Atheism a requirement?
Wikipedia defines the supernatural as pertaining to an order of existence beyond the scientifically visible universe. The supernatural manifests itself as a belief and faith of the intervention in the natural course of nature, suggesting the existence of a consciousness, purposefully doing the intervening.
Science requires objectivism, which advocates reason, logic and proof as the sole means of knowledge. If one were to claim belief or faith in supernatural orders or sentinent beings (eg Gods), then it requires a wilful rejection of those objective principles in favour of what is arguably a flight of fancy or whim.
So, is atheism required to scientifically research phenomena attributed to the supernatural?
