"Happiness comes from the full use of one's power to achieve excellence. Life is potentially an empty hole, and there are few more satisfying ways of filling it than achieving and exercising excellence. This principle of excellence is one which Americans seem to be losing, and at a time when the Nation stands in need of it. A lack of excellence implies mediocrity. And in a society that is willing to accept a standard of mediocrity, the opportunities for personal failure are boundless. Mediocrity can destroy us as surely as perils far more famous. It is important that we distinguish between what it means to fail at a task and what it means to be mediocre. There is all the difference in the world between the life lived with dignity and style which ends in failure, and one which achieves power and glory, yet is dull, unoriginal, unreflective, and mediocre. In a real sense, what matters is not so much whether we make a lot of money or hold a prestigious job; what matters is that we seek out others with knowledge and enthusiasm — that we become people who can enjoy our own company."

"The task of finding a purpose in life also calls for perseverance. I have seen many young men who rush out into the world with their messages, and when they find out how deaf the world is, they withdraw to wait and save their strength. They believe that after a while they will be able to get up on some little peak from which they can make themselves heard. Each thinks that in a few years he will have gained a standing, and then he can use his power for good. Finally the time comes, and with it a strange discovery: he has lost his horizon of thought. Without perseverance, ambition and a sense of responsibility have evaporated."

"The question of what we can do to give purpose or meaning to our lives has been debated for thousands of years by philosophers and common men. Yet today we seem, if anything, further from the answer than before. Despite our great material wealth and high standard of living, people are groping for something that money cannot buy. <!-- As Walter Lippman said: "Our life, though it is full of things, is empty of the kind of purpose and effort that gives to life its flavor and meaning.""

"Voltaire once said: "Not to be occupied and not to exist are one and the same thing for a man." With those few words he captured the essence of a purpose in life: to work, to create, to excel, and to be concerned about the world and its affairs."

"Some of the ideas I try to get across to the people who work for me are the following:"

"Yet it is incumbent on those in high places to make wise decisions and it is reasonable and important that the public be correctly informed. It is consequently incumbent on all of us to state the facts as forthrightly as possible."

"Unfortunately for those who must make far-reaching decisions without the benefit of an intimate knowledge of reactor technology, and unfortunately for the interested public, it is much easier to get the academic side of an issue than the practical side. For a large part those involved with the academic reactors have more inclination and time to present their ideas in reports and orally to those who will listen. Since they are innocently unaware of the real but hidden difficulties of their plans, they speak with great facility and confidence. Those involved with practical reactors, humbled by their experiences, speak less and worry more."

"The academic-reactor designer is a dilettante. He has not had to assume any real responsibility in connection with his projects. He is free to luxuriate in elegant ideas, the practical shortcomings of which can be relegated to the category of "mere technical details." The practical-reactor designer must live with these same technical details. Although recalcitrant and awkward, they must be solved and cannot be put off until tomorrow. Their solution requires manpower, time and money."

"The tools of the academic designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone sees it."

"An academic reactor or reactor plant almost always has the following basic characteristics: (1) It is simple. (2) It is small. (3) It is cheap. (4) It is light. (5) It can be built very quickly. (6) It is very flexible in purpose. (7) Very little development will be required. It will use off-the-shelf components. (8) The reactor is in the study phase. It is not being built now. On the other hand a practical reactor can be distinguished by the following characteristics: (1) It is being built now. (2) It is behind schedule. (3) It requires an immense amount of development on apparently trivial items. (4) It is very expensive. (5) It takes a long time to build because of its engineering development problems. (6) It is large. (7) It is heavy. (8) It is complicated."

"We were not prepared intellectually. Those of us in the national security field still carried the baggage of the Cold War. We thought in concepts of coalition warfare and the Warsaw Pact. When we thought of terrorism, we thought only of state-sponsored terrorism, which is why the immediate reaction of many in our government agencies after 9/11 was: Which state did it? Saddam, it must have been Saddam. We had failed to grasp, for a variety of reasons, the new phenomenon that had emerged in the world. This was not state-sponsored terrorism. This was religious war. .... This was the emergence of a transnational enemy driven by religious fervor and fanaticism. Our enemy is not terrorism. Our enemy is violent, Islamic fundamentalism."

"Many will recall with pain what we went through in the Reagan administration in 1983, when the Marine barracks were bombed in Beirut—241 Marines and Navy corpsmen were killed. We immediately got an intercept from NSA [National Security Agency], a total smoking gun from the foreign ministry of Iran, ordering the murder of our Marines. Nothing was done to retaliate. Instead, we did exactly what the terrorists wanted us to do, which was to withdraw. Osama bin Laden has cited this as one of his dawning moments."

"Power corrupts. Absolute power is kind of neat."

"I’d like to say we have fixed these problems, but we haven’t. We have very real vulnerabilities. We have not diminished in any way the fervor and ideology of our enemy. .... Today, probably 50 or more states have schools that are teaching jihad, preaching, recruiting, and training. We have absolutely no successful programs even begun to remediate against those efforts. .... Nobody paid attention. Presidents in four administrations put their arms around Saudi ambassadors, ignored the Wahhabi jihadism, and said these are our eternal friends."

"We are at a juncture today that really is more of a threshold, even more of a watershed, than the Japanese attack on Pearl Harbor was in 1941. We are currently in a war, but it is not a war on terrorism. In fact, that has been a great confusion, and the sooner we drop that term, the better. This would be like President Franklin Roosevelt saying in World War II, 'We are engaged in a war against kamikazes and blitzkrieg.' Like them, terrorism is a method, a tool, a weapon that has been used against us. And part of the reason we suffered such a horrific attack is that we were not prepared."
