قول به اصالت وجود در میان معاصران صدرا، لااقل در میان شاگردان میرداماد، با اقبال چندانی مواجه نشد، اما پس از ملاصدرا شاگردان وی اصالت وجود را پذیرفتند و حتی حکیم لاهیجی، که برخی او را اصالت ماهوی میدانند، به اصالت وجود قائل بوده است؛ رجبعلی تبریزی و شاگردانش، که به جریان فرعی اصفهان موسوم شدهاند، نیز گویا، تحت تأثیر ملاصدرا، البته با تقریری که با اصول حکمت متعالیه سازگار نیست، به عینیت وجود قائل شدند.

The Relationship of Mind and Phenomenal Objects in the Epistemologies of Mulla Sadra and Kant
In Western and Islamic philosophy, one of the most complex and controversial ontological topics has do with the relationship between mind and phenomenal objects, that is the relationship between the form in the mind and the material and objective form. This issue has stirred great confusion for philosophers seeking to explain the relationship of knowledge and the "outside world". In this article we present and compare Kant and Mulla Sadra's philosophical solutions to this problem.
Although in Mulla Sadra's philosophy, mind and phenomenal objects do not stand on the same ontological levels, however according to the "primacy of existence" (Aṣālat al-wujūd) principle, the two are alongside each other. Knowledge is not separate from ontology and relies on the outside world in its process of perception occurring through the help of the senses, the imagination, reason, and intuition. What occurs between the outside world and the mind is called by Mulla Sadra the construction of quiddity. Quiddity is neither bound to the mind or the outside world; however it is necessary on every ontological level and participates in all the levels of perception. Mulla Sadra can explain the relationship between the intuitions of the mind and the outside world first by positing a soul which creates forms and elements related to perception and secondly, by filling the gap between mind and phenomenal objects by postulating a division of ontological levels.
According to Kant, knowledge requires two things: a) observation, which is given to us in space and time and b) the reception of an intelligible upon what has been observed. For the process to occur the phenomenal object and the intelligible must share a similarity. Some intelligibles have no similarity with anything from the experiential level. Kant, in trying to reconcile mind and the phenomenal objects uses the concept of Transcendental Schemata, that is forms produced in time by the imagination. By arguing for a direct reciprocity between the phenomena and the intelligible, Kant is bound to uphold the reciprocity between phenomena and transience.
