Abstract
Aristotle gives a definition of "universal" that Łukasiewicz considers non-comprehensive because it does not include null universals. In addition, Aristotle's definition of a particular can be understood in two ways: (1) a particular can only be predicated on one thing, (2) a particular cannot be predicated. This double conception, which is repeated with great frequency in the words of Aristotle's commentators, on the one hand, calls into question the opinion of Koons and Pickavance - who believe that a particular in Aristotle's view is unpredicable; And on the other hand, it is a conflict that must be resolved. In this essay, it will be shown that, firstly, Łukasiewicz's objection is not relevent and Aristotle's definition also includes null universals; And secondly, the conflict that seems to arise from the definition of particular can be resolved by distinguishing two types of predication, "in the manner of one name" and "not in the manner of one name".
