Bundle theory

Bundle theory is based on the believe, that objects are nothing more than their properties and relations. Taking away the properties or relations means taking away the object itself. In particular, there is no substance, that these properties inhere in.

Followers of this theory argue, that whenever we describe an object or imagine an object, we image or describe a property or relation. There is nothing we can imagine about any object that is not property or relation. In particular is it impossible to imagine some substance without any properties or relations.

However, since objects are nothing more than bundles of properties and relations, the question comes to mind, what ties those properties together. Since there is no substance they inhere in, some thing has to keep them together, bound to one object. They may just be conceived as a collection, a set, a bundle, but what puts them in this collection, is a question that has to be answered by followers of this theory.
