Is nothing not a concept? A term? A word? Something?
That which is perceived indicates existence and the term or concept “nothing” is clearly perceived in the statement above and here as well.
It isn’t an empty claim. It establishes testable criteria allowing verification of existence through perception and interaction. Nothing fails because it cannot be perceived or interacted with. The concept is not actually nothing or nonexistence. The concept, being perceived or interacted with, is existence.
This is also discussed in the Nonexistence Cannot Be section of the essay.
The concept is Biblical:
“For with God nothing shall be impossible.” Luke 1:37
