Why can't science logic or reason justify belief? I say that it can, if it is logical - scientific or reasonable!
If belief requires an existence in the mind before the investigation of its'validity then I would question how you detach your bias from the investigation? It is my observation that people who believe state that the only way to knowledge about the things they are trying to establish is if you first believe then you will see the validity of the belief and not before.Are you stating here that the belief can stand alone on its own logically?
Is that the one where you introduce these premises?
P 1. Everything in existence has a possible purposeful use. P 2. The nature of the universe is diverse and there are recognized systems in place.
I would ask if you can think of anything that would contradict either of these premises? Also as concerns #2 that there are recognized systems in place are you refering to man made systems or natural ones?
