Whenever the causal potency of something depends on convention, that [potency] cannot be its natural capacity; for instance, [as in] the comprehension [arising] from the winking of an eye; and the causal potency of a word in bringing about comprehension [of meaning] depends on convention; thus [this is] the cognition of something contrary to the pervader.
