unity of attributes and its relation to the unity of referent and multiplicity of concept

the subject of the present article is the problem concerning the unity of attributes and its relation to the unity of referent and multiplicity of concepts. in this problem, the theory of non-revealingness (‘adam-i kāshifiyat) of the multiplicity of concepts from multiplicity of referent is proved; and the rival theory, i.e., the revealingness of the multiplicity of concept from the multiplicity of referent is disproved. the main purpose of bringing up the above issue is to elucidate the unity of attributes theory. the research method of the article is conceptual and propositional analysis and the approach is logical-analytical. the most important outcomes that this article has achieved are: 1. the concept of wāḥid (one) denotes referent only in terms of its meaning and not in other terms; thus, applying of multiple concepts to a single (wāḥid) referent of one is permissible; 2. the referent of existence integrates and originates the abstraction of multiple concepts; 3. application of contradictory concepts to one essence would not necessitate contradiction in referent, except in modal difference or real contradiction.
