Most publications of the correspondence of Erasmus and Luther over the question of Free Will only include Erasmus' first letter and Luther's reply. The fact that Erasmus made a defense of his first letter often goes unnoticed. This book rectifies the problem. Erasmus explains why, though he does have an opinion on the issue, he does not speak forcefully in his first letter, but rather tries to be conciliatory. He then takes time to respond to each of Luther's criticisms. It is unfortunate that Luther was so vitriolic and insulting in his tone. Later he tried to regain Erasmus' friendship, but to no avail.The book received five stars despite the fact that it still does not have the full correspondence between Erasmus and Luther, rather, selections of each of their letters (along with an outline of the entire work). This is because, for the price, you cannot get a fuller English text of the conversation and the book would have had to have been probably twice as long as its already almost 400 pages. Nonetheless, for those who want the entire conversation, they will have to look at the complete works of Luther and Erasmus.The book was definitely worth the money and the time I put into it.
