Answer:
1. Social Change and Modernity
Because these terms enjoy wide usage in contemporary sociology and are general and inclusive, they seem preferable to more specific terms such as "evolution" "progress," "differentiation," or even "development," many of which evoke more specific mechanisms, processes, and directions of change.
2. Theories of Social Change
Change is such an evident feature of social reality that any social-scientific theory, whatever its conceptual starting point, must sooner or later address it.
