"A world where all would be silent and still and each thing in its last place"

Clov explains his desire for order as he tidies up the room (in Part four). Unbeknownst to him (but known by Beckett), a perfectly disordered room would also be "silent and still"; it would have equal distribution of energy and motion would cease. Just as beginnings and endings are the same in Endgame, disorder and order can be viewed as the same thing.
