Need for improvement is indicated by critical references to a variety of past studies, including some of the author's own. A main emphasis is on pragmatism in being guided in research and analysis by the goal of causal explanation. Among the issues considered in accord with this emphasis are the nature of causes and causal explanation, ways of judging explanations and explanation-oriented research, the use and misuse of generalizations, the use and misuse of evidence, prioritizing in research, moving from one level of analysis to another, and the uses made of statistics. Because of space constraints, most of the arguments and illustrative data are presented in compressed form, but some suggestions and references for their elaboration are provided, especially in the sometimes quite lengthy endnotes.
