However, Meno asks a question that Socrates classifies as the "debater's argument." The argument is: “How are you going to look for it, Socrates, when you have no idea what it is? How are you going to look for something you don't know at all? If you meet it, how will you know that it is the thing you did not know” (Plato 70)? Meno wonders how will they know what they are looking for if they have no prior idea of ​​what it is, and if they find it, how will they know. Because they have no idea what they are looking for, Meno believes that even if they discover the true meaning of virtue, they will have no way of knowing it. Socrates refutes this argument by inserting his idea of ​​the immortal soul. Socrates states that we all have an immortal soul, which already possesses all the knowledge we need as a man. However, as a man, we simply need to discover the knowledge that is within us. Through this concept of the immortal soul, Socrates believes that once they encounter what they are looking for, they will know that they have found.
