Purpose/Significance of Optical Illusion?
There are people who believe explicitly in God, at least they claim they do. To them there is no sloppy overflow in God's natural universe. God does not do anything approximately, but everything precisely, they believe. Everything God does and has created is real. Creation is part of the definition of real after all, when you think about it.
If God has a purpose in everything, what is the purpose of optical illusion? Why was a choice made to give us senses that are often unreliable? Surely, God could have done it differently if that being has only a portion of the control over the universe attributed to him by his faithful. To say that God works in mysterious ways, is the ultimate cop-out and an explanation of nothing. It explains that you do not have an answer, or anything close to one.
For years I have suspected that Buddha got very close to the truth with his notion of Maya. It seems to me now that there is a lot more to optical illusion than the little bit one finds in entertaining books on the subject. Formal optical illusions presented in books cannot be controlled or prevented when we follow directions and look at the right spot, etc.
Does God really have some interest in fooling and testing people. That idea seems awfully old fashioned to me. In my early life there was an aunt who insisted that even dinosaur bones were something put there to tempt man from God's words.
I do not know if God has an interest in testing us, but from all the evidence, it seems said entity does have an interest in fooling us, otherwise why give us senses that cannot be relied upon consistently?
If there is a God, what then is the purpose of optical illusion? I suspect that a great deal of what we experience is an illusion of one variety or another, just not the kind slick and obvious enough to include in a coffee table book on illusions and paradoxes. But what is the purpose, then? What is a human supposed to take from a world whose content is so steeped in illusion? What is the lesson? Why illusion instead of direct truth, if you were God?
