We know that the Zanj (blacks) are the least intelligent and the least discerning of mankind, and the least capable of understanding the consequences of actions.

You know, in physics there's the old law for every action there's a equal amount of reaction. Sometimes that's true in politics. If somebody's out there making nonsensical statements, but wielding power behind them a lot of people say, "Well, I need to react to that." I think that's happening.

Knowledge without action is wastefulness and action without knowledge is foolishness.

The United States only knows one form of intervention and that is the military one. Everything depends on drawn weapons. We should, however, develop a wider scope of action. And we should learn to be patient.

We can't be naive and think we can go it alone; we must humble ourselves and commit to routine and collective actions. This is just one reason why I am thrilled to be working with the UN Environment as its Goodwill Ambassador.

Find a partner, commit to taking action, and hold each other accountable. Helping our planet is not a one-person or one-country job; we need to be good partners and good neighbors to one another. Routine, measurable, and collective actions both small and large will make an impact.

We don't tolerate terrorism. We go after the terrorists and those who support them and those who justify their actions.

Leadership requires using power to influence the thoughts and actions of other people.

As our case is new, so we must think anew, and act anew.

How often it is that a small action becomes great by its intention. And how often it is that a great action becomes small by its intention.
