Atheism is untenable in the 21st Century
"Can a phenomenon-in-potentia be said to exist and not to exist?"
What a fabulous question. I'm going to think about that for a while. The short answer could be that Being is both a noun and a verb
In the meantime consider the following. Time is required for Humans to exist thus a metaphorical bullet point:
1. During procreation a seed is planted.
2. Time is required for its development
3. Existence requires time
4. Time is existence.
What do you call a human being at conception other than a fetus?
Is it a person, half person, human being in the making... ?
Just a strange analogy using words and concepts...
