Antonio: One can live a life of moderation by never deviating from the middle course. But then one loses the joy of spontaneity and misses the opportunities that come to those who are occasionally willing to take great chances, or to go too far. Marla: But one who, in the interests of moderation, never risks going too far is actually failing to live a life of moderation: one must be moderate even in one' s moderation. Antonio and Marla disagree over ['what a life of moderation requires of a person', 'how often a person ought to deviate from the middle course in life', 'whether it is possible for a person to embrace other virtues along with moderation', 'whether it is desirable for people to be moderately spontaneous']
