Step-by-step explanation:
According to Goldstein's quotation of Socrates, the true champion of justice should approach politics by seeking wisdom and basing their decisions on reason rather than on unchallenged traditional beliefs. Socrates believed in using the Socratic method, a series of questions that forced individuals to examine their own biases and arrive at truths through rigorous application of human reason. This approach helps individuals arrive at fixed, unchanging rules of truth and ethics.
