Realism should only be the means of expression of religious genius... or, at the other extreme, the artistic expressions of monkeys which are quite satisfied with mere imitation. In fact, art is never realistic though sometimes it is tempted to be. To be really realistic a description would have to be endless.
Reality is what we take to be true. What we take to be true is what we believe. What we believe is based upon our perceptions. What we perceive depends upon what we look for. What we look for depends upon what we think. What we think depends upon what we perceive. What we perceive determines what we believe. What we believe determines what we take to be true. what we take to be true is our reality.
