As we develop better technologies for probing the brain, we detect more problems.

In the traditionally taught view of perception, data from the sensorium pours into the brain, works its way up the sensory hierarchy, and makes itself seen, heard, smelled, tasted, felt - "perceived." But a closer examination of the data suggests this is incorrect. The brain is properly thought of as a mostly closed system that runs on its own internally generated activity.

You are part of a complex social network that changes your biology with every interaction, and which your actions can change.

Who you are depends on the sum total of your neurobiology.

...you are battered and bruised in the collisions between reminiscence and reality.

Asleep vision (dreaming) is perception that is not tied down to anything in the real world; waking perception is something like dreaming with a little more commitment to what's in front of you.

We are made up of an entire parliament of pieces and parts and subsystems. Beyond a collection of local expert systems, we are collections of overlapping, ceaselessly reinvented mechanism, a group of competing factions. The conscious mind fabricates stories to explain the sometimes inexplicable dynamics of the subsystem inside brain. It can be disquieting to consider the extent to which all of our actions are driven by hardwired systems doing what they do best while we overlay stories about choices.
