For me, scientific knowledge is divided into mathematical sciences, natural sciences or sciences dealing with the natural world (physical and biological sciences), and sciences dealing with mankind (psychology, sociology, all the sciences of cultural achievements, every kind of historical knowledge). Apart from these sciences is philosophy, about which we will talk later. In the first place, all this is pure of theoretical knowledge, sought only for the purpose of understanding, in order to fulfil the need to understand what is intrinsic and consubstantial to man. What distinguishes man from animal is that he knows and needs to know. If man did not know that the world existed, and that the world was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn’t be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance because they also contribute to defining him as man and permit him to pursue a life increasingly more truly human.

But even while enjoying the results of technical progress, he must defend the primacy and autonomy of pure knowledge. Knowledge sought directly for its practical applications will have immediate and foreseeable success, but not the kind of important result whose revolutionary scope is in large part unforeseen, except by the imagination of the Utopians. Let me recall a well-known example. If the Greek mathematicians had not applied themselves to the investigation of conic sections, zealously and without the least suspicion that it might someday be useful, it would not have been possible centuries later to navigate far from shore. The first man to study nature of electricity could not imagine that’ their experiments, carried on because of mere intellectual curiosity, would eventually lead to modern electrical technology, without which we can scarcely conceive of contemporary life. Pure knowledge is valuable for its own sake, because the human spirit cannot resign itself to ignorance. But, in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.

阅读下列材料，回答后面的问题。

成都市中小学正掀起“国学经典诵读活动”的高潮，不少学校正大力开展国学经典诵读活动，让孩子们与经典相伴。

　　材料一：某小学在校园文化环境的营造中，充分利用书香长廊、橱窗、墙壁、黑板报等空间，以多种艺术表现形式，渗透国学经典的文化元素，让孩子在耳濡目染中快乐成长。

　　材料二：某学校提倡快乐学国学。校园内众多的楹联、教学楼墙上的《弟子规》、经典美文以及出自经典的指路牌（“三乐苑”“积步轩”）等，都让学生随时能接触到经典。

　　材料三：某中学让古诗文、名言警句上墙、上板报。只要走进校园，就可以看到孔子、孟子、老子等圣贤的经典名句把各个角落的橱窗装点一新，可以看到同学们以国学经典为内容的书法展，可以看到以国学经典为主题的板报，处处显现出同学们与传统文化的亲近。
