The case for (tel)empathy:
I'd like to begin with a joke, comparing the concept of telepathy as we all know it, (hearing other people's thoughts) to something as real as quantum physics, for example. I often read proofs of the form, since this would model exactly, for all intents and purposes it can be considered that which it is modelling.
If someone could imagine what you're thinking, then there would be little difference between that and actual telepathy. So, try and imagine what people are thinking. Find out if you were right, when possible. The better you get, the closer you'll get to telepathy.
Well maybe not, but it's probably a thoughtful way to live. Real telepathy, wouldn't it improve the quality of life? Less accidents, less misunderstandings.. Everyone's heard of brainwaves, right? I've heard two brains close together oscillate at the same rate. How much information can those waves carry? It doesn't have to be a lot, when things get down to the cellular level (i.e. neurons). Chaos theory is fond of quoting it's butterfly-causing-storms scenario, and while my brain is probably more organized than governed by chance, little static fields around my hair could send little electrical signals (how cells communicate) which can easily be amplified 1000 times over by metabotropic G-proteins.
So maybe all the information stored in the brain can be transmitted this way, visuals, memories, etc.
