“Tyrannical towards himself, he must be tyrannical towards others. All the gentle and enervating sentiments of kind ship, love, friendship, gratitude and even honor must be suppressed in him and give place to the cold and single minded passion for revolution.”

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.

“Confusing ‘Character’ with ‘Temperament’”
Clearing the Ground (1986)
Context: The core in the mystery of what we call personality resides in the individual mix between character and temperament. The most successful personalities are those who achieve the best balance between the strict demands of character and the lenient tolerance of temperament. This balance is the supreme test of genuine leadership, separating the savior from the fanatic.
The human Jesus is, to my mind, the ultimate paradigm of such psychic equilibrium. He was absolutely hard on himself and absolutely tender toward others. He maintained the highest criteria of conduct for himself but was not priggish or censorious or self-righteous about those who were weaker and frailer. Most persons of strength cannot accept or tolerate weakness in others. They are blind to the virtues they do not possess themselves and are fiercely judgmental on one scale of values alone. Jesus was unique, even among religious leaders, in combining the utmost of principle with the utmost of compassion for those unable to meet his standards.
We need to understand temperament better than we do and to recognize its symbiotic relationship to character. There are some things people can do to change and some things they cannot do — character can be formed, but temperament is given. And the strong who cannot bend are just as much to be pitied as the weak who cannot stiffen.
