Fear

All that we do,all that we do not do, all of our actions, conscious and unconscious, boil to down to one simple thing,one primary vestige that has remained within us from the time the human race came into existence, and that is FEAR.
Look at every action of yours.Look at what you have done today.Apply the "Five Whys" (as the Japs call it) and you will realise that somewhere deep beneath you were afraid of something.We are all animals at a very basic level.We need to survive.We need to protect ourselves.And as animals , even to this day,continue to live ,fearing the hunter,afraid of being a prey, our human race has built around itself a fortress of civilization.
And inside the ramparts of this fort we cozily believe that whatever we do has a motive driven by our desires which we attribute it to our civil nature.And almost bordering on hypocrisy is our tendency to claim that we are beyond "the sum of all fears".
If people apply fairness creams it is because they fear being dark in color,if people brush their teeth it is because they are afraid of cavities,and the big "soap-toothpaste" selling companies are actually selling fear.But, that marketing manager does not know that it the fear itself which makes him sell fear.
