english: It's because we don't think rocks can suffer. And if we're more concerned about our fellow primates than we are about insects, as indeed we are, it's because we think they're exposed to a greater range of potential happiness and suffering.
non_english: Zato što ne mislimo da kamenje može da pati. I ako smo zabrinutiji za naše primate nego za insekte, kao što i jesmo, to je zato što smatramo da su oni izloženiji većem stepenu potencijalne sreće i patnje.
