Lets consider all the objects and concepts in the world, in our reality, in our MIND. Notice Im going to call it mind instead of soul. Lets say these things have only ONE property: they are, or they aren't useful. Nothing more than that. I'd say that every real object in our reality is useful. I say object not only as a table or a dog, but concepts and abstract stuff. You know what I mean. Well.

To know if an object IS useles or NOT we must have some information about it, we must have at least one fact. I think this is very easy to accept, if we have no information about an object, we dont know how to handle it, we can't be sure about its existence. Its not useful.
Im talking about sensitive information, this is, given by our senses or innate intuitions. An innate intuition for example is a triangle, even an illiterate person knows in his mind that its an object with three sides, even if he never sees one in his life.

Ok, lets see some examples.
A pen: Known facts: We use it to draw, its a material object.
Useful? Yes
A circumference: Its not a material object. A blind person could imagine it in his mind. Its an innate intuition, so It does exists.
Useful? Yes
An unicorn: It DOES NOT exist.
Useful? Yes. We know a fact about unicorns so therefor is a real CONCEPT.
God: We dont know any facts about God.
Useful? According to this theory, It is not. And according to this, It does not exist.

Well, this is a little theory I have. Of course its not as simple as this, but its a try ;)
Its a matter of accepting that we must have at least one fact about something, in order to consider it real. We can't say god exists but we can't say It doesnt exist.

You could talk about faith. But faith is a blind feeling. Its about hope. I dont have faith in God. I believe in life itself.

It would be interesting If you would discuss this topic with me. I dont want to be polemic. I just want to share my feelings and see what others think, in a respectful way.
