When we accept a new 'truth' we go beyond old 'facts'. The beliefs and notions of today probably can achieve the stature of being hypotheses tomorrow. It's undoubted that beliefs are in some way responsible for designing the theories of future. There always are cases where humans believe in a few things existing but lack explanation. There always are some ideas existing in nature. We can feel them; we can believe in their existence but cannot accept them till their existence is reasonably proved. Our beliefs are circumscribed by reasoning. We all believe in the connection between various things. No one can deny this. All things may consistently follow each other but that does not reveal any relation between them. There is ambiguity because the connectivity in our mind is cooked up work.
