唐代的韩愈，强调不要埋没人才，在其《杂说》之中谈到“千里马常有，而伯乐不常有”，“世有伯乐，然后有千里马”，提醒人们，有了识才之士才会涌现出无数的人才。宋代黄庭坚在《过平舆怀李子先时在并州》诗中感叹：“世上岂无千里马，人中难得九方皋。”确实，人才如果遇不上“伯乐”，就会被埋没。要发现人才，贵在识才。关于这一点，古人的认识也颇有见地。三国的诸葛亮在其《便宜十六策•阴察》中论述：“洗不比江河，要之却垢；马不比骐骥，要之疾足。”就是说，洗涤不一定非要去大江大河，重要的是能够除掉污垢，马不一定非要骐骥，重要的是能够跑得快。而汉代司马迁在《史记•滑稽列传》中指出，挑选马匹，往往因为是瘦马就不予理睬，结果漏掉了良马；选拔人才，往往因为是贫士就看不起，结果失掉了贤人，“相马失之瘦，相士失之贫”。识别贤才，只有通过实践的检验，才能辨明。汉代徐干在《中论•修本》篇说：“路不险则无以知马之良，任不重则无以知人之德。”三国曹植《矫志诗》道：“道远知骥，世伪知贤。”这两段文字的中心论点是什么？采用了哪些论证方法？两段之间的层次关系如何？
