No matter how many books you keep reading,
and cram and accumulate vast amounts of knowledge just because it's written in the book,
reading is not your own brain, but merely tracing the thoughts of others,
and you are not thinking with your own brain at all,
but merely a collection of fragments of other people's thoughts.
Rather, you lose the ability to think for yourself,
and even though you think you've studied, you end up becoming stupid.
本に書かれてあるのだからと、いくら本を読み続けて、
膨大な知識を詰め込み蓄積し過ぎても、
読書は自分の頭ではなく、単に他人の思索をなぞったに過ぎず、
自分自身の頭では全く何ら思索することがなく、
他人が考えた思索の断片、寄せ集めに過ぎない。
むしろ自分の頭でものを考える力が奪われて行き、
勉強したつもりが、馬鹿になるのだ。
