It is a religion book. The 'Sermons on Human Nature' is commonly studied as an answer to Hobbes' philosophy of ethical egoism. The quality of his sermons comes from the strength of his intellectual arguments and reasoning. There he had a friend and comrade, Seeker, who afterwards became Archbishop of Canterbury. Butler and Seeker inquired actively, and there was fore shadowing of his future in the fact that in 1713, at the age of twenty-one, Butler was engaged in anonymous discussion with Samuel Clarke upon his book on the priori demonstration of the Divine Existence and Attributes. When the time drew near for call to the ministry, Butler, like his friend Seeker, had reasoned himself into accordance with the teaching of the Church of England. Butlers father did not oppose his strong desire to enter the Church, and he was entered in 1714 at Oriel College, Oxford. At college a strong friendship was established between Butler and a fellow student, Edward Talbot, whose father was a Bishop, formerly of Oxford and Salisbury, then of Durham.
