What can we really know...

if we do not know our-selves?
 
All we will know is what other's have learned or told us is true about the world and maybe what they perceive as true about us.  But even knowledge, information and theories change--as do opinions.
When we know ourselves, we naturally want to grow, change and expand who that person is.
When we know ourselves we can know every-thing and no-thing at all!
(and that my friends-- is the Riddle of Life, so enjoy the puzzle!)
