Answer:
a.These are simply those that are regarded as important to maintain social order in society. The Family Institutions, Political Institutions, Educational Institutions, Religious Institutions etc. These Institutions are a bit complex in the way that they aren't necessarily so much in order to maintain social order.
b.Well this is mostly a subjective point of view, society has no objective importance and everyone see’s it differently. As seen in the news over the past year or so a lot of people are blaming society for several of its current gender issues, racism, ect. To these people it is very serious, however it is a subjective view they hold for no one can really say that society is pushing gender inequality, racism, ect. As the social norm because most people I’m sure would say these are terrible things. However regardless of the truth it is still a subjective view they hold, but there is still importance of society in this view. For a moment let’s assume that society is pushing this as a social norm, and people begin to recognize it. In this case society’s importance lies within being the indentifyer of this problem, for if the problem didn’t exist, and society was not there to push it, no one would really notice this issue as a whole because it is not directly around them. In my opinion society’s importance lies elsewhere, namely in shaping people. “You are what you eat” in this case what you eat is what people around you are feeding you, so society’s responsibility and thus it’s importance lies within shaping people. It is and individuals job within a society to be an ethical and moral thinker to be able to shape those around then, thus creating a good and prosperous society. However this is my subjective idea, if you would like an answer on society’s importance I suggest the reader to sit down, right a few thoughts on a page or in your head, and truely think about it for a good 10–20 minutes, as time goes on and as you talk with people this will basically answer itself in the right way. Regardless if you think society is good or bad, the only objective truth to the importance of society, is that itself does hold a form of importance.
