The empiricist distrust and fear of metaphor is wonderfully summed up by Samuel Parker:
All those Theories in Philosophy which are expressed only in metaphorical Termes, are not real Truths, but the meer products of Imagination, dress’d up (like Childrens babies) in a few spangled empty words____ Thus their wanton and luxuriant fancies climbing up into the Bed of Reason, do not only defile it by unchaste and illegitimate Embraces, but instead of real conceptions and notices of Things, impregnate the mind with nothing but Ayerie and Subventaneous Phantasmes. [Free and Impartial Censure of the Platonick Philosophy (1666)]
