The interplay between relations, substances, and existence

Abstract

This thesis explores the ontology of relations and the implications of it. I make the case that relations between multiple substances are impossible. Furthermore, I argue that existence is a predicate, and can therefore be the predicate of a relation. I do this to push the argument that substances cannot exist in relation to each other. The conclusion I make from this is that only one substance can exist, since otherwise a substance could exist in relation to another substance. This conclusion, I point out, is the doctrine of substance monism. Furthermore, I argue that the self exists, because it is given in experience. Because the self is a substance, and I have argued for substance monism, the self is the only substance there is. This conclusion is idealism, and, in conjunction with substance monism, necessitates solipsism.
