——〈在北京湖广会馆学界欢迎会的演说〉,1912年8月30日
Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.
Art is my escape and my prison.
【译文】国家强盛源于法治,衰弱混乱源于徇私。
The most perfect education, in my opinion, is such an exercise of the understanding as is best calculated to strengthen the body and form the heart.
