“This world has few redeeming features, and one is the capacity for people to love one another with great, enduring passion.”

Letter to the Lenape Nation (18 October 1681); as published in William Penn and the Founding of Pennsylvania 1680 - 1684: A Documentary History, (1983) edited by Jean R. Soderlund, University of Pennsylvania Press
Context: There is one great God and power that has made the world and all things therein, to whom you and I and all people owe their being and well-being, and to whom you and I must one day give an account for all that we do in this world. This great God has written his law in our hearts, by which we are taught and commanded to love and help and do good to one another, and not to do harm and mischief one unto another. Now this great God has been pleased to make me concerned in your parts of the world, and the king of the country where I live has given unto me a great province therein, but I desire to enjoy it with your friends, else what would the great God say to us, who has made us not to devour and destroy one another, but live soberly and kindly together in the world.
Now I would have you well observe, that I am very sensible of the unkindness and injustice that has been too much exercised towards you by the people of these parts of the world, who have sought themselves, and to make great advantages by you, rather than be examples of justice and goodness unto you; which I hear has been matter of trouble to you and caused great grudgings and animosities, sometimes to the shedding of blood, which has made the great god angry. But I am not such man as is well known in my own country. I have great love and regard toward you, and I desire to win and gain your love and friendship by a kind just, and peaceable life; and the people I send are of the same mind, and shall in all things behave themselves accordingly.

Context: We arrived within 11 miles of our old One Ton Camp with fuel for one hot meal and food for two days. For four days we have been unable to leave the tent - the gale howling about us. We are weak, writing is difficult, but for my own sake I do not regret this journey, which has shown that Englishmen can endure hardships, help one another, and meet death with as great a fortitude as ever in the past. We took risks, we knew we took them; things have come out against us, and therefore we have no cause for complaint, but bow to the will of Providence, determined still to do our best to the last.

Innokenty, in Ch. 57.
Variant translation: For a country to have a great writer is like having a second government. That is why no regime has ever loved great writers, only minor ones.

Context: The pursuit of perfection, then, is the pursuit of sweetness and light. He who works for sweetness and light, works to make reason and the will of God prevail. He who works for machinery, he who works for hatred, works only for confusion. Culture looks beyond machinery, culture hates hatred; culture has one great passion, the passion for sweetness and light.

Context: For, when you are approaching poverty, you make one discovery which outweighs some of the others. You discover boredom and mean complications and the beginnings of hunger, but you also discover the great redeeming feature of poverty: the fact that it annihilates the future. Within certain limits, it is actually true that the less money you have, the less you worry. When you have a hundred francs in the world you are liable to the most craven panics. When you have only three francs you are quite indifferent; for three francs will feed you till tomorrow, and you cannot think further than that. You are bored, but you are not afraid. You think vaguely, 'I shall be starving in a day or two--shocking, isn't it?' And then the mind wanders to other topics. A bread and margarine diet does, to some extent, provide its own anodyne. And there is another feeling that is a great consolation in poverty. I believe everyone who has been hard up has experienced it. It is a feeling of relief, almost of pleasure, at knowing yourself at last genuinely down and out. You have talked so often of going to the dogs--and well, here are the dogs, and you have reached them, and you can stand it. It takes off a lot of anxiety.
