当我们描述存在于过去或存在于现在的人类社会时,我们就必不可免地要使用数字和数量,年龄、出生时间、财产、妻子有几个、孩子有多少。我们这样做,又自然会把有相同行为或相同思想的人分成各个集团。我们用下述术语如“中产阶级”、“法国人”、“保守派”,就是为了描述这样的集团。我们必须这样分门别类才行,因为只有通过这样的办法,我们才能够处理各种各样人类的思想和行为。 When we describe the human society that exists in the past or existing in the present, we must inevitably use numbers and numbers, age, time of birth, property, a few wives and children. When we do this, we will naturally divide people with the same behavior or the same ideas into groups. We use the following terms such as “middle class”, “French”, “conservatives” to describe such groups. We must be divided into different categories, because only through this approach can we handle all kinds of human thoughts and actions.
