The issue, then,. Is not whether the belief system you espouse – monotheistic, atheistic, pantheistic, or otherwise – is exclusive. The issue is whether the answers to the four basic questions of life pertaining to origin, meaning, morality, and destiny within the context of each of these world-views meet the tests of truth. Are they logically consistent, are they empirically adequate, and are they experientially relevant? The answers to life’s four questions must in each instance correspond to reality, and the sum of the answers must cohere as a system.
