In the High Middle Ages, a revolution took place in Europe that continues to shape our lives today. Scholars freed themselves from the certainties of faith of their time and pursued their own questions. In his book, Frank Rexroth vividly and closely to the sources brings to life the experiences of medieval scholars, their innovative schools, their emotions, ideas, and discoveries, showing how what we now call science ultimately emerged. When Peter Abelard proclaimed the primacy of reason in all matters in the 12th century and began a relationship with his student Heloise, it was a scandal. However, he was not the only one who wanted to stubbornly explore knowledge for himself and dedicate his life to the new project of "scholastic" knowledge. Frank Rexroth narrates how students formed new groups and schools.
