I believe that,
Human wisdom
Can be summed up in one phrase:
"Full moon"
You can never see the moon "in full,"
Only half of it.
It's like,
When someone says,
"You have my full trust and devotion."
But that's only true,
Until someone better than you
Comes along to,
Give their "full" trust and devotion to.
And anyway,
The moon is never "full"
Very long either.
