象路易斯·亨利·摩尔根那样能对二十世纪有着巨大影响的十九世纪社会思想家,为数无几。所有知名的社会学者都至少通过两种途径对他们的社会发生影响:一种是直接的,是从他们对社会科学或哲学作出的贡献而产生的;另一种是隐蔽的,它相机改换整个文化对世界和社会的观点。可将这两种影响看作是科学战线和第五纵队。要分清一位学者是真正的科学家还是第五纵队的队员,首先要在摩尔根身上分清这一点,并和其他学者进行比较,是最为重要的。 There are only a handful of nineteenth-century social thinkers that could have had a huge impact on the twentieth century, as did Louis Henry Morgan. All well-known sociologists influence their society in at least two ways: one is direct, resulting from their contribution to social science or philosophy; the other is hidden, and the camera changes the whole Culture’s view of the world and society. These two effects can be seen as the scientific front and the fifth column. To distinguish whether a scholar is a real scientist or a member of the fifth column, it is of paramount importance at first to distinguish this point from that of the other scholars and to compare with other scholars.
