If you want to add something, or if you disagree, I'm still your student. Culture is always handed down from the past to the present, influencing the future. It is thus conservative, yet never static. It is continuously adjusting to a changing reality, but not parallel to that reality change. Culture is the modification of change, it is what ensures variety in a globalizing world by insisting on a local common denominator.
Culture is bound to space and time - and so are human beings.
As habits of the heart, culture operate mostly on the unconscious level, through feelings and behavior, considered normal in each given social environment. It is hard to discuss culture and what it does to people, because it is intangible. It is there, but it is difficult to prove. Values and norms are the fundamentals of culture. It is the glue that keeps societies together, invisible but effective.
