明代夏寅说“君子有三惜 :此生不学 ,一可惜 ;此日闲过 ,二可惜 ;此身一败 ,三可惜。”首先是不学 ,不学无术者自然不会聪明 ,凡聪明的人总是孜孜不倦地学习。为写《资本论》 ,马克思多年坚持每天到大英博物馆读书 ,列宁一生总是手不释卷 ,不停地读书、写作 ,为丰富和发展马克? Xia Yin said Ming Dynasty, “Gentleman has three pity: life does not learn, a pity; idle day, two pity; this one defeat, three pity.” The first is not to learn, People always study tirelessly. For the purpose of writing The Capital Theory, Marx insisted on studying in the British Museum for many years every day. Lenin kept reading and writing all his life and kept enriching and developing the mark.
