Wittgenstein shifted his focus from formulating doctrines and theories to emphasizing the importance of clarity in philosophical discourse. He believed that the role of a philosopher should be to show a method rather than simply presenting ideas or concepts. This change in perspective reflects a more practical approach to philosophy.

In Ray Monk's biography of Wittgenstein, "The Duty of Genius," the author portrays how this emphasis on method allows philosophers to facilitate understanding and tackle complex problems more effectively. Wittgenstein's approach prioritizes clarity, suggesting that philosophy should serve as a tool for better comprehension rather than an abstract system of thought.
