If anything, we older people yearn for a peaceful world even more than young people do. We are the ones who lost friends or relatives in some war. We are the ones who have lived a lifetime of seeing and reading about human suffering.

People confuse goodness with weakness. It is weak people, not good people (goodness demands strength), who are taken advantage of.

Nothing guarantees more the erosion of character than getting something for nothing

When I see the mostly young people of Occupy Wall Street - a mixture of the bored, the nihilistic, the seekers of excitement, the left-wing true believers, the confused idealists and those hoping to engage in violence - railing against the rich capitalists on Wall Street, I get worried. Because the hatred they express toward the rich is similar to that expressed against the rich by Stalin, Mao and Pol Pot. Of course, these people are not comparable to those killers. But class hatred must lead to bad things. That is why President Obama is playing with fire with his attacks on the rich.

Although images of perfection in people's personal lives can cause unhappiness, images of perfect societies - utopian images - can cause monstrous evil. In fact, forcefully changing society to conform to societal images was the greatest cause of evil in the twentieth century.

Even non-democratic allies no longer trust America. Barack Obama has alienated our most important and longest standing Arab allies, Egypt and Saudi Arabia. Both the anti-Muslim Brotherhood and the anti-Iran Arab states have lost respect for him.

I don't let the hate go to my heart, and I don't let the praise go to my head.
