“Who can over estimate the progress of the world if all the money wasted in superstition could be used to enlighten, elevate and civilize mankind?”

Progress and Poverty (1879)
Context: I am no sentimental admirer of the savage state. I do not get my ideas of the untutored children of nature from Rousseau, or Chateaubriand, or Cooper. I am conscious of its material and mental poverty, and its low and narrow range. I believe that civilization is not only the natural destiny of man, but the enfranchisement, elevation, and refinement of all his powers, and think that it is only in such moods as may lead him to envy the cud — chewing cattle, that a man who is free to the advantages of civilization could look with regret upon the savage state. But, nevertheless, I think no one who will open his eyes to the facts can resist the conclusion that there are in the heart of our civilization large classes with whom the veriest savage could not afford to exchange. It is my deliberate opinion that if, standing on the threshold of being, one were given the choice of entering life as a Tierra del Fuegan, a black fellow of Australia, an Esquimau in the Arctic Circle, or among the lowest classes in such a highly civilized country as Great Britain, he would make infinitely the better choice in selecting the lot of the savage. For those classes who in the midst of wealth are condemned to want, suffer all the privations of the savage, without his sense of personal freedom; they are condemned to more than his narrowness and littleness, without opportunity for the growth of his rude virtues; if their horizon is wider, it is but to reveal blessings that they cannot enjoy.
There are some to whom this may seem like exaggeration, but it is only because they have never suffered themselves to realize the true condition of those classes upon whom the iron heel of modern civilization presses with full force. As De Tocqueville observes, in one of his letters to Mme. Swetchine, "we so soon become used to the thought of want that we do not feel that an evil which grows greater to the sufferer the longer it lasts becomes less to the observer by the very fact of its duration"; and perhaps the best proof of the justice of this observation is that in cities where there exists a pauper class and a criminal class, where young girls shiver as they sew for bread, and tattered and barefooted children make a home in the streets, money is regularly raised to send missionaries to the heathen! Send missionaries to the heathen! It would be laughable if it were not so sad. Baal no longer stretches forth his hideous, sloping arms; but in Christian lands mothers slay their infants for a burial fee! And I challenge the production from any authentic accounts of savage life of such descriptions of degradation as are to be found in official documents of highly civilized countries — in reports of sanitary commissioners and of inquiries into the condition of the laboring poor.

Vol 2, Ch. 25 "Has History any Meaning?" Variant: There is no history of mankind, there are only many histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world.
The Open Society and Its Enemies (1945)
Context: There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world. But this, I hold, is an offence against every decent conception of mankind. It is hardly better than to treat the history of embezzlement or of robbery or of poisoning as the history of mankind. For the history of power politics is nothing but the history of international crime and mass murder (including it is true, some of the attempts to suppress them). This history is taught in schools, and some of the greatest criminals are extolled as heroes.

1936
Context: There can be no such thing in the long run as the prosperity of an isolated nation... until the trade of the world once more begins to move from one country to another and goods can be exchanged and paid for— until that happens there is no permanency to the security we have gained. Does not that bring us back to this, that while we all know that we have got to go on, and go on quickly, with this matter of armaments, there is driven into us once more the mad folly of Europe to-day in the expenditure she is making on armaments at the sacrifice of her international trade? We have to do what we can in our conversations with foreign countries to show the folly of this, which, if protracted too long, may bring ruin to us all. Therefore we have still to hold on to the faith that sooner or later it may be possible once again to discuss the reduction of armaments. If and when that time comes we must all of us throw our weight into the effort. This massing of huge armaments on the Continent, even the work that we are doing— the money would be far better used for the progress of the world.

Letter 2
Letters Written in Sweden (1796)
Context: The more I see of the world, the more I am convinced that civilisation is a blessing not sufficiently estimated by those who have not traced its progress; for it not only refines our enjoyments, but produces a variety which enables us to retain the primitive delicacy of our sensations. Without the aid of the imagination all the pleasures of the senses must sink into grossness, unless continual novelty serve as a substitute for the imagination, which, being impossible, it was to this weariness, I suppose, that Solomon alluded when he declared that there was nothing new under the sun!

Progress, Coexistence and Intellectual Freedom (1968)
Context: Millions of people throughout the world are striving to put an end to poverty. They despise oppression, dogmatism, and demagogy (and their more extreme manifestations — racism, fascism, Stalinism, and Maoism). They believe in progress based on the use, under conditions of social justice and intellectual freedom, of all the positive experience accumulated by mankind.
