On the other hand, the speaker's assertion seems self-contradictory, for how can we know the limits of our knowledge until we've thoroughly tested those limits through exhaustive empirical observation——that is, by acquiring facts and information. For example, it would be tempting to concede that we can never understand the basic forces that govern all matter in the universe. Yet due to increasingly precise and extensive fact- finding efforts of scientists, we might now be within striking distance of understanding the key laws by which all physical matter behaves. Put another way, the speaker's assertion flies in the face of悍然不顾，公然违抗the scientific method, whose fundamental tenet is that we humans can truly know only that which we observe. Thus Francis Bacon, who first formulated the method, might assert that the speaker is fundamentally incorrect.
说实话，我觉得这一段里，作者玩了一个诡辩的小伎俩：先是指出原文观点的自相矛盾性，然后引出自己的看法——认识论远重要于获取新的事实和信息，也就是要“先认识知识和理解力的局限然后才是摄取新知。”
How can we reconcile our experience in everyday endeavors with the basic assumption underlying the scientific method? Perhaps the answer lies in a distinction between two types of knowledge——one which amounts to a mere collection of observations (i.e., facts and information), the other which is deeper and includes a realization of principles and truths underlying those observations. At this deeper level "knowledge" equals "under- standing": how we interpret, make sense of, and find meaning in the information we collect by way of observation
作者就上一段提出的问题推出自己的解决方法，即认识到“知识”分成两种：纯观察行为所得的信息;萃取之后的经过自己消化后的“理解”。但我觉得这里还有待发挥，估计是时间不够了，仓促间收笔吧。没有很好的说明白。
In the final analysis, evaluating the speaker's assertion requires that we define "knowledge,'which in turn requires that we address complex epistemological issues best left to philosophers and theologians. Yet perhaps this is the speaker's point: that we can never truly know either ourselves or the world, and that by recognizing this limitation we set ourselves free to accomplish what no amount of mere information could ever permit.
最后一句玩了复杂句的构句技巧，想搏ets一笑。但我觉得还是总结的不够好，没有说到点子上。其实，我们平实的写作大可不必如此玩弄文字，因为如果当别人都不知道你在说什么的话，一味专心于难句，无异于“喧宾夺主”了。个人认为，作者写得有点不知所云了
