Being reluctant to think , unwilling to study intensively and under-stand deeply and being complacent and satisfied at negligible knowledge all are the cause of poor intelligence, which can be germed as "foolish".
——Maxim Gorky, Russian writer
懒于思索、不愿意钻研和深入理解、自满和满足于微不足道的知识，都是智力贫乏的原因。这种贫乏通常用两个字来称呼，那就是“愚蠢”。
——俄国作家 高尔基 M
