“Religions and states and classes and tribes and nations do not have to work or argue for their adherents and subjects. They more or less inherit them. Against this unearned patrimony there have always been speakers and writers who embody Einstein’s injunction to ‘remember your humanity and forget the rest.’ It would be immodest to claim membership in this fraternity/sorority, but I hope not to have done anything to outrage it. Despite the idiotic sneer that such principles are ‘fashionable,’ it is always the ideas of secularism, libertarianism, internationalism, and solidarity that stand in need of reaffirmation.”

“You could give Aristotle a tutorial. And you could thrill him to the core of his being. Aristotle was an encyclopedic polymath, an all time intellect. Yet not only can you know more than him about the world. You also can have a deeper understanding of how everything works. Such is the privilege of living after Newton, Darwin, Einstein, Planck, Watson, Crick and their colleagues.I’m not saying you’re more intelligent than Aristotle, or wiser. For all I know, Aristotle’s the cleverest person who ever lived. That’s not the point. The point is only that science is cumulative, and we live later.”

“I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.”

“If it’s true what is said, that only the wise discover the wise, then it must also be true that the lone wolf symbolizes either the biggest fool on the planet or the biggest Einstein on the planet.”

“Anyone who doesn’t take truth seriously in small matters cannot be trusted in large ones either.”

“Although I am a typical loner in my daily life, my awareness of belonging to the invisible community of those who strive for truth, beauty, and justice has prevented me from feelings of isolation.”
