It is controversial if existence is a general class that can be categorized into existence in the mind and existence in reality or if there are multiple levels of existence. It is also controversial that there are only two categories of existence, if at all it can be categorized. Hence, for a supreme being, for which, as suggested by Thomas Aquinas, it is not very clear whether humans can perceive all of its qualities, a conclusion that God does not solely exists in the mind, should not lead to a conclusion that it exists in
