The theory of Imkān-i Faqrī (Existential Poverty) is one of the notable and novel ideas of Mullā Ṣadrā, forming the foundation of many of his important views. According to this theory, all beings are entirely poor (‘ayn al-faqr) with respect to the Almighty. Consequently, the effect is understood as a refined manifestation of its cause, and the separation between cause and effect - as posited in the Peripatetic philosophy - is deemed invalid. Furthermore, Mullā Ṣadrā provides a demonstrative explanation for the gradation (tashkīk) of existence. Hence, faqr (poverty), which constitutes the very being of contingent and caused entities, must itself be subject to gradation. This article distinguishes between two types of poverty: (1) affirmative poverty, which may be described as dependence and attachment, and (2) privative poverty, signifying existential deficiency and the absence of perfections. This distinction is analytical in nature, suggesting that as one ascends the hierarchy of existence toward its apex, effects become increasingly dependent and affirmatively poorer, whereas as we descend toward the lower levels of existence, the beings have a greater privative poverty and weakness. This study employs a documentary and library-based research method for data collection, while its analysis is based on logical and rational examination of the data.
