“In its broad sense, civilization means not only comfort in daily necessities but also the refining of knowledge and the cultivation of virtue so as to elevate human life to a higher plane”

1930s, Mein Weltbild (My World-view) (1931)
Context: In human freedom in the philosophical sense I am definitely a disbeliever. Everybody acts not only under external compulsion but also in accordance with inner necessity. Schopenhauer's saying, that "a man can do as he will, but not will as he will," has been an inspiration to me since my youth up, and a continual consolation and unfailing well-spring of patience in the face of the hardships of life, my own and others'. This feeling mercifully mitigates the sense of responsibility which so easily becomes paralyzing, and it prevents us from taking ourselves and other people too seriously; it conduces to a view of life in which humor, above all, has its due place.

1920s, Toleration and Liberalism (1925)
Context: The generally expressed desire of 'America first' can not be criticized. It is a perfectly correct aspiration for our people to cherish. But the problem which we have to solve is how to make America first. It can not be done by the cultivation of national bigotry, arrogance, or selfishness. Hatreds, jealousies, and suspicions will not be productive of any benefits in this direction. Here again we must apply the rule of toleration. Because there are other peoples whose ways are not our ways, and whose thoughts are not our thoughts, we are not warranted in drawing the conclusion that they are adding nothing to the sum of civilization. We can make little contribution to the welfare of humanity on the theory that we are a superior people and all others are an inferior people. We do not need to be too loud in the assertion of our own righteousness. It is true that we live under most favorable circumstances. But before we come to the final and irrevocable decision that we are better than everybody else we need to consider what we might do if we had their provocations and their difficulties. We are not likely to improve our own condition or help humanity very much until we come to the sympathetic understanding that human nature is about the same everywhere, that it is rather evenly distributed over the surface of the earth, and that we are all united in a common brotherhood. We can only make America first in the true sense which that means by cultivating a spirit of friendship and good will, by the exercise of the virtues of patience and forbearance, by being 'plenteous in mercy', and through progress at home and helpfulness abroad standing as an example of real service to humanity.

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.

The Poetic Principle (1850)
Context: I hold that a long poem does not exist. I maintain that the phrase, "a long poem," is simply a flat contradiction in terms.
I need scarcely observe that a poem deserves its title only inasmuch as it excites, by elevating the soul. The value of the poem is in the ratio of this elevating excitement. But all excitements are, through a psychal necessity, transient. That degree of excitement which would entitle a poem to be so called at all, cannot be sustained throughout a composition of any great length.

Maurice in “Characters,” p. 298
Pretexts: Reflections on Literature and Morality (1964)
Context: In my present insistence on high standards you will see that there is less self-indulgence than resolve and application. I do not let the Christian monopolize the ideal of perfection. I have my own virtue, which I am constantly cultivating and refining by teaching myself not to tolerate in me or my surroundings anything but the exquisite.
