Introducing conceptual limit and acknowledgement modal by Abolbarakt and analyzing Aviccena thoughts

Abolbarakt was a great thinker who has critical sight on Avicenna. In this article, we try to mark him as a mind theoretician and we will give two evidences which can be considered as his innovations. One is conceptual limit (Hadde-Mafhumi) as an alternative for true limit, and the second is acknowledgment modal instead of modal of proposition. Then we analyze these thoughts and show how they are presented in subsequent logical texts.
The theory of conceptual limit as an alternative for true limit (Hadde-Haghighi) is a consequence of our method of naming objects. That is, objects is named according to our knowledge with respect to them, so instead of knowing objects, it may be adequate to know limits of our knowledge and what we recognize from objects. Besides, by accepting acknowledgement modal instead of modal of proposition, we encounter with a new concept in modal logic. However, this theory is not useful, since the introduction of deduction is evident. We note that both theories exist in the heart of Avicenna’s thoughts, but Abolbarakt use them in the other places
