Answer: First, specific evidence for sacrificing oneself for the greater good of humanity comes directly from John F. Kennedy's inaugural address. In this speech he say's "Ask not what your country can do for you, but what you can do for your country". He gave this speech on January 20, 1961 in Washington. This is him trying to convince the American people to do great things that will impact the country as a whole, like join the military. His argument is very convincing because it put hope in the American people's heart and made everyone check themselves. After winning the presidential election and giving his inaugural address, most Americans supported Kennedy and he was able to get a high approval rate. This argument is very convincing because the people knew that these words coming from Kennedy were genuine. In today's world his request is being fulfilled because we have a rise in police employments, more military personnel joining, and just more pride in the country.
The argument made by President Kennedy's Inaugural Address brings up more than once of one sacrificing them self for the greater good of humanity. It is a good and convincing argument as the way he puts it because it talks about how all kinds of sacrifices made for the continuing success of freedom and liberty. Reasoning to support that claim can be seen here from the Inaugural Address of John F. Kennedy himself , JFK states , "Let every nation know , whether it wishes us well or ill , that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and success of liberty." As it can be concluded by reading the mentioned quote from Kennedy's Inaugural Address , that is a message and argument to any nation who wants to oppose the freedom and liberty of the United States or its allies that any sacrifice will be made to prevent the downfall of the Country's freedom and its allies as well. The legacy of his request is now a common duty and legacy as many people every single day do certain jobs and sacrifices for the well being of humanity.
