 We find ourselves naturally inclined to make certain judgments about which objects are before us in various situations. Looking at a pool table just before the break, we are naturally inclined to judge there to be sixteen pool balls on the table, perhaps various parts of the individual balls (their top and bottom halves), and no other macroscopic objects. Looking at my nightstand, I am naturally inclined to judge there to be an alarm clock, a lamp, their various parts (lampshade, buttons, cords), and nothing else.
