Summary
This quote implies that a critic is someone who offers opinions and advice on a subject they have no practical experience or ability in. Comparing a critic to a legless man teaching running suggests that they lack the fundamental qualities to perform the task they are criticizing. It highlights the paradoxical nature of their role, as they critique and analyze something they cannot actively engage in or comprehend fully. Thus, the quote implies that critics should be viewed with skepticism if their insights are not grounded in practical knowledge or experience.
