“There is nothing you can do that profit does not enter into, and fear of loss, and wish for power. You cannot say good morning without knowing which of you is 'superior' to the other, or trying to prove it. You cannot act like a brother to other people, you must manipulate them, or command them, or obey them, or trick them. You cannot touch another person, yet they will not leave you alone. There is no freedom.”

“There are some people that you cannot change, you must either deal with them or leave them alone.”

“Another person is, at the heart of it, unknowable. And if you cannot know a person enough to always guess what they’re capable of, you certainly cannot know them enough to hold them in your hands, to control their behavior, to fight, manipulate, cajole or nurse or soothe them into doing what they should or shouldn’t.People will do what they will do. The trick is admitting your own helplessness about that little fact.”

“Be not angry that you cannot make others as you wish them to be, since you cannot make yourself as you wish to be.”

“Do you not think that there are things which you cannot understand, and yet which are; that some people see things that others cannot? But there are things old and new which must not be contemplate by men´s eyes, because they know -or think they know- some things which other men have told them. Ah, it is the fault of our science that it wants to explain all; and if it explain not, then it says there is nothing to explain.”

“You cannot drive people to do things which are right, but you can love them into doing them, if your example is of such a character that they can see you mean what you say.”
