[170d]
Socrates
And yet this is the predicament to which the doctrine that man is the measure of all things inevitably leads.Theodorus
How so?Socrates
When you have come to a decision in your own mind about something, and declare your opinion to me, this opinion is, according to his doctrine, true to you; let us grant that; but may not the rest of us sit in judgement on your decision, or do we always judge that your opinion is true? Do not myriads of men on each occasion oppose their opinions to yours, believing that your judgement and belief are false?
