Where did the peasants get some of their ideas about equality and freedom?

Peasants simply decided that it was time to take a stand and support the ideas proposed by John Ball who encouraged peasants to plea their case before the king. Many were the reasons why the peasants get some ideas about equality and freedom and revolted:

1) They realized how unequal they were from anyone else - nobles were attempting to reimpose medieval dues.

2) They realized they were receiving an unfair treatment - peasants were starving and there was a lack of simpathy for poor.
