Abstract

The ontology of the "tractatus", In terms of which objects are characterized as propertyless simples, Is coherent provided wittgenstein is not mistakenly taken to be a constructive atomist building complexes from simples. A geometrical model is given to illustrate this. It is also shown that an ontology like that of the "tractus" removes much of the conceptual puzzlement of modern particle physics and has implications for current debates about realism, Possible worlds and rigid designators
