Professor of Mathematics and philosopher of science at University of Oxford John Lennox has stated, "Faith is not a leap in the dark; it’s the exact opposite. It’s a commitment based on evidence… It is irrational to reduce all faith to blind faith and then subject it to ridicule. That provides a very anti-intellectual and convenient way of avoiding intelligent discussion.” He criticises Richard Dawkins as a famous proponent of asserting that faith equates to holding a belief without evidence, thus that it is possible to hold belief without evidence, for failing to provide evidence for this assertion.
