Clouds, 127 illus

On the other hand there are also assumptions built into our perception, which are, for example, the basis of our visual illusions. Thus we perceive the moon moving against the clouds, since we hypothesize that objects move in a static environment, which fits to our immediate earthly environment. Here it is important to spot a moving object, be it a predator or prey, in minimum time. That we fall prey to an illusion, when we look up at the sky, does not really matter. In addition we know that we categorize and thus impose an order onto and into what we perceive. Colour perception is a good example.
