عنوان مقاله [English]
The subjective considerations of "negatively-conditioned", "non-conditioned" and "conditioned-by-something" are of special importance in Avicenna's philosophy. For him, they are used both, in quiddity and in existence. What has been the focus of study and research in this article is that according to Avicenna, these subjective considerations are used in general concepts and as a result, the relationship between the subject and the object and the various aspects of indicating of a general concept are explained. The main usage of these subjective considerations is in concepts and quiddities, in order to explain the natural universal (and that how it exists in the concrete) and to reject Platonic Ideas and to distinguish between genus and matter. However, on the other hand, by running these subjective considerations in the concept of existence, portions of the concept of existence are obtained that, in addition to creating analogical gradation in existence, it makes the Necessary Being have a real determination in the mind and as a result we can deny or prove the attributes of God, so that it has epistemological validity. Avicenna defines the existence of God as "negatively-conditioned" in a way that it cannot be considered contrary to "non-conditioned" which is mentioned for God in the words of mystics.
