“All use of speech implies convention and therefore at least duality of minds. The problem of communication through language may in this light be seen as the search for the means supplied by the conventions (or code) to transmit a message from one mind to another. (This definition is as applicable to "literary" communication as it is to "non-literary.") ...Is the code exactly the same for transmitter and receiver? Indeed, can it ever be? It hardly seems likely, since in the strict sense no two people have ever acquired exactly the same code. Consequently, the correspondence between the writer's understand of his writing (I do not, of course, mean merely a conscious or reflective understanding) and the reader's understanding of it will be at least approximate. Another variable is the mental, emotional, and cultural constitution of the being who used the code to transmit a message, and of the being who decodes it. To what extent are they capable of understanding each other? To what extent will they be willing to cooperate in dealing with the inevitable problems in communication? To what extent will anticipated or actual reaction ("feedback") from the receiver affect the framing of the message? Perhaps more important than any of these variables, there is the as yet unresolved question of the very nature of language, and therefore of communication through language. What do agreed upon symbols stand for? Is it conceivable that they correspond to something objectively identifiable? Perhaps not. But even so, is it conceivable that a given message can recreate in another mind whatever it is supposed in the first place to represent in the mind of the sender? All of these questions are in the last analysis as relevant to literary studies as they are linguistics”

“They must talk to each other directly, Ender, mind to mind. What one thinks, another can also think; what one remembers, another can also re-member. Why would they ever develop language? Why would they ever learn to read and write? How would they know what reading and writing were if they saw them? Or signals? Or numbers? Or anything that we use to communicate? This isn’t just a matter of translating from one language to another. They don’t have a language at all. We used every means we could think of to communicate with them, but they don’t even have the machinery to know we’re signaling. And maybe they’ve been trying to think to us, and they can’t understand why we don’t respond.”

“You can have the best message in the world, but the person on the receiving end will always understand it through the prism of his or her own emotions, preconceptions, prejudices, and preexisting beliefs. It's not enough to be correct or reasonable or even brilliant. The key to successful communication is to take the imaginative leap of stuffing yourself into your listener's shoes to know what they are thinking and feeling in the deepest recesses of their mind and heart. How that person perceives what you say is even more real, at least in a practical sense, than how you perceive yourself.”

“It is true that a writer writes first to please himself and that his own satisfaction with what he has done is perhaps his greatest satisfaction. But writing is a means of communication. It is not enough to speak; you must also be heard. The message must be received and understood.”

“Men understand direct communication. It's bitches who speak in code.”

“To say exactly what one means, even to one's own private satisfaction, is difficult. To say exactly what one means and to involve another person is harder still. Communication between you and me relies on assumptions, associations, commonalities and a kind of agreed shorthand, which no-one could precisely define but which everyone would admit exists. That is one reason why it is an effort to have a proper conversation in a foreign language. Even if I am quite fluent, even if I understand the dictionary definitions of words and phrases, I cannot rely on a shorthand with the other party, whose habit of mind is subtly different from my own. Nevertheless, all of us know of times when we have not been able to communicate in words a deep emotion and yet we know we have been understood. This can happen in the most foreign of foreign parts and it can happen in our own homes. It would seem that for most of us, most of the time, communication depends on more than words.”
