“And here I cannot help mentioning a very ridiculous show of a learned pig, which of late days attracted much of the public notice, and at the polite end of the town. This pig, which indeed was a large unwieldy hog, being taught to pick up letters written upon pieces of cards, and to arrange them at command, gave great satisfaction to all who saw him, and filled his tormenter's pocket with money. One would not have thought that a hog had been an animal capable of learning: the fact, however, is another proof of what may be accomplished by assiduity; for the showman assured a friend of mine, that he had lost three very promising brutes in the course of training, and that the phenomenon then exhibited had often given him reason to despair of success.”

The Foundling and Other Tales of Prydain (1973)
Context: ... the book told him of other ways of the world; of cruelty, suffering, and death. He read of greed, hatred, and war; of men striving against one another with fire and sword; of the blossoming earth trampled underfoot, of harvests lost and lives cut short...
But now his heart lifted. These pages told not only of death, but of birth as well; how the earth turns in its own time and in its own way gives back what is given to it; how things lost may be found again; and how one day ends for another to begin. He learned that the lives of men are short and filled with pain, yet each one a priceless treasure, whether it be that of a prince or a pig-keeper. And, at the last, the book taught him that while nothing was certain, all was possible.

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.
