Joseph Butler, whose _Sermons_ (1726), and _Analogy of Religion Natural and Revealed to the Constitution and Course of Nature_ (1736), are among the highest contributions to theology produced in the last century, called the imagination 'a forward, delusive faculty,' and he could have boasted that it was a faculty of which no trace is to be found in his works. Moreover, he is generally regarded as wholly destitute of style, and in a sense this is true, for Butler is so intent upon what he has to say that he cares little how he says it. His sense of beauty if he possessed it, was absorbed in a supreme allegiance to truth, and his life was that of a Christian philosopher intent upon one object. His sermons, preached at the Rolls Chapel, which contain the germ of his philosophy, are too closely packed with argument and too recondite in thought to fit them for pulpit discourses. The _Analogy_, which occupied seven years of Butler's life, is better known and more generally interesting. 'There is,' he says, 'a much more exact correspondence between the natural and the moral world than we are apt to take notice of.' His aim is to show that the difficulties which meet us in Revelation are to be found also in nature, that as our happiness or misery in this world largely depends upon conduct, so it is reasonable to suppose, apart from what Revelation teaches, that we are also in a state of probation with regard to a future life. As youth is an education for mature age, so may the whole of our earthly life be an education for a future existence.
