Wisey says: Haleivi- as I quoted before infinity cannot be divided into parts, even an infinite amount. (Shaar Hayichud) also space is finite that is why we are told not to delve into “mah l’maaleh, mah l’matah”
Which is why I wrote, “Our perception of space.” I’m talking about the concept of how any person relates to it.
Now, The Chovos Halevavos is not a Halacha Sefer, he is explaining and reasoning with you. He explains the logic of that statement that if you subtract a part then you’d have the infinite n-1 which obviouslt can’t be infinite. Then, if you put it back you’d have the new number+1 which can’t equal infinity, because they are two finite numbers.
That statement has nothing at all to do with relating to an area of an infinite object with finite rules. The problem he raises is about separating a part, or considering that it is made up of actual parts. As long as the finite divisions are not divisions of the whole object but are relating to the area that is in focus, these problems aren’t at play
