I came into the Agency with a set of ideas and attitudes that were quite typical of people coming into the Agency at that time. You could call it liberal anti-communism.

An espionage organization is a collector: it collects raw information. That gets processed by a machinery that is supposed to resolve its reliability, and to present a finished product.

The national security state has many unfair and cruel weapons in its arsenal, but that of junk science is one which can be fought and perhaps defeated.

I said in court a long time ago that I didn't see that the Soviet Union was significantly helped by the information I gave them, nor that the United States was significantly harmed.

The human spy, in terms of the American espionage effort, had never been terribly pertinent.

The use of the polygraph has done little more than create confusion, ambiguity and mistakes.

By the late '70s I had come to question the point of a great deal of what we were doing, in terms of the CIA's overall charter.

When Reagan was elected, I felt that the Agency had gone much more into the service of a political tendency in the country with which I had already felt very strong disagreement.

Espionage, for the most part, involves finding a person who knows something or has something that you can induce them secretly to give to you. That almost always involves a betrayal of trust.

When I got the money, the whole burden descended on me, and the realization of what I had done. And it led me then to make the further step, a change of loyalties.

Because interrogations are intended to coerce confessions, interrogators feel themselves justified in using their coercive means. Consistency regarding the technique is not important; inducing anxiety and fear is the point.

The only thing I ever withheld from the KGB were the names of two agents whom I personally had known and handled and had a particular feeling for.

The Soviet Union did not achieve victory over the West, so was my information inadequate to help them to victory, or did it play no particular role in their failure to achieve victory?

I handed over names and compromised so many CIA agents in the Soviet Union.

In my professional work with the Agency, by the late '70s, I had come to question the value of a great deal of what we were doing, in terms of the intelligence agency's impact on American policy.

I could have stopped it after they paid me the $50,000. I wouldn't even have had to go on to do more than I already had: just the double agents' names that I gave.

The resistance of policy-makers to intelligence is not just founded on an ideological presupposition. They distrust intelligence sources and intelligence officials because they don't understand what the real problems are.

Perhaps my information hurt the Soviet Union more than it helped. I have no idea. It was not something I ever discussed with the KGB officers that I was dealing with.

Foreign Ministry guys don't become agents. Party officials, the Foreign Ministry nerds, tend not to volunteer to Western intelligence agencies.

The betrayal of trust carries a heavy taboo.

Deciding whether to trust or credit a person is always an uncertain task.

When I handed over the names and compromised so many CIA agents in the Soviet Union, I had come to the conclusion that the loss of these sources to the U.S. would not compromise significant national defense, political, diplomatic interests.

I found that our Soviet espionage efforts had virtually never, or had very seldom, produced any worthwhile political or economic intelligence on the Soviet Union.

I'm a traitor, but I don't consider myself a traitor.

Our Soviet espionage efforts had virtually never, or had very seldom, produced any worthwhile political or economic intelligence on the Soviet Union.

My little scam in April '85 went like this: Give me $50,000; here's some names of some people we've recruited.

We had periodic crises in this country when the technical intelligence didn't support the policy. We had the bomber gap, the missile gap.

You might as well ask why a middle-aged man with no criminal record might put a paper bag over his head and rob a bank. I acted out of personal desperation.

The difficulties of conducting espionage against the Soviet Union in the Soviet Union were such that historically the Agency had backed away from the task.

The U.S. is, so far as I know, the only nation which places such extensive reliance on the polygraph. It has gotten us into a lot of trouble.

There are so many things a large intelligence espionage organization can do to justify its existence, that people can get promotions for, because it could result in results.

I knew quite well, when I gave the names of our agents in the Soviet Union, that I was exposing them to the full machinery of counterespionage and the law, and then prosecution and capital punishment.

I saw a limit to what I was giving as kind of a scam I was running on the KGB, by giving them people that I knew were their double agents fed to us.

To the extent that I considered the personal burden of harming the people who had trusted me, plus the Agency, or the United States, I wasn't processing that.

No one's interested really in knowing what policies or diplomatic initiatives or arms negotiations might have been compromised by me.

The FBI, to its credit in a self-serving sort of way, rejects the routine use of the polygraph on its own people.

Historians don't really like to carry on speculative debates, but you could certainly argue that the likelihood of a Soviet invasion of Western Europe was extremely, extremely low.

Let's say a Soviet exchange student back in the '70s would go back and tell the KGB about people and places and things that he'd seen and done and been involved with. This is not really espionage; there's no betrayal of trust.

The multiplicity of ideas is what I'm interested in.

Ideas are easy. It's the execution of ideas that really separates the sheep from the goats.

Generally students are the best vehicles for passing on ideas, for their thoughts are plastic and can be molded and they can adjust the ideas of old men to the shape of reality as they find it in villages and hills of China or in ghettos and suburbs of America.

In the past 3-4 years I've developed a habit of keeping numerous small cassette recorders in my house and in a bag with me so that I'm able to commit to tape memory song ideas on a constant basis.

Many ideas grow better when transplanted into another mind than in the one where they sprung up.

Land began to be seen as something to be owned privately and exploited for private interests, and never was entirely reconciled with the old ideas that land should be utilized in common for the good of all.

Simple ideas lie within the reach only of complex minds.

While a lab Director can get done the things that he regards as important, he has the more important job of bringing out the best ideas of the broader scientific community.

I think a good MP is someone who cares for their community and becomes their champion, which is why I will make my home in any seat I am lucky enough to be selected for. Looks play no part in the equation, what matters is your ideas and connecting them to the electorate.

The test of a first-rate intelligence is the ability to hold two opposed ideas in mind at the same time and still retain the ability to function.
