The thought-provoking riddle posed by these 17 syllables (presented here as 3 square stanzas) from Ludwig Wittgenstein (1889-1951) is something I found on the the wall of the National Gallery of Modern Art in Rome, not far from a replica of "Fountain" by Marcel Duchamp (1887-1968). Photos of both are shown below.

|Duchamp also experimented with representations of the 4th dimension. Consider, for example, his "Nude Descending a Staircase."|
