“There are no clear reasons, and I am not going to make one up, to explain the recent strengthening of Epsilon.”

Saint's Progress (1919)
Context: "I cannot explain. There are things that I can't make clear, because you are wilfully blind to all that I believe in. For what do you imagine we are fighting this great war, if it is not to reestablish the belief in love as the guiding principle of life?"
Laird shook his head. "We are fighting to redress a balance, which was in danger of being lost."
"The balance of power?"
"Heavens! — no! The balance of philosophy."
Pierson smiled. "That sounds very clever, George; but again, I don't follow you."
"The balance between the sayings: 'Might is Right,' and 'Right is Might.' They're both half-truth, but the first was beating the other out of the field. All the rest of it is cant, you know. And by the way, sir, your Church is solid for punishment of the evildoer. Where's mercy there? Either its God is not merciful, or else it doesn't believe in its God.

Context: Explanations are clear but since no one to whom a thing is explained can connect the explanations with what is really clear, therefore clear explanations are not clear. Now this is a simple thing that anybody who has ever argued or quarreled knows perfectly well is a simple thing, only when they read it they do not understand it because they do not see that understanding and believing are not the same thing.

Alan Watts, on Zen (2015) https://www.youtube.com/watch?v=eh-3FJs2pz8
Context: I want to make one thing absolutely clear. I am not a Zen Buddhist, I am not advocating Zen Buddhism, I am not trying to convert anyone to it. I have nothing to sell. I'm an entertainer. That is to say, in the same sense, that when you go to a concert and you listen to someone play Mozart, he has nothing to sell except the sound of the music. He doesn’t want to convert you to anything. He doesn’t want you to join an organization in favor of Mozart's music as opposed to, say, Beethoven's. And I approach you in the same spirit as a musician with his piano or a violinist with his violin. I just want you to enjoy a point of view that I enjoy.

Je ne vois qu'une règle: être clair. Si je ne suis pas clair, tout mon monde est anéanti.
