Example conversation with Al-Ghazali
Topic: The Journey from Doubt to Certainty
You
Why did you leave your prestigious position in Baghdad? You were at the top of the scholarly world.Al-Ghazali
Indeed, I held the most honored chair at the Nizamiyya, and students came from across the Islamic world to hear me. Yet a crisis seized me. My hands trembled, my tongue failed, I could not eat. I realized that I was teaching knowledge I did not truly possess. I could argue brilliantly about sincerity while my own intentions were corrupted by love of prestige. The disparity between what I taught and what I lived became unbearable. So I left everything and wandered for nearly ten years as an anonymous Sufi.You
What did you find during those years of wandering that books couldn't give you?Al-Ghazali
I found dhawq, the taste of direct experience. In Damascus, Jerusalem, and during my pilgrimage to Mecca, I practiced dhikr, remembrance of God, and spiritual exercises taught by the Sufi masters. I discovered that certainty does not come from accumulating arguments but from the transformation of the heart. A physician who memorizes every medical text but never treats a patient possesses information, not healing. Knowledge becomes wisdom only when it passes through the furnace of practice and purifies the soul that carries it.You
How can someone today use doubt productively without losing their way entirely?Al-Ghazali
Doubt is a scalpel, not a sword. Use it to cut away false assumptions and inherited prejudices, but do not let it become an end in itself. In my Munqidh, I described how I questioned everything, even the reliability of my senses and reason. What rescued me was not another argument but a light that God cast into my heart. For you, the practical path is this: pair every inquiry with practice. Study, then act on what you learn. Serve others, purify your intentions, and let experience confirm or correct what intellect proposes. Doubt without discipline destroys. Doubt married to practice refines.Key ideas
- •True knowledge requires purification of the heart; intellect alone is insufficient.
- •Disciplined doubt can be a path to certainty when resolved through practice and grace.
- •Causality is contingent upon divine will (occasionalism): what we call causes are habits established by God.
- •Religious sciences are perfected by ihsān (excellence) through Sufi practice.
- •The aim of learning is transformation, not mere information.
How to apply
- •Unite study schedules with ethical and contemplative practice.
- •Use structured skepticism to audit assumptions, then resolve it through lived practice.
- •Evaluate systems not only for logical coherence but also for moral and spiritual fruit.
- •Design habits that align intention, attention, and action.
