A Criterion for Differentiating between Theorematical Disciplines

The issue of differentiation between various branches of knowledge and its criteria are discussed in a variety of academic disciplines. This article suggests that the differentiation between different theorematical disciplines is determined on the basis of their subject matters, and these disciplines study solely the essential accidents of their subject matters. To establish this issue, the author defines a theorem as a syllogism that culminates in certainty. Then he explains about the reality of certainty, and makes some clarifications about essential accidents. And he claims a real unity among theorematical disciplines. The article ends with a discussion on the descriptive or normative nature of sciences.
