Gordon Hadfield

Before a star signified a brilliant point in infinite expanse, it marked the boundary; it marked the cosmic wall. Galileo knocked that wall over with his eye. But as Gordon Hadfield acutely shows, the bricks from one wall knocked over are recollected, and put to use again, keeping out what isn't allowed in, and keeping in what isn't allowed out. The human world repeats the cosmic one. But no boundary fully holds. —Dan Beachy-Quick
