Conciousness

Jeff Hawkins
Theory of mind
7 levels of interaction
Perception input – filtered by expected input
Differences – filtered by expected differences
Ditto up to level 7 where we become “aware”
Humans are “predictive” machines
Your brain is predicting...

Daniel Dennet's take
We aren't as conscious as we might think
Unaware of changes – illusions vs perception
Built-in bias, “being conscious, I know what it is … and it can't be that simple”
The brain seems to be quite happy will the illusion of completeness
The “prediction” is assumed

Six Impossible Things
We seek explanations – Stories
We will fill in the missing parts
Explaining “Memes” are sticky
Which is why we hold “Beliefs”

Nova Science Now
Emergence
Ever increasing complexity
yields structure – order
Design “emerges” – Big Bang to Galaxies
Organic chemicals to cells
(Comets have both amino acids & water)
Complex cell structures to consciousness

“Pills to make you smart”
Cognitive Enhancement ----> H+
“Speculative Ethics”
What if there is a pill that
Makes you smarter?
Helps your memory?
Etc … like steroids do for athletes
