Why did Aristotle become known as “The Philosopher” during the late Middle Ages?

During the late Middle Ages, Aristotle became known as "The Philosopher" because his works formed the foundational intellectual framework for Western Scholasticism. Following the rediscovery and translation of his writings into Latin in the 12th and 13th centuries, his systematic approach to logic, science, and metaphysics became the dominant authority in European universities and intellectual life.1234

This status was solidified as scholars like Albertus Magnus and Thomas Aquinas integrated his thought into Christian theology, making his treatises a required part of the curriculum. His influence was so pervasive that Dante Alighieri famously referred to him as "the master of those who know". Because his philosophy provided the essential tools for scientific inquiry and logical disputation, he was viewed as the embodiment of total human knowledge, leading to his singular designation as "The Philosopher".2154
