Right now, neurons in your head are firing and generating thoughts and concepts in response to light hitting your eyes in patterns that were created to represent thoughts in my head - there is a chain of direct physical phenomena that stretch from my brain to your brain that are affecting thoughts in your head right now. In person, it's even more direct - neuronal firing patterns in my brain cause jostling air molecules which incite neuronal firing patterns in your head. In a very real and direct way, my neuronal firing patterns influence your neuronal firing patterns.
What's amazing is that this extends out through time and distance - my neuronal firing patterns are shaped and affected by the neuronal firing patterns of beings long dead through both the same direct mechanisms described above and more indirect mechanisms mediated through other beings over time - in fact, by the time you've read this far, I'll have indelibly impacted your neuronal firing patterns. You'll never think again in a way that's not influenced by my thinking.
