1980s, Second term of office (1985–1989), Farewell Address (1989)
Context: The lesson of all this was, of course, that because we're a great nation, our challenges seem complex. It will always be this way. But as long as we remember our first principles and believe in ourselves, the future will always be ours. And something else we learned: Once you begin a great movement, there's no telling where it will end. We meant to change a nation, and instead, we changed a world.

People's Education interview (2007)
Context: All students are capable of growth. Some of them seem to be very slow to begin with and it’s probably not their fault, nor do I think it’s a matter of genetics. It’s a matter of what has happened in their lives before. They are all capable of growing, but they will not grow unless you interest them, captivate them in some way, and then make them reach out. Then they will finally enjoy reaching out.

The Liberals' Mistake (1987)
Context: What we need is a concept of "gross national cost." Life is a balance sheet, not simply economic growth. It is income and outgo. And until we know what the cost of growth is we will continue to operate under an illusion. As long as we consider only the growth of goods and ignore the growth of personal and community well-being, we will be impoverished by growth. That is what is happening in our society today.
