Talking in extremes, imagine the situation. One man expects great evil of another, how much love could be perceived from where hate is expected?
All we see is our own perception. 2 layers, our brain makes our perception, or what we imagine becomes true. That is too say... all we see is our own perception because we literally can't see past our perception, because our perception is 'created in the brain' (our vision system for instance, start by looking for straight lines etc and builds our 'view' from there) but a large part of seeing is driven by our pervious learning, we see a chair or a dog because we expect too, we see a religion as being universally evil because when we 'look', we find all the evidence to support our opinion.
So perception is one part guesswork, one part learning what to expect too see in the future, and basing more guesswork on those learnings... our perception informs our estimations of the world, and estimations inform our future perceptions, all of which comes from inside us.
All we see is our perception.
