It must be real, but it is not always apparent what its true nature is, i.e. it may be an illusion.Originally posted by Hurkyl
Can something I have sensed not be real?
Depends on the nature of the illusion.How do I distinguish between reality and illusion?
Yes. They are causal, i.e. they consist of matter in motion. NOTE: This is based in Sorce Theory in which EVERYTHING is made of matter in motion. In the Standard Model they could be made of energy (whateverthatmeans) or they could even be vacuum fluctuations, i.e. virtual particles, etc. [made of mathematics not causality]Do real things have properties? If so, how do I know what they are?
