The speaker acknowledges feeling intimidated by previous brilliant speakers and expresses gratitude for the awards received, emphasizing that reputation is what others think of you while character defines who you are. He highlights a contract with the audience: if anyone finishes their duty before he does, they should raise their hand to end his speech.
Understanding Service Through Metaphor and Altruism vs Self-Interest Service is illustrated through Wordsworth’s metaphor comparing it to morning dew protected by a daisy's shadow; true service occurs without recognition or reward. The speaker argues humanity’s greatest enemy lies within itself rather than external diseases like polio or AIDS, using 'man' generically for humankind. Economists have studied altruism versus self-interest in humans through experiments revealing conflicting findings about inherent kindness versus economic selfishness.
Challenging Economic Assumptions About Humanity John List challenged traditional economic theories on altruism by conducting real-life experiments showing people often act out of self-interest rather than generosity when not observed closely. Despite evidence supporting both sides regarding human nature—altruistic tendencies versus greed—the world seems increasingly troubled despite many organizations promoting goodness today. For deeper insights into these dynamics affecting society, he recommends reading "Super Freakonomics," which explores underlying issues shaping current realities.
