Things aren't what they seem. Our perceptions have little to do with reality and are instead the outcome of filtering the input through multiple pre-installed prisms that can (and do) do a number on the incoming light. What is worse, the incoming light -- or what we perceive as light, as truth, as reality -- is, in the case of any incomplete, lacking personal participation, indirect, manipulated, or outright fake picture presented to us is pre-filtered for us through someone else's carefully installed prisms. Ulteriorly distorted, mind you.
The range of distortion may vary, from slight to total. Yet perceiving a totally distorted picture can be every bit as convincing to the observer as looking at an absolutely accurate one. More so, because distortions tax the brain, it's scientific fact (established in experiments with very young children, too young to have learned to lie) that lies require of our brain the kind of equilibristics and contortions that the rest of what we are can't possibly accept, and that's the beginning of the split, of the fragmentation of consciousness. The outcome may vary -- from mild stupidity to profound mental disorders.
