Catalyst and randomness

[BrownEye]

The viewfinder experiment blew me away. That was yet another realization for me as to how the mind can modify what we perceive. That was a pretty awesome moment for me.

I look at how multiple witnesses to the same event will have "seen" something different. What they see tends to be largely influenced by previous experience which will be different for each of them.

So our perception seems to ride on previous experience, and when you peel all of that away back to the time of your birth, what were you able to perceive in the beginning?
