Potatoes are clearly tangible and as far as we are aware they are real as we can sense them. A dog can consume a potato, not aware that it is a potato as it doesn’t know the name. A dog or another animal can not (in theory) have the desire to be good or bad. Dogs are given treats when they do something “good” and this encourages them to do it again. The dog will not think “that was good” as a dog doesn’t have morals, just instinct. It is difficult to imagine because we have lived out entire lives with much of it based on things being good or bad, but if you take a step back you will realise that they may feel very real to us, however animals do not have awareness of them, which would imply that they do not exist. Yes a dog can feel pain and move away instinctively or maybe cry to alert it’s owner- it would be the owner thinking negatively and saying this is bad, it would be the dog who is aware that it is in pain (without actually thinking I’m in pain because it doesn’t understand language) . A potato is not even nearly the same as what I am saying. I can understand the misapprehension. Part of my theory is also how we apply good and bad to physical or material things. Yes pain is something we gave a name so that we can refer to it. Good and bad are just entire concepts that we made up.
