"Philip Wheelwright's 1962 classification of metaphors into "epiphors"
(metaphors that express the existence of something) and "diaphors"
(metaphors that imply the possibility of something). Diaphor and epiphor
measure the likeness and the dissimilarity of the attributes of the
referents. A diaphor can become an epiphor (when the object is found to
really exist) and an epiphor can become a literal expression (when the term
has been used for so long that people have forgotten its origin). "
