John F. Kennedy's quote reflects on the idea that if extraterrestrial life exists, it may have reached a level of scientific advancement that surpasses our own, rendering deep space exploration futile.

I am not, in the ordinary acceptation of the term, a good-natured man; that is, many things annoy me besides what interferes with my own ease and interest.

He was a worshiper of liberty, a friend of the oppressed. A thousand times I have heard him quote these words: 'For Justice all place a temple, and all season, summer.' He believed that happiness is the only good, reason the only torch, justice the only worship, humanity the only religion, and love the only priest.
