Concentrated power has always been the enemy of liberty.

We cannot escape our destiny, nor should we try to do so. The leadership of the free world was thrust upon us two centuries ago in that little hall of Philadelphia. In the days following World War II, when the economic strength and power of America was all that stood between the world and the return to the dark ages, Pope Pius XII said, 'The American people have a great genius for splendid and unselfish actions. Into the hands of America God has placed the destinies of an afflicted mankind.' We are indeed, and we are today, the last best hope of man on earth.

There seems to be an increasing awareness of something we Americans have known for some time - that the ten most dangerous words in the English language are "Hi, I'm from the government, and I'm here to help."

I am not a scientist.
