[The fact that there are people finding the existence of the Universe (or of an Universe attuned for the apparition of intelligent beings) surprising could motivate this conceptual investigation.]
A box is labeled “Surprise”. What should it contain, in order for the content to be adequate to the label (or the label to be right)? Something which one does not expect to find in a box, perhaps. Sure, the box could contain some living creature answering to the name of ‘Surprise’, but that is besides the point.
