Logic (continued).

The below post was supposed to be an intro. It meant how to think. In this post ,I will just try to ask some simple questions. Here in these types of question has the significance because we take so much for granted. Ofcourse it has certain advantages that lot less to think about. And yes thinking does require effort like all other exercises.
Lemme start, The first question is simple Why is Colour "Black" associated with the devil, death, sadness etc? Why is "white" associated with all that is good ? Ofcourse these kind of questions are equally relevant for all other colours.
Hmm, here is the second question Why do we cut our hair?(Ofcourse ,My hair is damn short.)Why do we shave? Why do we have a midday meal, it is not as if we will starve if we dont get that meal? If food intake is the point why not have a five meal day with lesser food per meal?

The first ones were arbitary and second one is related to action. Ok Here is the third. Why do we have family. That is I agree there is importance in a social structure. But why should that structure be the family as it is now. Of course then Why should we divide all the world into countries (If india can exist two steps more World can be unified under one structure. Join India and China 1/3rd of the world then becomes one country.) These are all arbitary but they do have ease of use over some other existing structures. That is they are the best available now.
If any thing is amiss then do comment.
