保持对经验生活的现实关切,注重“工具合理性”的实用研究,尊重现代科学理性的方法论态度,坚守自由平等的现代民主社会信念和追求自由个人的价值理想,是“哈佛哲学”中最基本的哲学理念,也是对“美国精神”长期产生主导性影响的缘由. It is the most basic of the philosophy of Harvard to keep practical concerns about experience and life, pay attention to the practical research of “tool rationality”, respect the methodological attitude of modern scientific rationality, uphold the belief of free and fair modern democratic society and the value ideal of free individual. Philosophy is also the reason for the long-term dominant influence on the “American spirit.”
