Title:
Martin_Luther

Context:
In accordance with his father's wishes, Luther enrolled in law school at the same university that year but dropped out almost immediately, believing that law represented uncertainty. Luther sought assurances about life and was drawn to theology and philosophy, expressing particular interest in Aristotle, William of Ockham, and Gabriel Biel. He was deeply influenced by two tutors, Bartholomaeus Arnoldi von Usingen and Jodocus Trutfetter, who taught him to be suspicious of even the greatest thinkers and to test everything himself by experience. Philosophy proved to be unsatisfying, offering assurance about the use of reason but none about loving God, which to Luther was more important. Reason could not lead men to God, he felt, and he thereafter developed a love-hate relationship with Aristotle over the latter's emphasis on reason. For Luther, reason could be used to question men and institutions, but not God. Human beings could learn about God only through divine revelation, he believed, and Scripture therefore became increasingly important to him.

Question:
What did Luther think the study of law meant?
