13、怀疑精神是做一切学问的基本条件。,论述求知需有怀疑精神，不应盲从迷信。,得出结论,指出做学问要有怀疑精神的依据。,譬如在国难危急的时候，各地一定有许多口头的消息，说得如何凶险，那便是别人的传说，不一定可靠；要知道实际的情形，只有靠自己亲身视察。,举例论证：论证“别人的传说，不一定可靠”，引出下文对做学问需要怀疑精神的论述。,做学问也是这样，最要紧最可靠的材料是自己亲见的事实根据；但这种证据有时候不能亲自 看到，便只能靠别人的传说了。,类比论证：表明“做学问”时，面对传言也应靠自己亲自去视察才可辨真伪一样，说理通俗易懂。,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状

16、问：这是谁说的话？最先见于何书？所见的书是何时何人著的？著者何以知道？我们若能这样追问，一切虚妄的学说便不攻自破了。,举例论证：举例说明对于传说要善于思考质疑，强调怀疑精神对做学问的重要性。,论述求知需有怀疑精神，不应盲从迷信。,经过“怀疑”“思索”“辨别”三步以后，那本书才是自己的书。那种学问才是自己的学问。否则便是盲从，便是迷信。,反面论证：从反面论述“怀疑”“思索”“辨别”的必要性。,“怀疑”“思索”“辨别”三步的顺序能否调换？为什么？,不能。因为人只有先怀疑才可能思索，只有思索才可能辨别是非，三个步骤是按人对事物进行辨析时思维的先后顺序排列的，调整后就不符合人的认知规律了。,状元成才路

25、后之学者都墨守前人的旧说，那就没有新问题，没有新发明，一切学术停滞，人类的文化也就不会进步了。,反面论证：指出后之学者都墨守前人的旧说，即毫无怀疑精神的危害，从反面论证怀疑精神的重要作用。,1.结构清晰，逻辑性强。,文章开头两段引用我国古代两位著名学者的话，提出中心论点。第35段先从消极方面作论证，第3、4段先指学问的基础是事实和论据，再论述对有时只能是传说的论据要有怀疑精神，对传说都应当经过一番思考。第5段扩展开去，提出“不论对哪一本书，哪一种学问，都要经过自己的怀疑、思索与辨别，不可盲从迷信”。第6段首句中的两个分句分别概括了上下文的两个分论点。由此可见，本文层层深入，对怀疑的精神在做学问
26、过程中的必要性和意义，作了全面而精当的阐述，层次分明，思路清晰。,2.多种论证方法，说理有力。,首先，本文使用了道理论证，引用古代著名学者的话作为论据，增强了文章的说服力。如第5段中引用孟子的话“尽信书则不如无书”，有力地证明了段首提出的论点。此处，本文还使用了举例论证。为了论证对传说必须有怀疑精神这个论点，第4段举了古书上“三皇、五帝”和“腐草为萤”两个例子，使人确信古书记载的传说不一定可靠，怀疑确有必要。第六段为了论证怀疑是建设新学说、启迪新发明的基本条件，又举清代大学问家戴震读书善疑的事例为证，极具说服力。,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才

29、必要步骤,怀疑是建设新学说、启迪新发明的基本条件,做学问要有怀疑精神,三皇五帝,人们一般以“三皇五帝”泛指远古时代的帝王，但对三皇五帝的具体解释，史籍的记载各不相同，一般认为：“三皇”是指燧人氏、伏羲氏、神农氏(见礼纬含文嘉)。传说三皇分别掌管着天、地、人。燧人氏发明了钻木取火，火象征着太阳，人们便尊其为天皇；伏羲氏教会了人们“结绳为网以渔”，造福于民，主要在人间活动，人们便尊称他为地皇；神农是农业之神，教民耕种，采撷庄稼，还尝百草，创医学，便被尊称为人皇。,“五帝”是指黄帝、颛顼、帝喾、唐尧、虞舜(见史记五帝本纪)。他们都是传说中太古时代的几个君主。 传说，黄帝是中华民族的始祖，居轩辕之丘，
30、故号轩辕氏(亦称有熊氏)，他是50006000年前北方氏族部落的首领，先后战胜了东方夷人的首领蚩尤、西方羌人的首领炎帝，被四方首领公推为“天子”，统一了天下，促进了各族人民的大融合，逐渐形成了古老的华夏族，也就是汉族的前身，他是当之无愧的“人文始祖”。 颛顼，黄帝之孙。他继承了黄帝的统治权，是当时颇为,强大的部落首领。 帝喾，黄帝的曾孙，在位70多年，政绩突出，颇得民望。 唐尧，帝喾的儿子、黄帝的五世孙。他当上部落首领后，能够与老百姓同甘共苦，所以，老百姓非常拥戴他。 虞舜，颛顼的七世孙，传说他是通过尧“禅让”上位的。尧在位70年后，因年纪大了，就召开部落联盟会议，讨论继承人的问题，大家都推举
31、虞舜，反映他有德有才，比较合适。虞舜上台后，果然不负众望，亲自耕猎，很受人们爱戴。,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,状元成才路,
