Nothing is so permanent as a temporary government program.

I'm not in favor of no government. You do need a government. But by doing so many things that the government has no business doing, it cannot do those things which it alone can do well. There's no other institution in my opinion that can provide us with protection of our life and liberty. However, the government performs that basic function poorly today, precisely because it is devoting too much of its efforts and spending too much of our income on things which are harmful. So I have no doubt that that's the major single problem we face.

Concentrated power is not rendered harmless by the good intentions of those who create it.

Anybody who was easily converted was not worth converting.

The proper role of government is exactly what John Stuart Mill said in the middle of the 19th century in "On Liberty." The proper role of government is to prevent other people from harming an individual. Government, he said, never has any right to interfere with an individual for that individual's own good.
