- For the movie matrix -> the idea originally comes from Plato.
- In his allegory of the cave ±> he describes what he sees as our sense of reality in this
- He said all humans are just like prisoners tied to some wall in a cave ± where they live
their entire life ± they are bonded/chained to it [they NEVER get out] ± they sit there &

- From outside: there is light coming from the fire that is casting shadows on the back of
the cave ± which is what the prisoners [humans] see. [shadows of whatever objects are
being carried in front of the fire]
- So the point is that reality as we perceive it according to Plato is extremely limited. We

- Prof disagrees with Plato.
- Though the idea that our sense of reality is really limited based on what we are able
to perceive is fair enough ± probably accurate. So only what we know of - somehow
we can incorporate into our understanding of reality. Also, we can use all sorts of
machines to expand our reality [e.g. using a microscope to see something that is
really tiny or use some special device to see UV light]
- But there is still the point that there is some limitation in our sense of reality ± that
is determined by what senses we have
- of course all that perception based on our senses are the products of evolution that has to
do with survival mechanisms associated with evolution [which points to the fact that
our perception is pretty much determined by what is really important for us to
perceive ±> which is the current view of things in response to Plato]
- So we perceive things that really matter to us! [ example of slide 15]

-so there is sensory input & a response to that [similar in animals/humans]
So in this plant example ± it illustrates that for this plant ± the only way to perceive
this world (importantly at least) is to sense touch ± as it helps the plant to catch flies.
So, the sense of reality for that plant is certainly VERY different from ours ± we
have WAY MORE senses & we use them in a more sophisticated way. But for a
simple plant ± that sense of touch is good enough.
