When I was born, I was stupid and remained so for many years. What else can you call the kind of things a baby does, crying, drooling, speaking gibberish, laughing for no specific reason. As I grew up, well, I have no idea if I ceased being stupid but I did learn that what is much more important than not being stupid is not being considered stupid. And to do that, all you have to do is not do the stuff the society considers stupid. Of course, if the society itself is stupid, you will not be considered stupid if you act stupidly. However, you might be perceived as stupid if you act wisely. But nobody knows if the society is stupid or not since society itself is the judge of that and nobody would have the shamelessness to admit that he or she is stupid.
So, I guess it is next to impossible to know if I am actually stupid or not. In a world occupied by babies, not drooling or speaking in understandable language might just be considered stupid. I think what I am trying to say here is that a stupid dog among intelligent humans is a stupid dog. But in the company of dogs, he is just stupid and among stupid humans, he is just a dog. But what about a wise human in the company of stupid dogs. Hmmm! He might be a stupid cow since stupid dogs won’t really know what to make of him. Understand? No? That’s fine, just hope that no one understands. That way none of us will be stupid.
