What they [recent discoveries about neurons] appear to tell us is that humans are first and foremost mimics. We make ourselves up as we go along by improvising from what we see. This model also suggests the self is in dynamic interaction with otherness, both copying behaviour and projecting its emotions on to others, which is the basis for the vital human quality of empathy. (Ramachandran speculated in 2000 that autism was caused by deficient mirror neurons and medical research is now going in this direction.)
It's Ramachandran's contention that self-reflection was formed somewhere in this process of self-projection. The mirror-neuron system enables us to see another person's point of view, what's known as an allocentric view, as opposed to an egocentric one. Ramachandran suggests that "at some point in evolution, this system turned back and allowed you to create an allocentric view of yourself. This is, I claim, the dawn of self-awareness".
