On the notion of existence

I argue that a slight shift in our understanding of the notion of existence is needed in order to cope with the problem of external world and the problem of mind and body. As a consequence of it being taught by "givenness" of the subjective mind, and despite its applicability in objective contexts, it should be considered a "tool" akin to qualia, rather than pertaining to a "true", objective reality. In plain language, one's supposed relation with their surroundings is known to them only in terms of their private ontology. This conclusion is supported both by intuition and - perhaps most importantly - by ontological issues in quantum physics.
