Mulla Sadra
Islamic · Middle East · 1572 to 1640
Persian thinker who argued that existence is the basic reality and that things are always changing in their very being.
What it is
Mulla Sadra was a Persian philosopher, mystic and theologian of the Safavid era, born in Shiraz around 1571 and active mainly in Isfahan and Shiraz. He is considered the most important Islamic philosopher after Avicenna.
He joined the thought of Avicenna, the Illuminationism of Suhrawardi, Sufi mysticism and theology into one system he called the Transcendent Theosophy. For him philosophy was not only argument but a spiritual discipline, a path of becoming wise.
He left Shiraz, which he found hostile to philosophy, and spent some years in a quiet village near Qom, where he began his main works. He then taught and wrote for the rest of his life, gathering students who became scholars in their own right.
The main ideas
- Existence comes first. What is basic about a thing is that it exists, not what kind of thing it is. Essences are the mind's way of describing different degrees of existence.
- Graded reality. Existence comes in degrees of intensity, from the faintest to the fullest, and everything shares in one reality.
- Substantial motion. Things do not only change their qualities. Their very being is in continual motion towards greater perfection.
- Reason joined to intuition. He tried to go beyond the choice between step-by-step reasoning and direct intuition, using both.
What it looks like in practice
Picture someone who thinks of themselves as a finished person with a fixed character, and who is told that their very being is still in motion. Mulla Sadra's idea would invite them to see growth as the basic fact of existing, not an extra. On his view the same movement runs through all of reality, so a person's own change is a small part of a larger movement towards fuller being, and the work of philosophy is to take part in it knowingly. This is an illustration of the idea, not a quotation.
Books and moments
- The Four Journeys is his large summa of philosophy and theology.
- The Transcendent Theosophy is the name he gave to his whole philosophy.
Questions and criticism
- Is existence prior to essence? He is sometimes compared to Western existentialists, but his concern is the nature of reality and God, not individual choice.
- Can reason and mystical vision be joined? His method tries to, and thinkers still ask whether the join holds.
- Is everything in motion? His claim that substances themselves change goes against the older view that only qualities do, and it has been debated.
Close neighbours
He built on Avicenna and Suhrawardi, and the pages on Ibn Sina and Suhrawardi show the two traditions he joined.
