I don't understand the bold and underline texts.Have you searched for this? I get a wiki-article, some articles (scholarly and otherwise) and a few videos that claim to provide explanations.
(For example, to my relief, I just learned from this that I apparently side with the majority of mathematicians that "accept actual infinities".)
If you have a more specific question, I am quite sure there are more capable people here to answer it.
Note: I think one of the confusions that often appears in such discussions, is that people oppose the actually infinite on the grounds of limitations imposed by physical reality. This is not correct: Rather, the discussion does not depend on physical, but philosophical and foundational constraints.
Physical quantities such as mass and velocity have a finite magnitude. (In the case of velocity, there is even a particular upper bound.) However, this is not relevant in the context of "actual vs. potential infinity", because in that context we are concerned with sets as abstract mathematical structures, not as representations of the values of physical quantities.I don't understand the bold and underline texts.
Can you explain it?
