Ninety per cent of the world's woe comes from people not knowing themselves, their abilities, their frailties, and even their real virtues. Most of us go almost all the way through life as complete strangers to ourselves - so how can we know anyone else?
It is still not enough for language to have clarity and content... it must also have a goal and an imperative. Otherwise from language we descend to chatter, from chatter to babble and from babble to confusion.
