I am referring to a thought construct I use(along with many others) when contemplating the nature of existence, reality, self etc.
You see there is something curious about existence, when you examine it, it appears not to be what it at first appears to be. What it appears to be when examined turns out to be one thing* acting out the appearance of many things.
This begs various questions.
Science is great at learning about (and applying that learning) the tangible world of matter and energy.
However if one is interested in the questions begged above you must look elswhere.
*energy whatever that is.
