Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.

I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit.

These are not dark days: these are great days - the greatest days our country has ever lived.

One of the greatest casualties of the war in Vietnam is the Great Society... shot down on the battlefield of Vietnam.

The greater the obstacle the more glory in overcoming it.

Greatness lies not in being strong but in the right using of strength and strength is not used rightly when it serves only to carry a man above his fellows for his own solitary glory. He is the greatest whose strength carries up the most hearts by the attraction of his own.

My opinion is the greatest reward that any government could get is the approval of the people. If the people are happy and the people are at peace and the government has done something for them that's the greatest reward I think any government could hope for.

I've got the greatest job in the world. There's no other job in government where cause and effect is so tightly coupled where you can make a difference every day in so many different ways and in so many different people's lives. It's a great challenge.

Religion flourishes in greater purity without than with the aid of Government.

What is government itself but the greatest of all reflections on human nature? If men were angels no government would be necessary. If angels were to govern men neither external nor internal controls on government would be necessary.

And I have no doubt that every new example will succeed as every past one has done in showing that religion and Government will both exist in greater purity the less they are mixed together.

I went to my son's graduation this weekend and I heard a great quote I've never heard before from Albert Einstein. It was that the greatest danger to the world is not the bad people but it's the good people who don't speak out.
