Philosopher Alva Noe:
Imagine that we find the Holy Grail of neurobiology, the patterns of neural activation that correlate perfectly with different events in our mental lives. We would still never understand or make sense of why those correlations exist. There is no intrinsic relationship between the experience and the neural substrates of the experience. We always need to look at what factors bring the two together. The environment, other people, our needs and desires -- all these things exist outside the brain and have to be seen as essential parts of our selves and consciousness. So we aren't just our brains, we're not locked inside our craniums; we extend beyond our skulls, beyond our skin, into the world we occupy.
