Story telling is not in our genes. Neither it is an evolutionary history. 

It is the essence of what makes us Human. Human beings progress by 

telling stories. One event can result in a great variety of stories being told 

about it. Sometimes those stories differ greatly. Which stories are picked 

up and repeated and which ones are dropped and forgotten often determines 

how we progress. Our history, knowledge and understanding are all the collections

 of the few stories that survive. This includes the stories that we tell each other about 

the future. And how the future will turn out depends partly, possibly largely, on which 

stories we collectively choose to believe. Some stories are designed to spread fear and 

concern. This is because some story-tellers feel that there is a need to raise some tensions.

 Some stories are frightening, they are like totemic warnings: "Fail to act now and 

we are all doomed." Then there are stories that indicate that all will be fine so long 

as we leave everything upto a few especially able adults. Currently, this trend is being 

led by those who call themselves "rational optimists". They tend to claim that it is 

human nature to compete and to succeed and also to profit at the expense of others. 

The rational optimists however, do not realize how humanity has progressed overtime 

through amiable social networks and how large groups work in less selfishness and in 

the process accommodate rich and poor, high and low alike. This aspect in story-telling 

is considered by the 'Practical Possibles', who sit between those who say all is fine and 

cheerful and be individualistic in your approach to a successful future, and those who ordain 

pessimism and fear that we are doomed. What the future holds for us is which stories 

we hold on to and how we act on them
