“所谓正常其实是最罕见的。正常其实是一种理想。是人们根据人性的共性编排出来一幅画。要想把这些人类共性在一个人身上找到实在太难了。”“完全正常的人是一个幻象。他要拥有所有的正常指数。”

毛姆 《毛姆写作回忆录》 （又译《总结：毛姆写作生活回忆》），中文版第65-66页。

英文原文：The normal is what you find but rarely. The normal is an ideal. It is a picture that one fabricates of the average characteristics of men, and to find them all in a single man is hardly to be expected.
