引言(Preface)·Plato将世界分为两个层次：本质世界（World of being）和形成世界(World ofbecoming) Plato divided the world into two Jevels: Worldof being and World of becoming.·科学家（哲学家）白的职责在于超越可以观察、感受和经历的事物而获取本质世界中的真理，即研究本质世界 The duty of a scientist (philosopher) is tostudy the world of being

引言(Preface) • Plato将世界分为两个层次：本质世界 （World of being）和形成世界（World of becoming） • Plato divided the world into two levels: World of being and World of becoming. • 科学家（哲学家）的职责在于超越可以观 察、感受和经历的事物而获取本质世界中 的真理，即研究本质世界。 • The duty of a scientist (philosopher) is to study the world of being 3

引言(Preface)·Plato的理论不但对于自然科学的启蒙和发展有着极其深远的影响，而且对于包括社会科学在内的整个西方哲学都具有深远影响: Plato's theory has a profound influence on thenatural science and social science

引言(Preface) • Plato的理论不但对于自然科学的启蒙和发展 有着极其深远的影响，而且对于包括社会科 学在内的整个西方哲学都具有深远影响。 • Plato's theory has a profound influence on the natural science and social science. 4

引言(Preface)，自然科学是以发掘“永恒世界”中的真理为最终目的 The ultimate goal of natural science is todiscover the truth (rules) of the World of being·社会科学以了解“变化的世界"为最终目的而不在于也不需要去挖掘永恒的真理 Social science aims to understand the"changing world

引言(Preface) • 自然科学是以发掘“永恒世界”中的真理为最 终目的 • The ultimate goal of natural science is to discover the truth (rules) of the World of being • 社会科学以了解“变化的世界”为最终目的， 而不在于也不需要去挖掘永恒的真理。 • Social science aims to understand the "changing world" 5

引言(Preface)·与自然科学不同，社会科学更加强调社会情景、社会差异和社会分组，因此Duncan奠定的定量社会科学研究新范式是建立在批判通过模仿自然科学以寻求普遍社会规律的研究范式的基础上的 Three basic principles of social scienceresearch: Variability Principle, Social GroupingPrinciple and Social Context Principle6

引言(Preface) • 与自然科学不同，社会科学更加强调社会情 景、社会差异和社会分组，因此Duncan奠定 的定量社会科学研究新范式是建立在批判通 过模仿自然科学以寻求普遍社会规律的研究 范式的基础上的 • Three basic principles of social science research：Variability Principle, Social Grouping Principle and Social Context Principle 6

引言(Preface)·随着统计学被引入社会科学研究，使得过去的50年中，社会科学总的趋势是向更为严格清晰的假设；更大更详细的数据集合发展With the introduction of statistics, the socialscience research becomes more rigorous andempirical (clear assumptions and large dataset)

引言(Preface) • 随着统计学被引入社会科学研究，使得过去 的50年中，社会科学总的趋势是向更为严格、 清晰的假设；更大更详细的数据集合发展。 • With the introduction of statistics, the social science research becomes more rigorous and empirical (clear assumptions and large data set ) 7

引言(Preface)·统计方法在社会科学领域成功地走过了半世纪，一方面使得该学科研究的水平有了重大的提高，另一方面为了拟合数据，统计模型变得越来越复杂。Statistical models are becoming more anomorecomplex

引言(Preface) • 统计方法在社会科学领域成功地走过了半世 纪，一方面使得该学科研究的水平有了重大 的提高，另一方面为了拟合数据，统计模型 变得越来越复杂。 • Statistical models are becoming more and more complex 8

引言(Preface) • Adrian. E. Raftery: Statistics In Sociology, 1950–2000: A Selective Review • He identified three overlapping postwar generations of statistical methods in sociology, based on the kinds of data they address. The first generation, which started in the late 1940s, deals with cross‐tabulations and focuses on measures of association and log‐linear models, perhaps the area of statistics to which sociology has contributed the most. The second generation, which began in the 1960s, deals with unit‐level survey data and focuses on LISREL‐type causal models and event‐history analysis. The third generation, starting to emerge in the late 1980s, deals with data that do not fall easily into either of these categories, either because they have a different form, such as texts or narratives, or because dependence is a crucial aspect, as with spatial or social network data. There are many new challenges, and the area is ripe for statistical research; several major institutions have recently launched new initiatives in statistics and the social sciences. • 以交互表为代表的第一代统计方法，和面向个体层次调查数据的第 二代统计方法都关注属性研究，作为第三代统计方法关注的社会网 络数据，侧重关系研究，需要发展新的分析方法。 9
