The purpose of this book is to deal with Browning, not simply as a poet, but rather as the exponent of a system of ideas on moral and religious subjects, which may fairly be called a philosophy. I am conscious that it is a wrong to a poet to neglect, or even to subordinate, the artistic aspect of his work. At least, it would be a wrong, if our final judgment on his poetry were to be determined on such a method. But there is a place for everything; and, even in the case of a great poet, there is sometimes an advantage in.
