PlatoI exhort you also to take part in the great combat, which is the combat of life, and greater than every other earthly conflict.
PlatoMy plainness of speech makes people hate me, and what is their hatred but a proof that I am speaking the truth.
PlatoSOCRATES: Perhaps we may be wrong; if so, you in your wisdom should convince us that we are mistaken in preferring justice to injustice. THRASYMACHUS: And how am I to convince you, he said, if you are not already convinced by what I have just said; what more can I do for you? Would you have me put the proof bodily into your souls?
