What do we call visible light? We call it color. But the electromagnetic spectrum runs to zero in one direction and infinity in the other, so really, children, mathematically, all of light is invisible.
~ Anthony Doerr in ALL THE LIGHT WE CANNOT SEE
The creative Wisdom of all things has established marvelous and ineffable harmonies by which all things come together in a concord or friendship or peace or love or however else the union of all things is to be designated.
