왜 책을 읽어야 할까?
1년에 책 한 권 안 읽는 사람이
성인 10명 중 6명이라고 한다. 정보가
흘러넘치는 디지털 시대에 책을 읽어야 하는
이유는 뭘까? 독서를 해야 하는 이유는 제대로
읽고 판단하는 능력, 즉 문해력 때문이다. 문해력은
그저 글을 읽거나 단어의 의미를 아는 것을
뜻하지 않는다. 다양한 맥락으로 연결된
자료를 통해 정보를 발굴하고 이해하고
새롭게 해석하여 소통까지 이르는
능력을 뜻한다.


- 김을호의 《결국 독서력이다》 중에서 -


* 문해력은 실력입니다.
세상을 헤쳐가는 막강한 무기입니다.
문해력의 출발은 독서입니다. 그러나 단지 책을 읽고
해독하는 것에만 국한되지 않습니다. 우리는 서로 대화를
하면서도 소통의 부재를 느낍니다. 상대가 무슨 말을 하는지
제대로 이해하지 못하는 사람들이 늘어갑니다. 왜일까요?
문해력, 청해력의 부족 때문입니다. 문해력은 단숨에
늘어나지 않습니다. 어릴 적부터 훈련이 되어야
가능합니다. 그래서 독서가 필요합니다.

고통스러운 일상이라도
늘 고통스럽지만은 않다.
점심까지만 해도 뭐라도 올 것처럼
잔뜩 찌푸렸던 하늘이 언제 그랬냐는 듯
청명하게 갠 오후를 보여 주기도 하지 않은가?
작은 블라인드 틈 사이로 강렬한 햇빛이 파고들더니
그대로 책상 앞까지 가득한 걸 보면
감동 그 자체 아닌가?


- 김범준의 《지옥에 다녀온 단테》 중에서 -


* 모든 것은 양면을 가집니다.
고통이 있기에 영광이 있고, 영광에 탐닉하다
천 길 추락을 경험합니다. 어둠은 빛을, 빛은 어둠을
낳습니다. 모든 것은 가장 알맞은 때에, 알맞은
모습으로 드러납니다. 어려운 국면에서 길이
보이지 않는다면 기다림으로 희망을 갖고,
너무 잘나가는 듯하면 절제와 겸손으로
몸을 낮추어야 합니다.
