The ability to change perspective is vital for our interaction with the environment. There is nothing more vulnerable than our visual system which contributes to about 80 to 90 % to our perception. We should become aware about the fact that the world we perceive is merely a construct of our brain's activity. What we perceive is not a true map of our environment. Here a few intriguing examples:
A more detailed article on this topic is included in the 'Science' section of this website:
"Our major interaction with the environment occurs via the visual system. Everybody's brain is capable to reconstruct surroundings in three spatial dimensions. We are 3D-animals which do not possess an intrinsic way of consciously measuring time or other dimensions. Perspective results from the brain's computation of electrical signaling initiated by a set of shapes, brightness levels and contrasts.
However, as a result of system-inherent restrictions even our 3D perception of the outer world is unprecise: Incoming signals are processed with a specific uncertainty and ambiguity. Therefore, optical illusions are part of our quotidian lives. What you see is what your brain perceives: a digitalized blurred interpolated version of the environment. The degree of details in the brains representation of the outer world largely depends on the focus of attention, context, and emotional evaluation." ... more
