Any reasoning is based on some assumptions and it is not a problem
All reasoning is based on assumptions and it’s a problem, because it makes it hard to converge on beliefs, or ever settle questions.
There’s a partial solution, in that not all assumptions are equal , and not all numbers of assumptions are equal.
That’s a fairly traditional version of Occams Razor based on minimising the number, and maximising the likelihood of assumptions.
Kant suggested on the margins one more proof of modal realism (I cite here by memory): “If a thing is possible in all aspects, there is no difference between it and real thing”.

Umm..well, suggestion, not proof.
