This reading was interesting to me because the approach to understanding knowledge took a change from explaining ones beliefs to teaching ones beliefs and making an institution of the process. What really captured my attention was the fact that these sophists charged their pupils money. In my opinion this cheapens their ideas, putting such precious knowledge at a price seems degrading. If their ideas were considered to be knowledge without qualification, then why would these sophists put a price on knowledge which they felt the general public should become familiar with. On page 145 in the first fragment it recounts of a passage where Protagoras is convincing a pupil of how he could become better. Then from becoming better he will then be the most powerful in acting and in speaking. Protagoras seems to be using a political pull in order to attract more students. He seems to be selling his knowledge for the price of obviously money but also power. Humans are naturally attracted to power and Protagoras uses this in attempt to entice more followers. In the introduction it reports that Plato denoted the fact that the sophists charged for their teachings. He also commentates on how sophists in a way are begging the question because they are said to be teachers of wisdom and yet when these sophists teach, they are working to define wisdom and understand its elements.
The way Protagoras attempts to spread his ideas is dissatisfying and makes the process of learning innovational information distasteful and devalues the knowledge itself.
