Selfishness...

In my personal opinion, which I know not many would agree... the word selfish is one of the most besmirched words. Further to add I wouldn't respite from adding that "selfishness is the crux to survival and extinction". I say extinction because, as i have already commented in my earlier posts, too much of anything is never good and that it often leads to results that can ever be treasured or cherished...
Now having laid the stage for my arguments, let me continue talking about the fundamental truth - "Selfishness". In my opinion, every being in this world is selfish and if that had not been the case, I doubt our existence and this blog that you r reading. Lets consider a hypothetical world (I call it so 'cos i believe dat selfless world can't exist) where each being is selfless and lets go of each and everything that they posses/possessed/will possess, then do you think the evolution would have happened? And in that case, we would have to redo our coursework for biology and the Darwinian theory which talks about the survival of the fittest. Now with that thought, lets move on the evolutionary track... since we know that all traits we possess are resultants of the evolutionary precess... and is the case with "selfishness'.
Now lets talk about ourselves, how many times in your (however many years u've walked this earth) have you done something big or small selfless... selfless which is marked by the distinction that u did not even derive pleasure out of the act (irrespective of the time frame when u get back the returns). What I want to point out is the fact that there is always a bigger picture to any relationship which at most instance is abstracted and only we know about...
Ok, now here is a thought... talking about people who say they do selfless social service... do you really think they are as selfless as they portray themselves....?
