Till We Have Faces

Of course we all start with the idea that our senses put us in direct contact with reality—you think that your eyes are windows by which your brain “sees” the world. But science teaches you that your eye, or rather the nerve of your eye, is merely a telegraph wire. It’s [sic] vibration produces a feeling in your brain which we call colour etc.: but what the Something at the other end which starts the vibration may be, of this no human being can have any conception. No increase of our sensory keenness, no microscope or telescope can put us in any direct relation with the Thing: we still remain dependent on this long chain of communications, travelling by vibration from atom to atom: and we can never have any proof that the sensation which it produces in our brain conveys any true idea of the external Thing. ~ C.S. Lewis
