"Let us hold our discussion together in our own persons, making trial of the truth and of ourselves"

This quote by Protagoras motivates us to engage in significant dialogue and to check the truth of our beliefs. He suggests that we must not depend on external sources to identify the fact, however rather that we must use our own experiences and knowledge to come to our own conclusions. He motivates us to have an open and honest conversation with each other, and to use our own judgement to evaluate the reality of our beliefs. This quote encourages us to think seriously and to challenge our own beliefs, along with those of others. It also encourages us to be available to originalities and to be happy to alter our beliefs if we discover that they are not supported by proof. Eventually, this quote motivates us to be honest with ourselves and to utilize our own judgement to identify the truth.
