We all are dumb at many things (IM 389))

We argue that we are smart. But the truth is we're not. In this vast universe there are billions people and there are billions and billions thing we don't even see, touch, hear, taste or feel. And those thing that we can't see, hear, feel, taste, or touch can't be even brought into mind and then into action. So, we don't know most things that exists in this world. We try to be smart and pretend that we know a lot of the information. But that's not true. So, we all are dumb at many things.
