...the best figurative poetry speaks not to the frivolous intellect, but (if anything does) straight to the heart; and does it better than plain prose. There seems then to be something which is better said with metaphor than without, which goes straighter to its mark by going crooked, and hits its aim exactly by flying off at tangents.
It is commonly said that if rational argument is so seldom the cause of conviction, philosophical apologists must largely be wasting their shot. The premise is true, but the conclusion does not follow. 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.
