The following question is based on the excerpt from “nobel prize acceptance speech” by john steinbeck. according to steinbeck in his “nobel prize acceptance speech,” all who consider themselves writers must hold a belief in a. the erroneous nature of humanity b. the irony of life itself c. the perfectibility of humanity

According to Steinbeck in his “Nobel Prize Acceptance Speech,” all who consider themselves writers must hold a belief in (c.) the perfectibility of humanity.

When talking about 'the perfectibility of humanity', Steinbeck is referring to people's capacity to achieve perfection through natural means. This concept is closely connected to Rousseau's philosophy, which establishes that perfectibility is part of the human development and it is expressed through nature. Moreover, in his speech, Steinbeck argues that all who consider themselves writers must believe in the human potential to achieve perfection and also in "the man's proven capacity for greatness of heart and spirit" since, according to him, this was the most effective way of attaining progress.
