226"People are mistaken when they assume that the problems they confront are more complex and challenging than the problems faced by their predecessors. This illusion is eventually dispelled with increased knowledge and experience."

Disagree
The author neglects what's "complexity"meanning in this issue. Actually, "Complexity" has two meanings of obsolute dissimilarities when applied to different criterions imposed on defination.

if we relate the levels of complexity to the efforts we used when soloviing the problems, it's more like that the problems faced by our preceders are of more difficulties in that the established and proved-right principles are comparatively less than those of todays. They have to firstly observe certain phenomena for a long period of time, and then calculate data concluded throught these phenomena, before reaching a law of scinece that is necessary in solving problems whereafter. For example, Newton dedicated a great sum of painstaking efforts in deducing three classical physics theories, it took yearlong time for Zu Chongzhi to work out pi, Archimedes educed buoyancy law at the expense of his large amount of time. on the contray, even a junior school studetns now find it a piece of cake to work out circle's perimeter using pi, This is also true when comes to Physics and other fields of study. In these cases, the problems they encountered are far beyond what we can imagine even people now take their establishe laws for grounded and think them simple. So, in terms of efforts consumption, the problems encountered by people at remote antiquity are more difficile and chanllengiing.

In context of knowledge development, the problems nowadays are inevitablly more complicated and challengiing becaue they would involve more techoloques, deeper understadning of things, more complete perspective towards circumstances, more profound expertises and the like, Take geography for instance, people in old times may only have to study the relationship between people and moon and earth, however, now, with the advancement of understanding of solar system, people still have to ponder at how univer come into beiing.
229"The best way to learn a new subject or skill is to study small segments or details in great depth rather than to start by trying to develop a sense of the whole."
(今天就贴自己写的上来了)
position: in terms of pursuing knowledge, developing a sense of the whole of a given subject is the premise for futher and deeper study in detail,
A, obtainning holistic understanding of the subject enables us to knwo what actually the subject is and what branches is it concerned about. In thsi case, as a matter of fact, we can narrow down our research to a feasible and impactful scoupe which inevitabley saves our time and energy. For instance, having been clearly informed through unitary investigation of a potential project that a philosophic research is concerned with ideologies put forward by Plato and Scrates, we then can purposefuly read books about the two pilosophers instead of all. In this sense, integrited study is benefic in that it narrows our topics to a specific range
2, In contrast, focusing on detailed knowleges may sometiems mis advise our thought to a totally adverse direction which is detrimental for our study, For example, if the aim of a astronomy is to validate the positive effects of heliocentric theories of planetary motion put forward by Nicolas Copernicus, However, a researcher,without knowing the purpose of the research, firstly and intensively began to dig into the theory's indeterminism that Einstein was displeased by. he will inextricably only be leaded to a 180-degree differnent result of the purpose of this research, that is, the nagaive effect of heliocentric theory.

Having viewd all the aspects above, it's sagacious to conduct a holistic study rather than small segmetns in great depth
