“Let no one misunderstand our idea; we do not confound what are called 'political opinions' with that grand aspiration after progress with that sublime patriotic, democratic, and human faith, which, in our days, should be the very foundation of all generous intelligence.”

“Why do we call all our generous ideas illusions, and the mean ones truths?”

“The conscious and intelligent manipulation of the organized habits and opinions of the masses is an important element in democratic society. Those who manipulate this unseen mechanism of society constitute an invisible government which is the true ruling power of our country. ...We are governed, our minds are molded, our tastes formed, our ideas suggested, largely by men we have never heard of. This is a logical result of the way in which our democratic society is organized. Vast numbers of human beings must cooperate in this manner if they are to live together as a smoothly functioning society. ...In almost every act of our daily lives, whether in the sphere of politics or business, in our social conduct or our ethical thinking, we are dominated by the relatively small number of persons...who understand the mental processes and social patterns of the masses. It is they who pull the wires which control the public mind.”

“Indeed, very few people are aware that in each of our fingers, located somewhere between the first phalange, the mesophalange, and the metaphalange, there is a tiny brain. The fact is that the other organ which we call the brain, the one with which we came into the world, the one which we transport around in our head and which transports us so that we can transport it, has only ever had very general, vague, diffuse and, above all, unimaginative ideas about what the hands and fingers should do. For example, if the brain-in-our-head suddenly gets an idea for a painting, a sculpture, a piece of music or literature, or a clay figurine, it simply sends a signal to that effect and then waits to see what will happen”

“The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there.”

“In these days of political, personal and economic disintegration, music is not a luxury, it's a necessity; not simply because it is therapeutic, nor because it is the universal language, but because it is the persistent focus of our intelligence, aspiration and goodwill.”
