“My profession often gets bad press for a variety of sins, both actual and imagined: arrogance, venality, insensitivity to moral issues about the use of knowledge, pandering to sources of funding with insufficient worry about attendant degradation of values. As an advocate for science, I plead “mildly guilty now and then” to all these charges. Scientists are human beings subject to all the foibles and temptations of ordinary life. Some of us are moral rocks; others are reeds. I like to think (though I have no proof) that we are better, on average, than members of many other callings on a variety of issues central to the practice of good science: willingness to alter received opinion in the face of uncomfortable data, dedication to discovering and publicizing our best and most honest account of nature's factuality, judgment of colleagues on the might of their ideas rather than the power of their positions.”

“Increasingly, politics is not about "who gets what, when, how" but about values, each of them considered to be absolute. Politics is about "the right to life"…It is about the environment. It is about gaining equality for groups alleged to be oppressed…None of these issues is economic. All are fundamentally moral.”

“I believe that the goal of life is to create community, to bring us together in love and compassion—to understand that it is my moral obligation to be concerned about your family, and yours to be concerned about mine. As human beings, we are in this together.”

“We shouldn't take information tranquilizers. Because sometimes information is spread about some moral and psychological breakdown in the Ukrainian armed forces, which are allegedly on the verge of some kind of crisis in moral and so on. All of that, to put it mildly, is false.”

“All moral doctrine, all practical suggestions about how we ought to live, depend on some belief about what human nature is like.”

“Do not let us imagine that discoveries in the world of the higher mathematics, of physics or biology are going to remove or even reduce our difficulties on the moral plane…The realm of morals is a world neither of quantity nor of chemical action. It is a world of values. It is precisely these values of right and wrong, of good and evil, of honesty and courage, which matter supremely for religion and national life…I am not despising science. I am only suggesting that moral values, eternal in their quality, transient in their form and application, are the foundation of a country's greatness. If moral values flourish in our common life all will be well with the nation.”

“Individual human beings are all tools, that the others use to help us all survive.” “That’s a lie.” “No. It’s just a half truth. You can worry about the other half after we win this war.”

“In many cases, humans think themselves as the culmination of all knowledge. In fact, more things we don't know about ourselves. Without knowledge of the source of that truth, humans cannot exist. Humans have no value.”

“If speaking to nonscientific audiences is something that interests you or will likely be asked of you, keep in mind three overriding requirements: first, you must be a human being, an interesting one if at all possible; second, you must be accurate in what you say, that is, tell the truth (about what is known and what isn't; about issues, debates, controversies); and third, if your subject is scientific knowledge, you must remain a scientist and not slip into the role of advocate or activist.”

“Sex. Some of us do it, most of us like it and we all think about it…. A lot. I know I do (though I was told that it’s normal). Gettin’ busy really isn’t the taboo subject that it once was.”
