"The mystery of consciousness remains the central problem of biology."

"What is the use of having developed a science well enough to make predictions if, in the end, all we have to say is 'I don't know'?"

"Progress in science depends on new techniques, new discoveries, and new ways of thinking."

"The first principle is that you must not fool yourself, and you are the easiest person to fool."

"One cannot be deeply responsive to the world without being saddened very often."

"To persist in trying to solve a problem is the first step towards mastery."

"The beauty of science is that it explains the natural world in simple, elegant terms."

"To understand life we must understand the nature of biological information."

"Our neurons are dying all the time, and being replaced, in fact most of the neurons are replaced."
