Matching Quote

"The main objection to religious myths is that, once made, they are so difficult to destroy. Chemistry is not haunted by the phlogiston theory as Christianity is haunted by the theory of a God with a craving for bloody sacrifices. But it is also a fact that while serious attempts are constantly being made to verify scientific myths, religious myths, at least under Christianity and Islam, have become matters of faith which it is more or less impious to doubt, and which we must not attempt to verify by empirical means. Chemists believe that when a chemical reaction occurs, the weights of the reactants are unchanged. If this is not very nearly true, most of chemical theory is nonsense. But experiments are constantly being made to disprove it.... Chemists welcome such experiments and do not regard them as impious or even futile."

-J.B.S. Haldane
