Knowledge

In religious school, we have been discussing: What is the meaning of knowledge? It seems to be one thing when we consider objects that we can sense with our 5 senses. It feels like we can really know everything there is to know about those objects, so we have real knowledge about those things. But when it comes to something more abstract, like knowing about yourself, that’s more “thought” than knowledge. It seems to be the same about G-d, that we can’t see him with our 5 senses so he’s more thought than knowledge.
Do you agree?
