2. 技术的目标：
30. "The primary goal of technological advancement should be to increase people's efficiency so that everyone has more leisure time."
176 "The function of science is to reassure; the purpose of art is to upset. Therein lies the value of each."
3. 其它：
31."Money spent on research is almost always a good investment, even when the results of that research are controversial."
186 "Practicality is now our great idol, which all powers and talents must serve. Anything that is not obviously practical has little value in today's world."
1. 诚然，在这个物质社会中，我们追求实用性是自然而然的事情，毕竟人类的生存于发展是需要物品的实用性来支撑的。比如，我们的每天的衣食住行。特别是在科学技术方面，许多发明创造都是收到实用性的驱使。比如人们想要进行大规模计算，计算机应运而生;人们想提高交通速度，飞机也因此而诞生，人们要与世界交流，互联网也随之产生。从这一点上看，实用主义是人们生存发展的必然趋势。
2. 然而，我们要注意到在人类的文明进程中，实用主义并不是唯一的主题。人类对于宗教，信仰，理想，艺术的追求同样推动了人类历史的发展。比如华盛顿，甘地，马丁路德金等人为自由而奋斗。
3. 必须承认，一些看似没有实用性的东西，如人类探索外太空，但是从长远来看，这是对人类有巨大意义的。是我们制造有实用性东西的理论基础，比如数学，比如物理(physics)，如果没有这两个理论的话，那么就不可能发明电脑。比如文学literature，绘画，音乐它们虽然没有什么实用价值，但是它们丰富了我们的生活。我们对太空的探索，对人类长远发展来讲都有好处。
129. "Technology is a necessary but not always a positive force in modern life."
115. "It is through the use of logic and of precise, careful measurement that we become aware of our progress. Without such tools, we have no reference points to indicate how far we have advanced or retreated."
9. "Academic disciplines have become so specialized in recent years that scholars' ideas reach only a narrow audience. Until scholars can reach a wider audience, their ideas will have little use."
