What is the difference between a thing that is real and a thing that is an illusion?
What makes a thing real?
What makes a thing an illusion?
What in this universe is real and what in this universe is an illusion?
Isn't being an illusion a way of being real?????
I don't understanding the distinction
One ambiguous line in the sand are magic tricks. Magic can appear to be real to the eyes. However, once it appears to defy common sense and/or even the laws of nature, we know there is a trick involved. If the trick is done well, we may have problems figuring out how it works. Until you figure out how it works, the illusion remains real to someone.
Applied Science can create new things that do not appear naturally under natural laws. Cell phones do not grow on trees or hatch from eggs. They begin as an illusion in the imagination, until the illusion becomes real and ready for market. This is sort of like magic; something from nothing with no natural explanation. There is an artificial or manufactured explanation.
There are other types of illusions and magic tricks. For example, in the US, the Biden family influence business has been up and running for years, but we are told President Biden was clueless of this and had no knowledge or connection. This trick is like the magician sawing his lovely assistant in half, with both halves of her still able to function, without the other. Many people believe this is possible, while others look for the hidden wires or mirrors.
Say someone commits a crime, but he gets off on a technically. Since there was no justice served, does that make him innocent? This is also a type of magic trick where the line between real and illusion is not clear cut. This magic is done with law and lawyers acting as magicians.
Politics also deal in illusions and magic tricks where the line between real and illusion is blurred. Fake news takes this to the next level selling fiction as fact until the line is also blurred.
Statistics is another illusion maker. One sets the stage by hiding the evidence in a black box; nothing up my sleeve. The magician can then pull a rabbit out of that hat. Many are not sure where reality and illusion start and stop. We are all at risk even if nothing happens. Math that relies on a black box is a gift to the magician's guild. It is OK in a factory or casino, since they both conjure products that started in thin air.
