Austin Farrer writes, “For though argument does not create conviction, the lack of it destroys belief. What seems to be proved may not be embraced; but what no one shows the ability to defend is quickly abandoned. Rational argument does not create belief, but it maintains a climate in which belief may flourish.” (Austin Farrer, “The Christian Apologist” in Light on C.S. Lewis, 26)
Even though argument and logic cannot create true conviction, they maintain a climate where belief can take root and grow. It gives us room to explore our thoughts and feelings on a given concept.
