This paper explores the conception of philosophy as a divine mission in Plato's works, specifically focusing on the Apology and the Theaetetus. The author proceeds from the premise that Socrates viewed his philosophical activity as a duty bestowed by the gods, which strictly forbade him from acquiescing to falsehood or suppressing the truth. A central point of analysis is the passage from Theaetetus (151d), where Socrates’ stance on the impermissibility of obscuring truth is examined. The text provides a detailed linguistic analysis of the Greek terms alēthēs and pseudos, comparing them with modern English translations by J. McDowell and H. N. Fowler. It demonstrates how translation choices, particularly regarding the absence of the indefinite article in Greek, can significantly alter the substantive meaning of the original text. Ultimately, the paper concludes that for Socrates, philosophizing was not merely an intellectual pursuit but a profound ethical and divine obligation to maintain a critical relationship with the true and the false. This rigorous commitment to distinguishing truth from deception constitutes the core of Socratic method and ethics.
