Sorry, but you forgot the last part of the saying, the unwritten one. 😉
<"All I know is that I know nothing" compared to what is to be known !>
That is the correct idea. 🙂
There is so much to be known in the world (or in the Universe, if you prefer), that all we know at an instant of time is nothing compared to the rest of it.
To prove/feel/see that, just try to answer the first (any) ten Yahoo! questions. 🙂
P.S. Just one word for panty_rider (I hope you won’t mind, Mad Scientist) :
There is an absolute purpose to life : to live !
Life tries to live.
And the best way to live longer is to die hard :), or to be hardly destroyable.
More complex you are, harder to be destroyed you are.
That’s why life should be complex, that’s why we are living for and why our life is important : to give more and more complexity to the life.
