Well, I hate to admit it, but it is possible that there is (one) such a thing as telepathy and (two) that the CETI project's idea that we might communicate with extraterrestrial beings via telepathy is possibly a reasonable idea--if telepathy exists and if ETIs exist. Otherwise we are trying to communicate with someone who doesn't exist with a system which doesn't work.
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.
..giving power to negative thoughts or fears was bringing ideas to life in physical world,idea in mind became emotion in heart,emotion turned into words spoken,written,painted,strummed across guitar strings,or vibrantly held note by Tibetan singing bowl, thoughts affected physical world.
Shared emotions experienced by two souls,empathy on unequivocal level which Davey believed would change entire species of mankind if only secret of empathy could be telepathically shared with humanity,one soul after another, until every soul understood true meaning of love.
In science fiction, telepaths often communicate across language barriers, since thoughts are considered to be universal. However, this might not be true. Emotions and feelings may well be nonverbal and universal, so that one could telepathically send them to anyone, but rational thinking is so closely tied to language that it is very unlikely that complex thoughts could be sent across language barriers. Words will still be sent telepathically in their original language.
