You cannot simultaneously have free immigration and a welfare state.

We have a freer world because of the collapse of the Soviet Union and the changes in China. Those two have been the main contributors to freedom in our time.

The free man will ask neither what his country can do for him nor what he can do for his country. He will ask rather 'What can I and my compatriots do through government' to help us discharge our individual responsibilities, to achieve our several goals and purposes, and above all, to protect our freedom?

The most unresolved problem of the day is precisely the problem that concerned the founders of this nation: how to limit the scope and power of government. Tyranny, restrictions on human freedom, come primarily from governmental restrictions that we ourselves have set up.

How do you hold down government spending?

The only relevant test of the validity of a hypothesis is comparison of prediction with experience.

You never have real changes unless you have a time of crisis.
