ARISTOTLE’S MEANINGS OF "ONE"
The purpose of the article is to consider the meanings of the «one» in Aristotle’s philosophy in connection with its influence on scholastic metaphysics and in the context of contemporary research in philosophical literature. The methodological task is to analyze the texts of Aristotle and to interpret the obtained results in the light of the concepts of authoritative scientists in the history of philosophy. Two main meanings of the «one» in Aristotle’s philosophy are revealed as a result of the inquiry - the ontological one and the cosmological one. It is argued that ontological «one», as unity in essence, is the main sense of the «one» because the thing is one and has existence due to its essence; whereas cosmological «one» is a causal unity. The theoretical significance of the inquiry is that the analysis of the meanings of «one» in Aristotle’s philosophy offers new possibilities for understanding the continuity of ideas and concepts of philosophy from ancient metaphysics to medieval and subsequent forms of philosophical thought.
