In the period leading up to the Scottish Reformation, there was intense debate in Scotland over matters of faith. This probing study delves into the Pre-Reformation Scottish philosophers' understanding of the concepts of faith, and the relationship between will and intellect -- questions which more than any other characterized philosophy and theology in the Middle Ages.From John Duns Scotus (1266-1308), the greatest Scottish philosopher of his age, to his 15th and 16th century successors, John Ireland, John Mair of Haddington and George Lokert of Ayr, this book is the only comprehensive study of Scottish philosophy from the 12th to the 16th centuries, and proves that the Scottish Philosophical School began well before the Enlightenment.
