The ontological analysis of concrete particulars deals with the relationship between concrete object and their attributes. Both Peter Simons' Nuclear Theory and Aristotelian Substance Theory may present an acceptable explanation for the following three problems: Identity of Indiscernible, Excessive Necessitism and Change. In spite of the superiority of these two theories over the other theories, each has problems need to be addressed. Aristotelian theory does not seem to be very successful in showing that the spices (kinds) are unchangeable or at (...) least does not explain it. Simmons's theory also returns to Aristotelian theory. While outlining the challenges to any theory, the final suggestion of the paper is that with inspiration of Simmons' theory and introducing a relation between the generalities (universal Whatness), create a modification in Aristotelian theory to overcome the challenge of the irreductive challenge of Species (kinds) Simons' theory, in some sense, collapses back to Aristotelian Theory.

It can be argued (cf. Dizadji‑Bahmani et al. 2010) that an increase in coherence is one goal that drives reductionist enterprises. Consequently, the question if or how well this goal is achieved can serve as an epistemic criterion for evaluating both a concrete case of a purported reduction and our model of reduction : what conditions on the model allow for an increase in coherence ? In order to answer this question, I provide an analysis of the relation (...) between the reduction and the coherence of two theories. The underlying model of reduction is a (generalised) Nagelian model (cf. Nagel 1970, Schaffner 1974, Dizadji‑Bahmani et al. 2010). For coherence, different measures have been put forward (e.g. Shogenji 1999, Olsson 2002, Fitelson 2003, Bovens & Hartmann 2003). However, since there are counterexamples to each proposed coherence measure, we should be careful that the analysis be sufficiently stable (in a sense to be specified). It will turn out that this can be done. (shrink)
