 We should also note that in the same passage of his commentary on the Categories, Boethius linked deliberate equivocation with metaphor, in which the sense of one word with an established signification was extended to apply improperly to something else. A favourite medieval example was ‘smiling’ said of flowering meadows. Later logicians supported this link between equivocation and metaphor by an appeal to Aristotle’s divisions of equivocation in his Sophistical Refutations, where he remarked that the second type was based on common usage. As we shall see, the question of metaphor’s relation to analogy became particularly important in post-thirteenth-century discussions.
