“Science is imagination in the service of the verifiable truth, and tha...” — Gerald Edelman Quote

“Science is imagination in the service of the verifiable truth, and that service is indeed communal. It cannot be rigidly planned. Rather, it requires freedom and courage and the plural contributions of many different kinds of people who must maintain their individuality while giving to the group.”

“The computer is not, in our opinion, a good model of the mind, but it is as the trumpet is to the orchestra - you really need it. And so, we have very massive simulations in computers because the problem is, of course, very complex.”

“Consciousness allows you the capacity to plan.”

“Each brain is exposed to different circumstances. It's very likely that your brain is unique in the history of the universe.”

“Many cognitive psychologists see the brain as a computer. But every single brain is absolutely individual, both in its development and in the way it encounters the world.”

“Your brain develops depending on your individual history. What has gone on in your own brain and its consciousness over your lifetime is not repeatable, ever - not with identical twins, not even with conjoined twins.”

“It's very difficult to escape your background. You know, I don't think it's necessary to even try to escape it. More and more, I start to think that it's necessary to see exactly what it is that you inherited on both ends of the stick: your timidity, your courage, your self-deceit, and your honesty - and all the rest of it.”

“Daring to set boundaries is about having the courage to love ourselves, even when we risk disappointing others.”

“There's only one requirement of any of us, and that is to be courageous. Because courage, as you might know, defines all other human behavior. And, I believe - because I've done a little of this myself - pretending to be courageous is just as good as the real thing.”

“I have reached the conclusion that those who have physical courage also have moral courage. Physical courage is a great test.”

“Scientists tend to come in two stripes: those who have tremendous appetite and aptitude for the details, and those who illuminate the big picture. Sagan was definitely in the latter category, and he was profoundly good at it. He made connections that others did not have the intellectual breadth or courage to make.”
