Abstract

Some philosophers have claimed that one must be acquainted with the elements of one's ontology. Also, believing that substrata and universals are required in an adequate ontology, these philosophers have claimed acquaintance with such objects. This paper attempts to analyze what is involved in such claims and to argue that they result from a number of confusions. The paper deals largely with the claim that substrata, or bare particulars, are presented since numerical difference is a simple fact that is presented. It further attempts to argue that while neither substrata nor universals, as such, are objects of acquaintance, there are some distinctions to be drawn between talk of universals as presented objects and talk of substrata being presented
