We have so far sketched in broad outline the main dimensions of social change in early twentieth-century Britain. In so doing we have implicitly used theories of social change. In concluding we need to discuss some of these briefly. We cannot of course hope to settle such fundamental issues as the factors of social change or the role of the individual in history in the paragraphs which follow, and some readers may prefer to skip them. But we can at least indicate the theoretical position from which this book began and to which —hopefully-it leads, and in so doing suggest some possible avenues for further exploration. After this we shall return finally to the raw material upon which both the discription and analysis of social change must ultimately rest, the life experience of ordinary people.
