The nature of method has always been a topic at the very heart of western philosophical traditions, especially in the 20th century. One of the most influential philosophers of the last century, Ludwig Wittgenstein, changed not just his philosophical standpoint at least twice in his lifetime, but the very method of studying philosophy as well. A Custodian of Grammar discusses Wittgenstein's method in his later period, sometimes referred to as morphology. Krkac explores this topic from the primer of morphology and proceeds to more demanding and complicated topics, such as forms of life and perspicuous presentations. He also examines Wittgenstein's applications of his method, namely to consciousness, perception, and certainty. This book will be of interest to Wittgenstein scholars and to students investigating various philosophical methods of philosophy from the 20th century.
