One of our greatest assets is that all men aspire to be equal and free. This fact haunts the rulers of the Kremlin today for even they cannot change this law of nature and they know it. It is up to us, not only by example but by positive acts, to make the most of this driving force within mankind.

It's a wonderful story for the gun lobby to tell that if you just load up schools with weapons, you'll be safer. All of the evidence suggests that homes and communities that have more weapons have more gun crimes, not less.

Overly simplistic suggestions that we ban people from entering this country, based on religion, or ban people from an entire region of the world is counterproductive. It will not work. We need to build bridges to communities, to American-Muslim communities right now, to encourage them to help us in our homeland security efforts.

I hope corporations will dedicate a percentage of their top innovators' time to issues that could help people left out of the global economy. This kind of contribution is even more powerful than giving cash or offering employees' time off to volunteer. It is a focused use of what your company does best. It is a great form of creative capitalism, because it takes the brainpower and makes life better for the richest, and dedicates some of it to improving the lives of everyone else.

Not to find one's way around a city does not mean much. But to lose one's way in a city, as one loses one's way in a forest, requires some schooling. Street names must speak to the urban wanderer like the snapping of dry twigs, and little streets in the heart of the city must reflect the times of day, for him, as clearly as a mountain valley. This art I acquired rather late in life; it fulfilled a dream, of which the first traces were labyrinths on the blotting papers in my school notebooks.

They that know no evil will suspect none.
