Will he not fancy that the shadows which he formerly saw are truer than the objects which are now shown to him?
Humans are generally more comfortable when they feel as if they are the ones in control, so when the world which they thought they knew is turned upside down by new found knowledge, people will wish to “unsee” what they have discovered and go back to their old ways in which they feel in control and try to deny the truth of these new discoveries in any and every way possible, but…
It´s not just about being in control. It is more a evolutionary thing. You see the world as your social group does, it´s a learned thing. Once you are “wired” like that is not easy to “see” in a different way. If you do it would be more like a “conversion” than a evolution in thought. You are not going to see the world as a vietnamese if you are born in Nebraska. Experiences of the world that surrounds you and your social group will define it.
Knowing how this takes places, how we “function”, how we perceive in an anthropological and neurological point of view, is maybe the only way to disconnect this autopilot. Not even scientists are free of falling on their own caves (see “The structure of scientific revolutions” by Thomas S. Kuhn).
