Uf, that is a very interesting question to ponder on.

I think belief is much more than knowledge. But it is my personal negative opinion about 'knowledge.'

For example: 'Knowledge is useless if you don't know how much (of the whole) you know/don't know.' It cannot even be called an estimation.

OK so, is belief knowledge? If I truly believe 'I Am God,' then belief is the reality. ;)
