We all know that for Dignāga the meaning of a word is apoha ‘exclusion’. But how does one seize it and avoid the infinite regress of excluding non-cows because one has understood what “cow” means? Kataoka at the last IABS maintained (if I understood him correctly) that Dignāga did not directly face the problem of how could one seize the absence of non-cows. He also explained that the thesis he attributes to Hattori and Yoshimizu, which makes the apoha depend on the seizing of something positive (e.g., one seizes the exclusion of non-cows because one seizes the exclusion of dewlap, etc.) contradicts the negative nature of apoha, since it indirectly posits positive entities, such as dewlaps. But this leaves the question of how apoha can take place in the worldly experience open.
