breaking philosophies (E) chapters 17-19

For many philosophies or principles are the most important thing in their lives. to a certain point they are what drives our desires and goal in life, but when is it O.K. to break our principles? Is it under extreme situations? or just when change is needed? for the Joads, the answer is, under extreme situations. Not only them but many other farmers or "Okies" had to break their philosophies in order to survive. Separation, is one of the most remarkable ones in this sections. It appears several times throughout it as well. Either because of death, sickness, or just basic needs or desires; separation happens in chapter 17.The death of Granma followed by Noah leaving the group and having to leave the Wilsons behind fills the atmosphere with a sense of despair and loneliness. thoughts such as "our family is falling apart" fill the joads' minds. Although, proud of their independence, farmers accept their need for each other, and this need is denied by the separation of their group.
