Every one interprets everything in terms of his own experience. If you say anything which does not touch a precisely similar spot in another man's brain, he either misunderstands you, or doesn't understand you at all.

I remember a conversation which we had once about translating. Hugo knew nothing about translating, but when he learnt that I was a translator he wanted to know what it was like. I remember him going on and on, asking questions such as: What do you mean when you say that you think the meaning in French? How do you know you’re thinking it in French? If you see a picture in your mind how do you know it’s a French picture? Or is it that you say the French word to yourself? What do you see when you see that the translation is exactly right? Are you imagining what someone else would think, seeing it for the first time? Or is it a kind of feeling? What kind of feeling? Can’t you describe it more closely? And so on and so on, with a fantastic patience. This sometimes became very exasperating. What seemed to me to be the simplest utterance soon became, under the repeated pressure of Hugo’s ‘You mean’, a dark and confused saying of which I no longer myself knew the meaning. The activity of translating, which had seemed the plainest thing in the world, turned out to be an act so complex and extraordinary that it was puzzling to see how any human being could perform it.

I had come this far without the elegance of speech. ... I could not speak coherently. I stuttered in my mind. I could not express my perception of the sacred. I could speak everyday language: Please pass the salt. I would like . . . When are we going . . . I'll meet you there. I wanted the intricate and metaphorical language of my ancestors to pass through my language, my life.

all the suffering that humanity ever knew can be traced to the one fact that no man in the history of the Galaxy, until Hari Seldon, and very few men thereafter, could really understand one another. Every human being lived behind an impenetrable wall of choking mist within which no other but he existed. Occasionally there were the dim signals from deep within the cavern in which another man was located - so that each might grope toward the other. Yet because they did not know one another, and could not understand one another, and dared not trust one another, and felt from infancy the terrors and insecurity of that ultimate isolation - there was the hunted fear of man for man, the savage rapacity of man toward man.

JOHN: I’ll tell you a story about myself. Do you mind? I was raised to think myself stupid. That’s what I want to tell you.

CAROL: What do you mean?

JOHN: Just what I said. I was brought up, and my earliest, and most persistent memories are of being told that I was stupid. “You have such intelligence. Why must you behave so stupidly?” Or, “Can’t you understand? Can’t you understand?” And I could not understand. I could not understand.

CAROL: What?

JOHN: The simplest problem. Was beyond me. It was a mystery.

CAROL: What was a mystery?

JOHN: How people learn. How I could learn. Which is what I’ve been speaking of in class. And of course, you can’t hear it. Carol. Of course, you can’t. (Pause) I used to speak of “real people,” and wonder what the real people did. The real people. Who were they? They were the people other than myself. The good people. The capable people. The people who could do the things, I could not do: learn, study, retain ... all that garbage – which is what I have been talking of in class, and that’s exactly what I have been talking of – If you are told ... Listen to this. If the young child is told, he cannot understand. Then he takes it as a description of himself. What am I? I am that which cannot understand. And I saw you out there, when we were speaking of the concepts of...

CAROL: I can’t understand any of them.

JOHN: Well, then, that’s my fault. That’s not your fault. And that is not verbiage. That’s what I firmly hold to be the truth. And I am sorry, and I owe you an apology.

Nelson Mandela once said, 'If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart.' He was so right. When you make the effort to speak someone else's language, even if it's just basic phrases here and there, you are saying to them, 'I understand that you have a culture and identity that exists beyond me. I see you as a human being

"For if men needed speech in order to learn to think, they had a still greater need for knowing how to think in order to discover the art of speaking" - Rousseau

The trouble was that he was talking in philosophy but they were listening in gibberish.

A man thinks that by mouthing hard words he understands hard things.

Part of man's frustration is that he has become accustomed to expect language and thought to offer explanations which they cannot give. To want life to be intelligible in this sense is to want it to be something other than life.

They were presented in enigmas, clad in riddles, and taught by an wise men in the most mysterious way that could be devised, not because they contain some secret evil, or are contrary to the fundamental principles of the Law (as fools think who are only philosophers in their own eyes), but because of the incapacity of man to comprehend them at the beginning of his studies:

And once he had got really drunk on wine,
Then he would speak no language but Latin.

It has always been a mystery to me how Adam, Eve, and the serpent were taught the same language. Where did they get it? We know now, that it requires a great number of years to form a language; that it is of exceedingly slow growth. We also know that by language, man conveys to his fellows the impressions made upon him by what he sees, hears, smells and touches. We know that the language of the savage consists of a few sounds, capable of expressing only a few ideas or states of the mind, such as love, desire, fear, hatred, aversion and contempt. Many centuries are required to produce a language capable of expressing complex ideas. It does not seem to me that ideas can be manufactured by a deity and put in the brain of man. These ideas must be the result of observation and experience.

Sitting at a crowded table with men who did not share a common language with you, listening to them talk and jape whilst understanding none of it, had quickly grown wearisome. Particularly since he always found himself wondering if the japes and laughter were directed at him.
