While we want a good perception of reality, we still can't perceive all reality at once. Furthermore, a oversensitive state of perception could be very annoying (overwhelming as seizures/epilepsy) as there are more sensations than can be processed properly.
We desire a safe and healthy self-control over our perceptionsystem of reality until omniscient powers arrive to our lives.
