“Our colleges ought to have lit up in us a lasting relish for the better kind of man, a loss of appetite for mediocrities, and a disgust for cheapjacks. We ought to smell, as it were, the difference of quality in men and their proposals when we enter the world of affairs about us.”

Variant: and it ought to make us feel ashamed when we talk like we know what we're talking about when we talk about love.

Context: !-- I want to talk to my fellow Americans a little more, if I may: --> My fellow Americans. No association ever mattered more to me. We’re not always right. We’re impetuous and impatient, and rush into things without knowing what we’re really doing. We argue over little differences endlessly, and exaggerate them into lasting breaches. We can be selfish, and quick sometimes to shift the blame for our mistakes to others. But our country ‘tis of thee.‘ What great good we’ve done in the world, so much more good than harm. We served ourselves, of course, but we helped make others free, safe and prosperous because we weren’t threatened by other people’s liberty and success. We need each other. We need friends in the world, and they need us. The bell tolls for us, my friends, Humanity counts on us, and we ought to take measured pride in that. We have not been an island. We were ‘involved in mankind.‘
Before I leave, I’d like to see our politics begin to return to the purposes and practices that distinguish our history from the history of other nations. I would like to see us recover our sense that we are more alike than different. We are citizens of a republic made of shared ideals forged in a new world to replace the tribal enmities that tormented the old one. Even in times of political turmoil such as these, we share that awesome heritage and the responsibility to embrace it. Whether we think each other right or wrong in our views on the issues of the day, we owe each other our respect, as long as our character merits respect, and as long as we share, for all our differences, for all the rancorous debates that enliven and sometimes demean our politics, a mutual devotion to the ideals our nation was conceived to uphold, that all are created equal, and liberty and equal justice are the natural rights of all. Those rights inhabit the human heart, and from there, though they may be assailed, they can never be wrenched. I want to urge Americans, for as long as I can, to remember that this shared devotion to human rights is our truest heritage and our most important loyalty.

On se doit assemer en robes et en armes en tel manière que li preudome de cest siècle ne dient que on en face trop, ne les joenes gens de cest siècle ne dient que on en face peu.

Context: Let us rise up tonight with a greater readiness. Let us stand with a greater determination. And let us move on in these powerful days, these days of challenge to make America what it ought to be. We have an opportunity to make America a better nation. And I want to thank God, once more, for allowing me to be here with you.
