Towards a Working Trope Ontology

In the present paper, I argue that a one-category ontology, based upon individual property-instances (tropes) only, is to be preferred. I show that the traditional alternatives have insurmountable problems, and formulate trope ontology in such a way that it can solve them, and also overcome the difficulties on the basis of which criticisms are usually moved against tropes themselves. Lastly, I show that a specific understanding of tropes can be extracted from contemporary physics.
