Let me give some addition here to be little bit more precise.
Mathematical intuition can be started from anything,
but it becomes a true mathematical one only after formalization.
Of course, we can presentiment it in some our first vague ideas.
(But we could mistake in this presentiment.)
Essentially I see nothing in my understanding what would contradict
to this message of Charles Silver (which I omit here almost completely).
I also think that Kit Fine was not very precise by saying

According to the message of of Charles Silver, Kit Fine did not
neglect rigor, he just found some appropriate formalism for,
firstly, vague idea of "arbitrary object". (Unfortunately,
I myself did not read his book and cannot say anything more.)
