Final answer:
Mark Twain expands Jerry's definition of 'corn-pone opinions' by outlining the human tendency to conform and imitate society in forming beliefs. Numbering his points creates a structured and persuasive argument about the origins of personal opinions.
Step-by-step explanation:
In Mark Twain's discussions of corn-pone opinions, he expands on Jerry's definition by delineating the ways human behavior and beliefs are mostly adopted from others rather than self-derived. Twain begins to elaborate on this by numbering two main points, emphasizing the influence of societal conformity and the inherent human instinct to imitate. The effect of numbering these points is to provide a clear, structured expansion of the concept, thus making the argument more digestible and persuasive. By dissecting the human propensity for imitation and the unconscious submission to the dictates of society, Twain sheds light on the psychology behind opinions and how rarely they may be truly original or personal.
