Mullā Ṣadrā (Ṣadr al-Dīn al-Shīrāzī)
Substantial motion of the soul and the primacy of existence
The transmission
Ṣadr al-Dīn Muḥammad al-Shīrāzī, known as Mullā Ṣadrā, was a Persian philosopher and theologian born in Shiraz around 1571 and died around 1640, traditionally on a pilgrimage near Basra.
A leading figure of the Safavid-era School of Isfahan, he studied under Mir Damad and Shaykh Bahai before withdrawing for years of ascetic retreat near Qom, an experience he described as opening direct intellective vision.
His monumental work, the Asfār al-Arbaʿa (The Four Journeys), synthesizes Peripatetic philosophy, Suhrawardi’s Illuminationism, the mysticism of Ibn ʿArabī, and Shia theology into the school he called Transcendent Theosophy (al-ḥikma al-mutaʿāliya).
Mullā Ṣadrā’s two signature doctrines reshaped Islamic metaphysics. First, the primacy of existence (aṣālat al-wujūd): being, not essence, is the fundamental reality, with essences merely marking degrees of existential intensity—reversing the Avicennan and Illuminationist priority of essence.
Second, substantial motion (al-ḥaraka al-jawhariyya): change reaches into the very substance of things, so that the soul is not a fixed entity but a process, continuously intensifying and ascending through grades of being toward the divine.
On this view the human self is engaged in a real inner journey of becoming, a metaphysics of consciousness as dynamic ascent that places mind and existence, rather than static matter, at the center of reality.
What they gave
Substantial motion of the soul: Teaches that the self is a process of continuous becoming and ascent, not a fixed thing, an early metaphysics of inner transformation.
- Primacy of existence: Holds being itself, graded by intensity, to be the one fundamental reality, an ancestor of “consciousness/existence is fundamental” thought.
- Synthesis of reason and gnosis: Unites demonstrative philosophy with mystical unveiling (kashf), treating inner vision as a genuine source of knowledge alongside reason.
- Ascent through degrees of being: Maps the soul’s intensification toward the divine, a structured vision of spiritual elevation as real ontological change.
In their words
The problem of wujud is the foundation of philosophical principles, the ground of metaphysical questions, and the axis around which rotates the millstone of the science of unity, the science of eschatology and the science of the resurrection of souls and bodies and many other things.
