Those who would have men believe that religion is their own private property once more bring their efforts to bear against the Sun of Truth: they resist the Command of God; they invent calumnies, not having arguments against it, neither proofs. They attack with masked faces, not daring to come forth into the light of day.

Our methods are different, we do not attack, neither calumniate; we do not wish to dispute with them; we bring forth proofs and arguments; we invite them to confute our statements. 
- ‘Abdu’l-Baha  (From a talk, Paris, November 20, 1911; ‘Paris Talks’)
