The tree’s problem doesn’t come from its bareness‚ the tree’s problem is its self awareness of its bareness. The tree simply wants self ignorance. Maybe because the tree also knows that the woodcutter can’t provide the separation of the tree with its shadow‚ it is even more dejected. In the second stanza‚ we learn that

about humanity? The "Allegory of the Cave" by plato features in Plato’s republic. It is a dialogue narrated by Socrates‚ in which he describes prisoners in a cave looking at shadows which they perceive to be reality.

A broken mirror‚ a bleeding fist‚ a silver blade against a wrist‚ tears falling down to lips unkissed‚ she’s not the kind you’ll come to miss.” (http://xxdailydreamxx.tripod.com/id16.html) I took this poem from an
