The idea of different temperaments or tunings brings me back to another metaphor that has been hovering in my thinking about these early remarks. That of tiles, or tessellation. The tiles, though, are not regular (though each may be self-consistent & even beautiful). The tiles are language games. Sometimes they nestle up against each other & make interesting, useful & beautiful larger patterns; but we can never assume that the surface can be tiled completely, without gaps. This is not a jigsaw puzzle to be "solved"--there is pattern but no solution. Only human being moving the tiles around & telling stories about what they see.
