purpose of reading.  And the second purpose is to give a general knowledge of the world in which we live.  In both cases, however, the material which one has acquired through reading must not be stored up in the memory on a plan that corresponds to successive chapters of the book; but each little piece of knowledge thus gained must be treated as if it were a little stone to be inserted into a mosaic, sot hat it finds its proper place among all the other pieces and particles that help to form a general world-picture in the brain of the reader.  Otherwise only a confused jumble of chaotic notions will result from all this reading.  That jumble is not merely useless, but it also tends to make the unfortunate possessor of it conceited.  For he seriously considers himself a well-educated person and thinks that he understands something of life.  He believes that he has acquired knowledge, whereas the truth is that every increase in such 'knowledge' draws him more and more away from real life until he finally ends up in some sanatorium or takes to politics and becomes a parliamentary deputy.
