阅读下列史料并回答问题：
材料一
宋高宗在致金兵元帅信中说：“古之有国家迫于危亡者，不过守与奔而已。今以守无人，以奔则无地，所以諰諰然惟冀阁下之见哀而赦已，前者连奉书，愿削去旧号，是天地之间，皆大金之国．而尊无二上，亦何必劳师远涉而后为快哉!”
——《建炎以来系年要录》卷26
材料二
宋高宗对大臣说：“朕兼爱南北之民，屈已讲和非怯于用兵也。若敌国交恶，天下受弊，朕实念之。今通好休兵其利博矣。士大夫狃于偏见，以讲和为弱，以用兵为强，非通论也。”
——《建炎以来系年要录》卷114
请回答：

在上述材料反映的政策的指导下，产生了什么样的后果

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 or theoretical knowledge, sought only for the purpose of understanding, in order to fulfill the need to understand that is intrinsic and con-substantial to man. What distinguishes man from animals 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, man 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 for the most 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 section 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 men to study the 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. Butt in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.

A. literature

B.chemistry
