Synesthesia is a real condition of crossing senses. Someone may see a color that hurts their ears, while another may see numbers in different colors. It is an interesting phenomenon where senses cross neurons in visual/cerebral perception, and may attribute smells to pain, or shapes such as a triangle may physically perceptually be seen in yellow. Below is one example. A “normal” acuity would see all black, but a synesthesia patient may see green or red. .
And if a subject sees W’s as a color, this test takes less than a second.
Synesthesia is not only seen and present in religion, it is promoted. Seeing a cross can cause tears of pain or joy, hearing a lie can cause belief, and talking out loud followed by an amen, can fondle hope in religious subjects. But this type of behavior is learned, and once believed, it is tolerated.
While most synesthesics feel what they are seeing as normal , 98% of the population sees it as an enigma. To someone that believes in the supernatural god, it may seem natural or necessary, but it is not. But to the theist or the synesthesiac, it requires an outside observer to recognize the flaw.
Thousands of gods have dissipated into near oblivion. Where are they now? They are parked in the annuls and history books, but those from the time thought them to be immortal. While red may be a color, it also may have a smell. Whatever your eyesight tells your mind, deconversion has a sweet ring to it.
