In this statement following the assassination of Martin Luther King Jr., Kennedy uses the quote to propose a way in which the world can be kinder and more gentle. Before he presented the quote, he introduced it in the following way:
<em>"Let us dedicate ourselves to what the Greeks wrote so many years ago: to tame the savageness of man and make gentle the life of this world."</em>
The introduction that Kennedy provides of his quote shows that he obtained this quote from the Greeks.
A public good is a good that doesn't cause rivalry and doesn't exclude anyone and anyone is using it for the good of the society. An examples of a public goods might be fresh air or national security.
