Tackling the question of why medieval philosophy matters in the current age, Stephen Boulter issues a passionate and robust defence of this school in the history of ideas. He examines both familiar territory and neglected texts and thinkers whilst also asking the question of why, exactly, this matters or should matter to how we think now. Why Medieval Philosophy is also provides a introduction to medieval philosophy more generally exploring how this area of philosophy has been received, debated and, sometimes, dismissed in the history of philosophy. This stimulating and highly original book makes a powerful case for the relevance of medieval philosophy to the methodology and content of contemporary natural sciences. It will be read with profit and great interest by all interested in medieval philosophy and its significance for the modern world.
