Human central nervous system main purpose is to survive in time with least energy. To put it more simply it has to find repetition patterns in past to predict future. Typical human has inherited these patterns biologically from her/his direct parent and culturally by means of symbolic forms from others.Eextra-mission non-linear perspective and iconic/typical representation depict deep space-time but Intro-mission linear perspective and realistic representation depict moment to moment space-time. Also these two phenomenon are correlated respectively by pre-renaissance deductive logical system and post-renaissance inductive logical system and in an analogy they are cortex-like and spinal-like. As a result two type of perspective and representation methods depict and practice two different approaches for sur-viving in time and tradere them to next generation.
