Abstract

Performance depending on whether the nature of Aristotle and being able to master the principles of the word transposition of these two predicates are divided into four categories: accidents , species , properties and definitions This division is preset -based word. In fact, is also available for individual things, predicate, in this case, four kinds of predicates should be replaced by one of the species. Division of the operation from the predicate term object point of view, duality and non-compound word species, and features the words and definitions are complex, the latter by the former compound to illustrate. Therefore, the predicate in the most abstract level should not be divided into four categories, but should be divided into two categories, namely, species, and duality. Characteristics and definition of Aristotle unconsciously introduced the principle of subsidiarity on the two types of composite predicate to the result: the introduction of the principle of the duality mode inevitable accident and chance into duality, features and all kinds of definitions and inevitable duality complexes; the introduction of the principle of unity to distinguish between species characteristics and definitions - those who divide things in the process of layer by layer to maintain the unity of the species is the inevitable duality difference , while the poor and the kinds of complex material is defined. However, for any duality species has its own unity, and thus Aristotle said, the difference can not be deduced from the various principles. Based the capacities to express the nature and change position with the subjects, Aristotle divides predicates into for categories: accident, genus, property and definition. In this division, "species" is assumed to be a subject. Yet, in fact, "species" can also be a predicate. In this regard, genus, one of the four predicates, should be changed to genus-species. Considering the division of predicates, accident and genus-species are non-compound phrases; property and definition are compound phrases, while the latter can be explained by the compoundness of the former. Therefore, on the most abstract level, predicates should be divided into two rather than four categories, and the two categories are genus-species and accident. Property and definition are the results of the fact that Aristotle unconsciously introduces two subsidiary principles to compound the two categories of predicates. He introduces the modal principle to divide accident into necessary accident and accidental accident, while both property and definition are compounds of genus and necessary accident ; the unitary principle of genus-species was introduces to separate property from definition-the necessary accident that could maintain the unitary principle of genus-species in the process of dividing things level by level is "differentia," while the compound of differentia and genus is definition. But, since any accident has its own genus-species unity, Aristotle's idea of ​​differentia can not be inferred from his principles
