Aristotle distiguished between the All and the Infinite. The former is understood just what its comventionalconventional meaning states - it is everything. Whilst infinite means not finite. So no matter how much you have of somethimgsomething that is infinite, it is always possible to add more.
Another meaning of infinite is in Christian/Islamic theological discussion where human beings, as well as any created thing is called finite in opposition to God who is infinite.
In the early 20th Centiry two mathematical formalisations of mathematical infinity were found. These are the cardinals and the ordinal. Both generalise ordinary counting of finite sets to infinite sets.
So no, itsit is not empty of meaning.
