【原文】
子曰：“知之者不如好之者，好之者不如乐之者。”
【译文】
孔子说：“懂得它的人，不如爱好它的人；爱好它的人，又不如以它为乐的人。”
【评析】
孔子这句话为我们揭示了一个怎样才能取得好的学习效果的秘密，那就是对学习的热爱。不同的人在同样的学习环境下学习效果不一样，自身的素质固然是一个方面，更加重要的还在于学习者对学习内容的态度或感觉。正所谓“兴趣是最好的老师”，当你对一门科目产生了兴趣之后，自然会学得比别人好。
《论语》中的“知之者不如好之者，好之者不如乐之者”句，主要讲学习的三个层次，以知之者突出好之者，再紧承好之者突出乐之者。这就如同数学中的逻辑推导，层层推进，使说理更加透彻，令人信服。
