“An extraordinary claim requires extraordinary proof.”
“the burden of proof falls upon the claimant”
“The true skeptic takes an agnostic position”
“the claim is not proved rather than disproved”
“Science is a constantly changing body of knowledge characterized not so much by its content as by its method”
“Those concerned with metaphysics and supernatural claims are directed to those journals of philosophy and religion dedicated to such matters.”
“do nothing that would block inquiry.”
“Without anomalies and their validation, later incorporation, and explanation, we would not have any progress in science.”
“Absolute truth, like absolute justice, is seldom obtainable.”
“We can only do our best to approximate them.”
