“Among all the many great transitions that have marked the evolution of Western civilisation ... there has been only one—the triumph of Christianity —that can be called in the fullest sense a "revolution": a truly massive and epochal revision of humanity's prevailing vision of reality, so pervasive in its influence and so vast in its consequences as to actually have created a new conception of the world, of history, of human nature, of time, and of the moral good.”

“The bourgeois period of history has to create the material basis of the new world — on the one hand universal intercourse founded upon the mutual dependency of mankind, and the means of that intercourse; on the other hand the development of the productive powers of man and the transformation of material production into a scientific domination of natural agencies. Bourgeois industry and commerce create these material conditions of a new world in the same way as geological revolutions have created the surface of the earth. When a great social revolution shall have mastered the results of the bourgeois epoch, the market of the world and the modern powers of production, and subjected them to the common control of the most advanced peoples, then only will human progress cease to resemble that hideous, pagan idol, who would not drink the nectar but from the skulls of the slain.”

“One of the most unique aspects among many about the USA is that our transitions of 'power' have almost always been peaceful. This is very unique in all of history and in the world today".”

“The mutual-aid tendency in man has so remote an origin, and is so deeply interwoven with all the past evolution of the human race, that is has been maintained by mankind up to the present time, notwithstanding all vicissitudes of history.”

“I've been surprised by how many of you actually seem to believe that what you have is perfection. [...] A great many of you consciously or unconsciously think of evolution as a process of inexorable improvement. You imagine that humans began as a completely miserable lot but under the influence of evolution very gradually got better and better and better and better until one day the became what you are now, complete with frost-free refrigerators, microwave ovens, air-conditioning, minivans, and satellite telivision with six hundred channels. [...] In its root sense, 'wealth' isn't a synonym for 'money', it's a synonym for 'wellness'.”

“If you want to say something truly new, you must first know everything that has been said in the human history; not half, not ninety percent, but all that has been said! Only then you can say something new, if you can!”
