(1)The social science disciplines such as sociology, anthropology and history have been developed to explain puzzling social phenomena. They particularly investigate "collective" phenomena, that is, aspects of people's lives that are not unique to them, ones that they share with at least some others.
that is以下のto them, ones, they shareのtheyが指しているものがわかりません。
(2)Being able to give answers to questions such as "Why do these people typically or regularly do that?" or "Why did that event or kind of event happen when and where it did?" is a practical requirement of life for everyone.
(3)Effective human beings must have a practical, sound grasp of the concepts needed to analyse social reality, concepts which social theory makes explicit for the social sciences.
(4)The key point is that realists hold that there are many different kinds of causes at work producing social phenomena. Thus realism provides a good basis for introducing the varieties of social theory which seek to understand the causes of social phenomena.
