As far as I know, Aristotelianism and Thomism state that a material being is always potentially sensible. For example, there are microorganisms that we cannot see with the naked eye. But if we use a microscope, we can sense them. There seems to exist an identity between ens materiale and ens sensible. However, why is a material being always potentially sensible?
Aristotelianism or Thomism probably deny the existence of a material being that is not sensible, even potentially, as incoherent. What is the reason of such incoherency? What is there in material beings that make them always sensible, at least potentially?
