@Logicus,
OK lets analyse it then...
1 - The concept of nothingness exists.
2 - The concept of nothing reports the absence of something.
3 - The concept of nothingness implies something did exist.
4 - The concept of nothingness cannot report an absolute timeless permanent absence without loosing its meaning.
5 - Finally, the concept of nothing seams to "cannibalize" itself...nothingness is nothing...therefore there is no nothingness.
Nothingness has a common sense daily practical use like stating there is nothing in the freezer although we know there is air in the freezer n the freezer itself is there...when we stretch a word that was meant to be used in relative terms the word meaning breaks down...a good way of getting good concepts apart from bad concepts goes by pushing the limit of the implicit logic in the concept n see if it holds or breaks.
