We must find out to whom does this involuntary control system responds and who is controlling the so-called autonomic nervous system. It is fascinating to know that when we go against nature, the auto- nomic nervous system does not like it. For example, when we lie, we develop tremors of the hand, perspiration and palpitations. All these are signs which are used by lie detectors since the autonomic nervous system is not under our control. When I looked at the dissection of the eye and knew that the present camera is built on the way the eye is built, the fascinating thing to learn was that our images are created inverted as we see them, but in reality, we do not see the inverted image but the correct image as we see it.
Nobody knows to date.
When I looked at the skin, the protective covering of our bodies, it was more fascinating since skin was the only sensitive area of our body responding to pain. Therefore, when the skin is made numb by anesthetic agents, then it is easier for surgeons to cut the visceral organs. Now many years later, I read the words in Quran to the effect that when the wrongdoers are burned in the hellfire because of their crimes, they will be given a new skin so that they feel the pain continuously. How fascinating it is, that without a new skin, they could never receive the continuous pain after having been burned one time. What distinguishes man from other animals, and especially mammals, is the special features of the thumb.
