[简答题]

The initial fund of general scientific knowledge is an invaluable asset (财产), but the young research worker should have no illusion(错觉) about how little it is compared with what he or she should acquire during succeeding years. As to the precise value of this initial fund of knowledge, this depends to a great degree on how it has been acquired and on who has been imparting(传授) it. 46)Young scientists cannot realize too soon that existing scientific knowledge is not nearly so complete, certain and unalterable as many textbooks seem to imply. The original papers of great scientists describing their discoveries and explaining their theories are never as rigid and self-confident as the resumes(摘要说明)of these discoveries and theories in textbooks by other men often suggest. Young scientists consulting these original works will find in them "it appears that", "it probably means", "it seems likely that", more than once, as expressions of elements of d

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
A. apparently useless information
B. the natural sciences
C. philosophy
D. technical applications
