摘要：The goal of this article is to study Aristotle’s concept of philosophical principles. Metaphysics required from a philosopher to reveal the axioms of his teaching. It declared the law of contradiction as the most certain of all principles and axioms. This article proves that Aristotelian definition of truth makes it necessary to accept the ontological formulations of all the three main laws of thought as axioms of first philosophy. This article points out the absence of any reference in Metaphysics on Categorias and vice versa. This circumstance questions if could Aristotle be the author of the both works? Authors of this article underline that the modern trend of meta-philosophical studies requires investigating the possibility of building the system of axiomatic philosophy.
