Why were people so worried about the Copernican universe?
	"And new philosophy calls all in doubt, The element of fire is quite put out; The sun is lost, and the earth, and no man's wit Can well direct him where to look for it . . . ' Tis all in pieces, all coherence gone, All just supply, and all relation . . ."         (John Donne, "An Anatomy of the World" ~ 1612)
