Your brain never directly sees the light of day
Nor does it smell, feel or hear anything of its own accord.
Instead, it sits there, walled off
Inside the cavity of your skull
Drawing inferences from your nerves and sensory organs
Conjuring up a world of its own from all of this information
Filtering to fit with its biases
A computer, computing.
And yet, as far as we know
This is how you come to know the world and your experience in it.
