Abelard's sister adopted Astrolabe. Abelard opposed St. Bernard of Clairvaux , Abelard holding to both reason and faith. Bernard Fought for the primacy of the heart while Abelard fought for the primacy of reason. This controversy still rages on to this day, many sides never acknowledging that reason and faith are both important and must work together to validate revelation. Abelard and Bernard were to create a hellhole over this argument which later theologians were to enlarge by vain and endless arguments.
Faithful reason is just as important as reasonable faith.
Mis-interpretations have come when one or the other is not practiced. In 1140 a Church council and Pope Innocent II condemned Abelard for his writings. The prosecutor at Abelard's heresy trial was Bernard. Abelard alienated several church councils, abbots, bishops, his own monks, and most notably St. Bernard. The last months of his life were spent under the protection of Peter the Venerable of Cluny, where he died.
