consideration....................

 If we sometimes spent a little consideration on ourselves, and employed in probing ourselves the time we put into checking up on others and learning about things that are outside us, we would easily sense how much this fabric of ours is built up of feeble and failing pieces.  It is not singular evidence of our imperfection that we cannot establish our contentment in any one thing, and that even in desire and imagination it is beyond our power to choose what we need?

-Michel de Montaigne, The Complete Works, Book 1, Chapter 53
