You've Never Seen Anything Happen

Some event happens before you in a lighted environment.

Light bounces off of the entities involved in the event and some of it meets with your eyes. It travels through your cornea, then the aqueous humor, the lens, and the vitreous humor. When it strikes your retina, cells convert the light into electrical energy and route these impulses to the optic nerve. After traveling the distance of the optic nerve, the electrical signals are processed by a special region of the brain into the sensation of seeing. Finally, other parts of the brain generate a storm of electro-chemical activity to recognize and classify the elements of vision that has been generated. Since all of this happens without your awareness, the conscious part of your mind is free to busy itself with rationalizing the classifications and their significance to you.

All of this happens at a rate of speed that is consistent among human beings. This rate of speed roughly corresponds to the 24 - 30 frames per second that film and video technology uses to fool the mind into thinking it is seeing things move on a movie screen or television. (instead of noticing the actual still images which make up each video frame) If activity happens at a speed faster than 30 times per second, all you notice is a blur - such as the beating of a hummingbird's wings or the spinning of the spokes on car wheel rims.

Think of all the processes visual information goes through in order to produce the experience of sight.

• Manipulation: The eye lens focuses the light, flipping it upside down in the process


• Conversion: the light photons are chemically converted to electricity


• Transmission: the electric impulses are routed to the optic nerve which carries them to the brain


• Synthesis: the occipital lobe of the brain processes the impulses at a coherent rate, producing the sensation of vision


• Filtering: the temporal lobe of the brain pre-screens the data to point out elements linked with our emotions (such as a spider if we are afraid of spiders)


• Analysis: the frontal lobe of the brain associates visual elements with memories and produces reasonings about their significance

What a wonderous mechanism! And all you ever do (in your conscious state) is concentrate on the reasonings and interpretations provided by the frontal lobe. The rest of it "just works" (most of the time). Now, all of this processing takes time and there is undoubtedly information lost at all of the junctures of the system. There is no doubt that you see something.

But you've never seen anything happen.
