“Only remember, that in writing, perspicuity is always more than half the battle: the want of it is the ruin of more than half the poetry that is published. A meaning that does not stare you in the face is as bad as no meaning, because nobody will take the pains to poke for it.”
Except graduate students. Perspicuity is a fine word and a fine quality in writing. As Sir Thomas Browne puts it in “Of Crystal” in Pseudodoxia Epidemica (1646-72): “Continuity of parts is the cause of perspicuity.” That leaves out Emerson and most of his descendants.
