In Ontology, quality determines beings. The quality-quantity bipolarity reveals that a conceptual logical comprehension that can include negation must be a dialectical logic. Quality is a precise characteristic of something (or a subject predicate) capable of augmentation or diminution while remaining identical through differences or quantitative changes. Thus, quality and in opposition quantity are inextricably linked, giving definition to each other, so constituting a logical bipolarity. The theory is that a magnitude G is never separated from secondary qualities α and β, and therefore, a measure depends on a concrete quality Gα or Gβ, that is to say on one pole of a logical bi-pole. However, the particular number, the unit, that expresses the result of a measure is the quality G alone. Examples drawn from physical and chemical experiments illustrate these ideas and elaborate the structure of the concept of opposition between the secondary qualities α and β of a magnitude G.

在本体论中，质量决定着众生。质量-数量双极性表明，可以包括否定的概念逻辑理解必须是辩证逻辑。质量是事物（或主题谓词）能够增加或减少而同时通过差异或数量变化而保持相同的精确特征。因此，质量和相对数量是密不可分的，相互定义，从而构成逻辑双极性。从理论上讲，幅度G永远不会与次要质量α和β分开，因此，度量取决于具体的质量Gα或Gβ，也就是说，取决于逻辑双极的一个极。但是，表示度量结果的特定数字（单位）仅是质量G。
