Bravo, Legolas.
But I disagree about the unpercieved insect. The insect percieves itselfs, therefore it is there. A tree can not percieve itself because it has no intelligent life and thus vanishes and ceases to exist until someone comes who is able to percieve it and it comes back into our existence. Therefore, when we come to a fallen tree which has been grounded the last time we checked, the falling is occured on an infinitesimal amount of time needed to make all adjustments to other trees in the area and is then percieved by us as a fell tree.
